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，
( ^! b( |; ~- ^0 f  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:
: e. Z: K( P' j# W# A: ^6 u  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
3 o! z" {* i  k/ R$ H  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.
: T+ [' m8 D5 ]* v  c  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
- |: |$ X$ {, lSend 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.

! p/ j+ _6 c3 d% s5 o) N/ K问题：
After 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
8 N. \- z$ X5 B% ]* Jmove into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/

9 o% R7 f5 `) `6 ouse R_A for n 60,10 min /*Resource A*/
! n) G2 v! Y1 X# M2 g9 i2 I
send to P_B
end

P_B and P_C is similar
triangular 30,60,90 min
1 m/ {2 ]: w, K) Su 60,30 min
9 B- T; Z8 G3 o" j# o

7 u: B; p# y) P$ \in 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.
0 ?6 d5 X( v. u2 L- g0 W

Remember to turn off the animation before you run your model.
