Extended Manufacturing Environments (EMEs) are nowadays growing due to the increase on Distributed and Virtual Enterprises, which led to an emergent need to apply scheduling approaches accordingly. This can be achieved in several different ways, namely by putting forward new approaches or by trying to adapt existing ones. In this paper the adaptation of(More)
In this paper we make an XML-based modeling and communication contribution to production scheduling activity. Scheduling problems and resolution methods are modeled in XML. This information modeling is the basis of a web service oriented to scheduling problem solving, which is under development. The resolution of scheduling problems is carried out with the(More)
In this paper we describe an ontology for a model of manufacturing scheduling problems to be solved on the web, through several different scheduling methods made available by a web scheduling decision support system. This approach aims enabling to share scheduling knowledge and methods, in a globally distributed context, in order to facilitate solving these(More)
E-commerce promotes economic growth by enabling online shops to compete within a global market scenario. There are critical success factors that permit to distinguish a good business on the Internet and this knowledge may allow reaching an important competitive advantage for business sustainability. As many disciplines are involved, when determining(More)
Global competition and the customers demand for customized products with shorter due dates, marked the introduction of the Extended Enterprise. In this Extended Manufacturing Environment (EME), lean, virtual, networked and distributed enterprises collaborate to respond to the market demands. In this paper we study the influence of the batch size on Flexible(More)
Recent advancements in Information technology and pervasive applications of Web-enabled services wield a profound influence on manufacturing systems and in particular on distributed networked manufacturing environment. In this paper, a modelling schema is proposed for integrating a distributed feature-based design system to organize concurrent engineering(More)
