Construction and Operation of Sustainable Manufacturing Systems under Ubiquitous Environment

点击翻译按钮获取中文摘要

Devices in recent manufacturing systems are mostly equipped with advanced communication and information processing capability and can easily communicate through the information network. In this study, auction based methods, oneway and two-way auctions and combinatorial auction, are proposed and evaluated as autonomous planning and scheduling method for the effective operation in such manufacturing systems. Embedding such autonomous functions, a concept of real-virtual manufacturing system is also proposed and basic studies to realize and utilize such system are performed. From the global supply chain viewpoint, an international transportation planning problem is formulated as a multi-objective optimization problem taking the environmental issue into consideration, and some solving methods are proposed.
