Remanufacturing is an industrial manufacturing process. The merits of manufacturing are to reuse old products to perform like a new product and to save energy, natural resources, landfill space and to reduce air pollution by less re-smelting. This paper proposes a systemic approach for activating the domestic remanufacturing industry. The approach is based on inside and outside regulations to apply remanufacturing companies. And, we analyzed the state and problems of remanufacturing industry for automobile parts.

Remanufacturing is restoring or manufacturing the worn-out or discarded components of an end of life product in order to bring it to the "like new" condition. The aim is to reprocess used products in such a manner that the quality of the products is as good as or better than the new one, in terms of appearance, reliability and performance. This paper investigates the automotive remanufacturing industry in Europe. To further knowledge in this field, the paper focuses on the remanufacturing of the automotive components of end-of-life vehicles. The paper scope emphasizes key remanufacturing companies, which are identified and were surveyed in terms of their business structures. The research aims to address the potential for growth within the remanufacturing industry, with regard to various players. The state of the art in remanufacturing of automotive equipment will be identified.

Continuous industrial development has led to a better quality of life for everyone, even further accelerating industrial growth. Industrial development, however, has also caused environmental degradation, which is posing a serious threat to humanity. It has also encouraged the indiscriminate use of limited resources, causing resource depletion. Efficient resource management based on resource circulation is critical to saving resources. Resource circulation methods are as follows: reducing the use of resources in the manufacturing process, recycling used or reprocessed products and reusing used resources without being reprocessed, remanufacturing with end-of-life products with disassembled parts. Furthermore, remanufacturing process including cleaning, inspection, repairing, and reassembling facilitate performance level as well as new typical products. It is noteworthy that the remanufacturing of machine tools can significantly save resources because their structural parts are substantially large in size. Machine tools have served as a foundation for the manufacturing industry, which has driven Korea's industrial development. Nevertheless, a few research has been reported for remanufacturing technology with used machine tools. Relevant research of developing a remanufacturing process chart and method is prerequisite for saving the resource and environments.

Remanufacturing is a process that restores old products to perform like new, while saving energy, reducing consumption of natural resources, and lowering environmental emissions. By extending the product life cycle, remanufacturing approaches enable closed loop material cycles that are ultimately necessary for a sustainable society. This paper provides some description of the current automotive remanufacturing enterprise, with a particular emphasis on key vehicle components that are currently remanufactured. The analysis yields two major conclusions. First, volume of the USA automotive after sales and remanufacturing industry market is estimated. Second, market price of a remanufactured component in the automotive sector is surprisingly uncorrelated with the number of companies engaged in remanufacturing that component - at least for companies registered with the Automotive Parts Remanufacturing Association (ARPA).

In this paper, it was performed to protect the remanufacturing industry of domestic automobile part and grasp the latest tendency of remanufacturing industry of domestic automobile part for development of remanufacturing technology and economical support of government. Research on the present statue of the remanufacturing industry was indicated that the number of remanufacture enterprises about automobile part, the annual, the number of employee in remanufacture and the type of remanufacturing. The general problems were presented which blocked the activities of domestic automobile part. It was also presented that problem of remanufacturing technology side and quality assurance of remanufactured automobile part and found out solution.

증가하는 소비의 추세, 한정된 자원, 폐기물 처분등의 문제로 인하여, remanufacturing 에 대한 관심이 더욱 높아져가고 있다. Remanufacturing 에 대한 생산계획 및 스케줄링은 높은 불확실성으로 인하여 기존의 방법들과 별개로 다루어져야 한다. 본 연구에서는 manufacturing/remanufacturing 생산 시스템에서의 생산계획을 위한 수정된 유전 알고리즘(GA)을 제안하였다. GA 의 chromosome 은 각 부품의 생산 수준을 의미하며, 알고리즘을 이용하여 중간조립품과 최종제품의 분해/조립 계획을 결정할 수 있다. 임의로 생성된 문제들에 대해 실험한 결과, 다양한 문제들에 대하여 적용 가능하다는 것을 알 수 있었다.

remanufacturing 시스템의 공정을 다룬 모델은 그들의 경제적인 결론 평가에 집중하여 보여졌다. 특별히 이러한 모델은 분리된 구성품의 목적과 정도에 대한 의사결정을 보조하였으며, 결론적으로 복구될 수 있는 아이템의 경제적 가치를 사용 이러한 아이템의 재고 보유 원가를 얻을 수 있다고 하였다. 이러한 정보는 재고 관리 정책 결정을 위해 사용될 수 있으며 경제적 가치에 접근하기 위해 이상의 평균 원가 접근은 순 현재 가치 방법으로 비교할 수 있다. 재고관리 관점으로부터 remanufacturing 시스템에서의 수집 방식을 추가하여 고려하였으며, 향후 폐차업의 리싸리클링 분야에 접목하고자 한다. 경제적 평가 모델로부터의 반영된 결과는 remanufacturing 시스템뿐만 아니라 체계적인 평가를 제조업에서 추가하여 연구 할 수 있다.

Post industrial technologies have improved human standard of living, however, a host of negative environmental consequences from the unlimited industrial appetite have posed serious global challenges. Remanufacturing is an industrial manufacturing process that is to restore old products to perform like a new and to save energy, natural resources, landfill space and to reduce air pollution by less re-smelting. By extending product life cycle, remanufacturing gives us enormous opportunities for sustainable development of our society. This paper introduces current state of the art and future perspective in the field of automotive remanufacturing focusing on alternator and start motor. The results could be used as a basic information for further remanufacturing applications in Korea.

Recently, the optimisation of end-of-life (EOL) product remanufacturing processes has been highlighted. In particular, computer remanufacturing becomes important as the amount of disposed of computers is rapidly increasing. At the computer remanufacturing, depending on the selections of used computer parts, the value of remanufactured computers will be different. Hence, it is important to select appropriate computer parts at the reassembly. To this end, this study deals with a decision making problem to select the best combination of computer parts for minimising the total remanufacturing computer cost. This problem is formulated with an integer nonlinear programming model and heuristic search algorithms are proposed to resolve it.

This papers focuses on remanufacturing processes in a closed loop supply chain. The remanufacturing processes is considered as one of the effective strategies for enterprises' sustainability. For this reason, a lot of companies have attempted to apply remanufacturing related methods to their manufacturing processes. While many research studies focused on the return rate for remanufacturing parts as a control parameter, the relationship with demand certainties has been studied less comparatively. This paper considers a closed loop supply chain environment with remanufacturing processes, where highly fluctuating demands are embedded. While other research studies capture uncertainties using probability theories, highly fluctuating demands are modeled using a fuzzy logic based ambiguity based modeling framework. The previous studies on the remanufacturing have been limited in solving the actual supply chain management situation and issues by analyzing the various situations and variables constituting the supply chain model in a linear relationship. In order to overcome these limitations, this papers considers that the relationship between price and demand is nonlinear. In order to interpret the relationship between demand and price, a new price elasticity of demand is modeled using a fuzzy based nonlinear function and analyzed. This papers contributes to setup and to provide an effective price strategy reflecting highly demand uncertainties in the closed loop supply chain management with remanufacturing processes. Also, this papers present various procedures and analytical methods for constructing accurate parameter and membership functions that deal with extended uncertainty through fuzzy logic system based modeling rather than existing probability distribution based uncertainty modeling.
