FMS is recognized as a useful approach to meet with multi-product small-lot-sized production system Large-scaled investment is needed for installing FMS ; full-discussed systematic prefeasibility analysis and preparation study are necessary for successful installation and running the system. Standardization study is one area of the preparation processes ; especially, standardized production strategy is the core in this area. Conceptual framework and case analysis for the standardization process in relation to FMS installation are suggested in this paper. Case analysis is focused in machinary industry.
