ISAPS is a scheduling and planning tool for shop floor personnel working in a Flexible Manufacturing System (FMS) environment. The ISAP system has two integrated components: the Predictive Scheduler (PS) and the Reactive Scheduler (RS). These components work cooperatively to satisfy the four goals of the ISAP system, which are: (G1) meet production due dates, (G2) maximize machining center utilization, (G3) minimize cutting tool migration, and (G4) minimize product flow time. The PS is used to establish schedules for new production requirements. The RS is used to adjust the schedules produced by the PS for unforeseen events that occur during production operations. The PS and RS subsystems have been developed using IntelliCorp's Knowledge Engineering Environment (KEE), an expert system development shell, and Common LISP. Software Quality Assurance (SQA) techniques have been incorporated throughout the development effort to assure the ISAP system meets the manufacturing goals and end user requirements. 5 refs., 4 figs.
