基于模型法应对企业信息系统工程中不确定性需求

Dealing with uncertain requirements in enterprise information system engineering using model-based approach

在软件工程或具体的需求工程中,用户需求通常具有不确定性。这成为了企业信息化实践中的主要问题之一;在企业信息系统工程中这尤其是一关键问题。通过扩展模型的概念、分析企业领域中可用模型的情况,提出了一种基于模型来应对用户需求之不确定性的方法。描述了应用基于模型的方法确定企业信息系统需求的基本逻辑与主要活动过程,并给出了一个应用ARIS(集成信息系统结构)参考模型库解决需求问题的实例。研究表明,基于模型的方法可用于有效地应对企业信息系统工程中的不确定性需求。

In software engineering or specifically in requirements engineering（RE）, users＇ requirements frequently appear to be uncertainty and thus that has become one of the main concerns in ente rprise informationisation practices. This is particularly a key issue for enterprise information system engineering. Upon expanding the model base and analysing the current situation of domain models, a modelbased approach is proposed to address the uncertainty of users＇ requirements. The basic logic and activity-based procedure for such a method of addressing users＇ requirements are described. A project example is given, in which the ARIS （architecture of integrated information systems） reference models are employed to clarify users＇ requirements. The research suggests that the model-based approach is used to efficiently deal with uncertain requirements in enterprise information system engineering.
