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,
3 P& }0 p, y/ G9 p; V  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.! a! w- S& F* _6 X7 z% ^
  Loads are processed by each operator for the following time:; N" P" F4 B/ M# N
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
5 |# @' e8 i/ ^. V) \( ?& E& q' A  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.
& m' n. e6 ?" s& p! c& K  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
" V4 L* Q. c/ q% e* k$ B1 n& d, U0 ]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.
( O+ `- |' p0 E# W! x0 }" L* K( M2 ~- L
问题:" u( ?- C9 b) M7 m2 Q, z9 z
After running the model for 10,000 days, what was the average number of loads in each process?

不胜感激!

in P_C, you need to send to die.

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