This document proposes using multi-criteria decision making (MCDM) approaches, specifically the Analytic Hierarchy Process (AHP) and Technique for Order Preference by Similarity to Ideal Solution (TOPSIS), to help users select a mobile phone. It outlines the evaluation process, which involves identifying important mobile phone selection criteria, calculating criteria weights using AHP, and then using TOPSIS to rank mobile phone alternatives based on how close they are to an ideal solution and how far they are from a negative ideal solution. The document provides examples of building pairwise comparison matrices in AHP and calculating ideal and non-ideal solutions and alternative distances in TOPSIS to demonstrate the selection approach.
Contractors play an important role in any construction project. Perhaps the most important decision is the selection of contractor by the employer prior to the implementation of the project. AHP is one of the main mathematical models currently available to support the decision theory, particularly for construction contractor prequalification.

Decision Making Using The Analytic Hierarchy ProcessVaibhav Gaikwad
Analytic Hierarchy Process (AHP) is an
effective tool for dealing with complex decision making,
and may aid the decision maker to set priorities and
make the best decision. By reducing complex decisions
to a series of pairwise comparisons, and then
synthesizing the results, the AHP helps to capture both
subjective and objective aspects of a decision. In
addition, the AHP incorporates a useful technique for
checking the consistency of the decision maker’s
evaluations, thus reducing the bias in the decision
making process. In this paper we give special emphasis
to departure from consistency and its measurement and
to the use of absolute and relative measurement,
providing examples and justification for rank
preservation and reversal in relative measurement.

Selection of Fuel by Using Analytical Hierarchy ProcessIJERA Editor
Selection of fuel is a very important and critical decision one has to make. Various criteria are to be considered while selecting a fuel. Some of important criteria are Fuel Economy, Availability of fuel, Pollution from vehicle, Maintenance of the vehicle. Selection of best fuel is a complex situation. It needs a multi-criteria analysis. Earlier, the solution to the problem were found by applying classical numerical methods which took into account only technical and economic merits of the various alternatives. By applying multi-criteria tools, it is possible to obtain more realistic results. This paper gives a systematic analysis for selection of fuel by using Analytical Hierarchy Process (AHP). This is a multi-criteria decision making process. By using AHP we can select the fuel by comparing various factors in a mathematical model. This is a scientific method to find out the best fuel by making pairwise comparisons.

Supplier ranking and selection in a bakeryIOSR Journals
Supplier evaluation and selection is a fundamental problem in supply chain management. Many
companies may not know how to evaluate proposed suppliers to integrate the different criteria upon which they
want to make their decision. A number of techniques have been employed to solve this problem but were not
able tosufficiently incorporate qualitative criteria into consideration for estimation of their alternatives.
A multi-criteria decision-making (MCDM) methodology, the Analytical Hierarchy Process (AHP), which takes
into consideration both quantitative and qualitative criteria, was used to evaluate three suppliers of improvers
(a major ingredient) for bread production in a bakery,UIB, in southwest Nigeria. This method uses a ranking
scale when comparing alternatives. A consistency ratio is estimated when data have been collected to check for
the consistency of judgments to ensure an accurate result is obtained with the method.
It was discovered that Supplier C adds more value to UIB because it had the highest priority weight of 0.346,
although it was keenly followed by suppliers B and C with weights 0.336 and 0.317 respectively.
Results showed that each supplier fared well under one criteria or the other and there was a generally
good performance from all suppliers.

Plant location selection by using MCDM methodsIJERA Editor
Plant location selection has a critical impact on the performance of manufacturing companies. The cost associated with acquiring the land and facility construction makes the location selection a long-term investment decision. The preeminent location is that which results in higher economic benefits through increased productivity and good distribution network. Both potential qualitative and quantitative criteria’s are to be considered for selecting the proper plant location from a given set of alternatives. Consequently, from the literature survey, it is found that the Multi criteria decision-making (MCDM) is found to be an effective approach to solve the location selection problems. In the present research, an integrated decision-making methodology is designed which employs the two well-known decision making techniques, namely Analytical hierarchy process (AHP), and Preference ranking organization method for enrichment evaluations (PROMETHEE-II) in order to make the best use of information available, either implicitly or explicitly. It is analyze the structure for the solution of plant location problems and to obtain weights of the selected criteria’s. PROMETHEE-II is employed to solve decision-making problems with multiple conflicting criteria and alternatives.

The use of Ready Mixed Concrete (RMC) by the construction industry in most industrialized
countries is now well established. With the help of going over expertise of experts and their relevant
specialized literature, effective Criterias in Ready Mixed Concrete (RMC) selection and the Criterias
which will be used in their evaluation is extracted. For TOPSIS, the computations were carried out
using Microsoft Excel 2013. The weight of the Criterias is calculated first through Analytic
Hierarchy Process (AHP) and then it is analyzed by Technique for Order Preference by Similarity to
Ideal Solution (TOPSIS) method. The respondents were selected from various construction
occupancy mainly Ready Mixed Concrete (RMC) Plant Managers, Consultants and Contractors.
Total 100 Survey Questionnaires were distributed to Respondents in Anand, Nadiad, Vadodara,
Ahmedabad, from which 60 Responses were collected as per sample size calculation, in that 21 were
from Ready Mixed Concrete (RMC) Plant Managers, 26 were from consultants and 13 were from
contractors.The problem solution result shows: Respondent no. 3 (R3) is best because of its largest
weight age and Respondent no. 25 (R25) is worse because of its smallest weightage.

Enterprise Excellence is Inclusive Excellence.pdfKaiNexus
Enterprise excellence and inclusive excellence are closely linked, and real-world challenges have shown that both are essential to the success of any organization. To achieve enterprise excellence, organizations must focus on improving their operations and processes while creating an inclusive environment that engages everyone. In this interactive session, the facilitator will highlight commonly established business practices and how they limit our ability to engage everyone every day. More importantly, though, participants will likely gain increased awareness of what we can do differently to maximize enterprise excellence through deliberate inclusion.
What is Enterprise Excellence?
Enterprise Excellence is a holistic approach that's aimed at achieving world-class performance across all aspects of the organization.
What might I learn?
A way to engage all in creating Inclusive Excellence. Lessons from the US military and their parallels to the story of Harry Potter. How belt systems and CI teams can destroy inclusive practices. How leadership language invites people to the party. There are three things leaders can do to engage everyone every day: maximizing psychological safety to create environments where folks learn, contribute, and challenge the status quo.
Who might benefit? Anyone and everyone leading folks from the shop floor to top floor.

7. MCDM
MCDM is a powerful tool used widely for
evaluating and ranking problems containing
multiple, usually conflicting criteria.
MCDM refers to find the best opinion from all
of the feasible alternatives in the presence of
multiple decision criteria.
MCDM helps offer recommendations when
decisions involve trade-offs among different
decision criteria.
The MCDM generally enable to structure the
problem clearly and systematically. 7
8. MCDM Methods
Some MCDM methods: Priority

Well accepted by decision makers.
Can be used for multiple decision makers.
17
18. AHP Procedure – Build the
Hierarchy Very similar to hierarchical value structure
– Goal on top (Fundamental Objective)
– Decompose into sub-goals (Means objectives)
– Further decomposition as necessary
– Identify criteria (attributes) to measure
achievement of goals (attributes and objectives)
– Alternatives added to bottom
– Different from decision tree
– Alternatives show up in decision nodes
– Alternatives affected by uncertain events
– Alternatives connected to all criteria
18
22. AHP Steps (Step 1)
Step 1:
AHP uses several small sub problems to
present a complex decision problem.
Thus, the first act is to decompose the
decision problem into a hierarchy with:
a goal at the top
criteria and sub-criteria at sub-levels
and alternatives at the bottom
22
26. AHP Steps (Step 2)
Step 2:
The Decision Matrix, Decision Vector
(Saaty's nine-point scale), must constructed.
Use the fundamental 1–9 scale defined by
Saaty to assess the priority score.
The decision matrix involves the
assessments of each alternative in respect to
the decision criteria.
The decision vector involves the criteria's
preferences. 26
27. 1 -9 Scale

27
31. AHP Steps (Step 3)
Step 3:
Pairwise Comparison Matrix
Compare the pairs of the elements of the
constructed hierarchy.
The aim is to set their relative priorities with
respect to each of the elements at the next
higher level.
31
33. Pairwise Comparison
Matrix
Ways to build pairwise comparison matrix:
1) Build From Decision Vector
2) Build Directly with solicit from user

Is Pairwise Comparison Matrix Consistent?
Consistency Ratio
Reflect the consistency of decision maker's

39
40. Consistency
Ratings should be consistent in two ways:
(1) Ratings should be transitive
– That means that
If A is better than B
and B is better than C
then A must be better than C
(2) Ratings should be numerically consistent
– In car example we made 1 more comparison
than we needed
We know that P = 3M and P = 5G
3M = 5G M = (5/3)G 40

Step 6:
Calculate weight vector!
Multiply weight vector by weight
coefficients of the elements at the higher
levels, until the top of the hierarchy is
reached.

56. TOPSIS
Technique for Order Preference by Similarity
to Ideal Solution (TOPSIS)
TOPSIS is based on positive and negative
ideal solutions.
Solutions are determined in respect to the
distance of each alternative to the best and
the worst performing alternative.
The alternative ratings and criterion
weights, must pass from AHP phase to

57. Evaluating Alternatives by
TOPSIS TOPSIS method, which is based on choosing the
best alternative having the:
Shortest distance to the ideal solution
Farthest distance from the negative-ideal solution
The ideal solution is the solution that
maximizes the benefit and also minimizes the
total cost.
The negative-ideal solution is the solution that
minimizes the benefit and also maximizes the
total cost.
