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.
9 H0 @) j% V, _5 P  Loads are processed by each operator for the following time:
+ I2 A" ~# B! o! @# q1 q5 k  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.
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
& c; |& U8 g% `2 Z/ eSend 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.
1 o5 d3 I% R8 T* W, _  U- [
3 U. q! v+ X  e/ W+ m问题：
After running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
move into Q_wait /*Capacity is infinte*/
& k; s; T2 F) e* H1 d6 zmove into Q_process /*Single capacity*/
8 U: R. C  @' G7 _5 S1 W

$ K) u) ]& ^8 o6 ~; j! `
send to P_B

P_B and P_C is similar
triangular 30,60,90 min

/ b2 u0 k! k9 m! `# C7 i( o. U4 Min 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.
