通过基准比较分析法、相似产品类比和德尔菲法、模型估算法和统计推断法4种方法对舰船装备可靠性、维修性和保障性指标量化适应性进行了研究分析和数据验证，提出了舰船装备顶层参数指标、单项指标和“三性”指标量化的原则。

Four methods of benchmarking analysis，Delphi method with similar products，analog estimation method and statistical inference methods were applied to analyze and confirm the adaptability of the quantitative indicators for warship equipment reliability，maintainability and supportability. The principles for constructing the top-level parameter index and the “three of quality” quantitative indicators for warship equipment were proposed.
