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,4 y) T0 [% h% h1 a
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 j+ x# k3 I. C# d o I# H
Loads are processed by each operator for the following time: l4 g8 K0 L; m5 F' H6 L# M+ H
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins./ N r. d- [9 {" _- U2 m
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.
9 C+ T8 _- N1 {5 u* A7 w( ] Worker_C does the job in a uniformly distributed time between 30 and 90 mins.6 h6 D9 h" P8 R0 X& x8 {& O
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., k. Y# F& ?$ H1 p: ]4 `5 V
( c* I Z. J- h. V3 p问题:; i" |6 @3 U' \! n' _' h
After running the model for 10,000 days, what was the average number of loads in each process?
