The operational level of flexible manufacturingsystems (FMS) is concerned with the decisionmaking required for real-time operation. The real-time controlof FMS is extremely complex. On-line scheduling isreferred to as real-time control of FMS. On-line schedulingof an FMS requires decision making in various schedulingproblems such as selection of an AGV and a workcentre from a set of workcentres simultaneously requesting the service fortransport of a part, selection of a new part type to be releasedinto the system, etc. This paper describes a prototype knowledge-based system for selection of an AGV and a workcentrefrom a set of workcentres simultaneously requesting theservice for transport of a part in on-line scheduling of FMS.The knowledge-based system is evaluated by the empiricalapproach. On-line scheduling of FMS gives potential advantagessuch as productivity and low throughput time. © 1997 Taylor & Francis Group, LLC.

There is a general challenge offered to the field of engineering economics by the introduction of advanced technologies. A survey of the existing literature on evaluation of advanced manufacturing systems indicate that the traditional approaches are inadequate for the purpose. Typically new technologies require very high investments. The traditional approaches do not account for the significant but intangible benefits offered by new technology. In this paper, an attempt has been made to overcome the above deficiencies by presenting an approach to account for the justification of the manufacturing system. This is based on the analytic hierarchy process (AHP) and is capable of taking into account many intangible factors as well. The usefulness of the proposed approach is demonstrated through a case situation. Finally, some research directions for future work are identified. © 1992.
