Abstract: An expression of correlating parameter is developed whichcan be used to synthetically express the close combat maneuverability offighters by the method of fuzzy mathematics. On the basis of analysisof fighter maneuvering performances, this paper proposes the parame-ters。，and SEP to measure the maneuvering performances. Thelinear weighted method, which is one of the basic methods of transfo-rming several objects to a single object in mathematical programming, isused to determine the form of the correlating parameter expression.The focal point of this paper work is to determine the weight coefficientsof maneuvering performances in the expression. In order to solve thisproblem, the inverse problem of synthetic judgment in fuzzy mathematicsis employed. The development of the equation of fuzzy relationship inthis paper is based on the judgment data, which are gathered from manye::perts working in aeronautical field. Therefore, the expression of co-rrelating parameter developed by this paper can be used in the desigaobject in aircraft conceptual design stage and the judgement of synthe-tical measurement of the maneuverability of fighters.
