Answer: In organisations, managers are required to make judicious use of scarce resources,
such as men, materials, machines and capital, to minimise costs and maximise profits. A
technique that is used to select the best alternative from a set of feasible ones in situations
where the

a. Discuss the concept of unbalanced transportation problem
b. Find the optimum transportation cost in following table
D1 D2 D3 D4 SUPPLY
S1 3 1 7 4 300
S2 2 6 5 9 400
S3 8 3 3 2 500
DEMAND 250 350 400 200
 Unbalanced transportation problem
 Optimum allocation.
 Optimum transportation cost
Answer:
Unbalanced transportation problem:
When the total supply of all the sources is not equal to the total demand of all destinations,
the problem is an unbalanced transportation problem.
Total

b. What are different Practical applications of simulation
A Meaning of Simulation.
Practical applications of simulation
Answer: a) Simulation is a representation of real-life situations. It is a method in which a replica
of a real-world process or system is developed over a period of time. The simulated model acts

1 a. Define the meaning of assignment problem in operation Research.
b. A Departmental head has four subordinates and four task to be performed. The
subordinates differ in efficiency and the tasks differ in their intrinsic difficulty. His
estimate ofthe times each man would take to perform each task is given in the following
matrix-

How should the tasks be allocated to subordinates to minimize the total man-hours?
A Description of assignment problem
Optimum allocation through Hungarian method
Answer: a) An assignment problem is a special type of transportation problem. In an
assignment problem, the
2. Define following criteria’s used for decision making under Uncertainty
a. Optimism (maximax or minimin) criterion
b. Pessimism (maximin or minimax) criterion
c. Equal probabilities (Laplace) criterion
d. Coefficient of optimism (Hurwicz) criterion
e. Regret (salvage) criterion
Answer: a) Optimism (maximax or minimin) criterion: Here, the decision maker tries to
achieve the largest possible profit (Maximax) or minimum possible cost (minimin). If the entries
in the payoff matrix are the one which the decision maker wants as large as possible, for
example, profits or sales revenue, he/she selects the alternative that represents the maximum of
the maximum payoff. In

3. Answer: a) In an organisation, replacement problems arise when fixed assets, such as machines,
equipment, and other tools, need to be replaced due to reduced efficiency, failure or breakdown.
Sometimes, replacement takes place when more efficient equipment is available in the market
or the maintenance of the existing equipment is incurring a huge cost on an organisation.
However, an
