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,
1 v$ H [3 p6 F! b" b' w 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.
# S; J0 Q* R3 }, W$ M. D8 A1 D( I Loads are processed by each operator for the following time:" k& n0 V0 F6 q& q- ~8 R
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
4 G1 {2 z/ m# s- w& J 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.5 p# F, a% K: X* Z
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.* k0 K2 q$ y* x' p1 R& T
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.0 _ p5 |4 G# v h
2 ` S4 b' s" [$ j) W
问题:% L3 d l7 K$ Q- Z- J; N2 X
After running the model for 10,000 days, what was the average number of loads in each process?

不胜感激! |
