PPP项目残值风险本体知识库的构建与应用

Development and Application of Ontology for Residual Value Risks in PPP Projects

摘要:

PPP项目在建设与运营阶段面临众多风险,移交时的残值风险的控制管理是PPP项目取得持续健康发展的重要保证。本文从PPP项目残值风险的知识管理的角度出发,构建了残值风险的本体知识库并结合具体案例进行应用分析。通过对PPP项目残值风险的文献回顾,对该风险的形成机理进行研究,建立PPP项目残值风险的知识框架。同时,定义知识框架里各个概念及其结构层次,并对概念之间的关系和属性进行知识表示,再根据SWRL语言对概念关系进行适当推理。最后,论文采用本体编辑软件Protégé构建了Sky大桥项目的残值风险本体知识库,对知识进行更有效的表达,促进其可共享性和可传递性,实现更深入的信息查询和数据处理功能。

Abstract:

Aiming at improving the knowledge management in PPP projects, the development of an ontology-based knowledge base for Residual Value Risk (RVR) in PPPs was conducted. Through literature review and typical case study of knowledge management in PPP projects, the RVR in PPP projects was analyzed from the perspective of risk structure, risk process and vulnerability, based on which the formation mechanism of RVR was explored. The RVR was deconstructed into five risk consequences. Furthermore, an improved RVR framework was established as a platform for organizing all kinds of knowledge for RVR in PPPs. Meanwhile, in order to express knowledge more effectively and promote their sharedness and transferability, the knowledge base was built by means of Ontology. Finally, the ontology editing software Protégé was used to build ontology-based RVR knowledge base, to achieve a more in-depth data processing function. The study can be used to analyze risk probability and vulnerability for both of public and private sectors in PPPs.
