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,$ _& z, 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 |: Y; ^7 h2 U, C' _ Loads are processed by each operator for the following time:. S: {, K5 m6 H! M( M" v2 R, I
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
- r Y. V9 P" T, E 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.

* [" b) D) u! Q! r6 m& MSend 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.
