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,2 P3 r  ^& s1 F+ D  U
  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.8 P4 B3 f% c9 g7 X! l
  Loads are processed by each operator for the following time:9 s  [4 l& V" _! Y+ y9 n% Y0 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 A- \  q; n' o; Y/ Q# n. h, V  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., y' G4 b9 K; j2 ?
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.+ }# V% H( Z4 J; F& [
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.
4 j9 p9 P  \7 m
0 k- H4 z# e( a' [5 @( f问题:, ]9 Z5 [0 V% F
After running the model for 10,000 days, what was the average number of loads in each process?# |( a) c: e/ c8 M: X; i
1 @6 g/ Q, v# Z! j" D5 G$ c8 q
不胜感激!

Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.% R- Z  l- e) H% m' b. [4 p& `1 ], u( G

Remember to turn off the animation before you run your model.
