- A mediator-based approach for decentralised production planning, scheduling and monitoringPublication . Tönshoff, H.-K.; Seilonen, Ilkka; Teunis, Gerrit; Leitão, PauloThe improvement of business processes along the supply chain has become a focus in industry and research during the past decade. Based on advanced technologies for communication and data structuring this paper describes a software system called the Mediator that provides support for integrating decision-making of several separate actors in decentralized business organizations. The Mediator is designed to offer an adequate level of decision-making integration, taking into account the effort needed for the integration of heterogeneous computer systems by use of the Extended Mark-up Language (XML). The approach is demonstrated for industrial pilot cases in multi-site and supply-chain production.
- Mediator-based communication, negotiation and scheduling for decentralised production managementPublication . Seilonen, Ilkka; Teunis, Gerrit; Leitão, PauloRecent trends in industry towards autonomous and co-operative production systems and latest developments in data network technologies have created new opportunities for enhancing the co-operation of production networks. In order to take advantage of the emerged opportunities, an approach based on a software system called Mediator has been developed. The Mediator provides order planning support necessary to integrate decisionmaking and scheduling of several actors in decentralised business organisations. The approach will be demonstrated in the context of order planning in multi-site and supplychain production.
- A new architecture for flexible shop control systemsPublication . Teunis, Gerrit; Leitão, Paulo; Madden, MichaelIn the last two decades, there has been a marked trend in manufacturing away from function-centered production organisations towards product-based manufacturing shops and smaller organisational units. These new organisational structures reduce management complexity and facilitate greater human involvement and empowerment. Modern manufacturing facilities must be flexible, to allow for rapid reconfiguring of resources as dictated by variable demands. Today's tools for production planning and scheduling are not flexible enough, most of them being based on a certain production structure. A newly developed kernel/shell technology aims at a software architecture for shop control not being based on any assumption of the production structure. It should be possible to support almost any structure, organisation and scheduling algorithm. A central kernel acts as a service provider for a broad array of shell modules for scheduling, interfacing with legacy systems, database I/O, user interaction, SCADA interfacing, etc. This technology for shop control provides a high degree of customisation, flexibility and extendibility.
