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, s" V4 n9 W% g* L 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.
( j; p) p$ \' i% t" q' V7 v Loads are processed by each operator for the following time:+ g# i$ w+ w6 f" T% f& O9 n
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
. ~! l5 {; f. t7 [* ^ 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.
+ w. Y, n: X1 Y# Y& W- g Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
) n& x( U$ P& ^6 vSend 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.) R; ^6 j! N0 Y+ J

问题:
- a! I ]( n( v% iAfter running the model for 10,000 days, what was the average number of loads in each process?
