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，
2 J6 W9 F+ Q6 q* W1 U  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:
  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.
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
$ N; ?, [$ P' L( x7 ^3 h' \3 S8 XSend 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.
5 H& J- J# Z, g) y6 {% K- ~' ^. y3 {
问题：
After running the model for 10,000 days, what was the average number of loads in each process?

begin P_A arriving
move into Q_wait /*Capacity is infinte*/
: v# M: O. l8 n% wmove into Q_process /*Single capacity*/

use R_A for n 60,10 min /*Resource A*/
% t+ I5 m/ L, `$ u$ M, W3 I; K3 G
# ^* T1 i( y8 P( t' Q# gsend to P_B
- @' A" ]) X( Q$ O  u4 P& h4 \end
/ D- c. W6 w& B$ m4 @: u
P_B and P_C is similar
# x# C( t) `* `& h# H. E, x* w+ v3 ztriangular 30,60,90 min
u 60,30 min


+ P$ k9 l( j8 X  [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.


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