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,
$ y, {4 H) D4 Y8 M9 S( ~2 v4 R 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.
- T+ s$ E; N8 `8 z9 j+ } Loads are processed by each operator for the following time:
8 `$ g. p& D5 W1 R# Y, d Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
- R4 e9 _/ |& C g& \3 A3 X 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.# U5 ^0 ^& s; K: r
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.7 A: C2 R6 E, t" X) V
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.
