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,
* {* b/ v0 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 \' d9 h$ s G3 `3 z Loads are processed by each operator for the following time:" B% |, C: q: }1 U0 @ G. n
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins." _9 u1 I1 E. I% N C8 i( e P
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.; r) {# b/ O9 a+ T/ w+ R) ]& l
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
1 F, E$ m- ]( P. Y9 K/ CSend 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.+ n5 x4 |! S8 u+ D: ~9 O
