Design of Closed-Loop and LowCarbon Supply Chains - A Perspective from Sustainable Manufacturing Dr Tetsuo Yamada Associate Professor tyamada@uec.ac.jp Management Science and Engineering Program Department of Informatics Graduate School of Informatics and Engineering The University of Electro-Communications, Tokyo, Japan The ASIAN CORE PROGRAM Conference - Sustainable Manufacturing and Environmental Management - VNU University of Economics and Business, Hanoi, Vietnam on Oct 5-7, 2012 (C) 2012 Tetsuo YAMADA 1 Abstract With the Great East Japan Earthquake on March 11, 2011, our daily life notices that supply chains are so important and fragile and also that there are still challenges how to harmonize and visualize the environmental issues and the supply chains One of the reasons is that products with manufacturing by the supply chains inevitably consume natural resources for materials and energy and put out CO2 throughout their whole product lifecycle Therefore, closed-loop and low-carbon supply chains should be designed environmentally and economically This lecture focuses on the environmental issues and the supply chains with the product lifecycle, and overviews the designs and challenges of the closed-loop and the low-carbon supply chains from a perspective of sustainable manufacturing (C) 2012 Tetsuo YAMADA Our Daily life with Assembly Products and Manufacturing • • • • • • • • • Computers Cellular phones Copiers Cameras (Films with lens) TVs Refrigerators Washing Machines Air Conditioners Automobiles etc Supply Chain Maintenance Supply Chain Process (Value Chain Process) Flow of product material Procurement Resource mining Assembly (Production) Disassembly for Reuse/Recycling Earth Sales Use Collection Disposal • Products flow downstream from vendors to plants, plants to distribution centers, and distribution centers to markets Shapiro, J F., Modeling the Supply Chain, DUXBURY, CA, USA, 2001 (C) 2012 Tetsuo YAMADA Supply Chain Network • Network of organizations that are involved, through upstream and downstream linkages, in the different processes and activities that produce value in the form of products and services in the hands of the ultimate customer (Christopher, 1998, p.15) Stadtler, H and Christoph, K., Supply Chain Management and Advanced Planning, Springer-Verlag Berlin Heidelberg, 2000 (C) 2012 Tetsuo YAMADA Japanese Supply Chains Divided by the Japan Earthquake on March 11, 2011 We’ve noticed the importance of the supply chains again!
