Research Of Rough Set Theory And Insert Taxis Based On Pansystems Topology

In order to study or generalize one problem, first, find the relativity factor of the problem, generalize the relativity factor, then use the pantransmitting of pansystems methodology, construct new model of the problem. Based on this thought, this paper does expanding research of rough set form the view of pansystems.First, by doing research of pansystem topology,according to the similarity of pansystem topology and rough set approximation,that is approaching an object form inner and outer,put forward rough set model based on pansystem topology; Decision table attribute reduction is one main content of rough set theory,this paper from the view of pansystem topology does research of decision table attribute reduction,put forward a new method for judging whether a decision table is consistent, also puts forward a new method for decision table attribute reduction.Second, based on the research of pansystems topology of Pansystems Theory, this paper defines panweighted field topology, in which we introduce semantics of element, which makes the questions even more clear.Further study on panweighted field topology, this paper puts forward rough set model based on panweighted field topology.Decision table attribute reduction is one main content of rough set theory, this paper form the view of panweighted field topology does research of decision table attribute reduction, puts forward a new method of judging whether a decision table is consistent, also puts forward a new method of decision table attribute reduction.Finally,based on the research of pansystems topology, by the upper approximation and lower approximation of pansystems topology, we contact insert taxis over linear order system. By introducing partial macro order, expend insert taxis which is true over linear order to any order, put forward a general insert arithmetic. In addition, we can construct topology by inserting.
