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,
/ @8 l" p8 S( \# a$ R) H 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.
6 Q+ T) h) s9 H Loads are processed by each operator for the following time:
, _. H/ y3 ?. x+ d2 @6 H* P Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
3 d: B& l" ?4 R: q0 V, t 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.4 d0 z, W7 \/ w
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.2 p/ X* x9 n4 s; }6 {
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.
* G. w; B+ @; @8 N: o2 H1 H$ {: z6 z2 g7 _8 ~! `* z' ?, S' f
问题:
