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,% p8 Y' a2 M& g; N2 {; \ V
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 ~, K! _; u& y0 Q& \5 L/ B Loads are processed by each operator for the following time:- M/ X% j* k5 j+ P4 P+ J5 q K. D
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.' M* j7 @0 c3 ~0 V4 N
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.

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.! n) X& r* Z; f4 ~
