A procedure is outlined that addresses the decision of whether a tool should or should not be replaced prior to its processing of a workpart. The proposed procedure attempts to minimize the tool-related economic losses associated with these decisions while maximizing part throughput. The limitations of both the human and the computer at achieving both of these system performance objectives are discussed and form the basis to the proposed procedure. Based on a simulation study examining human capabilities at making tool-replacement decisions, various heuristics employed by humans who were successful at performing this task were identified. The article concludes with a discussion on the role of sensitivity analysis, and the use of the procedure within the context of human supervisory control of FMSs.
