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,
& z) b( }9 T* o/ ?' L7 p3 s 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.) {1 g% [" G' C6 Y& R: P. M
Loads are processed by each operator for the following time:
! E c3 L% i r4 T3 z! Z* G Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.% k( i9 G$ C: l4 S
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.
. p% \; e6 `) v Worker_C does the job in a uniformly distributed time between 30 and 90 mins.0 |" l4 g# Q# [' V9 |, ^0 Q
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.
% F! B/ w# X0 s2 e: f( J5 E5 J W$ G O+ ^* l
问题:
7 z/ k) ~; @. f8 ~* S; s& |After running the model for 10,000 days, what was the average number of loads in each process?

不胜感激! |
