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,
8 S* y# T; ~- N3 M3 f" N, \  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.
" j1 b# w9 Q9 k6 ?  Loads are processed by each operator for the following time:7 U4 U- |# H$ J; m) C+ e' Z
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.0 H9 B2 K4 d( N  I& w8 X$ l0 Q
  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.
3 A, L/ U8 C2 s4 D  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.. k) F) A8 S  o
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.) f4 W) N2 a- s) N. E1 J8 D' D* {- Y
