Abstract:Aimed at uncertain factors and dynamic characteristics of evaluation process, a static effectiveness evaluation method of aviation material support is put forward by establishing the pairs of effectiveness evaluation index of every unit and utilizing the Set Pair Analysis(SPA) theory that has the characteristics of ensuring same different and opposite of unsure system rational depict on certain speciality. Again a dynamic effectiveness evaluation method is proposed by utilizing the Markov chain to analyze the effectiveness evaluation change rules of aviation material support for certain unit. and then, put forwarded the dynamic effectiveness evaluation method. Example calculation shows that the synthesis SPA method can provide scientific basis for the decision maker in making the strategy of aviation material support.
