Closeness Degree Formula Of Fuzzy Number And Its Application

This paper focuses on the fuzzy number of close degree formula. Researching theapplication by discussionding the fuzzy close degree definition. Proposeing thetriangular fuzzy number by the close degreee concept, deduceing the close degreeformula, and then gets squence of a new kind of fuzzy number ranking method. Thismethod is not contrary to the real natural sequence relations, but better than commonranking method comparison. This paper also made in the application of linearprogramming on the basis of the method, defineing the fuzzy linear programmingconcept, the use of the optimal solution before the conclusion and method, anddiscussing a single target fuzzy linear programming solution; And then developing tomulti-objective fuzzy linear programming problem and giving the correspondingsolution. Finally, have improved the hamming formula in the paper. Defining a newclose degree formula, this formula not only has strong applicability, but also can solvemany previously formula can’t solve the problem. In the application of patternrecognition, other close degree formula compared with the improved hamming formulahas a strong resolution.
