INTRODUCTION

Analytical heirarchy process is a structured technique for organizing and analysing complex

decisions, based on mathematics and psychology. It is designed for situations in which ideas,

feelings, and emotions affecting the decision process are quantified to provide a numeric

scale for prioritizing the alternatives. Decision Making involves setting priorities and the

AHP is the methodology for doing that.

Rather than prescribing a "correct" decision, the AHP helps decision makers find one that

best suits their goal and their understanding of the problem. It provides a comprehensive and

rational framework for structuring a decision problem, for representing and quantifying its

elements, for relating those elements to overall goals, and for evaluating alternative solutions.

Users of the AHP first decompose their decision problem into a hierarchy of more easily

comprehended sub-problems, each of which can be analyzed independently. The elements of

the hierarchy can relate to any aspect of the decision problem—tangible or intangible,

carefully measured or roughly estimated, well or poorly understood—anything at all that

applies to the decision at hand.

Once the hierarchy is built, the decision makers systematically evaluate its various elements

by comparing them to one another two at a time, with respect to their impact on an element

above them in the hierarchy. In making the comparisons, the decision makers can use

concrete data about the elements, but they typically use their judgments about the elements'

relative meaning and importance. It is the essence of the AHP that human judgments, and not

just the underlying information, can be used in performing the evaluations.

Page 3: Analytic hierarchy process (AHP)

The AHP converts these evaluations to numerical values that can be processed and compared

over the entire range of the problem. A numerical weight or priority is derived for each

element of the hierarchy, allowing diverse and often incommensurable elements to be

compared to one another in a rational and consistent way. This capability distinguishes the

AHP from other decision making techniques.

In the final step of the process, numerical priorities are calculated for each of the decision

alternatives. These numbers represent the alternatives' relative ability to achieve the decision

goal, so they allow a straightforward consideration of the various courses of action.

USES AND APPLICATION

The Analytic Hierarchy Process (AHP) is most useful where teams of people are working on

complex problems, especially those with high stakes, involving human perceptions and

judgments, whose resolutions have long-term repercussions.[3] It has unique advantages

when important elements of the decision are difficult to quantify or compare, or where

communication among team members is impeded by their different specializations,

terminologies, or perspectives.

Decision situations to which the AHP can be applied include:

Choice – The selection of one alternative from a given set of alternatives, usually

where there are multiple decision criteria involved.

Ranking – Putting a set of alternatives in order from most to least desirable

Prioritization – Determining the relative merit of members of a set of alternatives, as

opposed to selecting a single one or merely ranking them

Resource allocation – Apportioning resources among a set of alternatives

Benchmarking – Comparing the processes in one's own organization with those of

other best-of-breed organizations

Quality management – Dealing with the multidimensional aspects of quality and

quality improvement

Conflict resolution – Settling disputes between parties with apparently incompatible

goals or positions

RANKING OF SONGS

In our case we have to rank the selected songs according to our preferences.

Objective : Choose the best song among the selected five

Criteria:

Alternatives:

Since five criteria (N) have been chosen for selecting the best song hence there will be six

(N+1) pairwise matrix comparisons. The following are the six matrices:

Pairwise comparison of criteria (Cr)

Pairwise comparison of songs for Lyrics (Lr)

Pairwise comparison of songs for Music (M)

Pairwise comparison of songs for Singer (S)

Pairwise comparison of songs for Location (L)

Pairwise comparison of songs for Actor (A)

In order to find out the best song analytical hierarchy process has been used. The three main

methods used for decision making i.e finding out the weights are:

Eigen value method

Iteration method

Linear programming method

The scale used for pairwise comparison is a nine point scale the detail of which is as follows:

1 Equally preferred

2 Equally to Moderately preferred

3 Moderately preferred

4 Moderately to Strongly preferred

5 Strongly preferred

6 Strongly to Very Strongly preferred

7 Very Strongly preferred

8 Very strongly to Extremely preferred

9 Extremely preferred

2. PAIRWISE MATRIX EVALUATION

Since there are six matrices for which weightage is to be found out hence two matrices have

been solved by using each method. The different methods used for different matrices are –

1. Eigen Value Method

a. Pairwise comparison of criteria (Cr)

b. Pairwise comparison of songs for Location (D)

2. Iteration Method

a. Pairwise comparison of songs for lyrics (L)

b. Pairwise comparison of songs for music (M)

3. Linear Programming Method

a. Pairwise comparison of songs for singer (S)

b. Pairwise comparison of songs for costume (C)

Finally after obtaining the weightages of the criteria matrix and the alternatives for each

criterion, the final rankings of the songs can be found out as follows -

Criteria Weightages Rankings

Songs [ ] × [ ] = [ ]

Let us analyse the six above mentioned matrixes with the help of three methods.

A. Eigen Value Method

Let A = [aij] be the pairwise comparison matrix and w be the Eigen vector i.e. the weights for

each criteria or song. Mostly the consistency of A does not hold for the pairwise comparison

matrices entered by us and hence we find out λmax (slightly greater than n) and find out the

weightages by dividing Axw by λmax.

B. Iteration Method

Let A = [aij] be the pairwise comparison matrix. Calculate A2 and find the row sum. The row

sums are then normalised which forms the weights of the criteria or alternatives. We further

square the obtained pairwise matrix, find the row sum and normalise them to obtain the

weights. We will continue to do this until the weights obtained in two subsequent steps are

similar up to 4 digits (or more if more accuracy is desired). This normalised matrix then

corresponds to the weights of the criteria or the alternatives.

C. Linear Programming Method

Let A = [aij] be the pairwise comparison matrix. We can obtain the weights of the criteria or

alternatives by converting the comparison matrix into an Linear Programming problem. The

objective function of the LP problem then becomes –

Objective Function: ∑ ∑ 𝑍ij𝑛𝑗=𝑖+1

𝑛−1𝑖=1

Constraints:

Xi – Xj – Yij = ln aij (i)

Zij – Yij >= 0 (ii)

Zij – Yji >= 0 for i ≠ j (iii)

Xi – Xj >= 0 i, j = 1,2,3 … n ∀ aij > 1 (iv)

Xi – Xj >= 0 i, j = 1,2,3 … . n for all k ∀ aik ≥ ajk (v)

X1 = 0 (vi)

After obtaining the values of the decision variables the weights of the criteria or alternatives can be

found out. The weights are the antilog of Xi.

FABRICS AND FALL FASHION

PART - 1

Our main objective function is to maximize profits. For this we have to find the optimal

number of units which we can sell for each product.

Given the price of Raw material and Labour and Machinery cost we can find the profit per

unit sold for each item as selling price of items are given. This calculation is done above.

In the Given question we have three type of constraints, one is upper limit of material to be

used, second is the maximum production according to the demand and third is minimum no.

of production.

Hence keeping in mind we have formed our Objective Function and constraints below.

PART - 2

Now if the Constraint is given that the Velvet material could not be returned back then whole of velvet

material available should be used.

We can see in the above solution that the Velvet shirts are produced to the maximum limit but velvet

shirts are not being produced in order to maximize the profit.

Hence in the above constraints we shall change only one constraint: Velvet Material Constraints:

3x7+1.5x10=20000

In above constraint we have removed the less than (<) condition as we now have to use the whole

material.

As by fully utilizing the Velvet She is gaining lesser profit hence she should not change her change her

decision and stick to the first plan of production. The balance material she can keep with herself.
