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，
  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.
, e$ n4 @  ]" g7 x$ q; b( F# s  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.
& i' }. y/ z; h4 I8 w  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.
: g- l& U1 h  b+ P- {# a# o  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
/ u6 ]5 d; G+ a# [, ]1 x" aSend 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 F) f7 u2 l/ j. J/ |' Y3 I2 [/ o

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*/
5 d3 C; ^' a& [8 d' k8 nmove into Q_process /*Single capacity*/
- J; V, i) J; ^$ W- I: a6 ^
use R_A for n 60,10 min /*Resource A*/
7 W) U* B8 h, h1 j, L! Z
send to P_B
end

P_B and P_C is similar
+ Z5 a" ^! W" gtriangular 30,60,90 min
u 60,30 min
3 w7 d# t; K& j

in P_C, you need to send to die.
$ D& d: j0 J5 A
# W# L3 k% ^4 m! a. A5 T# ?Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.
