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,
$ K* L4 _, W+ p$ } 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.4 m, w) T" Y; [* ^/ k5 ~# o
Loads are processed by each operator for the following time:
8 Q9 a u% [$ q7 a b% _( h/ k# I Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.9 R) v$ m; W, G5 l* I5 I9 `" L% m( `4 L
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.9 M5 s# d3 L! w0 b/ Z: _
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.6 x' y& [2 Z8 p8 ]
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.
