Abstract
In order to realize the sustainable manufacturing, we need to realize the good balance of environmental and economical efficiencies in business. The purpose of this study is to propose the methodology about generation of business ideas that change existing business to environmentally conscious business (or eco-business). Especially in this study, we focus on two stages of idea generation, i.e., divergence and convergence thinking stages. In the divergence stage, the system helps a designer to generate ideas as many as possible by using the rules for eco-business. In the convergence stage, the system helps to extract hopeful ideas from these ideas by categorizing and qualitatively comparing ideas.
