软件维护是软件生命周期的重要阶段，通过维护修改缺陷、提高性能、延长生命周期。针对维护成本难以控制的现状，运用灰色关联分析研究维护成本因素的影响程度。首先，构建影响因素指标体系递阶层次分析结构模型，并对各因素进行描述；然后，按照无量纲化处理、计算关联系数、计算关联度、关联度排序与结果分析等步骤构建数学模型；最后，以某软件公司软件维护成本的数据进行实例分析。本文的研究内容，对于改进维护过程、指导维护活动、提高软件质量、降低软件成本等方面具有重要的理论和现实意义。

Software maintenance is an important stage of software lifecycle , modify defects , improve per-formance and extend the lifecycle through by maintenance .For the current situation that the maintenance costs is difficult to control , use gray relational analysis to research the influence degree of maintain cost factors .First, build a structure model of influence factors index system hierarchical analysis , and describ; Second , build a mathematical model according the steps of dimensionless method processing , calculating the correlation coeffi-cient, calculating the correlation degree, correlation degree sort and results analysis;Finally, give a example a-nalysis with a software company software maintenance cost data .The content of this study has the important theo-retical and practical significance for improving maintenance procedures , guiding maintenance activities , impro-ving software quality and reducing software costs .
