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,2 B) A8 o- A( w7 s0 Z
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 O* E$ s: o$ N: p$ t6 [
Loads are processed by each operator for the following time:
7 m# C* t0 n: P) S+ ` G+ k$ L Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
+ q+ f3 M. F* ~ ?3 h! I 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.
