ABSTRACT<BR>
This article presents the HOLOS System, a control architecture infrastructure to be applied on dynamic scheduling. It is knowledge based, open, distributed (multi-agent), flexible, integrated, object-oriented, extendible and modular. The architecture infrastructure supports the virtual manufacturing concept and, at the same time, allows the integration of existing equipment. Negotiation technique is applied for production resources allocation, which increases the control flexibility during a schedule generation, specially in the presence of disruptions. The Consortium concept is introduced as a support for improving several types of production flexibility of an enterprise. Finally, some implementation aspects are presented as well as current problems and advantages of HOLOS.
