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.
  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.
  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.
* B7 i3 q  o' C2 p" Y  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.
7 n! d! ?$ n) ?* d
问题：
After running the model for 10,000 days, what was the average number of loads in each process?
* b7 h, ?2 R) i- {! \8 q+ T
不胜感激！

begin P_A arriving
move into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/
7 T0 P/ S( c! n+ C1 y. |7 e2 n
use R_A for n 60,10 min /*Resource A*/
( a' u3 u" {# X, }
send to P_B
3 Q: s3 t+ Q) @% O2 kend

P_B and P_C is similar
triangular 30,60,90 min
( [$ T! @# t* V+ [1 Z4 ~8 G+ N$ Qu 60,30 min


in P_C, you need to send to die.
) G- i4 T( N) N& T" w3 S
4 E( y, Z/ T, U+ \, eThen 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.
