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,- l* W1 j% O2 ^7 e+ w; M& }
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.
1 |* @1 E7 k0 R- } Loads are processed by each operator for the following time:

Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
