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,4 D8 @# W- K6 ~8 a& Z
  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.
  t* p. e! m6 Q, f  b% I5 Z7 G  Loads are processed by each operator for the following time:
! T$ @2 D& Y# z) R  d( Z. C8 |* Y  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.: J8 T) w; Z6 E' l, d
  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.
' p0 l9 p8 V" I5 N% W  Worker_C does the job in a uniformly distributed time between 30 and 90 mins./ Y; k, S4 ]& z$ Z
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.
& n4 m- ]; o' D; f2 G2 f4 K$ J
' m8 [3 h& U; i3 E) k" ^问题:1 G6 @0 P7 w! l: ?. r4 J) d3 X
After running the model for 10,000 days, what was the average number of loads in each process?: p2 c7 j2 j# W: \9 Q
$ b/ k, e, Y1 r9 a
不胜感激!

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.
