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,
" D% l  W4 U1 b1 ^0 J3 X  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 y) f  T1 D4 D2 y3 j+ I) H/ L
  Loads are processed by each operator for the following time:7 D7 x3 l7 p- \, {2 i2 r
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.7 F( E& y7 q! X  ]8 e
  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.5 e0 s( `$ |& s0 V4 B3 T
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins." K" d* e) i$ N4 E+ ?: ?
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.
( y6 v' ?% _: y6 u$ S# E
- S% d& V6 ^6 Y' N8 h3 I问题:6 U8 L* k2 r% l2 J$ G) e# X! c
After running the model for 10,000 days, what was the average number of loads in each process?

Then You need to add a L_Control to drive up the whole simulation. and a Run Control of 10000 days.

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