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，
+ a4 ^# I% I5 a  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.
5 w0 E) y) m, q/ i6 M% S  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.
# @) |' N2 z1 |! p3 m  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.
, [: t+ X0 \; ]. B- g1 u2 p  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
1 Z8 @0 }: _* i# ~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.
0 ^) g9 A4 a( z, Y) C, ~8 t
. K' o1 Y' ?/ V* J( z问题：
( j& Q1 q: n* K3 w& sAfter running the model for 10,000 days, what was the average number of loads in each process?

不胜感激！

begin P_A arriving
move into Q_wait /*Capacity is infinte*/
move into Q_process /*Single capacity*/

use R_A for n 60,10 min /*Resource A*/
& n- K, b: {/ A- X4 S5 l
send to P_B
end

- n+ F8 p+ @5 b. s, n# IP_B and P_C is similar

# S# a: a$ Z/ ]
in P_C, you need to send to die.

! `+ F! f' n/ o. P& XThen You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.


: z! o8 w) H7 a# N5 Y9 FRemember to turn off the animation before you run your model.
