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.
& j: |$ B7 q8 p. p- h  Loads are processed by each operator for the following time:
; w" _/ O! n$ n  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
. `: O6 i  ]9 Q8 i# L( A: v5 p  W  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# g' t) h4 T9 W" F  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
% J* q/ i2 K/ u4 e& KSend 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 ?+ W% \/ u. K' z0 T; R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.

Then 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.
