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，
; l! i0 i; O+ j. V! g4 x! A  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:
9 n, P( N, L# ?  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.
! i- A# Y1 `! G# N4 d  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
! U# S" \! t; X) n2 mSend 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.
  x( S- ?9 }' P+ ^9 M
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
move into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/

6 S0 ^0 }9 D6 K$ euse R_A for n 60,10 min /*Resource A*/
' F5 I$ q) s5 ]+ w- c  n9 h3 L* M
8 z4 g( f# I7 V6 X' }# I4 Qsend to P_B

u 60,30 min
& L$ H; g3 X3 x( ]) }; @) d3 J. W

in P_C, you need to send to die.

" v9 K8 L; X' K$ G" t2 }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.
