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,
' T- k5 v7 _0 M: w2 }5 m9 r* 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.
/ w5 Z4 Q' h) F9 p5 y  Loads are processed by each operator for the following time:
! [% x0 A, V6 t0 J, o2 k8 {  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins., l7 B+ @$ j9 W& w+ \' B  G5 |" v: N
  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.& I# N. A5 v& b5 F* ^3 c
  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.6 \& a, D1 f/ T) o' H* Y6 v2 ]# D. x
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.

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