  • The market competition of express package deliveries in Korea is severe because a large number of companies have entered into the market. This study thus suggests an approach to the reconfiguration of express service networks with respect to the strategy partnership of closing/keeping service centers among companies involved and the adjustments of their cutoff times. For this we propose an integer programming model and a genetic algorithm based solution procedure for allowing companies involved to maximize their incremental profit. An illustrative numerical example is presented to demonstrate the practicality and efficiency of the proposed model.

  • 최근의 IT기술의 발전과 더불어 지형 정보시스템(GIS, Geographical Information System)이 급격하게 발전되고 있으며 이를 이용한 위치기반의 물류시스템의 새로운 분야를 이루고 있다. 본 연구는 이러한 GIS를 이용하여 3차원의 지형정보를 구현하고 지금까지의 고려하지 못하였던 3차원 위치기반의 거리산정과 이를 물류시스템의 여러 분야에 활용할 수 있도록 SW를 개발하였다. 특히 본 연구에서는 물류시스템의 새로운 패러다임의 변화와 위치기반의 물류시스템의 예로 2차원의 GIS를 3차원의 GIS로 변환하였으며, 이를 3차원 거리산정하고, 이를 1) 거리산정모델, 및 2) 차량 운송계획 모델을 개발하고 이를 위한 SW를 개발하였으며 실제 물류시스템계획 문제에 응용한 사례를 보였다. 본 연구는 추후 보완 연구될 경우 실용적인 물류시스템의 방법으로 활용될 수 있을 것이다.

  • Companies are reluctant to disclose information because of trade secret and corporate identity For the same reasons, logistics companies do not want to operate in the form of a community In urban areas, the loading of vehicles is 100% as the quantity of goods transported is too much. In mountain areas, however, the load condition of the vehicle is not 100% because of the low quantity of goods transported Therefore, the transportation costs will increase as the cost of transport increase, the competitiveness of firms will also decline In this paper, we studied a simulation to measure driving time and volume of cargo according to the change of the quantity of goods transported in the mountain area According to the research results, we got a conclusion that the proposed method makes the operation time be less and the volume of cargo increase compared with the existing operation method.

  • This paper deals with the application and effects of MES for H automobile plant in China. There existed the production planning and the different work order in PL painting plant, but we can simultaneously prepare the painting parts and parts delivery and assembly according to painting color by introducing MES. We can respond the change of production planning and operate integratively the PL painting, parts storage and parts delivery and then we can results in reasonable logistics. We obtained the exact production information, correct work order, precise delivery order. We obtained not only the improvement of logistics but also the reduction of inventory.

  • Recently, ordinary mail is decreasing continuously by the development of ICT (Information and Communications Technology) including E-mail, messenger service, and etc. On the contrary, parcel post is increasing by the increase of online shopping, home shopping, and etc. Aside from these changes, the demand for various mail acceptance and delivery means is increasing with the increase of single households and dual-income couples. To overcome these environmental changes, Korea Post installs unmanned post offices which are composed of various unmanned mail acceptance and delivery postal systems. In this paper, we propose the methodological approach for the site selection of unmanned post office among the existing post offices and the installation standard of unmanned postal system considering the operation cost by the mail volume.

  • Compound logistics is a service aimed to enhance logistics efficiency by supporting that shippers and consigners jointly use logistics facilities. Many of these services have taken place both domestically and internationally, but the joint logistics services for e-commerce have not been spread yet, since the number of the parcels that the consigners transact business is usually small. As one of meaningful ways to improve utilization of compound logistics, we propose a brokerage service for shipper and consigners based on the hybrid recommendation system using very well-known classification and clustering methods. The existing recommendation system has drawn a relatively low satisfaction as it brought about one-to-one matches between consignors and logistics vendors in that such matching constrains choice range of the users to one-to-one matching each other. However, the implemented hybrid recommendation system based brokerage agent service system can provide multiple choice options to mutual users with descending ranks, which is a result of the recommendation considering transaction preferences of the users. In addition, we applied feature selection methods in order to avoid inducing a meaningless large size recommendation model and reduce a simple model. Finally, we implemented the hybrid recommendation system based brokerage agent service system that shippers and consigners can join, which is the system having capability previously described functions such as feature selection and recommendation. As a result, it turns out that the proposed hybrid recommendation based brokerage service system showed the enhanced efficiency with respect to logistics management, compared to the existing one by reporting two round simulation results.

  • The objective of this study is to propose an operation management strategy for the connectivity which are the designated and managed in sector of the transportation and logistics on the national critical infrastructures. The industrial structure is becoming advanced. The national critical infrastructure managed by the shows forms of the cooperative connection and collaborative R&D. Also, in-depth and specific analysis for the disaster safety budget are implemented to consideration for the R&D life cycle. The government responsibility are expanded comprehensively. Needs are exchanging life styles by the economic and safety demands. At this trends, this study encourage facility maintenance and scientific management to the public service. Throughout the result of this study, national critical infrastructure are implementing for protection plan of the sustainable maintenance and management. And, we have to prepare and implement for the consideration of the characteristics through comprehensive guidelines. This study contributes to the disaster and safety management by proposed an operation strategy of the cooperative connection in the sector of transportation and logistic sector on the national critical infrastructure.

  • In this paper, we analyze process of implementing and successful enabler of Postal Logistics Integrated Information Systems(PostNet) through a case study on Korea Post. PostNet was integrated by considering contingently organizational integration (organizational structure redesign), strategical integration (business process reengineering), and technical integration(data integration, application integration, and integrated platform implementation). And also integration was implemented for supporting three aspects. PostNet has implication for advanced integration with business mission and operational efficiency by comparing integration with physical level and hardware level. Korea Post has the biggest logistics network, organization, and service in logistics industry area. The results of this paper will suggest theoretical framework for the future information system integration, and will be utilized as a practical guideline for the information system integration.

  • On a conceptual point of SCM, as a order of development, physical distribution, logistics management, basic supply chain management and advanced supply chain management etc. they are magnifying gradually, confusing with information and analysis techniques which seems possible. But on executing, it has a lot of problems because it is so complex and wide, so the enterprise which knows necessity of SCM, they don't have a total execution solution. On this paper, we will focus a proposal of alternatives with reasonableness of manufacturing and making a profit of sales department like most of enterprises to overcome carelessness and unready strategy of investment. And we will find a element through a analysis of cases, a statistical method of effective SCM, and actual survey to propose a alternative proposal. And, we will prove the facts that it could be a guiding company which has a ability of cooperation with entities through the founding of supply chain.
