电子信息系统领域需求模型复用方法

Research on reuse of domain requirement model for electronic information system

为了解决电子信息系统开发过程中领域需求模型的复用问题,结合基于本体的需求获取方法,在介绍领域需求模型构建的基础上,提出了领域需求模型的共享方法。该方法通过领域的根本体对领域不同的需求模型进行合并、关联和修正等操作。这些操作可以识别出现有领域的不同需求模型的共同和相异特征,进而构造完整和一致的新模型。为复用领域需求模型,提高系统开发的效率和质量奠定了基础。

Reuse is an important technique to improve the development of electronic information system. How to reuse domain requirement models is a problem to be solved. The construction of domain requirement models was introduced mainly and a method for sharing the models presented. A method, in light of the characteristics of requirement elicitation based on the ontology, was offered here to merge, associate, and align domain requirement models with the root domain ontology. These operations can identify the common characteristics of the requirement models as well as the different ones, and construct a complete and consistent new model. Thus, the reuse of models can be easily implemented to improve the development efficiency and quality.
