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，
7 w  Q3 [8 ?8 n2 T6 L  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.
! F4 u' Y9 b( o4 Z6 [& B/ k8 x1 ~# e  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.
- t9 Q' l  e) I/ S# I  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.
+ X) W+ |7 Y$ ?4 A2 c2 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.

begin P_A arriving
# `0 Y' ?1 V3 O6 Z6 T& Dmove into Q_wait /*Capacity is infinte*/
3 Y# n. T6 F) ^7 zmove into Q_process /*Single capacity*/
6 \) h4 G( j$ |! t* ]3 `
use R_A for n 60,10 min /*Resource A*/

send to P_B

P_B and P_C is similar

; D8 f5 F3 q; ]/ F6 }in 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.
