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,7 F% E: _& F" ]- o, q
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.0 @) U+ w% j0 [/ I+ L
Loads are processed by each operator for the following time:% ]% \, W0 d5 N9 {/ j& p& I% v
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
6 k: {4 n8 j& ^! 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.

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.# X( B4 G r/ Y% p6 [
