数字化工程中面向系统重用的信息提取

Information extraction in digital project for system reusability

摘要:

系统重用技术作为数字化工程的一部分，具有减少重复劳动的特点。为数字化工程实现缩短设计周期，降低开发成本和提高产品质量提供了重要支持。面向对象系统中的类模型、状态模型和交互模型在系统重用方面起着重要作用，为了提取被重用系统中的结构和功能信息，以类图、状态图和序列图为例，研究其数据在系统存储文件.sbs包中的组织结构，并且采用VC工具对一组实例图中的信息进行提取。结果表明，通过该存储文件获得的信息完全符合原设计意图，这为管理重用信息提供了数据支持。

Abstract:

As a part of digital project，reuse system can provide important support for digital project by reducing wasteful duplication of efforts so as to shorten design cycles, cut development costs and improve product quality. The class model，state model and interaction model of object-oriented system play important roles in the system reuse. In order to extract the structure and function information from the reuse system，class diagrams, state diagrams and sequence diagrams are taken as examples to study the structure of data in the system files(.sbs) package. VC tools are used to extract information from a set of instance graphs. The results indicate that, the information extracted from the storage file meets the original design requirements, which provides information support for managing reuse data.
