Research And Application On Dynamic Fuzzy Dependent Relation Of Data

"Dynamic and fuzzy" exists universally in the objective world and the subjectiveness world, and is an unavoidable problem of great complexity. The research about the dynamic fuzzy data has been brought highly to some expert' s attention,and has gained some initial results. Based on the dynamic fuzzy sets, this paper studies the dynamic fuzzy dependent relation of data, and the theory of dynamic fuzzy dependent relation has been put forward, and applied in the library user' s evaluation . By the way of designing "the library user' s evaluation system based on the dynamic fuzzy dependent relation ", the research of theory has been practiced, and affords a operable application system for the library. These works combine dynamic with fuzzy of the data in the studies, and have gained clear effect. In conclusion, this paper has gained following results:( 1 ) The basic concept of the dynamic fuzzy dependent relation has been put forward, and the definition, quality , algorithm of the dynamic fuzzy dependent relation has been given out.( 2 ) The means of uniformization of the dynamic fuzzy dependent relation has been put forward, and the simplification method of the complicated dynamic fuzzy dependent relation has been found.( 3 ) "The library user's evaluation system" has been designed and realized, which applies the theory of the dynamic fuzzy dependent relation to practice.( 4 ) "The relation analysis evaluation" in the library user's evaluation has been put forward, which further enrichs and develops "the weighted average evaluation" .(5) The successful application of the system has afforded an advantaged platform for the library, and the system can afford decision-making.In summary, these works of this paper have a stimulative effect to thetheory of dynamic fuzzy relation, but there are many problems need to be studied further, such as "dynamic fuzzy clustering dependent relation" , and so on .
