SOME PROPERTIES OF THE INDISCERNIBILITY RELATION IN ROUGH SETS

The concept of Rough sets was first introduced by Pawlak in 1981. Because this theory is very important and useful in many fields, e. g. in the information systems and the man-machine systems, many scholars both at home and abroad have studied it and obtained a lot of results. Now the theory of Rough sets is still progressing rapidly. However, when this theory is applied to describing an information system, the indiscernibility

Some Considerations about Fuzzy Logic Based Decision Making by Autonomous Intelligent Actor

The article presents an approach toward an implementation of a fuzzy logic-based decision-making process by Autonomous Intelligent Actor (AIA) (© A. Tserkovny), when an input information is defined for its “strategic targeting” by a human operator in terms of a fuzzy incident geometry, whereas its “tactical” behavior (a navigation in space) is directed by fuzzy conditional inference rules. For implementing both elements of AIA decision-making a fuzzy logic [1] for formal geometric reasoning with extended objects is used. This fuzzy logic based fuzzification of axioms of an incidence geometry and a predicate apparatus [2] for AIA space orientation are also presented. The approach, offered in the article, extends predicates of a counter positioning of two objects and their mutual navigation into their fuzzy counterparts. The latter allows AIA to make certain “tactical” decisions.
