Flexible Manufacturing Systems (FMS)An FMS is a reprogrammable manufacturing system capable of producing a variety of products automatically. Conventional manufacturing systems have been marked by one of two distinct features:The capability of producing a variety of different product types, but at a high cost (e.g., job shops).The capability of producing large volumes of a product at a lower cost, but very inflexible in terms of the product types which can be produced (e.g., transfer lines).An FMS is designed to provide both of these features.

Classification of FMS-related ProblemsStrategic analysis and economic justification, which provides long-range, strategic business plans.Facility design, in which strategic business plans are integrated into a specific facility design to accomplish long-term managerial objectives.Intermediate-range planning, which encompasses decisions related to master production scheduling and deals with a planning horizon from several days to several months in duration.Dynamic operations planning, which is concerned with the dynamic, minute-to-minute operations of FMS.

FMS ProblemsPart type selection (Askin) - selecting parts that will be produced in the FMS over some relatively long planning horizon.Part selection (Stecke) - from the set of parts that have current production requirements and have been selected for processing in the FMS, select a subset for immediate and simultaneous processing.Machine grouping (Stecke) - partition machines into groups where each machine in a group can perform the same set of operations.Loading (Stecke) - allocate the operations and required tools of the selected part types among the machine groups.Control - provide instructions for, and monitor the equipment in the FMS so that the production goals identified by the above problems are met.
