본 연구는 공급자(supplier), 중간분배자(retailer/distributor) 그리고 고객(customer)으로 구성된 2 단계 공급사슬을 대상으로 공급자가 수요 증대를 목적으로 중간분배자에게 일정기간 동안 제품대금에 대한 지불 연기를 허용한다는 가정 하에 중간분배자의 최적 재고정책 결정을 위한 재고 모형을 다루었다. 소비성 상품의 경우, 고객의 수요는 일반적으로 상품 진열대에 진열되어있는 상품의 재고량에 많은 영향을 받는 것으로 알려져 있다.

This paper studies that б values(10, 20, 50)and ρ values (-0.6, -0.3, 0.0, 0.3, 0.6) affect the total inventory cost of a supply chain and order fill rate when the market demand process follows a general auto-correlated AR(1) process without seasonality.

전 세계적으로 대량생산, 대량소비의 결과로 발생된 폐기물의 감량과 재활용을 확대하려는 법적 규제가 강화되고 있다. 그와 동시에 제조업도 환경 친화적으로 변모하고 있으며 이와 병행하여 공급사슬도 자원 순환형으로 변화하고 있다. 공급사슬의 분석, 설계, 운영, 통제 등의 경영관 리 기법도 변화를 거듭하고 있는데 과거의 환경산업이나 재제조산업은 정부의 규제법규를 준수하는 범위 내에서 비용 최소화의 목적으로 진행되었으나 현재에는 적극적으로 사용 후 회수된 재활 용 제품의 부가가치를 회복시켜 수익을 창조하는 수익사업으로 여겨지고 있다. 본 논문에서는 EU 국가와 미국 등 선진국에서 역공급사슬 개념의 형성과정과 순환형 공급사슬이 되기까지의 변천과정 또한 그 과정에서 발생된 중요한 개념들을 살펴보고 이와 관련하여 경영, 경제, 산업공학과 관련한 선진국에서의 연구 분야에 대하여 조사하여 앞으로의 연구 방향을 모색해 보고자한다.

In reality, distribution planning for a supply chain is established using a certain probabilistic distribution estimated by forecasting. However, in general, the demands used for an actual distribution planning are of deterministic value, a single value for each of periods. Because of this reason the final result of a planning has to be a single value for each period. Unfortunately, it is very difficult to estimate a single value due to the inherent uncertainty in the probabilistic distribution of customer demand. The issue addressed in this paper is the selection of single demand value among of the distributed demand estimations for a period to be used in the distribution planning. This paper proposes an efficient demand selection scheme for minimizing total inventory costs while satisfying target service level under the various experimental conditions.

This paper was concerned about design and implementation of supply chain management for auto-part company by adopting a UML(Unified Modeling Language). The part of SCM and e-business have interested by larger company, researcher and academic professor. There has been known about a little implementing SCM and it's initiatives for SME(small-medium sized enterprise). We, in this paper, dealt with design and implementing the SCM on supply chain auto part SMEs. The UML is a standard language for specifying, visualizing, constructing, and documenting the artifacts of software systems. It simplifies the complex process of software design, making a blueprint for the SCM implementation. In this paper, we also adopt some methods for the systematic system analysis, design, and implementation by applying UML to a SCM system.

  This study was concerned about mobile web-service of a VMI in the SCM system. The VMI would be a main module part of the SCM and regarded as very important thing on supply chain. Therefore, it was essential to react in real time of materials production

  Recently, youth unemployment is not a mere economic problem in Korea. It could be developed into a serious social problem. It has been long since youth unemployment rate was more than double in total unemployment rate, which stood at 3.5 percent in 2005

Recently, youth unemployment is not a mere economic problem. It could be develop into a serious social problem. According to data released by the National Statistical Office that the jobless rate for younger koreans aged between 15 and 29 reached 8 percent in 2005, which was more than double in total unemployment rate. Unemployment among young people has been getting worse since the foreign exchange crisis. Hence, this paper examines the status and causes of the youth unemployment problem and studies the possibility to apply the Demand-Supply Chain Management to the problem.

The purpose of implementing supply chain management is quick decision making and effective execution on the affairs of management by sharing information. It is critical that companies are needed to innovating supply chain process in oder to maintain their international competitiveness. The improvement of supply chain process makes the S company to provide better products than any other companies do. This case study investigates the introduction and strategy development of supply chain management at the S company. The goal of this study is to develop supply chain management strategies by reviewing best practices of advanced global enterprises and to find key performance indicators suitable for the S company. Four focused factors for the establishment of basic supply chain process are organizing task force team, changing to process type organization, definite assignment of role and responsibility, and constructing information system.

Both supply chain management and safety management contribute to strengthening a company's competitiveness. However, there is no previous research that considers supply chain management and safety management simultaneously The objective of this research is to study on application of safety management to supply chain. In this paper, the concept of supply chain safety management is defined. Based on the concept of supply chain safety management, supply chain safety management model is developed that consists of supply safety management, production safety management, storage safety management, and distribution safety management. In order to apply supply chain safety management, a methodology is developed that consists of four phases. Applying the supply chain safety management model, it is expected a company to lower cost as well as to raise customer satisfaction level.

This research is focused on the development of the performance measuring system for the supply chain. Although there are previous researches about this, they has the limit to measuring the performance. This is oriented that each measuring system deal with a certain level like strategic level, tactical level, or operational level of the supply chain. However, it is necessary to measure the performance in multiple levels collectively. A new performance measuring system using key performance indicators with integrating SCOR-Model(Supply Chain Operations Reference Model) with Balanced Scorecard(BSC) is proposed in this research. Since SCOR-Model and BSC are mainly dealt with strategic level and operational level, the proposed system can overcome the limit of previous researches. Then, this methodology is used to develop the real time performance measuring system.
