A company has several departments that conduct technical studies and prepare reports for clients. Recently, there have been long delays in having these reports copied at the company's centralized copy center because of the dramatic increase in business. !Management is considering decentralizing copy services to reduce the turnaround and provide clients with timely reports. An appropriate technique for minimizing turnaround time and the cost of providing copy services is:
- Queuing theory.
- Linear programming.
- Regression analysis.
- Game theory.
Answer(s): A
Explanation:
Two basic costs are involved in queuing waiting-line) models: I) the cost of providing service including facility costs and operating costs), and 2) the cost of idle resources waiting in line. The latter II may be a direct cost if paid employees are waiting, or an opportunity cost in the case of waiting customers. The objective of queuing theory is to minimize the total cost of the system, including both service and waiting costs, for a given rate of arrivals. This minimization occurs at the point at which cost of waiting is balanced by the cost of providing service. This company wishes to reduce the total of waiting costs turnaround time) and the cost of copy services.
