Q.1 (a) The Good and Rich Candy Company makes a variety of candies in three factories
worldwide. Its line of chocolate candies exhibits a highly seasonal demand pattern,
with peaks during the winter months (for the holiday season and Valentine?s Day)
and valleys during the summer months (when chocolate tends to melt and
customers are watching their weight). Given the following costs and quarterly
sales forecasts, determine whether (a) level production, or (b) chase demand would
more economically meet the demand for chocolate candies:
Quarter Spring Summer Fall Winter
Sales Forecast 80000 50000 120000 150000
Beginning workforce = 100 workers
Production per employee = 1000 pounds per quarter
Regular production cost per pound = Rs.2.00
Inventory carrying cost = Rs. 0.50 per pound per quarter
Firing cost = Rs. 500 per worker
Hiring cost = Rs. 100 per worker
(b) Identify several industries that have highly variable demand patterns. Explore how
they adjust capacity
04
(c) Describe the output of aggregate planning. 03
Q.2 (a) List various objectives of Scheduling. 03
(b) The Clean-Car service has five cars waiting to be washed. The time required (in
minutes) for washing is given below.
Car 1 2 3 4 5
Wash 5 7 10 8 3
In what order should the cars be processed to minimize average flow time?
04
(c) Discuss the process of vendor rating. 07
OR
(c) Discuss scheduling approach for various types of manufacturing processes. 07
Q.3 (a) List some of the operations and functions in a company that are dependent on a
forecast for product demand.
03
(b) What is the difference between quantitative forecast methods and qualitative
forecast methods?
04
(c) A computer software firm has experienced the following demand for its ?Personal
Finance? software package:
A manufacturing company has monthly demand for one of its products as follows:
Period 1 2 3 4 5 6 7 8
Demand 56 61 55 70 66 65 72 75
Develop an exponential smoothing forecast using ? = 0.40 and an adjusted
exponential smoothing forecast using ? = 0.40 and ? = 0.20. Compare the accuracy
of the two forecasts using MAD.

workstation, how many workers are required to operate the line? What is
the efficiency of the line?
b. If demand for televisions is reduced to 100 sets per 40-hour week, how
many workers will be needed to man the line? Re-balance the line and re-
calculate its efficiency.
