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，
; r  x3 g( Y! ~/ H, N9 t# H* x  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.
8 [" X& s- D7 K( Z4 h9 ?  f  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.
  \4 k, p% |3 }  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.
4 A% k0 U7 J, l% w: dSend 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.

begin P_A arriving
& H8 a, t' n( g, M4 \move into Q_wait /*Capacity is infinte*/
+ u/ |/ `; V& l+ f, z. Z8 W6 Qmove into Q_process /*Single capacity*/

' z9 i! Z+ v2 Z9 duse R_A for n 60,10 min /*Resource A*/

2 z# @& W; v& x, V# s: e" Y, |send to P_B
end

P_B and P_C is similar
! h9 Q( p  f" v$ X0 Etriangular 30,60,90 min
2 i& A0 U( v2 V5 F" r/ Eu 60,30 min

( C) y' C" U% t: |' \5 Q
in P_C, you need to send to die.

# d; h5 P4 }5 R7 yThen 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.
