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，
; y  P. R. }- I6 i4 g  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:
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
# D* l- [+ v  c' M  L) W. c& M  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.
/ B' z0 ^& M! cSend 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：
$ h+ ]. P: R" U) D7 bAfter 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*/
5 Y& ?0 f: Q4 c, qmove into Q_process /*Single capacity*/
" I6 d% G% q, f
- S5 x% P. G5 r" Ruse R_A for n 60,10 min /*Resource A*/

send to P_B
$ j. s8 y4 A* X: wend

P_B and P_C is similar
' L0 k; i& ^3 F8 atriangular 30,60,90 min
% e* }: z* \, V, uu 60,30 min


$ U  Q+ N# `2 _& E% A. yin P_C, you need to send to die.

Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.
