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,
% {$ y; r/ |3 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.2 U/ x* U# e8 o) ?6 Z; [
Loads are processed by each operator for the following time:6 ^# p! Y2 J5 o! p" E. s! n0 U
Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
& f4 P/ h$ B- k" O7 N( D 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.
; W# q- H8 C. L Worker_C does the job in a uniformly distributed time between 30 and 90 mins.4 M( t( s6 m: S2 N4 h+ ^+ y, z8 B8 |
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.
