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,
6 _! p7 I" V" D* x/ G) e  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.' ^8 N# I4 s5 e( g+ }
  Loads are processed by each operator for the following time:
; T* E) }& z+ O/ G. S5 N  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.* Q6 ?; \% `9 O: T# T1 K8 p
  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.
! t% e8 l# a6 n0 N2 K  D& R  }9 C8 `  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
! w! L% y! W: X+ C9 L5 H; V0 vSend 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.

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