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.
3 c- [8 r- [! a' b' Q* s  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.
) y3 K* P2 q' ]% f  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.
8 O% N" C+ ]6 g  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.
4 f/ n! Y  j% c, X. z
问题：
  ~& B' E* z1 b  E* V+ [/ fAfter 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*/
move into Q_process /*Single capacity*/

$ s. ]% {' X- D1 Muse R_A for n 60,10 min /*Resource A*/

2 i1 s/ |0 u- W- Ksend to P_B
5 H9 h+ W- U  B+ V+ dend

& r2 q" g/ ?( J- k- m, J& k) o, yP_B and P_C is similar
triangular 30,60,90 min
; g$ S  S6 P  A' O, M3 Eu 60,30 min


in P_C, you need to send to die.
5 Y/ L3 j( _0 j$ `
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.
