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,) N2 `6 _& c5 S, E# l
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.
* y. v, W8 x+ n7 K' R2 {' S Loads are processed by each operator for the following time:. W9 [% q+ k! ^# J: v
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins." I8 {2 J8 C p
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. }% f( g& j; g/ ~% }
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
