Abstract

On automated manufacturing system, it is commonly difficult to execute real production according to the schedule planned in advance because of the external fluctuations such as order change and delayed delivery of materials, and internal uncertain factors such as machine failure and process delay existing in real shop floor. In this study, a new concept of agent-based Real-Virtual Fusion Manufacturing System (RVF-MS) is proposed, which aims to adaptively and effectively consider both the external and internal fluctuations by realizing the fusion between real production shop floor (real system) and manufacturing simulation (virtual system). In this paper, a method of constructing virtual system in dynamic manufacturing environment is proposed, and effectiveness of the proposal is verified by experiments about production planning problem on flexible flow shop using model plant.
