基于解释结构模型的装备测试性影响因素分析方法

Analysis Method of Influencing Factors of Equipment Testability Based on Interpretive Structure Model

测试性是装备的一种通用质量特性,有着与可靠性、维修性、保障性一样重要的作用,通过将装备测试性影响因素之间关系进行整理和剖析,对提升武器装备的使用保障性能力、战备完整度以及减少全寿命系统损耗等都有着重要的意义;采用了德尔菲方法得出16种影响装备测试性的相关影响因素,并在此基础上引入解释结构模型(ISM),从而建立装备测试性相关影响因素的解释结构模型,以探求装备测试性各影响因素间的层次性和关联性;结果表明,装备测试性影响因素的关系结构可划分为6个层级与3个层次,运用“手段-目的分析”方法识别出影响装备测试性的5个最关键的影响因素,并通过对装备系统复杂程度、研制方技术及管理水平、研制经费、测试分系统间接口兼容性以及测试点选择合理性的分析,为提高装备测试性水平提供对策建议。

As a general quality characteristic of equipment,testability has the same important roles of reliability,maintainability and supportability.The hierarchical relationship of factors affecting the testability of equipment is clarified,which plays an important role in improving the maintenance supportability level and combat readiness of weapons and equipment and reducing the cost of whole life cycle.Delphi method is used to obtain sixteen influence factors of the equipment testability,and on this basis,an interpretive structure model(ISM)is used to build a relationship structure model of influence factor of equipment testability,so as to explore the correlation between various influencing factors of the equipment testability.The results show that the relationship structure of the factors affecting the testability of the equipment can be divided into six levels and three stages.The“means purpose analysis”method is used to identify five most critical factors affecting the testability of the equipment,which provides with the countermeasure and suggestion for improving the testability of the equipment.
