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，
' ?8 S. ?7 k$ T+ Y8 \, @1 w/ Z+ C* C$ T, c  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.
& k% }7 `! f. T8 J1 y2 L" p$ l  Loads are processed by each operator for the following time:
/ `9 L9 _; h6 G+ K% z- X% {; o  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.
$ f" u$ u& t) a: s5 A  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
Send 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.
; M6 W% |" o  H) k
问题：
After running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
4 V* l7 b+ w0 D7 omove into Q_wait /*Capacity is infinte*/
6 Z+ U. E! F/ G( d& w) P3 amove into Q_process /*Single capacity*/

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

send to P_B
( E! Z7 W* Y# ]& y' R  Jend
9 G' r* a9 n9 R9 s1 T
P_B and P_C is similar
0 y0 N# F) w* b& j7 htriangular 30,60,90 min
u 60,30 min
8 B) U, ^# v. e, O# {; o

in P_C, you need to send to die.
9 S) U( P/ H6 z1 B8 S6 ~
( ^- b, t$ M8 ?; GThen 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.
