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，
, M9 {+ x* w: g2 m# ?  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.
$ L7 G( p( ~8 q8 F" Y2 |5 |  Loads are processed by each operator for the following time:
4 v, R9 A* ?) G+ @2 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.
  p) I9 X6 [; Y7 E) Q* w( m1 Q$ U  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
" ]) f8 A' D9 jSend 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.
9 j3 ]# }, A* M9 G9 T( A
2 M7 ^) I/ G2 h6 L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*/
7 [, Q/ ~& e& _. \$ s- Z4 i, z  pmove into Q_process /*Single capacity*/
* L% X" F! ?6 h
: m7 z7 A' _6 u1 Wuse R_A for n 60,10 min /*Resource A*/
$ L  R; l1 f7 x5 r  k* q% q
, a1 s+ h8 M0 T' i+ \, ksend to P_B
end

P_B and P_C is similar
5 z9 O( @! ^$ ktriangular 30,60,90 min
u 60,30 min

5 [; s5 k9 ]2 Z) S  g) ?
$ A# x" J, Y. }# K# E* ~' ?" \, ^5 Qin 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.
9 h' H  d+ a. _5 C2 _% A' F8 R

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