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.
  p0 ^6 [/ ~! J/ k& C  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.
2 f) b: q% ^1 U8 [0 s2 \" R% ^; 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.
1 b2 t5 w& b$ i- }* _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.

问题：
' q: ^, f9 K5 PAfter 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
move into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/
  b; f0 w$ h. y0 W& x: Y
3 F% k6 `6 r4 L) H4 I! Wuse R_A for n 60,10 min /*Resource A*/
! i% x8 j; k, }
/ w  ], }: U  G+ S% ]; L* Ssend to P_B
7 Q( [, k! z9 O+ }7 S1 Vend

P_B and P_C is similar
, S$ g6 d/ U- Utriangular 30,60,90 min
" ~# c, {5 Z  q4 D; X5 O4 g* su 60,30 min
, z/ L' h5 T( @3 M& o- a7 m

in P_C, you need to send to die.
; e1 z( M8 d  @/ p
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.
