Conceptual Design Scheme Evaluation with Grey Relation Projection for Combat Aircraft
LI Shou-an · Flight Dynamics · 2007
Evaluation indexes of the conceptual design scheme for combat aircraft are analyzed,the weight coefficients of every evaluation index are determined with the Analytic Hierarchy Process,and a conceptual design scheme evaluation method for combat aircraft based on the Grey Relation Projection method is proposed.The method builds a weighted grey relation matrix of the evaluation indexes for aircraft conceptual design schemes with grey relation theory,then calculates grey relation projection values of the design schemes on the perfect scheme by vector projection theory,the design schemes can be evaluated by the grey relation projection values.
