A survey and critical review of flexibility measures in manufacturing systems

Abstract

Flexibility of manufacturing systems is currently under intensive study, and the need for objective measurement of this important characteristic is widely expressed. Measurement of manufacturing flexibility is being increasingly discussed in the literature on manufacturing systems. This paper surveys the literature dealing with quantification of certain types of flexibility, analyses the proposed measures, and presents critical views. Approaches to developing flexibility measures are compiled and classified. Discussion on the suitability of specific measures is provided. Requirements of flexibility measures and recommendations for future research in this area are also provided.
