【摘要】 演化性是软件的基本特性之一。软件演化由一系列复杂的变化活动组成。本文从宏观层面入手,以软件体系结构(software architecture,SA)作为软件的蓝图和支撑,设计了复合信息矩阵模型,作为软件体系结构演化波及效应分析的新工具。结合矩阵特性、图论知识和算法设计,新模型可以对一般SA静态和动态演化中的波及图表1效应进行理论分析和量化界定,弥补了现有研究模型需要简化连接器和无法评估连接器影响的不足,从而为SA演化的利用和评价提供了更为全面的依据,并为基于矩阵变化的SA演化计算机自动处理提供了新的理论支持。更多还原

【Abstract】 Construction and evolution are two basic properties of software.Software evolution consists of a series of complex change activities.In the present paper,a multiple information matrix(MIM)model is designed to analyze the ripple-effect of software architecture(SA)evolution,based on macrostructure of SA.The novel model can display the characters for kinds of SA in the static and dynamic evolutionary process with the matrix and special algorithm.As a result,MIM can overcome the shortcoming of models in previous literature that the effect of connector cannot be analyzed.Therefore,SA can be evaluated with enough information to support the automatic computing with the new theory.更多还原
