Summary: | 碩士 === 國立清華大學 === 工業工程與工程管理學系 === 101 === Nowadays,there are more and more legislation concerningwith environmental issues. In order to be more sustainable for the product, the companiesre-design products to reduce the environmental impact. So as to design the sustainable products in the design stage, this study assess the greenhouse gases of the product which is calculated by the components of transportation, manufacturing processes and assembly methods. Then those components are separated into the modules which canmake the product recycling easierby the parts material and it can make products greener. However, todesign the product during the sustainable process can meet the economy, this study examines the costs and line balancing.To be able to achieve above purpose, the study develops a mutation particle swarm optimization (MPSO) algorithm to calculate the approximate optimal green module and cost module. The goal of the green module is using the assembly methods and assembly sequence to calculate the minimize greenhouse gases and meet the module recycling. The goal of the costmodule is the minimize totalcosts. Then the study changes different parts materials which influenceon the impact of greenhouse gases.
This study considersthe product ofsustainability, assembly, recycling and modularization at the design stage. Therefore, the product can be rapidly launched after mass-production and the redesign time for environmental protection conformity can be reduced. In recycling, the studyconsiders placing the components of the same material in the same module. Therefore, the components can be more easily recycled at the end of product life cycle.Moreover, when the product consists of more components which lead a complex structure, the studywill use modularized for clustering product. That can be the structure of the product simplification and reduce confusion in the production. The study provides designers with the greenmodule, the cost module and the different materialsmodule, and the designer can choose the right design strategic for company.Finally the study discusses the different green indicators effecting fortotal costs thatenable the designer to get the good balance withthe costs and sustainability.
