This study aims to draw meaningful points from the Chang Po Go period in which Chang Po Go, who established an integrated logistics system while operating on the seas of three nations including Japan, China, and Shilla by taking Chunghaejin, Shilla, as a base of operations in the 9th century, and to discover the need for the construction of the logistics system in northeast Asia. Also, the study intends to propose strategies for contemporary application of the logistics system used during the Chang Po Go period, based on the modern logistics concept. As a result of specifically reviewing the lesson from the Chang Po Go period, which created a paradigm for a new cooperation in logistics, the leadership of the CEO, who is prepared with the long-term vision of Chang Po Go, the implementation of an integrated system for logistics activity, and the political support of the government for private companies, will initiate a bright outlook for the construction of the logistics system in northeast Asia, amid the growing need for cooperation in logistics among the three northeast Asian countries. In this era in which northeast Asia is emerging as the center of the world economy, the cooperative model in the logistics field, which transcended the border of Chang Po Go, who built a maritime logistics network in the 9th century, will help implement a cooperative logistics system in the northeast Asian region.

Refuse collection, one of important elements in reverse logistics, is an activity rendering recyclables or wastes and moving them to some points where further treatment is required. Among various decisions in the collection activity, we focus on network design, which is the problem of locating collection points as well as allocating refuses at demand points to collection points while satisfying the capacity restriction at each collection point. Here, the collection point is the place where recyclables or wastes near the point are gathered, and locating the collection points is done by selecting them from a given set of potential sites. The objective is to minimize the sum of fixed costs to open collection points and transportation costs to move refuses from demand points to collection points. An integer programming model is developed to represent the problem mathematically and due to the complexity of the problem, two types of heuristics, one with simultaneous and the others with separate location and allocation, are suggested. Computational experiments were done on test problems up to 500 potential sites, and the results are reported. In particular, some heuristics gave near optimal solutions for small-size test problems, i.e., 2% gaps in average from the optimal solution values.

The today many companies are tilting to enjoy the dominant position in the globalization of global market. The past business management is focus on the price and quality, but many companies are doing our utmost for customer satisfaction of various needs of customers. Therefore, The efficient logistics management is a core element in the competitiveness of company that respond more quickly and effectively to market. Now, The companies are building an integrated SCM(Supply Chain Management) system that is able to manage and operate procurement, production, distribution & logistics activity. Among the IT infra, The RFID technique is received special attention for this successful SCM System, continuously it is being researched and developed. Also, they recognize RFID techniques that offer various services at supply chain flow, create value of company. This study propose implications in other industry for biz model development and direction based on RFID in many industry through case study for development of the distribution logistics information system on using RFID.

To promote process effectiveness and efficiency, it is necessary that port logistics employ automated equipments for handling containers. There exists a system for automatically managing the container flow, called Control Module. However, it has limitation to assign the execution order to the machine and monitor the container flow in real time process. Business process management (BPM) provides a suitable and effective framework to address this problem including controlling and monitoring the flow of each container. Since the nature of container handling process is different with the common process in BPM that is conducted by human performer, it is necessary to adjust the BPM framework in the domain of port logistic management. This study presents a BPM framework corresponds with both human-based and machine-based activity to enhance the efficiency of port process flow including container flow. This framework is introduced as an integrated approach and mechanism of BPM application into the container handling system for the purpose of port logistics process automation.

This study is focused on the operation of truck with conscious for environmental logistics system to reduce empty truck movements, and to control running empty truck. With the logistics function, road transport represents the biggest environmental threat. Using nonrenewable natural resources, contributing to air and noise pollution, trucks are environmentally unfriendly. Any steps to reduce transport activity will help minimize negative impact. In particular, noxious emissions must be reduced, but in the long term more environmentally friendly vehicles are required.

Since 2000, e-commerce has been increased continuously in its quantity and quality. The growth of e-commerce has resulted in some diversities of distribution channels, and its characteristics of not-spot trading and limited market scale has urged the on-line market to play a role of assistance to off-line market. e-Commerce causes not only the flow of forward logistics, but also that of reverse logistics with every purchasing, which is a very critical factor to hesitate for consumers to purchase the products as well as increase the price of the products. Concern about the reverse logistics by sellers and buyers influences the level of price and purchasing activity of consumers. This study firstly is to lift the awareness of the efficient control of reverse logistics with reviewing the recent change of logistics environment and phenomena of reverse logistics. Secondly we find the factors generating the reverse logistics and look into its questions, and thirdly offer not only the ways to minimize the phenomena of reverse logistics, but also a efficient control system for reverse logistics. We additionally aim to contribute to prevent the price of the products from rising and raise the customers' satisfaction through minimizing the phase of reverse logistics.

One of the important factor for port selection is total handling charge(THC) of container terminal, and consequence of that the actual cost is vital for variation of THC. However, a great majority of the reported ABC applications have been limited to manufacturing and a little has been written on how the ABC approach can be used for logistics company especially for container terminal. This study proposes the applicable conceptual framework and cost management model based on Time-Driven Activity-Based Costing for container terminal.

The Korean logistics industry has grown with the development of domestic industries. The industry plays an important role in national and regional economic growth, and the government has continued policy efforts to foster the industry. This study analyzes the competitiveness of the regional logistics industry and its contribution to the regional economy. Location coefficients are used to analyze local specialization in each logistics industry. The value-added rate, GDP contribution, value-added induction coefficient, and net value-added income of regional logistics industries are analyzed using a regional input-output table. As a result, the logistics industry is found to have net value-added income and competitiveness in some regions, and there is no relationship between the location coefficient and the value-added contribution of the regional logistics industry. Seoul, Incheon, Gyeonggi, Busan, and Jeju have the competitiveness of each logistics industry. In addition, we identified the regions where the logistics infrastructure is well developed and those in which it needs to be supported. The regions where the logistics industry has developed require policies for making high value-added by logistics activity, and regions with insufficient growth need to support the development of the logistics industry by investing human resources and capital that can meet the local demand.
