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,
  p+ m+ C9 @2 N- j+ E2 q% L3 S  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.: A7 q6 E2 _8 j0 G* G
  Loads are processed by each operator for the following time:  L0 a. b( Q7 X% t: i/ x
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
2 S3 k5 n& D) Y1 r& A6 t( A  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.
8 U5 H7 e1 r$ m, E7 x  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
# h- h& K9 d' D* A5 j% 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." m6 o) L9 e! s5 g
% i, e  b$ y% L3 J  ^1 w
问题:) Y. L5 K( \- s' u' J
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.
