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,; T, Z9 ]2 z0 @& K( M
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 Z3 r( q4 i+ K5 h2 { Loads are processed by each operator for the following time:
3 {9 P& p/ E+ v7 }! ? Worker_A does the job in a normally distributed time with a mean of 60 mins and a standard dev of 10 mins.
! Z: M Z0 F2 t2 M/ x9 ~. Y' d8 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.
; s4 T, N: p6 u3 P A `, @. D0 A/ Y Worker_C does the job in a uniformly distributed time between 30 and 90 mins.! P% M Q, R* V8 t
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.
