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.
  Loads are processed by each operator for the following time:
) [6 H7 f' Y9 ?; @" P  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
2 v. _3 ]) z6 n  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.
; z/ r# p$ L1 i. w3 m+ @( A$ r+ eSend 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) I! a( T* `: a# Z2 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
' ]# @! u9 O% R: o+ y6 h, O% G' w# pmove into Q_wait /*Capacity is infinte*/
$ X$ I+ ]8 }5 n, ]) f: Ymove into Q_process /*Single capacity*/
" ?4 |; Y6 C9 b$ }
use R_A for n 60,10 min /*Resource A*/

send to P_B
end

P_B and P_C is similar
triangular 30,60,90 min

Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.
