Active equipment improvement is based on the foundation of the primary product, by the diversified measures of improvement, the tactics performance and structure of the product received partial improvement, to obain the aim of enhancing or improving equipment performance and extending the use-lifetime. Active equipment improvement is a complicated system engineering process,the restrict factors, technical difficulty and the risk are unavoidable. To ensure the improvement task go on wheels, so the risk analysis and evaluation are necessarily developing on time, and adopts the pertinent measures keep away in advance. Research on the active equipment imrovement risk factors was conducted, the risk evaluation index system was established and the structure entropy theory was applied to evaluate the sequence of the index system and the comparatively optimum scheme was put forard. Finally, the factor analysis method was applied to analyze the index system, which confirmed the rationality of the index system.%现役装备改进是在原有产品基础上,通过采用各种改进措施,对产品的战术技术性能和结构进行局部改善,以达到提高或改进装备性能,延长装备使用寿命的目的.现役装备改进是一个复杂的系统工程过程,制约因素多、技术难度大,风险在所难免.为确保改进任务顺利进行,必须及时开展风险分析和评价研究,从而预先采取针对性措施加以防范.研究分析了现役装备改进的风险因子,构建了风险评价指标体系,并运用结构熵理论对指标体系的结构有序度进行了评价,提出了相对优化方案.最后,运用因子分析方法(FA)对构建的指标体系进行了因子分析,验证了指标体系的合理性.
