Increasingly traditional centralized and sequential manufacturing planning scheduling and control mechanisms are being found to be insufficiently flexible to respond to changing production styles and highly dynamic variations in product requirements. In these traditional hierarchical organizations manufacturing resources are grouped into semipermanent tightly coupled subgroups with a centralized software supervisor processing information sequentially. Besides plan fragility and increased response overheads this may result in much of the system being shut down by a single point of failure. Conventional-knowledge engineering approaches with largescale or very-large-scale knowledge bases become inadequate in this highly distributed environment. 2001 CRC Press LLC The next generation of intelligent manufacturing systems is envisioned to be agile adaptive and fault tolerant. They need to be distributed virtual enterprises comprised of dynamically reconfigurable production resources interlinked with supply and distribution networks. Within .
