软件维护性迭代验证方法

Software Maintainability Iterative Verification

基于软件维护性尽早、全过程迭代验证的思想,提出了贯穿软件生命周期的维护性迭代验证策略及过程,建立了基于功能块平均维护时间的维护性迭代验证模型。通过阶段性地开展软件维护性验证,可及时发现软件维护性设计缺陷并及早更改,避免造成严重的维护性质量问题,大大降低软件使用阶段的维护费用,提高软件系统的完好率。通过制定规范的软件维护性验证策略和方案,规范了软件维护性验证实施过程,为软件维护性验证人员提供了可行的操作指南,也为软件维护性验证平台开发人员明确平台需要提供参考。实例验证结果表明:所提出的软件维护性迭代验证方法是有效、可行的,可为软件研制人员提供理论指导,也为软件使用和维护人员制订软件维护计划、配置软件维护资源提供决策依据。

According to the principle of the whole process iterative and earlier verification of software ma-intainability,iterative verification scheme and process through all software development is made and mod-el of maintainability iterative verification based on mean maintenance time of functional modules is built. Through episodically verification of software maintainability,software design defect can be found in time and be removed as fast as possible,so as to avoid serious quality problem on software maintainability, greatly reduce the maintainance cost of software in use and improve and readiness rate.Through making standard software maintainability verification scheme and plan,the software maintainability verifying process can be standardized,and software prototype system designer and developer can be guided.A real software case is exemplified to demonstrate that the methods above are feasible and effective,which can be used to guide software designers and developers theoretically and provide decision-making basis for software users and maintainers to make software plan and allocate maintainance resources.
