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,
6 _! p7 I" V" D* x/ G) e 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.' ^8 N# I4 s5 e( g+ }
Loads are processed by each operator for the following time:
; T* E) }& z+ O/ G. S5 N Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.* Q6 ?; \% `9 O: T# T1 K8 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.
