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.
3 M( U1 G7 R8 `7 a- _  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.
" b5 Z0 K0 K. t5 y9 l; K% L1 ~  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.
0 z0 A' A$ k3 R5 M0 i  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
, I3 u1 {, l7 m) s- ]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.
$ ?' w1 D. f0 [% B: _1 d. y
问题：
# N+ j2 d# C( m3 z4 @After running the model for 10,000 days, what was the average number of loads in each process?

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.
