The objective of this paper is to explore the state-of-the-art in generative process planning as it seems most suitable for the concept of Mass Customization (MC). Particular importance is attributed to special requirements of MC on the practice of process planning as it becomes an integral part of the value chain. Based on the literature review and the extended requirements of MC, the need for...
