최근 기업활동의 자재구매, 제조, 보관 및 운동, 유통/판매까지 포함한 공급체인 전체에 대한 통합관리(SCM: Supply Chain Management)가 중요한 과제로 부각되고 있다. 특히 기업의 글로벌화가 진행되고 고객요구가 다양화되면서, 고객 만족을 위한 제품의 Customization이 중요시되고 있다. 대부분의 다품종 주문생산형 장치산업에서는 다양한 제품을 제한된 라인에서 주어진 납기 내에 생산해야 한다. 대부분의 고객은 상당기간의 사용량을 한꺼번에 주문하고, 이를 필요시에 소량씩 출하하고, 주요 고객들은 생산일정 변경에 따른 긴급물량을 요구하며, 이에 따라 많은 고객에 대한 납기가 늦어지는 실정이다.본 연구에서는 고객과 납기를 협의하여 확정하고, 이 납기에 반드시 납품하는 납기확약(CTP: Capable to Promise) 기능을 도입하는 다품종 주문생산형 장치산업에서 적용 가능한 다양한 납기확약(CTP) 운영정책의 대안을 제시하고, 이들 성과를 컴퓨터 시뮬레이션으로 평가한다.

RFID(Radio Frequency Identification)를 이용하면 제품에 대한 실시간 파악이 가능하다. RFID는 IT 산업의 대안으로 평가되고 있고, 생산물류 뿐만 아니라 SCM의 재고를 관리하는 데에 있어서도 재고통재 및 관리를 효율적으로 할 수 있다. 또한 품질보증의 기능을 하고 제품에 대한 로트 추적이나 생산과정을 파악할 수 있어 문제점에 대한 재발방지 및 개선에 대한 역할이 가능해 진다. 실시간으로 재고를 통제 및 관리함으로써 보다 효율적인 생산지시 시스템을 구축할 수 있다. 이외에도 IE분야인 공정관리, 작업관리, 설비관리, 유통관리, 유통관리 등에도 적용이 가능하며, 재해의 위험요소를 원천적으로 방지하는 RFID 안전시스템에도 적용할 수 있다. 본 연구는 RFID의 적용 및 활동방안 대해 연구를 통해 새로운 기술환경에서 IE 및 산업안전 분야 등에 활용하고 역할과 책임을 다하고자 하기 위함이다.

Now, the Korean footwear industry needs the concrete enhancement of its competitive edge for regaining of its previous well known reputation. For this purpose, this study emphasizes the cooperation between the members through the supply chain of Korean footwear industry, as a c-SCM(Collaborative Supply Chain Management) by aid of information system. The key issue will be how well to coordinate operations flow not only through internal process stages, but also through entire external supply chain stages. In other words, the target goal must be the system optimization through the entire supply chain beyond the local optimization of internal supply chain process. We, at first, analyze the traditional structure of supply chain in Korean footwear industry and find out critical problems, and then, we develop the collaborative information framework in conjunction with several collaborative process modules. The suggested collaborative production & supply planning system was designed for sharing information and it is based on ebXML(electronic business eXtensible Markup Language) framework. In this way, the enhancement of the efficiency and competitiveness can be expected through the synergy effect of coordination of information and material flow, the reduction of lead times, and production costs.

The purpose of this paper is to suggest a plan on succeeding together-Busan New Port & BJFEZ(that is, port hinterland development). This study deals with the terms of three connection growth factors which are a firm's subjective factors, a industrial environment factors, and a governmental policy factors. According to analysis results of the factors, a firm's subjective factors(4.11 score) are scored the most ones of connection growth factors of Busan New Port & BJFEZ, to be compared with a governmental policy factors(4.01 score). with a industrial environment factors(3.92 score). Therefore, first of all, Busan New Port & BJFEZ have to promote connection growth through as follows, a firm's subjective factors : (1) to procure competitiveness through establishment of connection growth model, (2) to promote concentrated marketing strategy & market response ability, (3) speedy meeting to customer's needs, (4) to procure reliability of Busan New Port & BJFEZ. And, the next, Busan New Port & BJFEZ have to promote connection growth through considering a governmental policy factors, a industrial environment factors.

공급체인관리(Supply Chain Management)는 단순히 물질의 흐름관리뿐만 아니라 제품의 생산, 공급, 유통 등 다양하고 복잡한 활동들의 물질 및 정보 흐름의 통합이라고 할 수 있다. 그러므로 각 구성원간의 긴밀한 협력과 공동작업을 위해서는 원활한 정보 수집 및 응답이 요구된다. 하지만 기존 시스템은 비이동성 에이전트 개념으로 네트워크의 오버헤드나 혹은 접속 단절 상황에서 작업 수행이 불가능하여 구성원간의 정보 수집과 응답이 실제 업무 처리에 지연이 발생되므로 생산에서 판매까지의 리드타임이 길어지게 되고 채찍효과(Bullwhip Effect)가 더욱 크게 나타난다. 따라서 본 논문에서는 구성원간 협력과 공동작업을 위해 효율적으로 처리되어야 할 정보 수집 및 응답을 대상으로 하는 효율적 다중 응답을 위한 이동 에이전트 시스템을 설계한다. 제안시스템은 기존 시스템의 문제 해결을 위해 이동 에이전트와 객체 복제 메커니즘을 제시하며, 또한 각 구성원 시스템의 투명성을 위해 네이밍 서비스의 구성 방법과 등록된 구성원 시스템 객체의 객체 참조자 정보에 따라 복제된 이동 에이전트가 각 구성원 시스템으로 이주하는 이주 방식과 이주 후, 개별적인 작업 수행 결과를 해당 각 구성원 시스템에 제공하는 다중 응답 시나리오를 제시한다.

The purpose of this paper is examine the existing relations structure and IT use for collaboration activities on supply chain and their impacts on the performance of supply chain. This study made a design of the research model that was further constructed by integrating the relationship structure, IT exploration, IT exploitation, supply chain collaboration, absorptive capacity, and knowledge creation, efficiency and efficient. The survey data were collected from 378 companies, where firms are facing increased global competitive pressure and heavily utilize SCM to retain their competitive advantages. The authors validated a measurement model with structural equation modelling and tested eight hypotheses. As a result, the absorptive capacity was closely related to trust, IT exploitation and IT exploration, but supply chain collaboration. Examining the effect of supply chain collaboration with two types of absorptive capacity, the authors found positive effect on potential absorptive capacity, but a non-significant effect on realized absorptive capacity. This finding suggests that the improving performance of supply chain not only is related to the relations structure and IT use on supply chain, but also is closely related to the absorptive capacity.

Demand forecasting is the basis of management activities including marketing strategy. Especially, the demand of a part is remarkably important in supply chain management (SCM). In the fields of various industries, the part demand usually has the intermittent characteristic. The intermittent characteristic implies a phenomenon that there frequently occurs zero demands. In the intermittent demands, non-zero demands have large variance and their appearances also have stochastic nature. Accordingly, in the intermittent demand forecasting, it is inappropriate to apply the traditional time series models and/or cause-effect methods such as linear regression; they cannot describe the behaviors of intermittent demand. Markov bootstrap method was developed to forecast the intermittent demand. It assumes that first-order autocorrelation and independence of lead time demands. To release the assumption of independent lead time demands, this paper proposes a modified bootstrap method. The method produces the pseudo data having the characteristics of historical data approximately. A numerical example for real data will be provided as a case study.
