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，
) V3 g& I$ F8 q1 Z0 v  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:
7 V. W2 c7 i4 A/ v$ {4 y$ N$ f- L  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
! x* t* B' r# N; ^$ }( v  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.
$ R' y' N, d6 ?1 M! V) n  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
1 z& H7 k( t) s/ pSend 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.
; I- y4 q7 }) R- M4 Y, a$ q
问题：
! s( j/ K& z8 w& D$ n; [9 DAfter running the model for 10,000 days, what was the average number of loads in each process?

不胜感激！

begin P_A arriving
- f: |5 Z  J# ?( Q0 {. Fmove into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/
/ }, ~. ^9 [' T. `+ }0 y* m
use R_A for n 60,10 min /*Resource A*/

in P_C, you need to send to die.
