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,
( M! N' o  [# \# B" e2 Y  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.: O, o  h- k, W$ w; c
  Loads are processed by each operator for the following time:
5 J0 O: s4 ~) `  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
4 h# k6 j& p) e: t1 X  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.
$ b% _; L+ g, t) M' y( l! A  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
. w! K% Y* {  Z" wSend 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.1 F' W. O# M5 B' X! F: P, Q

" F, \% w# U& ~+ x3 f" h问题:1 N) r& L9 q; K" [! A8 Y; u$ H: _  t
After running the model for 10,000 days, what was the average number of loads in each process?. e2 p- ?2 M& c, l

不胜感激!

Remember to turn off the animation before you run your model.
