항만물류 산업에서는 ebXML이 부분적으로 이루어지고 있지만, 도메인 단위의 ebXML이 적응된 것은 거의 없는 실정이며, XML/EDI, ebXML 정보 시스템에 관한 연구가 진행되었지만 업무 전반에 적용되지 않고 있으며, 또한 항만물류 산업의 등록저장소가 따로 없는 실정이다. ebXML 기반의 선용품 SCM(Supply Chain Management) 시스템을 통해 각 업체간의 재고파악이 실시간으로 가능하게 되며, 이를 통해 각 업체간의 정보 공유는 물론 비용절감 면에서도 큰 효과를 거둘 수 있다. 본 논문에서는 SCM의 기본개념과 항만물류업무인 선용품 거래의 흐름을 분석하여, 차세대 전자상거래의 기반 구조가 될 ebXML 프레임워크에 기반한 선용품 SCM 시스템을 개발한 방법을 소개한다.

SCM(Supply Chain Management)은 초기에 생산의 효율성 증대를 위해 생산 계획에 초점을 둔 제품으로 발전하였으나, 최근에는 수요자 중심으로의 비즈니스 패러다임 변화, 프로세스 간 상호연계 강화, 수요의 다양성 및 변동성 증가 등의 환경이 변화하면서 지능적인 SCM이 요구되고 있다. 지능적인 SCM은 IoT, 빅데이터, 인공지능 등의 기술을 활용하여 공급 사슬 전체에 대한 자동화, 자율화, 연결성을 보장하는 것을 강조하고 있다. 따라서 본 논문에서는 급변하는 비즈니스 환경변화에 대응하여 공급 사슬 최적화를 달성하기 위해 IoT와 빅데이터 기반의 SCM 시스템에 관하여 연구하였다.

Magneto-Rheological (MR) fluid is suspension of fine magnetic particles in a liquid carrier such as silicon oil or water. MR fluid exhibits solid-like mechanical behavior into chain or clusters with high yield stress when magnetic field is applied to the particles. The response of MR fluids is very quick and reversible after removal of the field. MR Fluids have high yield stress (up to 5kPs) and operate in low voltage power supply. Recently, MR damper using MR fluids was open used in vibration control system such as structural devices, seat vibration controllers and helicopter rotor systems, but it is too big in size and heavy. Therefore, it is not appreciate to rehabilitation devices such as prosthetic limbs.

최근의 정보기술의 급속한 발전과 더불어 대형사업의 성공 및 실패할 확률을 고려한 프로젝트 위험분석 연구가 널리 연구되고 있다. 특히 정보시스템을 기반으로 발전되고 있는 SCM(Supply Chain Management)의 구축사업은 복잡하고 대형프로젝트들로서 계획 초기부터 운영단계에 이르기까지 사업의 성공 및 실패할 확률을 예측함은 매우 중요하다. 본 연구에서는 이러한 SCM구축사업의 위험분석을 위하여 다 속성(Multi-Attribute)구조를 가지는 분석 방법과, 구축사업의 비용, 기간 및 고객 서비스능력 등을 고려한 위험 분석모델을 개발하였으며, 두 가지 방법을 사용하였다. : 1) AHP 방법을 이용한 가중치 방법, 2) SCM 네트웍을 구축하고 방법을 사용하였다. 또한 이를 위한 전산프로그램을 개발하고 실례를 들고 그 결과를 보였다.

For the B2B e-commerce and SCM (Supply Chain Management), standardization of electronic catalogue that contains product and business data is important. Especially, standardization of hierarchies that is required for categorization, and standardization of product properties are difficult and costly to maintain. The ability of searching for items and data in databases is critical for successful e-commerce system. This paper introduces the data dictionary of PUB (ISO 13584) part 42 which can establish the standard of product data. The method is applied to develop the data dictionary of automotive parts.

The vehicle routing problem with time windows (VRPTW) is an important problem in third party logistics and supply chain management. We extend the VRPTW to the VRPTW with overtime and outsourcing vehicles (VRPTWOV) which allows the overtime of drivers and the possibility of using outsourcing vehicles. This problem can be applied to third party logistics companies for managing central distributor-local distributors, local distributor-retailers (or customers), and a manufacturer. We develop a mixed integer programming model and a genetic algorithm. Computational results demonstrate the efficiency of the developed genetic algorithm. We also develop a decision support system based on this genetic algorithm.

Recently, innovative medical services are fast emerging, which include customized medical services based on bio-informatics, composition of cure and well-being exploiting ubiquitous technology, hospital supply chain management using RFID, and so forth. However, conventional approaches for new service development hardly give us systematic model to analyze and produce creative medical services. Because most of them are static and concentrate on microscopic tools or techniques. Thus, it is highly desirable to suggest an integrative framework to organize the whole transformation process from technology to medical service. The objective of this study is to propose a medical service engineering model based on the dynamic innovation theory. The proposed model contains objectives of service system, strategies of hospital, stages, activities required to deal with medical service life cycle, which incorporates the acquisition of new technology, transformation to the product, penetration into market, and adoption of consumers. In addition, the usefulness and applicability of the newly proposed model are provided using catholic medical center example.

The firms aim to acquire services and costs advantage from logistics outsourcing strategy. But it is very important to select optimum service provider. A checklist of the criteria for the evaluation of service providers follows : service quality, low cost, logistics information system, service network, financial stability, investments in plant and equipment, management attitude and lookout for the future strategic fit, cultural and psychological barriers etc. Also, a 8-step implement of logistics outsourcing strategy will be of help for maximizing benefits of logistics outsourcing. It follows : 1-step : logistics environment analysis, 2-step : check service provider availability, 3-step : logistics outsourcing determinant analysis, 4-step : select of optimum service provider, 5-step : contract with optimum service provider, 6-step : identify of remaining barriers, 7-step : performance of logistics outsourcing, 8-step : evaluation.

Radio frequency identification(RFID) is a system of technology that transmits digitally coded identity information in the form of a unique serial number of an object or person wirelessly, using radio waves. The primary use of RFID has been in asset tracking. This makes it highly useful across various industries for effective and efficient conduct of different business processes like supply chain management (SCM). As the use of RFID expands, the use of this technology is observed in such industries as transportation, traffic payment, hospital and medical care, education, and retail. Although this technology offers immense potential, it faces multifarious roadblocks, particularly in developing countries like India. Under this backdrop, this paper attempts to present an overview of the use and application RFID technology in India with a highlight on business-ecosystem for RFID in India. We also present various technical and non-technical challenges in the implementation of RFID in India.
