中文摘要：

软件重用可有效地降低软件开发过程中的成本并提高开发资源的利用效率，本文在价值链的形式化概念与元模型的基础上，通过对面向重用的软件开发过程与传统开发过程的特征比较，对面向开发过程的软件开发价值链进行了定义，该价值链在重用已有软件资产的基础上将开发过程中的不同环节、角色和活动进行了系统的集成，通过建立软件开发过程价值增值矩阵和度量指标体系，对软件开发过程中的增值活动进行了定量化的分析，并证明了面向重用的软件开发过程具有更高的价值增值．

英文摘要：

A formalized definition and a meta-model about value chain were introduced for analysis the difference between traditional software development process and reuse-based process. Furthermore, some metrics in software development value chain was proposed and compared in value matrix. The results show that the Reuse-based development process has more value improvement than traditional software process, which collaborated all the resources and roles in software process together under an open environment.
