From the aspects of research meaning,the characteristics,the collection and management of combat damage data,combce damage research methods,and combat damage model research,this paper analyses the present situation and development trend of materiel combat damage research systematically and detailedly.

This paper introduces a systematic method of equipment battle damage research,based on the achievements of weapon and radar battle damage research.

The battle damage simulation method was presented, meanwhile the disadvantage of equivalent target expression was demonstrated.

This paper gives a primary analysis on data of battle damage about a gun,with the application of fuzzy synthetic judgment.

The weapon system battle damage assessment is a multi-index, multi-layer evaluation issue,there are many indexes that may influence the damage state of missile equipments,and they also have great uncertainty,there are not any evaluation methods are capable of analyzing complicated factors existing in it.

the content and characteristics of missile equipment damage assessment based on real cases is pointed out,the quantitative criterion of battle damage assessment and the definition of damage rate is also given out;a method of the co sinus vector included angle is taken to determine the damage rate of missile equipment s elements and quantitative values of vehicle.

Aiming at the diversity,uncertainty and illegibility of battle damage assessment(BDA) data sources,based on the merit of fuzzy set theory which can convert the crisp variable to discrete variable and the Bayesian networks have advantages on deal with uncertainty inference,the battle damage assessment method based on the fuzzy Bayesian networks(FBN) was brought out.

It is very difficult to get the battle damage probability of weapon equipment,and full-scale test is complex in organization and has expensive cost.
