基于决定的软件需求工程模型的设计与实现

Designing and Realization About Decision Based Software Requirements Engineering Model

需求工程是软件工程生命周期的初始阶段，其最终结果是软件需求规约。本文对需求工程的有关内容进行了剖析，设计了一个基于决定的软件需求工程模型ＤＢＳＲＥＭ，并给出了该模型的实现框架。ＤＢＳＲＥＭ的运作需要知识环境、方法工具和实现技术的支持。

Requirements engineering is the first step in software engineering life cycle,and its final results are software requirements specification.Some contents of requirements Engineering are analysed in this paper.A decision based software requirements engineering model is designed,and DBSREM frame is proposed.DBSREM execution requirs the supports of knowledge environment,method implements,realization technology.These researches have some refrence value to develop decision based software engineering.
