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,
. p( ]+ M/ ?3 P8 X* R2 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.; ?7 U, W+ @8 n q# c
Loads are processed by each operator for the following time:
9 ~1 R' Z6 T. P; Q Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
0 Y) E& v/ N9 I& t! i 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.
2 ?: ~+ b4 f/ C5 ?( t Worker_C does the job in a uniformly distributed time between 30 and 90 mins.% p I# @+ M ?" T; U2 K1 h" e
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.
* }: u3 x& Y! X! q1 f8 ^
( g! s- ] M& r t, y+ z ~5 m问题:
' L, i+ p- J x7 B. G6 M$ U+ TAfter running the model for 10,000 days, what was the average number of loads in each process?

不胜感激! |
