Abstract

Green IT, composed term with Green and Information Technology(IT), use IT for energy savings and carbon emission reductions. Green IT went beyond the scope of greening IT, and recently it's concept is expanded as far as counterplan of climate change including greening other industries by IT. 85% of total greenhouse gas emissions from the energy sector and 20% of them comes from transport parts, so it is time to research IT for automotive industry. In this paper, we take up the knowledge based fuzzy logic to provide life cycle analysis associated with greenhouse gas emissions for industry produced warranty claims frequently such as automobile industry. We propose a analysis method of warranty claims using expert knowledge about the warranty in car exhaust systems related to greenhouse gas emissions, past test results of malfunction, analysis of past field data, and warranty data. Furthermore, we propose life knowledge-based GWS (Greenery Warranty System). We demonstrate the applicability of IT in eco-friendly automotive industry by implementing knowledge-based fuzzy logic and applying.

환경을 의미하는 녹색(Green)과 정보기술(IT)을 합성한 용어인 그린 IT는 에너지 절감과 탄소배출 감축을 목표로 IT 기술을 활용하고 있다. 그린 IT는 IT산업을 친환경화 하기 위한 범위를 벗어나서, 최근에는 IT를 활용한 타 산업분야의 그린화를 포함하여 기후변화 대응 방안으로까지 개념이 확장되고 있다. 전체 온실가스 배출량의 85%를 에너지 부문이 차지하고 있으며, 그 중에서도 수송부분이 20%를 차지하고 있는 만큼 자동차 산업 분야를 위한 IT의 연구가 필요한 시점이다. 본 논문에서는 자동차와 같이 보증 클레임이 빈번하게 발생되는 산업 분야의 온실가스 배출과 관련된 수명주기 분석을 제공하기 위하여 지식 기반 퍼지 로직을 이용한다. 온실가스 배출 관련 자동차 배기 시스템에 대한 보증 전문가 지식, 과거 오작동 테스트 결과, 과거 현장 분석 및 보증 데이터를 이용한 보증 클레임 분석 방법을 제안하였다. 또한, 수명 지식 기반의 GWS(Greenery Warranty System)를 제안하였다. 지식기반 퍼지 로직을 직접 구현하여, 실무에 적용함으로써 친환경 자동차 산업에 IT의 적용성을 증명하였다.
