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,
( c8 `9 A! p8 D 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.% a- L( {5 D0 c, v
Loads are processed by each operator for the following time:
9 R* @8 d% B" ?: E5 k0 |- l/ d Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.( o ~2 O5 m; P2 m
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.
5 B2 H8 x" B! I Worker_C does the job in a uniformly distributed time between 30 and 90 mins.5 ?% z6 x- g/ y. h. u
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.7 P0 h- R" U( C: H. f+ n* L3 {
