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,& I8 s' S0 r2 p+ ^1 z( l
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.4 v1 b6 {6 u7 S4 W+ K6 U2 `
Loads are processed by each operator for the following time:
4 f7 g1 k7 w2 p! I! [/ ~& H& O Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
$ I$ ]) i" ~/ S( ? k 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.* _. o1 F9 o* ?# n/ Y9 |
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
7 t( p' @# m# tSend 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.' o+ h8 _) x+ F" [
9 z b+ v) x* d! H# @* R
问题:2 ~3 e" i8 S6 S: y! d, K5 W$ p7 [
After running the model for 10,000 days, what was the average number of loads in each process?

不胜感激! |
