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,; Y2 f3 P9 j3 {$ j( n3 T
  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.+ e1 M# j. @# H/ x
  Loads are processed by each operator for the following time:8 S, k3 x7 D8 g2 f( z) T
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
; T# n2 J' L- e! F/ K$ b: U  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.4 m, p$ t" ~' x# f
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
/ U0 y' M+ ]$ p* x8 @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.$ t, s9 V' T  k( M+ D2 N. C; P

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.
