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/ ^1 U# m5 R6 w  v2 P0 o  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.
# W$ H6 S# X5 U  Loads are processed by each operator for the following time:
0 C& i3 ~: J; b8 t+ G  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.+ f- v% g, B5 X; |
  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.
1 k# Z+ V, n/ B  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
: ~% o( Y" E1 u5 @- DSend 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.
) X2 h3 c% H" l# W% G1 h" a' @* a# S! Q. [$ }
问题:- T8 l/ Z) z; ~9 W7 ]3 }$ X
After running the model for 10,000 days, what was the average number of loads in each process?

in P_C, you need to send to die.  I# l! t- ?+ _1 D

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.
