摘　　要：维护是软件生命周期的一个重要阶段。软件的可维护性是构成软件质量的一个重要方面,直接决定了在软件系统或产品上需要投入 多大的成本与精力。当前,软件的可维护性越来越得到业界的重视,并逐渐成为衡量软件系统或产品是否成功的一个重要标志。人们对于软 件可维护性的分析与研究的热情也越来越高,期望能找到软件系统可维护性提高和优化的方法。从理论而言,研究能够从组成软件生命周期 的各个阶段入手,文章着眼于软件设计阶段,从软件设计的角度对软件的可维护性的提高与优化进行分析探讨.并针对一个具体项目给出相 关解决方案。Maintenance is an important phase of software lifecycle. Software maintainability is a key aspect of quality to software, which directly impact how much effort and cost will be spent on related systems or productions. Currently, it has become an essential point to evaluate whether a software system or productions is successful. People pay more and more sight on the software maintainability and give consistent analysis and research and try to figure out how to improve the software system maintainability. Answer can be extracted from each phase which composes the whole software lifecycle. This article focuses on the impact to maintainability from software design sight, and gives out a solution on improvement and optimizes on the software maintainability.

关 键 词：可维护性 改善 软件设计
