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，
' b4 }# H/ b  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.
; x# e' Q( H( l2 b& }  Loads are processed by each operator for the following time:
0 @8 V, a& v8 T2 b( q, @0 F* f' p  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.
# K8 M; t7 [9 e6 @9 J: p8 g  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.

问题：
6 Z$ M3 M" r, q8 KAfter 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*/
- i$ ?$ P2 Q, Z
use R_A for n 60,10 min /*Resource A*/

- a  H$ J  M0 M6 n; ]7 zsend to P_B
end
) ^  s. }+ O! m  ^% O
P_B and P_C is similar
triangular 30,60,90 min
: j+ ~; F: R. ru 60,30 min


2 G+ Z' z' S# w2 S! L4 Hin 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.
