The Research Of Rough Management Decision

Rough management decision is the management dicision that consider α-equivalent class [x] as the managing object, which exists in almost all management systems, but does not cause enough attention. In fact the management decision people usually faced regards singular element x as the management object. Regarding a -equivalent class [x] (generally card{[x]) > 1) as the management object is the meanings of "roughness" and the difference to common decision. Because of so many merits of rough management decision, it has attracted people's attention and research interest. In this paper we present rough management decision, one direction S-rough management decision, two direction S-rough management decision and give its model and analysis based on common management decision and Z.Palwak rough sets(R_X,R^- (X)), one direction S-rough sets ((R,F)XX°),(R,F)°(X°)), two direction S-rough set ((R,(?))。(X^(?)),(R,(?))° (X^(?))), where (?) = F∪F|-,F≠φ,F|≠φ;F,F|- are separately the element transfers. And then present the transfer characteristic of S-rough management decision, the heredity characteristic and heredity theorem of S-rough management decision, with which we set up the theoretical frame of rough management decision. In fact, if we consider α -element equivalent class [x] as element x, then the rough management decision changes into common management decision. So the common management decision is a special case of rough management decision and rough management decision is the general form of common management decision.The central results of this paper are as follows:...
