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, i/ _; w/ m2 ~( ?0 G
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.
7 I q6 r4 @; E( C. N: U2 k9 \ Loads are processed by each operator for the following time:: F7 [7 N2 d: F% f
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
8 ]( `: t- P% \8 y 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.
