The prognostics and health management(PHM) system is now playing an important role in promoting transition of the operational aircraft from run-to-failure,scheduled preventive maintenance to condition-based maintenance.

The good organized dispatch supportability in the wartime can effectively keep sortie generation of operational aircraft and enhances the whole combat capability of combat troops.

The logarithm model in fighter plane air-to-surface target attacking effectiveness assessment is analyzed firstly, and its faults are put forward.

We present an effectiveness evaluation method for fighter plane by using theory of multiple objective decision making.

Overview of research on military aircraft combat effectiveness analysis;

For the improvement of the aircraft’s executing ability,the effective factors of the military aircraft’s executing ability was introduced in this paper,and the assessment parameter for the executing ability of the military was illustrated in the case of training and combating.

It is important to establish military aircraft scheme evaluation index set.

Research on the index systems for conceptual/preliminary design comprehensive evaluation of combat aircraft;

Quantitative Evaluation Model for Combat Aircraft Operational Effectiveness

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.

It is applied in the sensitive device,display,thermodynamic power control,communication of the military tactics airplane to navigate system control etc.
