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，
! L* r4 I7 a1 z3 u/ `0 H* c3 ^7 Y  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.
# X4 v/ k# {2 F7 d, R  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.
  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.
- u0 E5 v0 `) W+ b; h4 j( a  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
2 _/ v8 j6 [; }) I$ s/ S9 [# F! NSend 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.

% i: e" I7 S7 F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
$ J7 {( O* U5 Vmove into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/
, w! S  L& c3 ?5 v3 ^
use R_A for n 60,10 min /*Resource A*/
) M5 ~) @9 O9 @, C4 z
4 r! [' R2 s. z1 V( k! S$ Osend to P_B
4 i* @) e# T1 t6 W- a& [end

P_B and P_C is similar
triangular 30,60,90 min
$ a5 H" p7 x& R+ N2 V& }/ e& Ou 60,30 min


in P_C, you need to send to die.

6 S6 [9 r; N) L+ CThen 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.
