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，
* p1 u' x- n/ @  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:
9 G  T/ _& ?" p$ b' g) ~9 @, f9 }4 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.
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
; A& g6 {' h9 x3 Z( v. }* gSend 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.
# F' I3 n( C- E* U, \1 x* x" h! h: r" I
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*/
8 S6 w9 e, c; Y+ I: Bmove into Q_process /*Single capacity*/

$ x; h# c1 E5 E' Buse R_A for n 60,10 min /*Resource A*/

# E6 y- M+ E4 |% @' }& b7 Nsend to P_B
end

P_B and P_C is similar
triangular 30,60,90 min
. h) G" I! T, Wu 60,30 min


; _  q& m# @, a) {% Zin P_C, you need to send to die.
) Q; L0 m  ^% ^
Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.
