PROGRAM MBADS/ MBAFLEX/ MBAHCSN3/ MBAN2/ PGDBAN2
SEMESTER II
SUBJECT CODE & NAME MB0048 OPERATIONS RESEARCH
Q1. Discuss the various stages involved in the
methodology of Operations Research. Briefly explain the techniques and tools of
Operations Research.
(Operations Research
Methodology-5, Techniques and tools of Operations Research-5) 10 marks
Answer.
Operations Research Methodology
The first and the most
important step in the OR approach of problem solving is to define the problem.
One needs to ensure that the problem is identified properly because this
problem statement will indicate the following three major aspects:
Q2. Explain the steps
involved in linear programming problem formulation. Discuss in brief the
advantages of linear programming.
(Steps involved in LPP-4, Example-3 Advantages
of LPP-3) 10 marks
Answer.
Steps of formulating
Linear Programming Problem (LPP)
The following steps
are involved to formulate LPP :
Step 1 : Identify the
decision variables of the problem.
Q3. a. What is degeneracy in transportation
problem? How it can be resolved?
b. Solve the following transportation problem using Vogel’s approximation
method.
(Degeneracy
in transportation problem and resolving it-5, Computation/Solution to the
problem-5) 10 marks
Answer.
a.)
Degeneracy in transportation problem
A basic solution to an
m-origin, n destination transportation problem can have at the most m+n-1
positive basic variables (non-zero), otherwise the basic solution degenerates.
It follows that whenever the number of basic cells is less than m + n – 1, the
transportation problem is a degenerate one. The degeneracy can develop in two
ways:
Case 1 - The
degeneracy develops while determining an initial assignment via any one of the
initial assignment methods

Q4. a. Explain the steps in Hungarian method.
Differentiate between Transportation and Assignment problem.
b. Find the optimal assignment of four job jobs and
four machines when the cost of assignment is given by the following table:
(Steps
in Hungarian method-3, Differences between Transportation and Assignment
problem-3, Computation/Solution to the problem-4) 10 marks
Answer.
a.)
Hungarian Method Algorithm
Hungarian method
algorithm is based on the concept of opportunity cost and is more efficient in
solving assignment problems. The following steps are adopted to solve an AP
using the Hungarian method algorithm.
Step 1: Prepare row
ruled matrix by selecting the minimum values for each row and subtract it from
the other elements of the row.
Q5. Define
Simulation. Explain the Simulation procedure. Discuss the use of Simulation with
an example.
(Meaning of Simulation-2,
Simulation procedure-4, Use of simulation with an example-4) 10 marks
Answer.
Simulation
Simulation is the
process of defining a model of a real system and conducting experiments with
this model for the purpose of understanding the behavior (within the limits
imposed by a criterion or a set of criteria) for the operation of a system.
Using simulation, an analyst can introduce the constants and variables related
to the problem, set up the possible courses of action and establish criteria
which act as measures of effectiveness.
Q6
Explain the
following:
a. Integer programming model
b. PERT and CPM
c. Operating Characteristics of a Queuing System
(Explanation of
