Outline of Final Research Achievements

An analytical method and a design tool were developed toward construction of supply chains (SCs) that are robust and flexible against risks. First, a concept of SC risk was marshalled from the survey on actual domestic and international SCs. A comprehensive SC matrix database for Japanese 2,000 products was developed utilising the life cycle inventory database and material flows in global supply chain and concentration of the flows were also detected. Subsequently, a mathematical framework for evaluating vulnerability of SCs was developed and SC risks including geographically uneven distribution of domestic products were visualised using the SC matrix database developed and the material flows detected. Furthermore, the priority of final products supply was considered from household consumption expenditure assessment and the robustness and flexibility of recycling systems were also addressed as both the waste treatment and the supply source of recycled materials.
