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,
$ x4 }' ?' w8 V; U4 m 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.
$ k7 x( S+ f# f6 U Loads are processed by each operator for the following time:
% V$ e, d: G" J+ i: Z Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins./ G7 s- T& {1 x* h
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.
6 ~. ~& O$ ?$ D5 l* H/ O& ~ Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
7 W( p; k' u* H7 ^/ XSend 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.% M5 n+ l( I; E1 _8 W5 L. [ r1 \
5 F; `3 {9 y0 o E5 V* x) }
问题:+ X* e! n' J. Z/ R3 y# {/ n4 R
After running the model for 10,000 days, what was the average number of loads in each process? k, |# V* N9 w2 h; {
- C' \7 k+ I8 e/ r4 U不胜感激! |
