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,9 a8 G# H& [$ B) u C4 U& h( J+ 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.
8 W4 }4 d. s) j( y9 h6 W Loads are processed by each operator for the following time:1 X$ a4 _6 X! c- \
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
