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，
) Z' T. L( }6 i  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.
" V* k8 y5 Q" r  Loads are processed by each operator for the following time:
4 I8 ]$ m" p5 |3 @: v9 Y! }  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
4 j+ l& Z  |6 x/ v0 q8 @  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.
- w" |$ y" _& q! O( P. @$ d  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
+ o! u5 p. m0 j& DSend 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：
/ Q# y6 {) i" RAfter running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
$ }$ k5 O& m* [6 i+ }move into Q_wait /*Capacity is infinte*/

send to P_B

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.
