刚刚开始学auto mod,这道题目搞不明白,希望大家看看 题目是这样的,% A8 t- i( ?2 E! k, y! K
Create a new model containing three independent processes, each with one operator. In each process, loads first move into an infinite capacity waiting queue, then into a single-capacity processing queue.) @/ ]$ g0 u: H$ e' p0 D. m
Loads are processed by each operator for the following time:
! f8 O1 |$ x( w% p' d Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins./ @8 Q% {2 u% Y( }4 r
Worker_B does the job according to a triangular distribution with a min of 30 mins, most likely value of 60 mins, and a max of 90 mins.
& Z/ @% h, Q% f/ f2 i4 `/ e0 G6 m+ c) b Worker_C does the job in a uniformly distributed time between 30 and 90 mins.7 h. v l" p& B
Send loads to each pocess at the same rate (an exponentially distributed inter-arrival time with a mean of 68 mins) to understand the difference in the processing times of the three workers.! f) b% O- h0 P: ]: [, S
