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.
- W6 q+ H$ L$ _3 l5 |9 f7 O0 s  Loads are processed by each operator for the following time:
8 A+ }- D* n9 K4 ~8 Q! D; K1 O  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
* U  u3 @7 y' H, K8 k) K, V  ~  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.
; @5 O5 A3 p: Q! R$ E/ j
问题：
After 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
( E- s8 l& c% kmove into Q_wait /*Capacity is infinte*/
; a$ j5 [+ t4 a6 ]  j* N+ \move into Q_process /*Single capacity*/
) c& C) |6 ~1 d$ d9 n$ j
use R_A for n 60,10 min /*Resource A*/

send to P_B
% C# l/ q* N$ T% |; M3 Rend
. l0 O, I6 z! N4 i" O! v8 _2 u) }! p
P_B and P_C is similar

# W% r2 ?% E7 z3 Sin P_C, you need to send to die.

& z, T4 }! s. e3 U$ E$ @0 BThen 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.
