Abstract
In this study, a methodology named Real-Virtual Fusion Manufacturing System (RVF-MS) based on CPS (Cyber Physical Systems) concept is proposed. It is designed as multi-agent systems and aims to adaptively and effectively deal with both external and internal fluctuations in real production shop floor. In this paper, an auction method to determine equipment agents to participate in decision-making in the virtual system under equipment failure is proposed. In the proposed method, the coordinator is failure equipment agents, bidders are equipment agents on the same process of the failure equipment, goods are unprocessed jobs assigned to failure equipment, respectively. In order to determine alternative equipment agents, coordinator implements auction. The effectiveness of the proposed method is verified by computational experiments.
