A hybrid multi-agent system architecture for enterprise integration using computer networks

The manufacturing industries are now experiencing fierce pressure of competition from every corner on this planet. In addition, the advancement in computer networks and information technologies has been gradually reshaping the manufacturing companies by shifting from the industrial age to the information era. Due to these elevated competitiveness and advanced computer technology, a number of new manufacturing and management strategies (e.g., CE or CIM) have emerged for the innovation of manufacturing enterprises. Although they have different definitions and scopes, there are several common issues: inter-enterprise functions integration; inter-enterprise resources integration; and collaboration. This paper proposes a new multi-agent system (MAS) architecture to support the inter-enterprise functions/resources integration and collaboration over the networked environment, including the hybrid agent architecture and hybrid network architecture. In contrast to the existing agent architectures, the proposed agent architecture enables agents to exhibit the hybrid (continuous and discrete) behavior and interactions. In addition, our network architecture is more suitable for building the large-scale distributed manufacturing systems that are prone to dynamic random changes of their environment. Based on the proposed MAS architecture, a collaborative product development environment is implemented as a starting point, and a multidisciplinary team-oriented design problem is illustrated to provide the vision of the proposed MAS architecture.

A reference system for internet based inter-enterprise electronic commerce

As supply chain management and its global outsourcing are widely spread recently, many researches and development focus on integration of inter-enterprise information systems. The most important factors to achieve inter-enterprise integration are standardization and digitalization. The objectives of this work are to develop the reference model for internet based inter-enterprise electronic commerce and to implement a prototype system for its fundamental issues such as business process, information standards, and information system integration. The electronics assembly processes are chosen as the target industry. For the reference architecture of inter-enterprise electronic commerce, we also investigate intra-enterprise business processes and model them with IDEF0. The standard documents and its items are defined from analysis of traditional documents for outsourcing processes and EDI documents. For standard exchange method, web-based XML is adopted, and corresponding DTD and XSL for RFQ and Quotation are developed. In order to prove feasibility and effectiveness of the reference system a prototype system is introduced and implemented.

An agent-based service-oriented integration architecture for collaborative intelligent manufacturing

The rapidly changing needs and opportunities of today's global market require unprecedented levels of interoperability to integrate diverse information systems to share knowledge and collaborate among organizations. The combination of Web services and software agents provides a promising computing paradigm for efficient service selection and integration of inter-organizational business processes. This paper proposes an agent-based service-oriented integration architecture to leverage manufacturing scheduling services on a network of virtual enterprises. A unique property of this approach is that the scheduling process of an order is orchestrated on the Internet through the negotiation among agent-based Web services. A software prototype system has been implemented for inter-enterprise manufacturing resource sharing. It demonstrates how the proposed service-oriented integration architecture can be used to establish a collaborative environment that provides dynamic resource scheduling services.     

A web services-based approach to develop a networked information integration service platform for gear enterprise

In order to deal with the problems of information integration and data sharing across distributed heterogeneous application systems in gear enterprises, it is imperative to build up a high quality information integration platform. Web Services, an emerging form of service-oriented architecture (SOA) for distributed computing, have the potential to serve as a key enabling technology to integrate heterogeneous systems under the distributed environment. This paper presents a novel information integration service platform which offers better support for the networked manufacturing of gear enterprise by taking full advantage of technologies of SOA and Web services. In this paper, the information integrated operation mode of gear enterprise networked manufacturing is deeply analyzed and the functional architecture of the networked information integration service platform is proposed. Furthermore, the application integrated framework of gear enterprise is constructed and the software architecture of the service platform is implemented in the .NET environment. Finally, an actual application example of hypoid gear networked manufacturing is provided to demonstrate the practicability of the proposed platform.

Federated integration of networked manufacturing service platforms

Networked manufacturing is an advanced manufacturing pattern that was born of information technologies and suits the networked economic environment. Networked manufacturing service platforms have been widely established to support this new pattern. Since the island problems are retarding further development of networked manufacturing, integration of existing networked manufacturing platforms is in demand. A federated integration mode is proposed to integrate the existing networked manufacturing platforms and provide a large-scale distributed resource sharing and cooperative environment. The nature of federated integration is discussed, and the architecture of federated integration system was put forward along with a set of rules and three types of integration services. Two key issues in federated integration are discussed in detail. One is the federation management, including the hierarchy of federations, the basic states of federations and the state-keeping mechanism using factory/instance pattern. The other issue is the authentication, authorization and access control in across-platform applications. Finally, an implementation is presented.
