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 e9 A) d# \, B6 u
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.2 f2 O8 l0 Q* R1 k7 T( e) f- ]0 Z
Loads are processed by each operator for the following time:
2 _$ I! F4 f% r$ o5 {9 c2 O" t Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.. d7 R2 r8 P) E: s4 i) O% a
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.
% G. _5 ?( k+ {3 Z/ W$ D Worker_C does the job in a uniformly distributed time between 30 and 90 mins.0 D) ^% } i, o& O
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.3 R5 U) j9 e+ {: [& I5 @
