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," [0 h% Y: N$ w$ w
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.
, n+ o4 J* J; |, N% D: `0 r8 E Loads are processed by each operator for the following time:
: P a6 A" s& P! N Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.- k" U+ n4 L. }$ v
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.; r# D8 Z+ d9 R
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
