Document Summary

The major cost trade-off is between the cost of waiting for service versus the cost of providing additional service capacity: what assumptions are necessary to employ the exact formula: Inter-arrival times are exponentially distributed (i. e. , poisson arrivals), which implies a purely random arrival process, but with a know arrival rate. Service times have cvp = 1 (e. g. , mean = standard deviation). In a bank, fcfs may be perceived to be unfair by customers who have large accounts. In a hospital, especially in an emergency room, fcfs is probably the exception rather than the rule. Fcfs would be unfair when a patient with a minor problem is treated before another experiencing severe pain: define, in a practical sense, what is meant by an exponential service time. An exponential service time means that most of the time, the service requirements are of short time duration, but there are occasional long ones.
