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.
- C1 U6 f( }0 e7 i" o9 t/ I1 [  Loads are processed by each operator for the following time:
7 s* p+ |7 U5 B! l) d$ n  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
  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.
2 C  ^0 g1 o  J4 |9 V- h  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
( b  a5 n! S4 E3 K+ f0 aSend 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.
( J# s4 K: ?! t) n  i. z2 k. V2 l+ a
( ?, v( `+ l* S) Q- l; x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.
