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,; r; g- d. T" Q0 q) Z
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.! G9 W; c* H6 z; C
Loads are processed by each operator for the following time:2 y" a( W: W% i- r6 A; V
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
$ }# k" i! K) p- 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.
