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, b! t' F! a# g0 [, q
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.
) [. Y! E4 c, n Loads are processed by each operator for the following time:: x1 r. e" _8 Q s! O
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.6 t2 h3 z! V& r& s) Z
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.5 @! h: V5 _$ Q4 h( R9 A9 R, T) ~
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
$ M6 ]. W7 O; ~8 ]Send loads to each pocess at the same rate (an exponentially distributed inter-arrival time with a mean of 68 mins) to understand the difference in the processing times of the three workers.
