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,) t, I5 x2 o2 @" @' h, e/ 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.
. O" t: a- i( v o Loads are processed by each operator for the following time:
7 t! q+ \, K' V( C Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
% M) b! j) }+ K8 M+ p! C 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.
" x( Z$ h- S, y8 _: j0 I Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
