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,( F  S3 O0 f3 B2 n3 G0 J
  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.
, o* F! \  s; @2 i1 o% _- k! w  Loads are processed by each operator for the following time:
1 T6 F, w# S/ o/ H( z# t7 O: @  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.; q' O$ R+ m, x6 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./ t4 y! [3 D9 L
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.5 e( d/ y7 l- v/ \2 t) h" B: ?
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.
/ d7 R' q' m1 Y$ p. L6 O
1 E0 [' }! p. i8 I. ~4 g问题:* _1 a5 W4 c9 k: O$ B
After running the model for 10,000 days, what was the average number of loads in each process?2 v) ~( I; r9 P1 m* E

不胜感激!

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