A new classification scheme for flexible manufacturing systems

Abstract

A new classification scheme for flexible manufacturing systems (FMS) based on a consistent set of definitions which emphasizes the number and characteristics of the material handling devices as well as the configuration of the processing elements is introduced. Within a broad definition of FMS, four specific types of FMS are defined: a single flexible machine (SFM); a flexible manufacturing cell (FMC); a multi-machine flexible manufacturing system (MMFMS); and a multi-cell flexible manufacturing system (MCFMS). The relationships and boundaries between these four types of FMS are discussed. The hierarchical nature of the classification scheme is emphasized. It is shown that flexible manufacturing systems described in the literature are easily classified using the new scheme. The approach introduced here provides a firm basis for the description of flexible manufacturing systems which highlights essential characteristics and allows comparative evaluation and assessment. In research studies it provides a clear hierarchical framework for the study of operational and control aspects of systems.
