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,
8 V3 A- P$ z! W, m8 k. f 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.7 X. k% ?( R, w! x6 B, t1 L: X
Loads are processed by each operator for the following time:' h6 p( z, X u6 a
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.- D% C. R. T+ S! L
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.7 R; q, _7 E! d5 [( n6 U
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.* i6 b' w" g' y F) Z* s
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.1 x- [* U/ w' N4 Y: L

问题:
