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,. [) p4 A5 S: H8 s
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.
6 r3 G: b! `! u& n- W# X, ~- ~' y Loads are processed by each operator for the following time:5 G' C# f; I( P7 Y6 s
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.5 n2 o% g' r: S$ m; K
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.
