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,
' h9 X! }, D( w( m* O* ]5 ] 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.
% m G N' _" q* ^# \$ ]& v+ l Loads are processed by each operator for the following time:4 ~8 D8 _. O4 U8 T# u; X
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
$ P* K/ {* [' y1 m 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.: v- i2 t8 R# ?1 m: _+ S
Worker_C does the job in a uniformly distributed time between 30 and 90 mins.
3 B+ n0 r I3 Y! CSend 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.
