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，
6 Z  r% z2 _% Y9 j8 x( U) T- @  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.
  Loads are processed by each operator for the following time:
$ j5 `6 S) M. [2 z1 l  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
' r4 J; l. S2 m5 f3 j1 K  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.
7 q0 a* p$ v. b- C6 G# q  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
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.
& h0 Z/ N% j* C  b2 y
问题：
# h: X5 d. j+ b$ XAfter running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving

in P_C, you need to send to die.

' V( ?+ H  p  t3 WThen You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.


9 U1 T, o; G1 BRemember to turn off the animation before you run your model.
