粗系统与它的粗依赖
Rough system and its rough dependency
【摘要】 利用函数S-粗集(function singular rough sets),给出粗系统与粗依赖的概念,给出粗系统的依赖性度量;提出粗依赖的序定理,粗依赖的惯性定理和粗依赖的惯性原理;给出粗系统的粗依赖在经济系统投资预警分析中的应用.
【Abstract】 By using function S-rough sets(function singular rough sets), concepts of rough system and rough dependency are given,and rough dependency measure of rough systems is presented;then rough dependency order theorem,rough dependency inertia theorem and rough dependency inertia principle are put forward;finally,application of rough dependency with respect to rough system in economic system investment warning analysis is given.
