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，
& h; F, q8 C( A2 b" D" ^  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.
0 n* u2 x7 t$ l" P' t# M% 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.
" c9 ]% M3 U/ H4 E) b/ G  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.
" l/ ?" k( R4 ?$ ^$ ^6 F5 HSend 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.
  f: n$ [1 O# Z3 B) ^$ G
问题：
, l- }$ N/ {  f' U' }0 \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*/
move into Q_process /*Single capacity*/

9 P" S3 S2 z9 U" I; W6 W2 Xuse R_A for n 60,10 min /*Resource A*/

send to P_B
end

P_B and P_C is similar
triangular 30,60,90 min
& M; N" S8 Y/ W" o3 x! s' f  tu 60,30 min
5 B2 R: p' L5 D5 H% A+ \

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.


) f+ S- ?6 D; O$ i8 JRemember to turn off the animation before you run your model.
