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,
/ n1 i8 ^1 {" i$ \+ X 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 M0 o7 t# U s/ T
Loads are processed by each operator for the following time:; ^; y. c6 v5 g- ?+ |, v3 q
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
$ a4 C5 X2 K7 H4 K+ v' ~ 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. o$ ~3 s# f z- p
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.4 S. ~; m, q4 h% j7 a$ f$ @
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.
