  • 지속적인 유가 상승과 탄소배출 규제 강화는 기업들로 하여금 높은 경쟁력을 가지도록 요구한다. 따라서 고객 서비스 증대와 비용절감을 위해 효율적인 물류시스템을 구축하고 운영하는 것에 많은 노력을 기울이고 있으며 경쟁력을 가지는 물류단지의 필요성이 증대되고 있는 실정이다. 이러한 물류도시를 구축하기 위해서는 적절한 정책과 화물수송 공동화를 통한 물류시스템이 필요하다. 특히, 단지내 물류시스템의 체계구축을 통한 효율적인 운영은 저비용 친환경적인 측면에서 매우 중요하다. 따라서 본 연구에서는 물류단지내 효율적 운송을 위한 물류네트워크를 운영 모델을 제시하고 특히 운송 다단화 단계를 통해 문제에 접근하고자 한다.

  • 본 연구에서는 재사용 가능한 제품을 대상으로 순방향물류(Forward logistics)에서 부터 역방향물류(Reverse logistics)에 이르기까지 전체 물류비용과 수요와 회수에 따른 제조업자에서의 재고관리, 재사용을 위한 과정에서 발생하는 청소공정비용 및 폐기비용을 고려한 재사용 네트워크 모델(Reusable network model)을 제안한다. 제안 모델의 유효성을 검증하기 위하여 최적화 기법 중 하나인 유전자 알고리즘(Genetic algorithm: GA)을 이용한다. 파라미터가 해(Solution)에 미치는 영향을 알아보기 위해서 세 가지 파라미터 조건에서 우선 순위형 GA(Priority-based GA: priGA)와, 각 세대(Generation)마다 파라미터가 조정되는 개량형 하이브리드 GA(Modified hybrid genetic algorithm: mhGA)를 사이즈가 다른 4가지 예제에 적용하여 시뮬레이션을 실시한다.

  • East Asia has played an important role in the economic and social development in the Asian pacific region and in the global arena. In the region the impact of companies centralizing their logistics activities around a few distribution centers has already led some leading ports such as Singapore, Hong Kong to transform and expand their functions and business activities to provide port users with value added logistics services. Other ports in the region also have an important part to play in the total logistics Chain. In these environments, the maritime activities of Jang BoGo, who was the maritime king of the commercial maritime empire in East Asia in the 9th century, give many implications to the international logistics network strategy that Korea has to take in order to become a power of International Logistics. Though the trading and economic environments at that time may be quite different from today, the super-national maritime management pattern that Jang Bo-go, founder of the Northeast Asian maritime trading kingdom devised, gives us many implications in the global trading and economic environments, in the respects of overseas direct investment and international logistics. Accordingly, the paper aims to examine the establishment of hub port in Northeast Asia, modelled after the maritime network management strategy of Jang BoGo.

  • Due to limitation of resources and increasing concerns about environment, reverse logistics has received growing attention in recent years. In this paper, we propose three types of reverse logistics networks based on reuse of returnable containers, materials recycling process and remanufacturing for parts reuse. First, the sender in the re-usable item network supplies containers for the recipient and orders either new containers from external supplier or returnable containers cleaned from the container depot. Second, the recycling center in the proposed recycling network collects either end of life products from customer or faulty goods from manufacturer, collected products are dismantled into materials and materials go into recycling process. Finally, the manufacturer in the proposed remanufacturing network has two alternatives for supplying parts: either ordering the required parts to external supplier or overhauling disassembled parts and bringing them back 'as new' conditions. In this product recovery environment, we build optimal order quantity models to minimize the total logistics costs related to reverse logistics network. The validity of the proposed model is investigated through comprehensive computational experiments.

  • EPC(Electronic Product Code) 기반의 물류정보 네트워크인 EPCglobal 네트워크는 다수 기업이 유기적으로 결합하여 이루어지는 개방형으로 발전하고 있다. EPC-global 네트워크에서는 물류정보가 분산되어 있고, 그 양이 방대하기 때문에 효과적으로 정보를 관리하기 위한 노력이 요구된다. EPCglobal에서는 세계적인 연구소 및 업체들이 모여 RFID/EPC 기반 물류 네트워크에서의 EPC Information Service(EPCIS), Object Naming Service(ONS) 등의 구조에 대한 표준을 정의하고 관련 표준에 대한 연구를 계속하고 있다. 본 논문에서는 EPCIS와 EPC Discovery Service(EPCDS)에 대해 표준에서 요구하는 기능과 역할을 충족시키고, 나아가 더욱 효율적인 물류정보 관리를 위해 확장된 기능의 EPCIS와 EPCDS를 제안한다.

  • Many Firms consider the application of a cross-docking system to reduce inventory and lead-time. However, most studies mainly concentrate on the design of a cross-docking system. This study presents the method that selects the cross-docking center under the existing logistics network. Describing the operation environment to apply the cross-docking system, the selection criteria of the cross-docking center, and the main constraints of transportation planning under the environment of multi-level logistics network, we define the selection problem of the cross-docking center applied to a logistics field. We also define the simulation model that can analyze variously the cross-docking volume and develop the selection methodology of the cross-docking center. The simulation model presents the algorithm and influence factors of the cross-docking system, the decision criteria of the system, policy parameter, and input data. In addition, this study analyzes the effect of increasing the number of simultaneous receiving and shipping docks, and the efficiency of the overnight transportation and cross-docking by evaluating each scenario after simulating the scenarios with the practical data of the logistics field.

  • This study is to investigate global logistics strategies of Korean electronics companies. in terms of service parts. According to the survey, Korean electronics companies were pursuing multi-level global logistics network such as global, continental, national, regional and service center echelon for improving the efficiency of service parts global logistics. Especially there was a tendency of developing new continental distribution centers. And the companies were exploiting efficiency through inventory control by multi-level echelon, demand forecasting by the product life cycle and supply and service lead time management. But there were some insufficient factors for the efficiency of global logistics operation at the construction of worldwide real time logistics information system and pursuit of the efficiency on the whole network including subcontractors. For the future competitive advantage of the Korean electronics companies, the following are suggested: 1) the establishment of arranged logistics channel adjusting each company's global strategy, 2) the construction of worldwide real time logistics information system, 3) the reengineering of all logistics procedures such as order processing, shipping, inventory control, etc., 4) the enhancement of the ratio of the supply from the external companies and the internal manufacturing subsidiaries at each continent, 5) and the pursuit of operational internalization of external subcontractors.

  • At present, on increasing to use a computer network and internet network, Internet Trade has been rapidly created and developed in international Electronic Commerce. However, Internet Trade has not been continued to grow up without supporting by a efficient Logistics System. Because it is very important to delivery contract commodities to consumer with speedy, accurate, steady, convenient services. International Logistics System is consisted of demand forecasting, order processing, packing, labeling, shipping documentation and consumer service into three distant phases of transaction, distribution and payment. International Logistics System can be done more efficiently and effectively by using Internet Logistics System. Therefore it is very important to implementing a efficient Internet Logistics System.
