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,& \6 ]9 a  c4 D( _. k
  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 v+ D# n9 v, l  Loads are processed by each operator for the following time:& g! Z1 x3 b( h6 q( d
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
) _) \- a% i% B1 c  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.6 K9 N" a5 T- [/ K- v; q9 I
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.8 ^* P" Z, d" d& x
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.6 c) `( r2 x+ |- p- Z
* R2 W0 M  Y" s2 u; n; [6 n! t$ H
问题:
  t# u0 [) Q2 j8 o% H' T7 p  R/ gAfter running the model for 10,000 days, what was the average number of loads in each process?' l9 J8 w  ?# ]# g/ ^
