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,
/ h+ t7 R& v4 U, c- U9 v7 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.
( M" ^/ W4 K2 K) {) h2 C  Loads are processed by each operator for the following time:( p' ?0 l8 ]; |) J
  Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
' t" `! R9 j3 r1 \8 c5 v* X4 w( f  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.
' L0 p$ B6 @7 g' t' `" I8 @  Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
3 i% N1 h( [6 u7 z& q! LSend 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.
