In this paper, the terminal air defense equipment system of systems (TADESoS) is studied as an example. The TADESoS is an important part of the joint air defense equipment system of systems, which mainly carries out the combat task to the low altitude flight target. The contribution rate evaluation of the TADESoS can provide theoretical basis for guiding the tactical plan of the TADESoS. Aiming at the problems existing in the evaluation of contribution rate of TADESoS, such as the difficulty of describing the structure of system of systems, the strong subjectivity of the evaluation method, and the difficulty of application of the evaluation results, this paper proposes a method of evaluating the contribution rate of the TADESoS based on fault tree. The method describes the structure of the TADESoS by multiattribute nodes. The probability of the top event is calculated by using the probability of the bottom event. Finally, based on the importance of the bottom event, the contribution rate evaluation model of the TADESoS is established, which solves the existing problems in the current research. Finally, the feasibility of the method is verified by an example.

基于故障树的系统设备系统贡献率评价方法

本文以终端防空装备系统系统（TADESoS）为例进行研究。TADESoS是系统联合防空装备系统的重要组成部分，主要对低空飞行目标执行作战任务。TADESoS的贡献率评估可以为指导TADESoS的战术规划提供理论依据。针对TADESoS贡献率评价中存在的系统结构难以描述、评价方法主观性强、评价结果应用困难等问题，提出了一种方法基于故障树评估TADESoS贡献率的方法 该方法通过多属性节点描述了 TADESoS 的结构。顶事件的概率是通过底事件的概率来计算的。最后，基于底部事件的重要性，建立了TADESoS的贡献率评价模型，解决了目前研究中存在的问题。最后通过算例验证了该方法的可行性。
