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,
' f6 Y* v* {! O' b  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./ v$ K, I, x7 X+ _; z' Y7 ?) w
  Loads are processed by each operator for the following time:
1 N7 h: r* n* m! T9 x( z/ B  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
4 T: f* M& c$ {: t9 P  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.% c. u- I& t) k! K9 v/ L7 |' x8 b
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.% K, M5 ?+ `5 e* W( H$ O+ m1 {
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.

问题:

不胜感激!

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.: Y# q. c6 R- e1 s- V. I, V

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