In a well designed waiting line system it is the variability in _____ and ______ patterns that causes waiting lines.
A) server, customer
B) poisson, exponential
C) arrival, service
D) arrival, poisson
E) service, exponential

Question

Quizplus · Accepted Answer

Waiting lines are caused by the variability in arrival and service patterns. The arrival pattern refers to the timing and frequency of customers arriving at the system, while the service pattern refers to the time it takes to serve each customer. A well-designed waiting line system takes both of these patterns into account to minimize waiting times and maximize efficiency. Poisson and exponential distributions are used to model arrival and service patterns, respectively, but the question specifically asks for the variability in these patterns, which is best represented by the arrival and service patterns themselves. Therefore, answer choices A, B, D, and E are incorrect.
