碩士 === 大葉大學 === 工業工程與科技管理學系碩士在職專班 === 95 === In the last ten years, the international Green Environment Protection has become the most important subject between governments and industries. The Research Agency of Nations have built the law of international Green Environment Protection and researched the tools for the appraisal of Green issues of industries via the system of evaluation that could get the correct Green Environment information from industries. These efforts also could assist sustainable management of industry. 　 In this thesis, we built the appraisal system of electronics industry base on the law of RoHS and WEEE. First, we utilize the questionnaire investigation to understand the suppliers’ motivation of implementing the green environment protection. Second, we evaluate the performance factors via reviewed suppliers’ information and enforcement effort. The factors include environmental management system, document process system, procurement, and production management system. Third, we integrate experts’ assessment policy of questionnaire investigation to get the index weight by Expert Choice 11 and LINGO to perform the analysis of Analytical Hierarchy Process(AHP) and Choquet-fuzzy-integral model. Finally, we evaluate the green score of suppliers to check which meets the green environment protection in electronics industry then suggest the decision maker to choose the appropriate suppliers. With this research of supplier appraisal system, the performance of environmental management of the regulation restriction and customers’ requirement and that of document process system have the higher fuzzy weights. These two items indicate the importantance to the industries. Obviously, these evaluated results are due to the regulation WEEE and RoHS of European Union(EU). In addition, We observe that the suppliers with high capital emphasize much more on green environment protection, their evaluated scores are also higher.
