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:
) _. Q2 h) Y; M3 a5 }  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
6 Y6 t+ x0 n2 q- R  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.
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.

9 o# n; a1 C: s- |: c' ~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*/
0 y$ z* J' T3 r' E! a! ?. F" A' Imove into Q_process /*Single capacity*/

use R_A for n 60,10 min /*Resource A*/
6 B" T* U! B( `1 F  O4 B& I% m
send to P_B
  H3 ?  O# c/ P& w! ~0 _end

4 l$ ?. n  r/ Y! m( V: X, TP_B and P_C is similar
triangular 30,60,90 min
: y$ j& V. l" [0 R" A' P  V; ~u 60,30 min
% n5 P$ O+ s( M0 B6 z8 _' S

in P_C, you need to send to die.
: D$ l6 ~% C* e  X6 q( b
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.
