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，
6 d& X2 `4 ~5 J  R1 Z5 `6 q  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:
+ i8 V/ P! ?9 Z+ }) d9 x+ C( y  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
0 O7 [# ^, C0 Q; l$ N  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.
! o6 k4 z: p% A( x+ ^1 j  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
8 B& f3 m7 T" _1 _: a/ ^% 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.
  \  [% l; w9 k4 w8 ~

begin P_A arriving
/ {4 S. I! N4 f! H1 Dmove into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/

use R_A for n 60,10 min /*Resource A*/
, N$ ~) H' A* f  \1 I9 A! y
send to P_B

9 a8 {# `9 @, v- ctriangular 30,60,90 min
& p. z; P: C+ n4 qu 60,30 min


in P_C, you need to send to die.
9 e  k: `) s8 X8 E7 F' b" j5 \2 t
Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.
