摘　　要：[目的]固有能力是效能的重要组成部分。为开展舰船系统固有能力评估工作,[方法]以舰船系统指标体系为基础,对无法定量获取的功能指标,以系统级测试、设备BIT/外部测试点测试结果和可靠性模型,建立故障状态与功能指标的量化对应关系。结合多分类鲁棒能量模型—最小二乘双支持向量机(RELS-TSVM)方法对系统固有能力进行初步评判。[结果]仿真结果表明,所提的多分类评估模型与简单支持向量机模型相比,分类正确率提高了8.97%;通过添加系统级测试方案,提高了对系统故障的覆盖率,提升了评估结果的可信度,解决了基于数据驱动的固有能力评估方法中数据获取难度大的问题。[结论]验证了基于测试分析和RELS-TSVM的舰船系统固有能力评估方案的可行性和优势,可为武器装备效能评估研究提供新的思路。[Objectives]The inherent capacity of ship system is an important part of efficiency.In order to evaluate and research inherent capacity of ship system,[Methods]for the function indexes which are difficult to be quantized,the quantitative correspondence between fault status and the function indexes is established by the external test point test and reliability model on the basis of the index system of ship system.A multi-classed robust energy model least squares twin support vector machine(RELS-TSVM)method is used to make a preliminary evaluation for the system inherent capacity.[Results]The simulation result show that the multi-classification evaluation model proposed in this paper improves the classification accuracy by 8.97% compared with the model of simple support vector machine.With the help of added system-level test plan,the coverage ratio of system faults is improved,the credibility of evaluation results is increased,and the problem of data acquisition difficulty in data-driven inherent capacity evaluation methods is solved.[Conclusions]The feasibility and advantage of ship system inherent capacity evaluation scheme based on test analysis and RELS-TSVM are verified.This paper provides a new idea for weapon equipment efficiency evaluation and research.
