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,# G# _" z9 t6 M+ y% X
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.
% I2 w$ n6 | F! w! S Loads are processed by each operator for the following time:" @" i' ?) r" w7 J( D t
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
: F5 y7 K# I u) R4 Z( \ 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.
