1.Explain what is meant by capacity planning and control and describe the implications of a capacity constraint in one of the micro operations of an organization of your own choice. 2.Discuss the implications of having too much or too little capacityfor the following operations: 3. Discuss with an operation’s manager the demand trends for the organization’s products or services, covering the long, medium and short terms. Find out the periods over which the manager makes or uses forecasts and the problems resulting from any inaccuracies in those forecasts. 4.Identify several ways in which the following organizations mightmeasure their capacity (discuss the relative merits of each and suggest the one you think each organization will use): 5. A car battery manufacturer makes four types of car battery: compact, compact-heavy duty, standard and standard-heavy 144
duty. Table 11.4 shows the number of batteries of each type currently produced to order for existing customers and the amount of time each battery spends with the acid-filling machine. The machine is capable of working up to 24 hours a day and needs no adjusting between battery types. The operations manager is under pressure to increase the utilization of the plant. The company has been approached by two new customers to supply batteries. Company A requires someone to supply them with between 80 and 100 batteries per day of various types. Company B requires 10 compact and 70 standard batteries a day, all heavy duty; however, delivery must be assured. Table 11.4 Battery production Number produced per day Time with acid filler (mins) Compact 80 3 Compact HD 50 5 Standard 90 4 Standard HD 20 6 Assuming the acid-filling machine is the only capacity constraint, review the merits of each order. 6.Explain how utilization might be measured in the operations following and discuss the relative merits of using utilization and efficiency as measures of operations performance: 7.What factors do you think would affect the volume, timing and types of calls coming into a call centre run by a car insurance company which advertises in newspapers and on television? 8. Which do you think will be the main capacity plans, and how might they be implemented, for the following organizations: 145
o a university o an Accident and Emergency ward at a hospital o a compact disc producer o a taxi service? (Explain the reasons for your choice.) 9. The management of an hotel on a popular Greek holiday island is concerned that its hotel is full between March and September, is about 80 per cent occupied in February, March and December and about 30 per cent occupied during the other months.
