Abstract

The recycling process of ELV consists of three phases: dismantling, shredding and ASR treatment. Dismantling is the collection of reusable parts and the most important phase. The types of dismantling system is diverse and each country has different characteristics. Therefore, the selection of a suitable ELV dismantling system for a target country is dependent on the characteristics of each country. But the characteristics of country data changes every year and is insufficient and ambiguous. In this study, fuzzy inference and modified QFD (Quality function deployment) methods are utilized to solve the problems. The fuzzification of characteristics data for each country, customized rules and decision of modified QFD matrix are developed, which is applied to sample countries.

폐자동차는 재활용 자원의 주요 원천이며 폐자동차 재활용 과정은 해체, 파쇄 및 ASR 처리 단계로 구분된다. 폐자동차 해체는 재사용 가능 부품을 수집하는 등 매우 중요한 단계인데, 크게 독립형(island type)과 라인형(line type) 으로 구분할 수 있고 다양한 유형의 해체 시스템이 존재한다. 또한 국가별 법적 규제, 폐자동차 발생량, 인구밀도, GNP 등 국가 별 특성이 다르기 때문에 특성에 맞는 적절한 해체 시스템을 체계적으로 선정하는 방법이 필요하다. 본 연구에서는 퍼지이론 및 변형 QFD를 활용하여 국가 특성에 대한 데이터 퍼지화 및 해체시스템 적합도를 평가하는 방법을 개발하였으며, 관련 데이터를 보유한 대표 국가에 대해 적용하고 결과를 평가하였다.
