摘　　要：以软件产品族为背景,以改善软件开发的效率和效果为目标,对面向软件产品族的软件开发与定制过程进行了研究;提出一种根据基于功能需求的功能相关性量化准则,根据软件系统功能元之间的相关程度从不相关到紧密依次分为5个等级,依次定义量化值为:0.1,0.3,0.5,0.7和0.9,进而对功能元两两之间的相关性根据功能相关性量化准则构建相关性矩阵,并运用聚类算法获得构件划分结果,实现构件提取;并分析了软件产品族构件化集成配置机制,提出了基于功能构件-业务构件映射机制的框架结构;最后结合证书管理信息系统进行实例分析.In the background of software product family, in order to improve the effectiveness and efficiency of software development, the software development method and customization procedure for software product family are researched in this paper. A quantitative criteria for functional correlation is proposed based on functional requirements. According to correlation degree between the software system functions, it can be divided into five grades from no correlation relationship to close correlation relationship. They can be defined in form of quantitative value as 0.1,0. 3,0. 5, 0.7 and 0.9. Then the correlation matrix can be set up based on the quantitative criteria of function correlation between the functions. The clustering algorithm is used to obtain the results of divided components and extract the components. Furthermore, the componentization configuration mechanism of software product family is analyzed and an architecture based on functional components-business components mapping mechanism is proposed. Finally, combining with the certificate management information system, a case is studied.
