| Abstract: | The operational level of flexible manufacturing systems FMS is concerned with the detailed decision making required for real-time operation. The real-time control of FMS is extremely complex. On-line scheduling is referred to as real-time control of FMS. On-line scheduling of an FMS requires decision making in various scheduling problems such as selection of an AGV and a workcentre from a set of workcentres simultaneously requesting the service for transport of a part, selection of a new part type to be released into the system, etc. This paper describes a prototype knowledge-based system for selection of an AGV and a workcentre from a set of workcentres simultaneously requesting the service for transport of a part in on-line scheduling of FMS. The knowledge-based system is evaluated by the empirical approach. On-line scheduling of FMS gives potential advantages such as productivity and low throughput time. |
