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,# T6 e- O$ [/ l+ o, ^
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.2 K1 `, ~) e, p- |2 o3 ~/ H
Loads are processed by each operator for the following time:. ^ _* A9 y, U+ Z% u
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins." C a2 E/ T' d4 {
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.
- |5 T# e$ h9 [- O Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
