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:
, ]6 |9 {5 N5 _3 u0 A  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
9 W; n4 v" _1 p, R  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.
4 O5 T5 f4 q# M3 M. ySend 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：
- }! x: |$ A  J" ~8 }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*/
, X: {9 S% Y! t3 e8 S" Gmove into Q_process /*Single capacity*/

use R_A for n 60,10 min /*Resource A*/

send to P_B
% w9 ]( p+ W& A9 Zend
& t+ _; x' o; U/ @( ^7 m2 k- g

in P_C, you need to send to die.
! M- k  t8 e' R
Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.
