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，
* U, j7 y* |; O7 g+ r  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 i* i* \7 N! K* B7 X! s6 l: v3 {  Loads are processed by each operator for the following time:
! D& c& ?7 ?& ]# T3 F) K& ^  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.
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
+ E: v4 K: O% {, \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.
; {! \8 P4 H! ^4 I* C" l5 K
问题：

begin P_A arriving
, j/ l2 S* A* emove into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/

4 e( M6 h. c& X/ q- T. nuse R_A for n 60,10 min /*Resource A*/
! f1 K& i, g; J! a8 a4 ]8 M/ B/ L7 ^: g
send to P_B
end

P_B and P_C is similar
triangular 30,60,90 min
u 60,30 min
! B. w3 G% I1 J) o
, j" I& V$ y/ i2 Z
- s6 S8 K2 \! o3 y& {/ sin 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.


Remember to turn off the animation before you run your model.
