Extraction of Cause Factors to Enhance the Competition of Ship Management Industry Considering Ship’s Lifecycle based an Intuitionistic Fuzzy DEMATEL&ISM
최근 부산시는 선박관리산업의 관심을 증대시키고, 경쟁력을 강화 및 지원하기 위한 조례를 제정하였다. 본 연구는 직관적퍼지 DEMATEL&ISM법을 이용하여 선박관리산업 경쟁력 강화의 원인요인을 도출하는데 있다. 이를 위해 먼저 선박관리산업발전법에 명시된 내용을 기반으로 8개의 요인을 추출한다. 두번째는 직관적 퍼지수를 표준퍼지수를 이용하여 크리습 수로 변환한다. 세번째는 DEMATEL 법을 이용하여 영향관계를 분석하고 ISM법을 이용하여 요인에 대해 우선순위를 결정한다. 영향관계 분석결과 원인요인은 기술적 선박관리 역량 제고, 육상관리인력 전문성 제고, 한국선원인력 자질향상으로 나타났다. ISM법에 의한 우선순위는 한국선원 자질향상, 육상관리 인력 전문성 제고, 기술적 선박관리 역량제고, 상업적 선박관리 역량 제고, 종합정보시스템구축 = 선원 근로조건 및 고용환경 개선 = 금융 등 지원 = 외국인 선원 공급 강화 등의 순으로 나타났다. 따라서 전체 영역에서 원인요인이며 우선순위가 높은 상위 3개의 요인에 대해 우선적인 정책추진이 필요하다.
In those day, the Busan local government had instituted a rule to support and enhance competition as well as improve respect for the ship management industry. This study aims to extract the cause factors to enhance such competition using intuitionistic decision making trial and evaluation laboratory (DEMATEL) and interpretive structural modeling (ISM) methods. First, eight factors were extracted from the specifications in the Ship Management Industry Development Act. Second, the intuitionistic fuzzy number was converted to a crisp number using the standard fuzzy number. Third, the influence relationship was analyzed using DEMATEL, and the priority ranks for the factors are determined using ISM. From the results of the impact relationship analysis, the three main cause factors were determined as improvement of technical ship management capability, improvement of expertise of manpower for onshore management, and improvement of the quality of the Korean seafarer. The priorities under the ISM method, in descending order, were as follows: improvement of the quality of Korean seafarers, improvement of professionalism among the manpower for shore management, improvement of technical ship management capability, improvement of commercial ship management capability, establishment of a comprehensive information system, improvement of the working conditions and employment environment for seafarers, financial support such as overseas orders, and strengthening the availability of foreign seafarers. Therefore, it is necessary to prioritize policy promotion based on these factors, especially the top three, as these have the highest impact.
