摘　　要：软件和软件开发过程的复杂性决定了软件可维护性所涉及的数据具有不确定性和模糊性,为了提高软件的可维护性,研究改进软件可维护性的策略,基于粗糙集理论,提出了一种软件可维护性特性因子分析模型。该模型建立了可维护性分析系统,给出了两个特性因子相关系数和系统分辨矩阵的定义及计算方法,提供了一种通过分析特性指标关系,研究改进可维护性的策略的方法,有助于软件组织发现管理的薄弱环节,改进过程。Complexity of software and software development process determines the involved software maintainability data with uncertainty and ambiguity. In order to improve the software maintainability and study improvement strategies for software maintainability, this paper proposed software maintainability characteristics factor analysis model based on rough set theory. The model establishes maintainability a-nalysis system and presents the definition and calculation method of the correlation coefficient of two char-acteristics factors and system discernable matrix. The model provides a method studying improvement strategies for maintainability by analyzing the relationship of characteristics factors. It can help software organization find the management weaknesses and improve process.
