Quantitative Analysis for Management, 13/e

Summary

Waiting lines and service systems are important parts of the business world. In this chapter, we describe several common queuing situations and present mathematical models for analyzing waiting lines following certain assumptions. Those assumptions are that (1) arrivals come from an infinite or very large population, (2) arrivals are Poisson distributed, (3) arrivals are treated on a FIFO basis and do not balk or renege, (4) service times follow the negative exponential distribution or are constant, and (5) the average service rate is faster than the average arrival rate.

The models illustrated in this chapter are for single-channel, single-phase and multichannel, single-phase problems. After a series of operating characteristics is computed, ...
