摘　　要：为实现需求演变过程管理,有效解决需求演变对系统的影响分析,通过构造定义本体来记录需求演变不同周期内的各类信息,并采用分层管理的策略,根据需求之间的依赖关系,构建了需求依赖分层树,展示需求之间的相互依赖关系,并引入代价分析方程来确定需求演变处理的优先级。这种基于本体的方法能够形成需求演变管理框架,实现对需求演变的自动管理以及对需求演变控制和需求追踪。To effectively analyze and manage the influence on software requirements evolution,an ontology was used to describe the information about requirements evolvement,and a layered tree for requirements was built according to the dependent relationship between requirements.This tree can support the layered managements of requirements and describe the dependent relationships between the requirements.A cost equation was introduced to define the priority of the requirements in the framework.Then the tree can be used for influence analysis.A framework to manage the requirements evolvement can be built based on the method,and the framework can control requirements evolution and trace the requirement changes.
