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，
: A3 r. C7 ]9 V5 \% w! A4 _  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.
1 e3 S! E5 v& s( Z  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.
7 A; Q* o' V3 Z) H# ~  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.
1 h$ ]3 B2 J% kSend 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.

3 Z" V' o& A; Y. u( }1 K问题：
After 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*/
/ Q# o1 z2 G; `2 D# O$ Cmove into Q_process /*Single capacity*/
$ a( Z. Y' d/ I; B
use R_A for n 60,10 min /*Resource A*/
+ C( a& N4 X  b) O
send to P_B

! Q0 i4 p3 F! ]! B' A! T- W  @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.
