Real-Virtual Fusion Manufacturing Scheduling with Social Contract-Based Approach at Operational Phase

Abstract

In this study, a new concept named Real-Virtual Fusion Manufacturing System (RVF-MS) is proposed, which aims to adaptively and effectively deal with both external and internal fluctuations by realizing a fusion between real production shop floor and virtual manufacturing system model. A concept based on multi-agent system is used for constructing dynamic model in the virtual system. In this paper, production scheduling method at operational phase for RVF-MS is proposed, in which a social contract-based approach named Combinatorial Auction (CA) is applied. The effectiveness of the proposed method is verified by computational experiments for flexible flow shop problems.
