재제조 산업은 환경을 보존하면서 제조 시 사용되는 자원과 에너지를 줄일 수 있는 대안으로 알려지고 있다. 한국에서 재제조 산업을 활성화 하기 위해선, 원제조업체, 재제조업체 그리고 수리업체 사이의 협력을 지원하기 위해 기본 원칙을 제정하여야 한다. 재제조 활성화를 위한 기본 원칙들은 재제조 절차와 주요 구성원간의 관계분석에 의해 평가될 수 있다.

재제조는 사용 후 제품을 일련의 과정을 거쳐 신품의 성능수준으로 복원하는 방법으로 물질 재활용에 비하여 자원에너지 절감효과가 높고 환경부하가 작아 경제성과 환경성을 동시에 만족하는 고부가가치 자원순환방법이다. 재제조를 통한 자원순환은 최근 이슈가 되고 있는 자원수급 불균형 및 일자리 부족 등의 문제 해결에도 크게 기여할 수 있다. 이에 본 연구에서는 재제조의 특성 및 효과를 고찰하고, 우리나라와 미국, 유럽, 일본, 중국 등 해외 주요국의 재제조산업 현황, 기술수준, 제도 등을 비교, 분석하여 문제점을 도출하였으며, 이를 바탕으로 국내 재제조산업 활성화를 위한 발전 과제를 제시하였다.

현재 우리나라의 차량 증가에 따른 폐차도 증가추세에 있어 이에 따른 각종 환경오염 문제로 인해 자원 재순환에 대한 관심이 고조되고 있는 실정이다. 본 연구에서는 국내 자동차 부품 재제조시장의 사업도입에 따른 경제적 효과를 정량적으로 평가하고자 자동차의 부품중 상대적으로 재제조율이 낮은 부품인 범퍼, 도어, 펜더에 대해서 비용편익을 분석하였다. 분석 결과 각각 비용 편익은 제품별 개당 54,000원으로 발생하는 것으로 나타났고, 신제품의 50%를 재제조할 경우 매립비용의 절감으로 개당 226,060원의 이익이 발생하는 것으로 나타났다. 이와 같이 범퍼, 도어, 펜더를 재제조 했을 경우 상당한 편익이 발생하여 재제조업체의 충분한 경제성 확보가 가능할 것으로 판단된다.

This paper considers a remanufacturing and purchasing planning problem, in which either used products(or wastes) are remanufactured or remanufactured products(or final products) are purchased to satisfy dynamic demands of remanufactured products over a discrete and finite time horizon. Also, as remanufactured products are purchased more than or equal to a special quantity Q, a discount price policy is applied. The problem assumes that the related cost(remanufacturing and inventory holding costs of used products, and the purchasing and inventory holding costs of remanufactured products) functions are concave and backlogging is not allowed. The objective of this paper is to determine the optimal remanufacturing and purchasing policy that minimizes the total cost to satisfy dynamic demands of remanufactured products. This paper characterizes the properties of the optimal policy and then, based on these properties, presents a dynamic programming algorithm to find the optimal policy. Also, a network-based procedure is proposed for the case of a large quantity of low cost used products. A numerical example is then presented to demonstrate the procedure of the proposed algorithm.

Recycling involves processing used materials into new products and remanufacturing is an industrial process in which worn-out products are restored to like-new condition. Recycling and remanufacturing industry is environmentally and economically important industry and provides significant benefits to prevent waste of potentially useful materials and reduce energy usage. The purpose of this research is to investigate the trend of recycling and remanufacturing industry in Korea and other countries like Germany, Japan and America. The yield information is generally quite valuable to promote green growth industry as an important alternative in the 21st century.

The rise in population and the increase of urbanization and industrial growth has resulted in an ever-increasing volume of municipal solid waste that must be regularly collected, transported, and ultimately disposed of. Therefore, over the last decade the public, commercial and legislative awareness of environmental issues has been increased dramatically on earth particularly some industrial countries which has a shortage of landfill capacity. A quality, cost and delivery lead-time are usually considered as the competitive factors for each industry. However, the concepts of environmental issue are emerging common terms and concerns more seriously. More attention than ever is being focused on the recycling and source reduction techniques to reduce the total volume of waste. Unfortunately, however, a shortage of landfill capacity and increasing disposal cost requests a fundamental solution about the environmental issue. That is the remanufacturing which allow manufacturers to minimize waste, production cost and to turn end-of-life product into a profitable product. The objectives of this research were to growth the remanufacturing system by suggesting issues and implementation methods for the remanufacturing. In order to accomplish these objectives, we introduced backgrounds of appearance and benefits of the remanufacturing.

As one of the developing countries in the world trade market, we have to apply the environmental concept at the development of a product for environmentally conscious manufacturing system(ECMS). Traditionally, production control model has been studied based on a new product manufacturing environment. However, ECMS such as a remanufacturing system should be developed and implemented for highly competitive environment in 21C. The objective of this study was to extend the research of production control model by applying it at the remanufacturing environment of ECMS and to test the applicability of current production control model at the remanufacturing environment by the simulation experimental study.

As production, distribution, consumption and processing increase with the development of industrial societies, the importance of resource depletion and environmental problems is increasing day by day. This has led to increased research and interest in remanufacturing that can satisfy both environmental and economic aspects. Currently, the remanufacturing industry is progressed in Korea with automobile parts with as the central figure, and it needs to be expanded into various areas. In this study, the failure type analysis and FMEA were performed on the hydraulic pumps used in construction and industrial sites for the development of the standard remanufacturing process plan, and the actual disassembly and reassembly process was carried out. Remanufacturing products were manufactured through the analysis contents and drawing process, performance tests were conducted in accordance with RS B1501 criteria to evaluate performance, and all of these products passed the test criteria.

Remanufacturing is one of the most important resource recycling technology in response to resource depletion and environmental pollution. Domestic remanufacturing industry don't invigorate compared to other advanced countries because of low price and reliability of remanufactured product. In this study, remanufactured hydraulic pump and solenoid valve were evaluated durability by accelerated life test. In order that standard remanufacturing process was developed by core analysis and failure mode and effect analysis. And cores were remanufactured by standard remanufacturing process. For accelerated life test, the evaluation item and criteria were deduced by results of FMEA, reliability standards and enterprise interior criteria. To evaluate durability of remanufactured product, the remanufactured hydraulic pump and solenoid valve were evaluated performance after accelerated life test and the results were satisfied with criteria. This study showed that remanufactured products have a similar level of durability to new products by definition of remanufacturing.
