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，
( V2 u0 \5 ~( W9 e$ N( x, G/ _  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.
- d. o4 O& c% h4 b1 h# J  Loads are processed by each operator for the following time:
: J: D% V8 k+ Y# Q6 G7 x  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
* @4 l; f: z, _9 `% }  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.
5 i6 t5 l4 V  ^4 l/ }% ]  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.

问题：
, B4 x8 O2 w9 mAfter running the model for 10,000 days, what was the average number of loads in each process?

. W* {+ Y; S9 W$ Pin 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.
