1. Scheduling involves the timing of operations to achieve the efficient movement of units through a
system. The overall objective of scheduling is faster movement of goods and services through a
facility, better customer service and dependable delivery.
2. The four criteria for determining the effectiveness of a scheduling decision are
Minimize completion time
Maximize utilization
Minimize work in process
Minimize customer waiting time
3. Loading means the assignment of jobs to work or procession centers. Operations managers assign
jobs to work centers so that costs, idle time, or completion times are kept to a minimum. Loading

6. What is a due date?
A due date is one of the four most popular priority rules, meaning that the job with the earliest due
date is selected first. The example shown indicates that this method is most effective in category 'd'
which is the average job lateness measurement.
7. Explain the terms flow time and lateness?
Flow time is the period required to complete a specific job or a defined amount of work. The flow
time measures the time each job spends waiting plus the time it takes to be processed. Lateness
refers to coming, occurring, or remaining after the correct, usual, or expected time; delayed

team of experts charged with defusing several time bombs scattered throughout your building? You
can see the bombs; they are of different types. You can tell how long each one will take to defuse.
Given this situation I would most definitely use a shop–floor scheduling rule that caters to the major
issues facing this situation. The fact we can see the bombs but they are of different variety plays a
major factor. We are also faced with a timeline to work with which will determine what scheduling
rule is selected. EDD would be select for several reasons; this would prioritize what bombs need to

be defused first. From there, workers can be assigned to getting that work done. Completion time is
relatively low with high

Explain what is implied by the assumption that decision–makers are rational? How is the
assumption of rationality used in the economic analysis of individual behaviour? In many academic
disciplines much is spoken about rationality and rational choices. Economists generally refer to
'rational' choices and that individuals in economic theory are rational. By rational we mean people
choose options which they perceive to be the best, given the circumstances they are in. In terms of
making rational choices some of the conceivable options for example of going to work would be: ·
Actually going to work. · Staying at home · Going out shopping · Buying a house · Fly to the moon
etc. But with these choices we face ... Show more content on Helpwriting.net ...
However the consequences of making a choice that may seem rational is not always taken into
consideration as in many cases the choice taken may be actually irrational. For example, somebody
deciding or not they should buy a sandwich with limited money, will certainly consider the
immediate satisfaction of their hunger, but it is dependant on the individual how much importance
they would give to the fact that they wouldn't be able to get the bus back home later that night and
would catch a cold from walking back, resulting in days off work and subsequent loss of income. It
could be said therefore that anyone who bought the sandwich would be considered 'irrational'. The
assumption that one is always in possession of all their rational senses is a dangerous one to make. It
can hardly be assumed that the decision of anyone already very drunk on a night out to buy another
alcoholic beverage to be rational .They know that it will result in them being violently sick and lead
to them regretting the purchase in the morning, yet this does occur as their intoxicated state has
robbed them of the power of 'rational' thought. The same can be said of other conditions such as
stress and being in love. In terms of decision–makers, rational decision making operates where "a
decider in an environment must choose among alternative courses of action, each leading to a
different expected environmental outcome, where some outcomes are

Lean Manufacturing & Six Sigma Manufacturing

Lean manufacturing & six sigma Manufacturing:
Six sigma and lean system has the same way of approaching but uses different technology to
achieve the goal. The both procedure lives up to expectations for to dispense with waste and expand
the productivity of the procedure and convey the zero defect items. Recognizable of primary cause
of waste is the fundamental distinction between lean and six sigma. lean innovation says that waste
originates from undesirable steps in the production process which don 't add the value of the final
product while six sigma says that waste is a direct result of variety of diverse procedures.
The focus on lead–time reduction is an simple and effective performance measure to employ (Suri,
1998) where ... Show more content on Helpwriting.net ...
Six sigma has better performance, reduced waste, uniform process output.
Format: Kaizan event format concentrated resources in short time frame. Six sigma has project
format. Resources spread over months.
Scope and Scale: Lean has quick and initial gains, ongoing improvement, suitable for every one and
every part of the business. The scope and scale of six sigma is help to analysis the complex

Lean manufacturing and Theory of Constraints:
The hypothesis of constraints may be an extremely powerful technique for shop floor administration
for a few manufacturers, however in numerous mass customization circumstances it will be hard to
execute because of its substantial dependence on a steady and consistent constraint in the system. At
the point when considering the capacity of TOC to help in making productive mass customization, it
is vital to consider the high variability that will be available. It has been found that once the DBR
component is actualized, the constraint can shift because of variety in the system (Goldratt, 2004),
and these occasional shifts must be recognized and the system adjusted likewise. With mass
customization, numerous organizations will manage high work content variety from every work
piece to the following, accordingly it is likely that the constraint will shift oftentimes, with a higher
impact for low volume

Constraint-Induced Movement Therapy Case Study
Constraint–induced movement therapy (CIMT) is a rehabilitation treatment approach to help
patients restore function on the affected extremity by restraining the unaffected extremity. This
method of therapy focus on the reuse of the more affected extremity caused by medical conditions
such as, cerebral palsy, multiple sclerosis, traumatic brain injury, or a stroke. This type of therapy is
most commonly applied following a stroke because the initial unsuccessful use of the affected
extremity is very discouraging to a stroke survivor. Studies have proven that CIMT increase motor
functional movement and brain activity on the affected side. Before a person can participate in
CIMT, he or she must meet criteria. He or she must be cognitively intact to comprehend the process,
have the ability to begin from a resting position of forearm pronation and wrist flexion, able to
actively extend the wrist at least 20 degrees, and actively extend finger joints at least 10 degrees. ...
The first component involves repetitive, task–oriented training of the affected upper extremity for 6
hours a day for 10 or 15 consecutive weekdays. During the intervention phase, the participant is
supervised by an interventionist as they practice functional task activities such as shaping or task
practice. Shaping is a training method based on principles of behavioral training. The motor
objective is approached by small steps, and each functional activity is practiced for a set of ten 30
trials. Task practice is not structured to be individual trials. It involves functionally based activities
(e.g., writing wrapping a gift) that are performed continuously for a period of 15 – 20

Recently I have participated in the continuous improvement project at my work to improve
productivity and to recreate a process. The name of the project was Kaizen 2016. The Japanese term
KAI and ZEN literally mean "to change" and "for the better" and it has come to symbolize
continuous improvement.
I am trying to put this whole project together by using David Kolb's model of experimental learning.
1. Concrete Experience
The main goal of the project was to increase productivity by decreasing the time being wasted. The
manager, who took all the responsibility of the project and five team members were part of the team.
There was a project sponsor, who guided us and projected our ideas. This project started on August
9th, 2016. At the first meeting, we all sat in the conference room together. Not a sound came from
any of us. Finally, after several minutes, what I felt like an hour, I simply had to say something. I
asked, "Why do we need to change the process?" One member of the team, said, "We need to
change it because I think we are wasting too much time on other things." Another person, a senior
woman, said, "I don't think so we need to change the process. I am comfortable with the current
one." Others laughed. I thought to myself: I didn't want to be in a group with people who didn't take
the project matter seriously. When the meeting ended, my

The Youth Of A New Country
1. Grabbing people's attention with certain programs can be a hard task to achieve, especially if they
don't know your language that well, or they are newcomers to your country. The way I would reach
out to the newcomer youth in the Greater Toronto area would be creating a flier to post around
schools and public places to promote the program, this way the more instances that people see the
flier, the more interested in it they become. Another way of grabbing the attention of newcomers to
pull them into coming to our program would be giving out packages explaining to the parents of the
children what our program can benefit to their children who are being welcomed into a new country.
This makes sure the child's parents are aware of the programs that the YMCA has for them, plus
give them a chance to look over and contemplate if they believe it is going to be a good opportunity
for their children. Lastly, I would develop a presentation, and go into the schools most populated
with newcomer kids to introduce them to the types of programs that they can get involved in. I
would even ask for it to be held outside of normal school hours so their parents would be able to sit
in on the presentation so they are able to get the same information. There is one major barrier the I
need to consider while developing ways to promote the YMCA programs. That barrier is
communication. While most of the people who live in Toronto speak either English or French,
immigrants also in the Greater

Results and Discussion
This application was tested on a singular system, of Tantalum, Rhodium and Palladium (Ta–Rh–Pd).
The metrics that will be analyzed is how well the Phase Mapper Game's solution compared to
AgileFD alone in terms of speed, satisfying constraints, and having a physically meaningful
solution. It should be noted that the user for Phase Mapper Game has much experience working with
the system so the time does not reflect what would be the average for a lay person. The system was
not tested on a lay person however because it has not been developed far enough to be that
accessible. For this test of the application the solutions were compared for when only three solution
patterns were found. Time As seen in Figure 4, the solution patterns found for the Phase Mapper

Resource Constraints Essay
iii. The Constraints
There is always a scarcity of resources such as man, money, machine, material, time, space and
others. The availability and usage of these resources by various activities are represented as linear
equalities and inequalities in terms of decision variables. An LP solution may be accepted provided
these constraints are satisfied by it. Along with resource constraints, one more assumption that act as
a constraint is known as "non– negativity" constraint or restriction. As per this constraint, the
decision variables can take either zero or positive values.

Are Financial Constraints an Important Determination in a...
The Cash Flow Sensitivity of Sash
Research Question Does the link between financial constraints and firms demand for liquidity can
help us identify whether financial constraints are an important determinant of firm behavior.
Contribution Previous scholars, Fazzari, Hubbard, and Petersen, proposed that investment activities
of a firm is limited by the firm's financial situation, which is called financial constraints. When firms
face financial constraints, the firm's investment–cash flow sensitivity is high. When a firm face no
financial constraints, its investment–cash flow sensitivity is low. However this theory was doubtful
by some scholars. In 1997, Kaplan and Zingales propose an exactly opposite theory. In 2001, ...
The authors further test the intuition of our argument by investigating firms' propensity to save cash
out of cash inflow over the business cycle.
Result
The authors use two alternative method to empirically model the cash flow sensitivity of cash. The
first model only include proxies: cash flow and investment opportunities. The second model is
estimated from a method in which a firm's decision to change its cash holdings is modeled as a
function of a number of sources and uses of funds. The result reported in table III is related to the
first model. The set of constrained firms shows significantly positive sensitivities of cash to cash
flow sensitivities. The sensitivity estimates for constrained firms are between 0.051 and 0.062 and
are all statistically significant at better than the 1% level.
The result reported in table IV is related to the second model. This finding is consistent with the
view that there are systematic difference between constrained and unconstrained firms in the way
they conduct their cash policies.
Paper's Findings
By conducting this study, the authors conclude that financial constraints and firm's liquidity demand
can help identify whether financial constraints can

Executive Summary
Introduction Angela Fox and Zooey Caulfield are recent college graduates from State University
with a degree in food and nutrition. With their love for food and nutrition these two friends have
decided to open up a French restaurant in Draperton, which is also the town State University is
located in. They believe their business will prosper because there are no French restaurants in the
area leaving the restaurant to be unique. They acquired a Victorian home just off of Main Street
which is a heavily trafficked area and name their new venture "The Possibility". Though "The
Possibility" has potential, being inexperienced restaurant owners leaves for some potential
problems. Also being recent college graduates it is ... Show more content on Helpwriting.net ...
Symptom: Lack of clientele preference
Cause: opening only French Restaurant in the area
Symptom: Unsure how to reach maximum profit
Cause: never owned restaurant before, budget, must factor in: time of preparation, time of labor,
amount of dishes sold, different profit by type of dinner
The decision Angela and Zooey are now facing is the optimal amount of each dish they can sell to
reach maximum profit when factoring in all of their constraints.
Causes of the Problem Angela and Zooey desire to make a profitable French restaurant. "The
Possibility" has endless of possibilities to prosper if it can resolve the problems which the decision
makers are facing. Their first challenge was not knowing how the customer would take to French
cuisine. This caused problems such as what to put on the menu since excessive waste was not an
option. This problem had a quick alternative for the time being as to only offering a fish or beef
dinner. Though they have narrowed down their menu to a fish dinner and a beef dinner it is
necessary to factor in all the constraints on how many of each type of dinner to sell to reach a
maximum profit. The first constraint is the maximum meals which would be prepared each night.
The decision makers wanted to set a fixed maximum so they can get the right amount of ingredients
and not produce any extra waste. The set number has been decided by the decision

Bartleby, the Scrivener & the Lady with the Dog Essay
A number of the stories studied this semester explore the conflict between social restraint and inner
compulsion. Discuss at least two of the stories in the light of this.
Through an exploration of the boundaries between social constraint and inner compulsion, Melville
and Chekov reveal the restrictions forced upon one's personal desires as they struggle to find a
balance between conflicting values and social norms. Anna and Gurov in 'The Lady with the Dog'
are restrained by the socially expected conventions in their marriages, inhibiting their ability to
express their inner compulsion of desire. Chekov reveals their yearning to escape their individual
lives as they cope with personal troubles by distancing themselves from marriage ... Show more

He uses his employment as a means of escaping social conventions through his monotonous
statement "I would prefer not" (Melville 1998, p. 198), living a life of choice and preference in a
world where preference is non–existent. Bartleby represents a new form of humanity where an
individual has the right to choice rather than living a life of routine through social constraints,
defying all forms of society's restrictions in order to reveal his true desires.
Chekhov explores this concept of conflict through Anna and Gurov's relationship in 'The Lady with
the Dog' as he reveals a need to defy social restraints in order to escape their marriages as this
restricts them from fully embracing their desires. The image of the "long grey fence adorned with
nails" (Chekhov 1998, p. 371), symbolises the confines of marriage keeping them apart, unable to be
free from social restraint. Creating an air of seclusion and limitations, this depiction appears to be
fending off Gurov, producing a feeling of entrapment and isolation as it separates their love. The
image of an old woman, a beggar and a dog walking in and out of the fence freely further
emphasises this lack of freedom they have in their lives; the portrayal of a beggar being the most
illuminating aspect of this passage. Even what is considered as the lowest form of humanity, appears
to show more freedom then what they can as they cannot pass this

Literary Devices In Nuns Fret Not At Their Convent's...
Constraints often have negative connotations, however in many situations they can be comforting
and provide people with a direction. Both physical and conceptual limitations provide comfort
especially when they provide a sense of familiarity. Literary devices such as imagery and irony help
to convey this theme throughout the poem. In Nuns Fret Not at Their Convent's Narrow Room
William Wordsworth uses literary devices, as well as examples of comforting confined spaces, to
prove that having conceptual limitations can be beneficial as well. Wordsworth uses imagery to
convey positive images of confined spaces. The first instance of this is in the introduction of the
poem, "Nuns fret not at their convent's narrow room" (Wordsworth 78). A nun is not unhappy with
her small room because she is able to find peace there. This is where nuns are able to connect with
god. The connections that they feel there helps to provide them with comfort. Even though it may be
a small room, it is what they are familiar with and have grown accustomed to. Over time they
probably haven't noticed the small space of the convent because it has been over shadowed by the
positive memories formed within the building. Imagery is used throughout the poem to continually
convey the theme. All of the images that Wordsworth portrays lead to the same conclusion. Each
image that Wordsworth creates in the poem is of a confined space. However, the subject of the
image is never trying to flee from this place. In many instances they are drawn towards these
compact spaces. All because of the same general reasons, it is comfortable, safe, and familiar.
Wordsworth uses bees in the Peak of Furness–fells to strengthen his point. The imagery used by
Wordsworth depicts how vast the mountains are, "High as the highest Peak of Furness–fells, Will
murmur by the hour of the foxglove bells" (79). The Peak of Furness–fells is a very large, open,
mountain range in England. There is plenty of open space, so the bee can go anywhere it would like.
However, it chooses the small foxglove bell. This is where the bee is happiest because it gives the
bee the pollen that it needs. The bee will continue to return here because it has become comfortable
with the foxglove bell.

Analysis Of The World Bank 's Economic Growth
Review: Rodrik, Dani (2006). Goodbye Washington Consensus, Hello Washington Confusion? A
Review of the World Bank's Economic Growth in the 1990s: Learning from a Decade of Reform.
Journal of Economic Literature
In the past two decades, the Washington Consensus approach codified by John Williamson (1990)
has been one of the most popular terms in the field of development. Consisting lists of reform
agenda, Washington Consensus used to be or at least believed as a 'rule of thumb' policy to improve
economic growth in developing countries. However, due to the undesired result, now the
Washington Consensus have reached its fallacy.
There are rising debates on what will replace the Washington Consensus and the 1990s: Learning
from a Decade of Reform (2005, hereafter Learning from Reform) published by the World Bank was
one of the most regarded document which summarize the result effect of Washington Consensus and
proposed alternatives to complement the approach through institutionalization and foreign aid. Dani
Rodrik in his article Goodbye Washington Consensus, Hello Washington Confusion? A Review of
the World Bank's Economic Growth in the 1990s: Learning from a Decade of Reform is skeptical
that the proposed alternatives will better–suit to replace the pre–sumptive strategy of Washington
Consensus and therefore he posits the Growth Diagnostic Approach that he and his collegue
developed.
In his article, Rodrik interpret how the Learning from Reform summarize the consequences

Background study and Related Works:
In this chapter, we present a detailed discussion of the research on exam timetabling in the last 20
years. In the first decade there has been significant attention of researchers in this area and there has
been a significant contribution in both theoretical and practical sector. Our aim is to discuss about
the achievement made in this area. We have discussed about the barriers and challenges overcame
by the researchers.
First, we defined some constraint from the previous survey papers. Based on the problem we
discussed about the solution and its procedure. We gave a detailed discussion on the algorithms used
to solve the problem. In the last part we explained our problem and compared it with the existing
solutions, why our problem is different than others. We also discuss some important issues which
have come to light concerning and has not been solved yet. Finally, we gave argument on our
procedure of solving the scheduling problem.
Problem defining from the papers:
There are various kinds of timetabling problems including nurse scheduling, transportation
timetabling, educational timetabling and sports timetabling [21]. Among the problems, educational
timetabling is widely used, most important and time consuming task. A quality timetable is the
concern of the administration, because there are many stockholders including students, lecturers and
administrators. Among the educational timetabling, there are school timetabling, university

Theory of Constraints
The Theory of Constraints (TOC) developed by Goldratt and Cox (1986) is a production–flow
management system. In every system there is one process, known as the constraint, which has the
least capacity (or slowest production rate). Output for the entire system is determined by the
production rate of this constraint, or bottleneck. Theory of Constraints is a pull system much like
Toyota's manufacturing system. However, TOC is based on identifying and optimizing the
bottleneck. Because the system cannot produce faster than the bottleneck production rate, the
constraint should be fully utilized. A disadvantage to TOC is that it results in higher constraint
utilization and greater throughput levels.
TOC also improves flow and reduces excess work–in–process inventory by releasing materials only
for those products that are sold. The advantage of TOC over the Toyota system is that when a non–
constraint process is down, the constraint can keep working and rebuild the safety stock. Thus, the
non–constraint process that temporarily is down can catch up with the constraint because it has
excess capacity.
Continuous Improvement (Kaizen)
Continuous improvement, often known as Kaizen, is essentially a small step improvement strategy.
It is based on a belief that continual improvement can be brought about by a continuing series of
small changes. Even if there is a culture of big innovative changes it is argued that these will still

Essay on Freedom and Satan in John Milton’s Paradise Lost
Freedom and Satan in Paradise Lost
Satan's primary operational problem in Paradise Lost is his lack of obedience. The fundamental
misunderstanding which leads to Satan's disobedience is his separation of free will from God's
hierarchical power. In the angel Raphael's account, Satan tells his dominions, "Orders and
Degrees/Jarr not with liberty" (5.792–93). Tempting as this differentiation seems, Satan is mistaken.
Free will and hierarchical power are not mutually exclusive, as Satan suggests, but overlapping
concepts. Even though Satan has been created with sufficient freedom to choose to disobey, he
tacitly acknowledges God's sovereignty when he exercises his choice. Satan is constrained
existentially, from the outset, by ... Show more content on Helpwriting.net ...
But if Satan does only what God wants, there is no external proof that Satan indeed had exercised
his will. Satan cannot be content with mere assent that looks like blind obedience. Dissent, on the
other hand, is absolute proof of Satan's individual will being realized over against God's will. Satan's
intent seems to be to prove the existence of his will rather than, as God wants, to prove the
independently good content of his will. By dissent, Satan shows himself to be more concerned with
himself than with God, with the appearance of free will than with its real content. Here is the second
major constraint under which Satan lies: as a rule, he only recognizes that part of himself which is
disobedient. This constraint, unlike the one natural to Satan's will, is self–imposed.
Satan's pride further constrains him. Because he is able to prove his freedom via dissent, and
because he has ignored the fact that his free will comes from God, Satan thinks (or at least tells the
angels before his own fall) that all heavenly beings including God are "Equally free" (5.792).
Focused on his own freedom, Satan cannot understand that God has even more freedom than he.
When confronted with the hegemonic power of the Son, then, Satan believes that "new Laws" have
been imposed, that God has changed the rules (5.679–80). But this is not a new constraint; it is
merely a new formulation of the Godhead.
According to Raphael, Satan thinks that to acknowledge the Son would be to

Our company manufactures four different formulations of drugs of the same brand–name and in the
final part of the manufacturing process there are three major operations namely mixing of salts,
pelletizing and packing and packaging of drugs into strips. For each variant the time required for
these operations is shown below (in minutes) as is the profit per strip sold.

 As per the current scenario of the labour working in our company, we estimate that, each year, we
have 1,00,000 minutes of mixing, 50,000 minutes of pelletizing time and 60,000 minutes of
packaging time available. How many of each variant should our company make per year and what is
the associated profit?
 Suppose now that we are free to decide how much time to devote to each of the three operations
within the total allowable time. How many of each variant should we make per year and what will
be the associated profit?

Difference Between Total Quality Management
Table I shows a summary of the various approaches and some of their key characteristics. Despite
some differences between Total Quality Management (TQM), the Theory Of Constraints (TOC), Six
Sigma and Lean the desired outcome of each methodology is ultimately customer focused. TQM,
and Lean trace their origins to the quality evolution in Japan shortly after the Second World War
though the concepts within each have developed differently. Many TQM concepts and tools have
become integral parts Lean methodology, but they differ in their primary focus. While six sigma is
often viewed as a direct descendant of TQM it brings a more disciplined approach to process
improvement, organizational structure and focus. TOC was introduced to overcome the perceived
shortcomings of both Lean and TQM. Both were thought to lack focus on the throughput of a
product that was considered to provide a greater benefit in terms of improving an organization's
financial performance.

Using David Kolb 's Model Of Experimental Learning
Recently I have participated in the continuous improvement project at my work to improve
productivity and to recreate a process. The name of the project was Kaizen 2016. The Japanese term
KAI and ZEN literally mean "to change" and "for the better" and it has come to symbolize
continuous improvement. I am trying to put this whole project together by using David Kolb's
model of experimental learning. 1. Concrete Experience The main goal of the project was to
increase productivity by decreasing the time being wasted. The manager, who took all the
responsibility of the project and five team members were part of the team. There was a project
sponsor, who guided us and projected our ideas. This project started on August 9th, 2016. In the first
meeting, we all sat in the conference room together. Not a sound came from any of us. Finally, after
several minutes, what I felt like an hour, I simply had to say something. I asked, "Why do we need
to change the process?" One member of the team, said, "We need to change it because I think we are
wasting too much time on other things." Another person, a senior woman, said, "I don't think so we
need to change the process. I am comfortable with the current one." Others laughed. I thought to
myself: I didn't want to be in a group with people who didn't take the project matter seriously. When
the meeting ended, my perceptions of the group had somehow changed. Maybe this was a good
group to be in after all. Some members had similar interests

Video Case: Constraint Management at Southwest Airlines
Question 1: Analyze Southwest's passenger boarding process using the Theory of Constraints.
Southwest Airlines is an airline company that has set industry benchmarks of having the best
turnaround ratios, in an industry where lead time during different operations is very time consuming.
Southwest currently boasts a rapid gate–turnaround of 25 minutes or less, and it demonstrates how
attention to activities pertaining to ground operations (including cleaning of the aircraft, fuelling and
flight preparation) can help the company in being so operationally efficient. Customers rave about
low fares, exceptional customer service, and the biggest competitive advantage that Southwest has
... Show more content on Helpwriting.net ...
Constraints in the boarding process are related to the boarding sequence of passengers; in order for
Southwest to manage its constraints, they need to improve the boarding sequence of passengers to
make it as fast as possible which in turn would lead to better turnaround times (faster boarding
times).
Question 2: Which boarding scenario among the different ones proposed would you recommend for
implementation? Why?
The seven different alternate boarding scenarios that were designed were: * New family pre–
boarding behind the "A" group of first–to–board passengers. This method would give priority to
passengers that are travelling with families and give them exclusive access to the aircraft first. *
Family pre–boarding before anyone else, but seating choices limited on–board to behind the wing.
Similar to the first scenario, this would give families priority in the boarding sequence but would
restrict them to certain sections of the aircraft. * Six boarding groups (within A–B–C groups) instead
of the original three A–B–C groups. This would allow for better division of the boarding sequence
since the groups have been doubled. * Assigned boarding gate line positions based on both boarding
group and gate arrival time. This scenario would allow Southwest to get rid of its current single line
philosophy. * Single

spider monkey optimization algorithm" in which a Lévy flight spider monkey optimization
(LFSMO) algorithm was proposed to solve the standard Optimal power flow (OPF) problem for
IEEE 30–bus system. The exploitation capacity of SMO was increased in the proposed algorithm.
LFSMO was tested over 25 benchmark functions and its performance was examined. It was found
that LFSMO gave desirable outcomes than the original SMO.
In 2017, S. Kayalvizhi et. al. [49] presented a paper "Frequency Control of Micro Grid with Wind

gains of PI controllers which helps in regulating the frequency of the micro grid. A typical micro
grid test system and a real time micro grid setup at British Columbia are the two case studies
considered, in which the frequency control is implemented. The implementation is done in two–step
search process; in the first place, levy flights do the random search and after that SMO does a
thorough local search. Results demonstrate that the proposed method outperforms the results of

The Goal: A Process Of Ongoing Improvement
The world of business evolves over time through new products, services and technical advances. As
it changes, it is also important to re–evaluate how success is measured currently in the business
field. It is possible that new methods may need to be developed or identified to truly identify issues
or success within an organization. The Goal: A Process of Ongoing Improvement provides insight
on how a company that was set in its old ways of measurements did not conform to new technology
that was introduced on the floor. This was creating a false sense of success when in fact money was
being lost. It also introduces the Theory of Constraint.

First, they IDENTIFY constraints, second, they EXPLOIT the constraint. Third, they
SUBORDINATE everything else. The fourth step is to ELEVATE the system's constraints, and the
fifth step is to go back to the first step if any of the constraints are broken, but without allowing
inertia to create a system's constraint.
In our textbook, it states that operations managers are to enhance the ratio of outputs to inputs
(Heizer & Render, 2017). Improving productivity means improving efficiency which can be
achieved in two ways: reducing inputs while keeping output constant or increasing output while
keeping inputs constant (Heizer & Render, 2017). This is what Alex did in his plant. He increased
output while keeping inputs constant.
The book was very easy to read and the first person narrative helped me really understand that this is
a thought process. I do not believe that the book would have been as effective if it was written in a
different narrative style. I feel this method allows the reader to really understand Alex and how he
reached the outcome that he did. I personally feel that the Theory of constraints can be applied to
almost any field of business, regardless of whether the products are tangible or

Objective Agrifarm Company's main objective is to determine the proper distribution, within a
distribution network, to minimize the total shipping costs to deliver carloads from origin to the hubs
and finally to the customers. To do so, we are given two distribution cost tables that explain the
processing center shipping costs, meaning origin to hubs, and the customer shipping costs, meaning
from hubs to the final customer. Therefore, the cost to ship rail cars of grain from the origins and
hubs will determine the proper distribution of rail cars from origin to destination. Solution Our
optimal solution (total shipping cost) to meet all ten constraints is $513,000. Origin Muncie will not
ship to hub Louisville but will ship 3 rail cars of grain to hub Cincinnati. Origin Brazil will ship 6
rail cars of grain to hub Louisville but will not ship hub Cincinnati. Origin Xenia will not ship to
hub Louisville but will ship 5 rail cars to hub Cincinnati. Origin Dummy will ship 1 rail car to hub
Louisville but will not ship to hub Cincinnati. Hub Louisville will ship 2 rail cars to customer

The Constraints Of Constraint Management
A constraint is anything that limits a system from achieving higher performance relative to its goal.
Constraint management seeks to help managers at all levels of an organization. It ensures that they
maintain proper focus on the factors that are most critical to overall success of system constraints.
Constraint Management efforts can immediately resolve extremely negative effects from machine,
labor, and process inefficiencies, and have the ability to fund an entire transition to lean through
substantial increases in throughput.
There are three rules to constraint management. They are identifying system constraints, exploiting
the constraint, and improving the constraint gaps. "A business owner or supervisor using the
constraint model of management can't focus employees on system constraints without first
identifying those constraints. Naming the constraints that are integral to a company 's success,
including company work policies and manufacturing standards, sets up clear expectations for
employees regarding performance and productivity. Exploiting the constraint is the process by
which a company maximizes profit through use of a given system constraint. Tying the completion
of project steps by nonconstrained resources to completion by constrained resources improves
operational efficiency and closes gaps in schedules." (Lister, 2016).
On a daily basis, a company's constraint is the major regulating factor that decreases the amount of

The other two extreme points must be solved using both line equations simultaneously: Of the five
extreme points, one point will provide the maximum profit contribution.
Solving for the extreme point where the color and nutrient lines intersect subtract the two equations:
1) 6X + 15Y = 90 Multiply this equation by 2 to eliminate the X variable
4X + 4Y = 30 Multiply this equation by 3 to eliminate the X variable
2) 12X + 30Y = 180
12X + 12Y = 90 Subtract equation two from equation one 18Y = 90 Y = 5 Substituting Y = 5 back
into the first equation
6X + 15(5) = 90 6X + 75 = 90 6X = 15 X = 2.5 Extreme point = (2.5,5)

How High Energy X Rays Are Used On A Crystal Essay
Figure 1: Top: Shows how high energy X–rays are used on a crystal to create an XRD pattern (Law
2009). Bottom: An example XRD pattern for a sample point (Xue et al. 2016). Then the collected
XRD patterns are organized and the underlying structures are found. Meaning that for each library
there should be a small number of underlying XRD patterns, usually less than ten, such that every
pattern in the library can be reconstructed as a linear combination of these underlying patterns.
These underlying patterns can then be used to interpret the crystal structure of each sample point, as
well as give insights into the material properties of each sample point. These underlying XRD
patterns are often called a phase. This signal de–mixing of material systems is referred to as the
phase mapping problem. Using traditional methods material scientists can process approximately ten
XRD patterns per day, whereas sample points are generated on the order of thousands per day
(Gregoire et al. 2009; 2014). Clearly there is a need for a scalable algorithmic approach to address
this problem. To address this problem the novel solver AgileFD was created that is based on
convolutive non–negative matrix factorization (cNMF), which has been previously used for source
separation problems (Smaragdis 2004; Mørup and Schmidt 2006). AgileFD uses lightweight
iterative update rules that allows for fast solutions, on the order of minutes (Xue et al. 2016).
However the many constraints that a solution must

Traditional Compatibilism Examples
When it comes to free will, the traditional compatibilist has a simple outlook on a subject that any
average human being can grasp. On the outside, it may look confusing, but traditional compatibilism
is simple once you get through the vocabulary and a few examples. In this essay, I will cover the
traditional compatibilists' analysis on free will, give an example of a counterexample to traditional
compatibilism, and my thoughts on why or why not the counterexample is successful in rejecting the
traditional compatibilist analysis of free will. To start off, the traditional compatibilist "suggests two
conditions for freedom" (Rauhut, 2011, p. 90). One of these conditions is that the specific action is
caused by that person's own will. This ... Show more content on Helpwriting.net ...
However, can John act otherwise? The brain injury he suffers from prevents John from having the
desire to consume white things, like the glass of milk. This case is supposed to show that John does
not have free will since he is acting out of his desire to not drink the milk since it's white, but he
could not have acted otherwise. The case satisfies condition number one for the traditional
compatibilist analysis of free will. John is acting on his will to drink something that is not white.
While this may be true, this case tries to say that John could not have done any other action, failing
the second condition of the analysis of free will from a traditional compatibilist view. In my eyes, I
do not believe that the Brain Injury case is a counterexample to the traditional compatibilist analysis
of free will. In the case, John is having the desire to drink. Whether this be water or milk, is
determined by his feelings, desires, hopes, beliefs, and wishes. Drinking the water is a desire that
John has. Because of this, the first condition for the traditional compatibilist analysis of free will is
achieved. The second condition for the traditional compatibilist analysis of free will is that the
person is acting without any constraints. While John cannot have the desire to drink milk, that does
not stop him from actually drinking the milk. For example, I hate seafood. As of right now, I do not
have the desire to eat

Three Rules Of Constraint Management And Supply Chain...
2.4 CONSTRAINT MANAGEMENT AND SUPPLY CHAIN MANAGEMENT What is Constraint
Management? Constraint management is a tool that supervisors and other management personnel
use to help employees sustain task focus. According to Goal Systems International, a Washington–
based business consulting firm, constraint management try to help employees and supervisors
remain locked in on the most important element of business success: system constraints. These
constraints, or basic conditions to accomplishment a goal, differ by business and can include
meeting manufacturing output quotas, completing products in a well–timed manner or obtaining
particular customer satisfaction scores on product surveys. Constraint management believes that
losing focus on these key essentials can facing disaster for a workforce and the business as a whole.
The constraint management model recognizes performance standards for employees and try to
improve operational efficiency. A business is using constraint management requires structured
schedules for assembling raw materials, creating products and distributing products to consumers.
Performed properly, this model of management can significantly improve the lag time between steps
in a company's production process. There are three Rules of Constraint Management which is

The most risky consequence of the scenario is excess of inventories in the Supply Chain. What is the
reason does inventory increase? Theory of Constraint prove that, even with the use of predictable
tools of the Supply Chain Management, there is still a significant waste with inventory in the Supply
Chain. This problem will be clarified in the following
