전남 서남권은 동남권 지역에 이어 제 2의 조선산업 클러스터를 위한 산업기반 구축이 진행되고 있다. 전남 조선산업의 유연성과 불황기 대처능력을 제고하고 한국 및 전남권의 항만 개발에 따른 수리조선 수요에 대처하기 위해, 전라남도는 수리조선산업 진출을 검토하고 있는 바, 전남 지역의 수리조선 경쟁력을 분석하였다. 수리조선산업의 산업적 특정과 수리조선 수요 결정 요인을 고찰하고, 유럽, 싱가포르, 중동, 중국 등 주요 수리조선국 사례의 시사점을 토대로 전라남도의 입지 여건, 비용 및 기술력을 종합적으로 검토하였으며, 부산 등 동남권 지역의 주요 거점용 물론 전남 지역 내의 후보지에 대한 비교 분석을 수행하였다.

수리조선산업은 기술 및 노동집약적 산업으로 기계, 철강, 전기전자, 화학 등 연관산업에 대한 생산 유발효과 및 고용효과가 높은 산업이다. 또한 연계 산업에 대한 직접적인 생산증가 효과와 선원 체류에 따른 부가가치 증가 등의 부수효과를 함께 고려할 때 지역경제에 대한 기여도가 높은 산업적 역할을 수행하고 있으며, 특히 부산 경남 울산 지역은 세계 5위권 전후에 해당하는 해운물동량을 처리하는 입지조건과 신조선 분야 1위의 우수한 기술 및 노동력을 보유하고 있다. 이러한 긍정적인 측면에도 불구하고 여러 요인들로 인해 수리조선산업이 경쟁력이 확보되지 못하고 있는 실정이며, 2013년 들면서 부산항의 컨테이너 물동량 실적이 7위로 하락하고 있는 실정이다. 따라서 본 연구에서는 부산항을 중심으로 수리조선산업 공급망 관리를 위하여 정보화 네트워크 구축사례를 분석하고, 이를 통하여 수리조선산업 정보화 네트워크의 성공적인 구축 방안을 모색하고자 한다.

Since 2000's, Korea has became the world-leading shipbuilding country with the competitive technologies in design and production. And with the China's economic growth, the three economies (Korea, Japan and China) handle 30 percent of the world`s freight cargoes. Shipping industry of Korea has been also grown up to the top 10 of the world with the newly constructed large ports. In spite of the growing demand for ship repair in Korea, its competitiveness analysis has been insufficient. This paper present the competitiveness analysis of ship repair industry of Korea with the consideration of condition of location, repair cost and technological competitiveness.

The purpose of this research is to analyze the efficiency of the Chinese repair shipbuilding industry using a DEA model with 12 Chinese repair shipbuilding companies. Unlike preceding studies, this study has different research subjects as well as selected input and output variables. The research was conducted with competitive Chinese companies in the market. For the efficiency analysis, input variables included the number of technicians as well as facilities, and output variables were diversified with relevant factors using the number of repaired ships and service ranges as well as sales. The differences were analyzed by including only facilities as an input variable for the DEA model, and then both facilities and technicians. For inefficient DMUs, the strengths and weaknesses were analyzed by finding the causes through a reference group, which was developed into an efficient DMU. Moreover, public and private companies were separated to develop improvement measures.

조선기자재는 선박의 건조 및 수리에 사용되는 모든 기계와 자재류를 일컫는 것으로, 선종과 규모에 따라 다소 차이가 있으나 약460여종에 이르며 선박 건조원가의 55∼65%를 차지하고 있다. 선박부품인 조선기자재는 기능별로 나누어 금속제품, 화학제품, 용접재료, 주단제품으로 구성되는 선체부, 엔진을 포함하는 추진장치와 보조기계로 대별되는 기관부, 조타, 계선, 하역, 안전장비 및 거주설비 등의 의장부 및 동력, 배선, 조명, 항해통신, 제어장치 등으로 구성되는 전기ㆍ전자부로 분류된다. 특히 최근에는 방화ㆍ방재 설비로 대표되는 안전설비를 의장부에서 별도로 분류하기도 하며, 선박의 자동화 추세에 따라 전기와 전자부분을 분리하여 분류하기도 한다.(중략)

톨루엔, o-크실렌등의 유기용제는 도료공업 등의 혼합용제와 기계부품의 세척등에 많이 사용되고 있다. 그러나 이들 물질들은 공정상의 제조, 저장, 처리과정 및 취급과 사용 중에 부주의로 인한 밀폐구역에서의 누출로 폭발과 화재사고가 자주 발생하고 있다. 97년 5월 $\Delta$$\Delta$조선소에서 건조 중이던 선박 기관실의 선체 탱크내부 도장작업 중 화재ㆍ폭발이 발생하였으며, 97년 10월 $\square$$\square$조선소에서 수리중이던 유조선의 Tank 내부와 pipe line에 체류중인 가연성 증기가 인화되어 화재ㆍ폭발사고가 98년 6월 김해시 소재 00공업(주)에서 솔벤트로 공작기계 부품을 세척하던중 가연성 증기가 인화되어 화재가 발생하였다.

In this paper, we design a green supply chain (gSC) network model. For constructing the gSC network model, environmental and economic factors are taken into consideration in it. Environmental factor is to minimize the $CO_2$ emission amount emitted when transporting products or materials between each stage. For economic factor, the total cost which is composed of total transportation cost, total handling cost and total fixed cost is minimized. To minimize the environmental and economic factors simultaneously, a mathematical formulation is proposed and it is implemented in a genetic algorithm (GA) approach. In numerical experiment, some scales of the gSC network model is presented and its performance is analyzed using the GA approach. Finally, the efficiencies of the gSC network model and the GA approach are proved.

In this paper, a sustainable closed-loop supply chain (SCLSC) network model is proposed for domestic mobile phone industry. Economic, environmental and social factors are respectively considered for reinforcing the sustainability of the SCLSC network model. These three factors aim at minimizing total cost, minimizing total amount of CO₂ emission, and maximizing total social influence resulting from the establishment and operation of facilities at each stage of the SCLSC network model. Since they are used as each objective function in modeling, the SCLSC network model can be a multi-objective optimization problem. A mathematical formulation is used for representing the SCLSC network model and a hybrid meta-heuristic approach is proposed for efficiently solving it. In numerical experiment, the performance of the proposed hybrid meta-heuristic approach is compared with those of conventional meta-heuristic approaches using some scales of the SCLSC network model. Experimental results shows that the proposed hybrid meta-heuristic approach outperforms conventional meta-heuristic approaches.

This study proposes a supply chain network (SCN) model considering supply disruption in assembly industry. For supply disruption, supplier disruption and its route disruption are simultaneously taken into consideration in the SCN model. With the simultaneous consideration, the SCN model can achieve its flexibility and efficiency. A mathematical formulation is suggested for representing the SCN model, and a proposed hybrid genetic algorithm (pro-HGA) is used for implementing the mathematical formulation. In numerical experiment, the performance of the pro-HGA approach is compared with those of some conventional approaches using the SCN models with various scales, and a sensitivity analysis considering the change of the numbers of suppliers and backup routes is done. Experimental results show that the performances of the pro-HGA approach are superior to those of the conventional approaches, and the flexibility and efficiency of the SCN model considering supply disruption are proved. Finally, the significance of this study is summarized and a potential future research direction is mentioned in conclusion.
