Four of the most widely used waiting line models-M/M/1 or A, M/M/S or B, M/D/1 or C, and Finite population or D-all share three characteristics: Poisson arrivals, FIFO discipline, and exponential service times.

Question

Quizplus · Accepted Answer

While M/M/1 and M/M/S models assume Poisson arrivals and exponential service times, the M/D/1 model assumes deterministic service times (not exponential), and not all models necessarily use FIFO discipline or have the same assumptions regarding the population size or arrival process.
