Q1. Write short notes on:
a. Origin of operations research
b. Levels of Strategies in an
Organisation
c. Consumer Pricing Expectations Range
Answer. a. Origin of operations
research
Operations
research as a discipline originated in Britain during World War II. At that
time, the military forces were having very limited resources and they were
forced to allocate those scarce resources in an effective manner. To deal with
this problem, the British military management hired a number of scientists and
asked them to perform research on military operations. The scientists developed
several effective methods for using radar and managing convoy and
anti-submarine operations. Using these methods, the military forces were able
to win the Air Battle of
Q2. Explain following Models of
Operations Research
a. Iconic model
b. Analogue model
c. Symbolic model
d. Descriptive model
Answer. a. Iconic model: This model is an exact representation of a particular
entity. It includes various diagrams, graphs, and charts that aid a manager in
the decision-making process. This model can be full-scale, scaled-down or
scaled-up in size, as discussed below:
Ø A full-scale model refers to a working model,
for example, a model of sawmill, which shows the moving sawmill.
Ø Scaled-down models are used to represent
bigger objects, such as buildings and highways. These models are the small
picture of big objects so that they can be easily seen.
Q3. Case Study: Services Operations
Management at XYZ Restaurant
XYZ restaurant has been performing
satisfactorily over the last 30 years. It opened its first outlet in the year
1980 in Pune, and since then it has grown to 1000 outlets in the mid-east Asia.
In the year 2000, XYZ restaurant enjoyed the maximum footfall in almost all the
nations it was present. By 2005, it added Italian and French food in its menu
to compete with the established international brands in this field. XYZ
followed a process of service operations management, which focuses on
delivering excellent services to the customers.
After some time, XYZ faced a problem
of low quality of French and Italian food that was not at par with other
restaurants. The nations of mid-east Asia did not welcome the change in the image
of XYZ from local food chain restaurant to international restaurant. The
customers found lower quality of French and Italian foods in XYZ than they used
to get in other restaurants. The offering, delivery and image of XYZ could not
match the new services and customers avoided to visit XYZ for Italian and
French foods. The market of this restaurant was still favouring its local sense
of cooking food. XYZ soon reverted to the earlier service operations and
policies of local belongingness and thus recovered the lost customers.
Discussion questions:
1. What can be the reasons for the
failure of XYZ restaurant in introducing French and Italian foods?
2. What strategies could have helped
XYZ restaurant while introducing new services?
1.
What can be the reasons for the failure of XYZ restaurant in introducing French
and Italian foods? (Hint: The reasons can be failure of making planning
activities, monitoring and controlling activities and quality assurance
activities)
2.
What strategies could have helped XYZ restaurant while introducing new
services? (Hint: Following SERVQUAL and evaluating the performance of services)
Answer. 1. Service operations management can be defined
as a process that focuses on delivering excellent services to the customers.
Other definitions are as follows:
Ø Service operations management ensures that the
attention is given to the correct functional service delivery areas.
Ø Service operations management refers to a
process that focuses on the design and management of systems for services.
Q4. Explain the following criterions
that a decision maker may adopt under uncertain conditions.
a. Maximax Criterion
b. Maximin Criterion
c. Minimax Regret Criterion
d. Realism Criterion
e. Insufficient Reason Criterion
Answer. a. Maximax Criterion: It is the criterion in which a decision maker
selects the alternative that provides the maximum payoff. This criterion is
based on the assumption that all available alternatives would provide the best
possible outcome. Maximax criterion is a strategy that maximises the maximum
gain. The maximax criterion is also known as the optimistic criterion or rule
of optimism. Following are the steps under the maximax criterion:

Also determine the total assignment
cost.
Optimal
assignment total assignment cost
Answer. Conduct row and column operations as the
assignment problem is balanced. The row operations involve selecting an element
having a minimum value in each row starting from row A and subtracting that
element from all other elements in that row. After completing row
Q6. There are four jobs, namely D, E,
F, and G, which need to be sequenced on two machines, namely machine 1 and
machine 2. The processing time of the jobs D, E, F, and G on machine 1 are 2,
6, 4, and 8, respectively. However, on machine 2, the processing time of D, E,
F, and G is 3, 5, 7, and 4, respectively. Determine the job sequencing for this
problem and Total flow time for four jobs.
Optimum
Sequence - 5
Total
flow time - 5
Answer. The steps involved in solving
the preceding sequencing problem are as follows:
1. Prepare a table that contains the processing
time of the four jobs on the two machines, as shown in Table below:
