生态工业园（EIP）等多领域、异构工业网络中的知识管理是一项具有挑战性的任务。在本文中，基于本体的管理系统已被提出来解决这一挑战。它侧重于电力系统领域，并提供了一个框架，将这些知识与EIP的其他领域相结合。建议的本体，OntoPowSys表示使用描述逻辑（DL）语法和OWL2语言，使它活着。然后，它被用作知识管理系统（KMS）的一部分，在一个虚拟的EIP称为J-Park模拟器（JPS）。所提出的方法的优点是证明了进行两个案例研究的JPS。第一个案例研究说明了最优潮流（OPF）在JPS电网中的应用。第二个案例研究在理解JPS的生物柴油厂中化学和电气工程领域之间的跨领域相互作用方面起着重要作用。这些案例研究可在联合采购处网站上作为网络服务查阅。研究结果表明，在决策支持工具的开发中使用本体的优势。这些工具能够在决策过程中考虑数据之上的上下文信息。他们还能够在不同的领域交换知识，而不需要通信接口。
Knowledge management in multi-domain, heterogeneous industrial networks like an Eco-Industrial Park (EIP) is a challenging task. In this paper, an ontology-based management system has been proposed for addressing this challenge. It focuses on the power systems domain and provides a framework for integrating this knowledge with the other domains of an EIP. The proposed ontology, OntoPowSys is expressed using a Description Logics (DL) syntax and the OWL2 language was used to make it alive. It is then used as a part of the Knowledge Management System (KMS) in a virtual EIP called the J-Park Simulator (JPS). The advantages of the proposed approach are demonstrated by conducting two case studies on the JPS. The first case study illustrates the application of optimal power flow (OPF) in the electrical network of the JPS. The second case study plays an important role in under-standing the cross-domain interactions between the chemical and electrical engineering domains in a bio-diesel plant of the JPS. These case studies are available as web services on the JPS website. The results showcase the advantages of using ontologies in the development of decision support tools. These tools are capable of taking into account contextual information on top of data during their decision-making processes. They are also able to exchange knowledge across different domains without the need for a communication interface.
