The production of aircraft structure parts is featured by multiple varieties and small batches, which imposes significant challenges for the representation of process knowledge. Feature based method is an effective way as the process knowledge carrier. Although the parts are different from each other, they are composed of similar geometric features with similar machining processes. This paper introduces...
In high-level-architecture (HLA)-based distributed heterogeneous collaborative engineering environments (CEEs), the construction of federation object model files is time consuming. This paper presents an ontology fusion approach aiming at establishing a common understanding in such collaborative environments. The proposed approach has three steps: ontology mapping, ontology alignment, and ontology...
This paper presents a novel ontology fusion approach which aims to establish a mutual understanding among HLA (High Level Architecture) -based distributed heterogeneous collaborative product development systems. The approach includes three steps: ontology mapping, ontology alignment and ontology merging. It adopts an axiom-based deduction ontology fusion strategy, and takes heavy weighted ontologies...
Semantic integration is crucial for successful collaboration between heterogeneous information systems in an open environment. Traditional ontology-driven approaches rely on the availability of explicit ontologies. However, in many domains, this prerequisite cannot be met. In order to address this issue, this paper investigates the theoretical foundation of ontologies and extends the traditional ontology...
This paper presents a novel ontological view-based semantic transformation method to address the semantic heterogeneity design issue of open distributed information systems. After carefully reviewing the traditional ontology definitions, this work extends the ontological view concept to represent the partial knowledge about the same business domain in an open environment where common ontology does...
Today in many domains there are very limited explicit ontologies established for building information systems. The information systems have only schemas for their information repositories which to some extent imply the semantics of the information. Traditional ontology-driven semantic integration approaches cannot be directly applied in integrating these information systems. In our work we use the...
This paper presents a Service-Oriented Coordinated Intelligent Rational Agent (SO-CIR-Agent) model to address three design issues of open Cooperative Distributed Systems (CDS): autonomy, distribution, and heterogeneity. This work incorporates the service-oriented design paradigm, agent-oriented design paradigm, and Web service technology as supporting pillars by extending the CIR-agent model so that...
This paper presents an amphibian service-oriented agent model (SOAM) to address three design issues facing modern distributed information systems: autonomy, distribution, and heterogeneity. This work incorporates the service-oriented design paradigm, agent-oriented design paradigm, and Web service technology as supporting pillars by extending the coordinated intelligent rational agent (CIR-Agent)...
