Efficiency Evaluation Model Based on Belief Rule Base with Insufficient Data

National defense is very important since it has great influence on the stabilization of a nation and the welfare of its people. To accomplish the mission and tasks of national defense, the weapon systems need to be in its best conditions and be most effective. However, it is rather difficult to directly construct an effectiveness evaluation model from a national defense level since there are multiple influential factors that are interacted and can not be analytically integrated in one single function. Moreover, there are insufficient data which makes it more difficult for the modeling and training approaches. The Armored System of Systems (ASoS) is used as the combatant background. Moreover, the belief Rule Base (BRB) expert system with a training approach is applied to construct the effectiveness model. The proposed approach is validated by a Missile Armored System of System (M-ASoS) case study.
