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,
) e, W8 @" v+ x4 W7 i 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.
) F z6 _; F* q, u: N" W Loads are processed by each operator for the following time:* T' Y1 T7 a0 `8 p. `
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins. @8 {- A& z$ D- A
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.
0 x8 x$ z' o) E+ b/ h" ^ Worker_C does the job in a uniformly distributed time between 30 and 90 mins.+ D0 i9 l* U) ~/ g" f
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.; f1 ?2 E, z# i& Z" S* B, c2 A2 \
9 Q: Q" s2 p* E* e4 p$ \问题:/ e# |1 M% p) B8 i
After running the model for 10,000 days, what was the average number of loads in each process?
0 h$ F% w0 s1 z0 H8 u% f
- k* ~! o5 T, t0 d5 V不胜感激! |
