本人初学auto mod,有一道题目希望大家赐教

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，
  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.
4 d5 K' E6 E8 o) P% ]! @. l  Loads are processed by each operator for the following time:
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
8 b& q$ z; h, N4 h' {6 I  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.
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
$ s5 y' R) ?7 D& ^8 OSend 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 z: G1 n; o, _% S; ~8 K# `问题：
After running the model for 10,000 days, what was the average number of loads in each process?

in P_C, you need to send to die.

# J3 `: G; L0 vThen You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.

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