Engineering costs include direct costs like labor, materials, and utilities along with indirect costs like overhead. Cost estimating is necessary for economic analysis by approximating the costs of resources and activities. Costs can be classified as fixed, variable, direct, indirect, sunk, opportunity, recurring, and non-recurring. Life-cycle costs consider all costs over the lifetime of a product. Estimating techniques include per-unit models, work breakdown structure models, and using cost indices to adjust for inflation.

Levelwise PageRank with Loop-Based Dead End Handling Strategy : SHORT REPORT ...Subhajit Sahu
Abstract — Levelwise PageRank is an alternative method of PageRank computation which decomposes the input graph into a directed acyclic block-graph of strongly connected components, and processes them in topological order, one level at a time. This enables calculation for ranks in a distributed fashion without per-iteration communication, unlike the standard method where all vertices are processed in each iteration. It however comes with a precondition of the absence of dead ends in the input graph. Here, the native non-distributed performance of Levelwise PageRank was compared against Monolithic PageRank on a CPU as well as a GPU. To ensure a fair comparison, Monolithic PageRank was also performed on a graph where vertices were split by components. Results indicate that Levelwise PageRank is about as fast as Monolithic PageRank on the CPU, but quite a bit slower on the GPU. Slowdown on the GPU is likely caused by a large submission of small workloads, and expected to be non-issue when the computation is performed on massive graphs.

4. Engineering Costs and Cost Estimating
Engineering Costs: Value of the economic resources used in the
production of goods and services.
Examples: Land, labor, capital or initial investment, wages and
salaries, material purchases, utilities
Cost estimating: Approximating the cost of resources or activities
Cost estimating is necessary for any economic analysis
Key Question: Where do the numbers we use in an engineering
economic analysis come from?
When working in industry, you may need to consult with
professional accountants to obtain such information
5. Classification of Costs
Fixed Costs:
Costs that do not vary (i.e., constant and unchanging regardless of the level of the
activity.
Variable Costs:
Costs that vary in total with the quantity of output or other measures of activity level.
Total Cost is the sum of Fixed Cost and Variable Cost.
Direct Costs:
Cost that can be reasonably measured and allocated to a specific output or work activity.
Indirect/Overhead Cost:
Cost that it is difficult to attribute or allocate to a specific output or work activity.
6. Example 2-1
Amin plans to charter a bus to take people to see some event
show in the city. He categorized his costs at shown below:
Which of the costs are fixed and which are variablecosts?
How do we compute Amin’s total cost if he takes n people to City?
Total Cost = Fixed cost + Variable cost
=$225 + $20 n
7. Average and Marginal Costs
Average Cost: Computed as total cost divided by the number of
units produced.
Marginal Cost: The change in total cost that arises when the quantity
produced changes by one unit; i.e. the cost to produce one more unit.
Avg. Cost = TC/n
= ($225+$20n)/n
For n = 33, TC = $885
Avg. Cost = $885/30 = $29.50
Total cost can be calculated from
an average cost value For n =35:
¨ TC ¹ 35*($29.50) = $ 1,032.50
8. Example 2-2
Do we have enough information yet to decide how much money Amin will make on his venture? What else must we
know?
Amin needs to know his total revenue
Amin knows that similar ventures in
the past have charged $35 per person,
so that is what he decides to charge
Total Revenue = 35n (for n people)
Total profit = Total Revenue – Total Cost
35n – (225 + 20n) = 15n – 225
Question: How many people does
Amin need to break even?
(not lose money on his venture)
Solve: 15 n – 225 = 0 => n=15
more than 15, he makes money
9. BreakevenAnalysis
Where is the
Loss Region?
Where is the
Profit Region?
Where is the
Breakeven Point?
It is the point where
total revenue received
equals total costs
associated with the sale
of the product
10. Profit and Loss Terms (non-linear cost and
revenue)
Total revenue =
Unit price x units sold
Breakeven:
total revenue = total costs
Just getting by
Profitregion:
total revenue > total costs
Putting money in the bank
Lossregion:
total revenue < total costs
Going into debt
11. Sunk (Past) Costs
A sunk cost is money already spent due to a pastdecision.
As engineering economists we deal with present and future opportunities
We must be careful not to be influenced by the past
Disregard sunk costs in engineering economic analysis
Example: Suppose that three years ago you bought a laptop PC for $2,000.
How likely is it that you can sell it today for what it cost?
Suppose you can sell the laptop today for $400. Does the
$2000 purchase cost have any effect on the selling price today?
The $2,000 is a sunk cost. It has no influence on the
present opportunity to sell the laptop for $400.
12. Opportunity (Future) Cost
An opportunity cost is a benefit that is foregone by engaging a
business resource in a chosen activity instead of engaging that same
resource in the foregone activity.
Example: Suppose your wealthy uncle gives you
$75,000 when you graduate from high school. It is enough to put you through
college (5 years at $15,000 per year). It is also enough for you to open a
business making web pages for small companies instead of going to
college. You estimate you would make $20,000 per year with this business.
If you decide to go to college you give up the opportunity to
make $20,000 per year
Your opportunity cost is $20,000
Your total cost per year is $35,000
13. Recurring and Non-Recurring Costs
Recurring costs are those expenses that are known, anticipated, and occur at regular intervals.
These costs can be modeled as cash flows.
Non-recurring costs are one-of-a-kind (one-time) event that
occurs at irregular intervals.
They are difficult to plan for or anticipate.
Example: A company decided to landscape a lot of ground and then care for it. Which are recurring and
which are non-recurring costs the company incur?
Remove existing trees, vegetation
Have land graded with bulldozer
Have yard planted with grass
Plant shrubs, trees
Mow grass
Fertilize grass, shrubs
Water grass, shrubs
14. Incremental Cost
Incremental Cost is the additional cost
that results from selecting one alternative
over another.
It is the difference in cost between two
alternative investments or activities.
16. Solution
Let's look more closely at each of the data items.
Distributor's purchase price 3 years ago: This is a
sunk cost that should not be considered in setting the
price today.
Distributor's storage costs to date: The storage costs
for keeping the pumps in inventory are sunk costs; that
is, they have been paid. Hence they should not
influence the pricing decision.
17. Solution
Distributor's list price 3 years ago: If there have been no willing buyers in the
past 3 years at this price, it is unlikely that a buyer will emerge in the future.
This past list price should have no influence on the current pricing decision.
Current list price of newer pumps: Newer pumps now include technology and
features that have made the older pumps less valuable. Directly comparing
the older pumps to those with new technology is misleading. However, the
price of the new pumps and the value of the new features help determine the
market value of the old pumps.
18. Solution
Amount offered from a buyer 2 years ago: This is a forgone opportunity. At
the time of
the offer, the company chose to keep the lot and thus the $5000 offered
became an
opportunity cost for keeping the pumps. This amount should not influence
the current
pricing decision.
Current price the lot could bring: The price a willing buyer in the
marketplace offers is
called the asset's market value. The lot of old pumps in question is believed
to have a
current market value of $3000.
19. Cash Costs vs. Book Costs
Cash Costs: require the cash transaction of dollars out of
one person’s pocket into the pocket of someone else.
Book Costs: cost of a past transaction that is recorded in a
book (accounting book) of a firm.
Do not represent cash flows
Not included in engineering economic analysis
One exception is for asset depreciation (used for tax purposes)
Example: You got offers to sell your car for $6,000 (i.e., the book value of your car
is $6,000). The book value can be thought of as the book cost. If you actually sell
the car to a friend for $5,500, then the cash cost to your friend is
$5,500.
20. Life-Cycle Costs
Life-cycle Costs are the summation of all costs, both recurring and nonrecurring,
related to a product, structure, system, or service during its lifetime.
Products go through a life cycle in phases:
1. Assessment & Justification
2. Conceptual or Preliminary Design
3. Detailed Design
4. Production or Construction
5. Operational Use
6. Decline and Retirement
Engineers should consider all life-cycle costs when designing
products and the systems that produce them.
About 70-90% of all costs are set during the design phases when only 10-30% of
cumulative life-cycle costs have been spent.
22. Cost Estimating
Engineering economic analysis is future based.
Future consequences (costs and benefits) of current decisions and require estimating.
Estimated costs and benefits are not known with certainty.
The more accurate the estimate, the more reliable the decision.
Difficulties arise due to an uncertain future.
Types of estimates:
Rough: gut level; Inaccurate; -30% to +60%.
Semi-detailed: based on historical records; Reasonably sophisticated and accurate; -15%
to +20%.
Detailed: based on specifications and cost models; Very accurate; -3% to +5%.
One-of-a-kind or first time projects: Few such projects in engineering economic analysis.
Estimator experience and knowledge è better quality (and more reliable)
estimates.
23. Estimating Cost Using Per-Unit Cost
Uses ―per unit factor to develop estimate
Very simple yet useful technique for rough estimates
Commonly used in construction industry
Examples:
Service cost per costumer
Safetyper employee
Gasoline cost per mile
Maintenance cost per window
Mileage cost per vehicle
Utility cost per square foot of floor space
Example: A contractor gave you a quote to build you a house for $250 per square
meter. What’s your cost to build a 200 sq. meter-house?
Ans. Cost = 250 x 200 = $50,000
24. (Estimating Cost Using WBS Cost (Segmenting Model
Work Breakdown Structure (WBS) is a graphical tool widely used in the
project planning process.
It organizes all of the project work by placing elements of work into
logical groupings; thus, providing a convenient and logical structure for
estimating the cost of each activity.
25. Cost Estimating Using Cost Indices
Governments usually publish cost index data for labor,
construction, and materials.
The best-known example is the consumer price index (CPI), a
measure of inflation.
The measure is scaled, so it is only the relative values of any two
measures that are meaningful.
For example, in 1920, the measure was about 20; in 1997 it was
about 160. The conclusion is that one would have to spend 160/20,
or 8 times as much in 1997 as in 1920 for the same consumables.
Cost indices work in the same way as price indices.
Cost indices are dimensionless.
26. Cost Estimating Using Cost Indices
Example 2-7:Miriam needs to estimate
annual labor cost for a new plant. For a
similar facility built 3 yrs ago, annual labor
cost was $2,455,000. CPI was at 544 3 yrs
ago but it is 715 today.
27. Estimating Benefits
For the most part, we can use exactly the same app
roach to estimate benefits as to estimate costs:
Fixed and variable benefits
Recurring and non-recurring benefits
Incremental benefits
Life-cycle benefits
Rough, semi-detailed, and detailed benefit estimates
Difficulties in estimation
Segmentation and index models
Major differences between benefit and cost estimation:
Costs are more likely to be underestimated
Benefits are most likely to be overestimated
Benefits tend to occur further in the future than costs
29. Cash Flow Diagrams
A Cash Flow Diagram (CFD) summarizes the costs and benefits of a project
It illustrates the size, sign, and timing of individual cash flows
The time line is a horizontal line divided into equal periods such as days, months, or
years.
The end of one period is the beginning of the next one.
Each cash flow, such as a payment or receipt, is plotted along this line at the beginning
or end of the period in which it occurs.
Arrows: usual interpretation is positive (upward) for cash inflows (revenues) and
negative (Downward) for cash outflows (expenses).
Length of the arrow represents the magnitude ($) of the cash flow.
It is essential to use only one perspective in any CFD.
One person’s payment (cash outflow with – sign) is another
person’s receipt (cash inflow with + sign)
31. Categories of Cash Flows
1. First cost ≡ construction, purchase, or installation expense.
2. Operations and maintenance ≡ annual expense.
3. Salvage value ≡ receipt at project termination.
4. Revenues ≡ annual receipts due to sale of products.
5. Overhaul ≡ major capital expenditure occurring during life of
asset.
32. A concrete aggregate mix is required to contain at least 31% sand by
volume for proper batching. One source of material, which has 25%
sand and 75% coarse aggregate, sells for $3 per cubic meter (m3).
Another source, which has 40% sand and 60% coarse aggregate, sells
for $4.4/m3.
Determine the least cost per cubic meter of blended aggregates.
Example:
33. The least cost of blended aggregates will result from maximum use of the
lower-cost material. The higher-cost material will be used to increase the
proportion of sand up to the minimum level (31%) specified. ..
Let x = Portion of blended aggregates from $3.00/m3 source
1 - x =Portion of blended aggregates from $4.40/m3 source
Sand Balance
x(0.25) + (1 -x) (0.40) = 0.31
0.25x + 0.40- 0.04x =0.31 =0.60
Thus the blended aggregates will contain
60% of $3.00/m3 material
40% of $4.40/m3 material
Solution
34. The least cost per cubic meter of blended.aggregates.is
0.60($3.00) + 0.40($4.40) = 1.8+1.76
=$3.56/m3
Solution
35. A machine part is manufactured at a unit cost of 0.4$ for material
and 0.15$ for direct labor. An investment of $500,000 in tooling is
required. The order calls for 3 million pieces. Halfway through the
order, a new method of manufacture can be put into effect that wi11
reduce the unit costs to 0.34$ for material and 0.1$ for direct labor
but it will require 100,000$ for additional tooling. This tooling will
not be useful for future orders. Other costs are allocated at 2.5 times
the direct labor cost. What if anything, should be done?
Example:
36. Since there is only one way to handle first 1.5 million pieces, our problem
concerns only the second half of the order.
Alternative A: Continue with Present Method
Cost for remaining 1,500,000 pieces = $1,387,500
Solution
Material cost 1,500,000pieces x 0.4= $600,000
Direct labor cost 1,500,000pieces x 0.15= $225,000
Other costs 2.50 x direct labor cost = $562,500
37. Alternative B: Change the ManufacturingMethod
Cost for remaining 1,500,000 pieces = $1,135,000
Before making a final decision, one should closely examine the Other costs to
see that they do, in fact, vary as the Direct labor cost varies. Assuming they do,
the decision would be to change the manufacturing method.
Solution
Additional tooling $100,000
cost
Material cost 1,500,000pieces x 0.34= $510,000
Direct labor cost 1,500,000pieces x 0.1= $150,000
Other costs 2.50 x direct labor cost = $375,000
