Question

Quizplus · Accepted Answer

The three parts of a waiting line system are arrivals or inputs, queue discipline or the waiting line itself, and the service facility. Option A is incorrect because the distribution of arrival times and service times are parts of the system, not discipline while waiting. Option B is incorrect because arrival rate, service rate, and utilization rate are all measures or characteristics of the waiting line system, but they are not the three parts. Option C is incorrect because arrival and service discipline are both part of queue discipline, not separate components. Option E mentions sequencing policy and expediting of arrivals, which are both related to queue discipline, but fails to mention the waiting line and the service facility.
