基于变权模型的鱼雷综合性能评估方法

通过分析鱼雷分系统之间以及分系统和指标之间的关系，建立了具有递阶层次结构的鱼雷综合性能指标体系；利用模糊数学有关理论，提出了一种基于变权模型的鱼雷综合性能评估方法。首先对实航数据进行无量纲化处理，然后利用变权模型对由层次分析法获得的基本权重进行权重调整，并利用模糊综合方法实现鱼雷综合性能的量化评估。仿真数据验证了该方法用于鱼雷综合性能评估的可行性，为实航验收试验提供了决策依据。

A Method of Comprehensive Performance Evaluation for Torpedo Based on Variable Weight Model

Based on the analyses of the relationship among torpedo subsystems as well as the relationship between the subsystems and the tactical and technical indexes, a step-by-step layered structure of torpedo＇s comprehensive perform- ance indexes system is established. Making use of fuzzy theory, a method of comprehensive performance for torpedo based on the variable weight model is proposed. Firstly, sea trial data are nondimensionalized. And then the basic weight obtained by the analytic hierarchy process （AHP） is adjusted through the variable weight model. The quantitative assessment of torpedo＇s comprehensive performance is achieved by using fuzzy theory. Simulation data analysis verifies the feasibility of the proposed method, and provides a reference for the acceptance sea trial.
