Answer1. “Operations Research is “the use of mathematical models, statistics and
algorithms to aid in decision-making. It is most often used to analyze complex real-world
systems, typically with the goal of improving or optimizing performance. It is one form of
applied mathematics.”
(1) Recognize the Problem
(2) Formulate the Problem
(3) Construct a Model
(4) Find a Solution
(5) Define the Process
(6) Implement the Solution

Essentially, the operations research process is your basic problem solving process, like the
introductory problem solving process you might encounter if you were studying (cognitive)
psychology, the art of mathematics,
Question2. a. Discuss any four applications of linear programming.
Answer2a. Four applications of linear programming are as follows:
1. Marketing applications:
 Main application of linear programming in marketing is “media selection”.
 Linear programming can be used to help marketing managers allocate a fixed
budget to various advertising media.
 The main objective is to maximize frequency and quality of exposure.
 Restrictions on the
b. An organisation produces X1 and X2 units of products R and S,
respectively. In this case, the objective function and constraints are
expressed as follows:
Maximise Z = 60X1 + 120X2
Subject to, 3X1 + 6X2 ≤ 240 Raw material constraint
2X1 + 4X2 ≤ 800 Labour hours constraint
X1, X2 ≥ 0 Non-negativity condition
Use graphical method to determine how many units of products R and S the
organisation should produce to maximise its profits.
Answer 2(b) - Here,
We have to maximise Z = 60X1 + 120X2
Subject to,

Question3.a. Explain the concept of Trans-shipment.
Answer3(a). Transhipment is the act of off-loading a container from one ship and loading it onto
anothership. Inany service operatedbyanyline there are practical restrictionsintermsof coverage
of ports..There is no shipping line that can cover all ports around the world on a single service and
therefore the services are segregated into trade lanes.
Let’s say there is a liner service that connects Durban to Far East with Singapore, Hong Kong, and
Port Kelangbeingthe portsof call on the voyage fromSouthAfricato Far East. Let’scall thisvessel A.
Let’s say that there is a shipment from
b. Solve the following transportation problem using North-west corner
method & Matrix minimum method.
Answer3(b).

4. The transportation problem given is :
The north-west corner method generates an initial allocation according to the following
Procedure:
1. Allocate the
Question4. The processing time of four jobs and five machines (in hours,
when passing is not allowed) is given in following table
a. Find an optimal sequence for the above sequencing problem.
b. Calculate minimum elapsed time & idle time for machines A, B, C, D & E.
Answer4.
The Processing time for the
Question5. Define following criteria’s used for decision making under
Uncertainty
a. Optimism (maximax or minimin) criterion
Answer 5(a).
Maximax (Optimist)
The maximax looks at the best that could happen under each action and then chooses the action
with the largest value. They assume that they will get the most possible and then they take the
action with the best case scenario. The
b. Pessimism (maximin or minimax) criterion

5. Answer5(b).
Maximin (Pessimist)
The maximin person looks at the worst that could happen under each action and then choose the
actionwiththe largestpayoff.Theyassume that the worst that can happen will, and then they take
the action with the best worst
c. Equal probabilities (Laplace) criterion
Answer5(c).
Laplace criterionisalsocalledaslawof equal probabilities criterion or criterion of rationality, since
probabilityof statesof nature are not knownitisassumedthatall statesof nature will occurin equal
probability. I.e. assign an
d. Coefficient of optimism (Hurwicz) criterion
Answer5(d).
A compromise between the maximax and maximin criteria. The decision maker is neither totally
optimistic (as the maximax
e. Regret (salvage) criterion
Answer5(e).
The minimizationof regretthatishighestwhenone decisionhasbeenmade insteadof another. In a
situation in which a decision
Question6. Explain the following:
a. Economic Order Quantity(EOQ)
Answer6(a).
Economicorderquantity(EOQ) isan equationforinventorythatdeterminesthe ideal orderquantity
a companyshouldpurchase for its inventory given a set cost of production, demand rate and other

6. variables. This is done to minimize variable inventory costs, and the formula takes into account
storage, or holding, costs, ordering
b. PERT and CPM
Answer6(b).
PERT standsfor Program EvaluationReview Technique, a methodology developed by the U.S. Navy
in the 1950s to manage the Polaris submarine missile program. A similar methodology, the Critical
Path Method (CPM) was
c. Applications of queuing models
Answer6(c).
QueueingTheoryhasawide range of applications,andthissectionisdesignedtogive an illustration
of some of these. It has been divided into 3 main sections, Traffic Flow, Scheduling and Facility
DesignandEmployee Allocation. The givenexamples are certainly not the only applications where
queuing theory can be put to good
