基于演化构件模型的软件演化研究

Research on software evolvement based on evolved component

基于CBD,从软件演化的角度提出了演化构件的概念模型、技术模型以及演化构件关系运算的相关理论,建立了演化构件关系图到演化构件关系运算表达式的转换算法,为用代数理论研究构件的属性、行为特征以及软件演化提供了理论基础和依据。系统地分析了软件演化过程中的波及效应及构件贡献度,为控制软件演化过程、制定合理的演化方案提供了技术支持。

Based on CBD and from the point of the software evolvement, the conceptual and technical model of evolved component and the relative theories of relation operations between evolved component were proposed in this paper. The transitional algorithm from relation diagram to expressions of relation operation was established, it provides theoretical bases for the research on attributes and behavior characters of component and software evolvement. The influences and degree of contribution of components during the evolving procedure of software were systematically analyzed, it provides the technical supports for the controlling of procedure of software evolvement and making rational evolving schema.
