Ever since the computer came into being in early 20th century, rapid development of the information technology has led to the opening of the ubiquitous age where daily works can be done anywhere, anytime, and with any devices. The information technology has drawn attention from Customs around the world as a key means to fulfill multi-faced responsibilities of strengthening regional cooperation in the international trade, simplifying clearance procedures, expediting logistics flow, and ensuring security in the global supply chain. Korea Customs Service, which began the informatization effort by establishing the electronic export declaration system in 1992, completed the 100% electronic clearance system in 2000, with a number of countries now conducting benchmarking studies on the successful use of IT by KCS. This paper is to address the changes brought to the Customs administration in the information age, the progress and achievement of the Customs informatization as a proactive strategy to deal with the changing environment, and the exportation to overseas administration of the e-clearance system of KCS which strives to become the global leader of Customs informatization. The exportation. in particular, will not only lead to increased foreign currency earnings and shared know how, but also create an opportunity to reflect Korea's system in the standardization of Customs procedures around the world.

The volume of parcel delivery is steadily increasing with the rapid growth of the global online e-commerce market. However, a large amount of packaging materials used for these parcel delivery is finally causing environmental problems as waste. In this study, we have taken a pilot test on the returnable parcel delivery packaging & service, which is one of various ways to reduce the generation of the distribution packaging waste raised by e-commerce-based parcel delivery. For the purpose of this project, we made 300 boxes of returnable & foldable delivery packaging(415 mm × 280 mm × 160 mm) and have cooperated with e-commerce company(CJ ENM) & logistics company(LogisAll). Consequently, about 50% of the delivered packages was returned because of the lack of consumer's understanding on the returnable packaging system. We finally have suggested the policy strategy to get over problems derived from the experiment, like the retrieval rate and cost of the returnable packaging, economic efficiency and so on.

This paper considers the value of warehousing contract under probabilistic demands. We consider a supply chain consisting of a supplier, a retailer and its third-party warehousing partner who provides the warehousing service to the retailer through an outsourcing contract. A typical contract is specified by initial space commitment and modification schedule. The retailer decides the order quantity for the supplier and space commitment for the outsourcing contract. Since there is close relationship between order quantity and space commitment to minimize the total cost including ordering cost, inventory carrying cost, shortage cost, and warehousing cost, we develop an analytical model under probabilistic demands, where the retailer can determine the optimal order size and space commitment level jointly. We found the closed-form optimum for a single-period case and the optimal conditions for a two-period case. To evaluate the value of contract flexibility for the two-period case, we compared the total cost under two policies; one with modification, under which the base commitment can be changed at the start of each period and the other without modification. From results of our numerical analysis, we showed that the modification policy is more cost-effective as the variability of demand increases.

Global warming has become one of the most important social responsibilities. After Kyoto protocol for greenhouse gas reduction by climatic change convention came into effect, developed countries are presenting various policies to reduce greenhouse gas that is produced in transport field. One of those policies is modal shift that change from road freight to sea, inland waterway and railway transportation that is eco-friendly. Because increase of road freight brings about road congestion and accident, logistics cost, air pollution and green house gases. Railways are superior to all other modes of transport in mass transportability, high speed, timeliness, safety and environmental-friendliness, but the railway industry has been pushed behind in competition. In developed country's government actively promoted relevant legislation, policies, and countermeasures known as modal shift policies to shift freight transport from road to large volume mode such as railway and ship. In this paper, we discuss the current situation in modal shift, compare it with cases in other countries EU and Japan, identify problems in Korea, and propose the following ways to enhance competitiveness of rail freight.

Distribution Activity for customer is preferred at Physical distribution system in e-commerce, so fast delivery and low distribution cost determine the core competency of enterprise. Because there is no cooperative system between with distribution centers in traditional distribution system, it is difficult to optimize the system. The purpose of this paper is to propose a cost structure model for multi-stage distribution system, which is used for determination of joint lot size and optimal demand and transportation policy. It is expected to contribute to development of algorithm for joint distribution system, which is minimized the transportation cost by the result of this cost structure model.

Though the issue on the integration of maritime transport market in Northeast Asia has a long history, there has never been any notable progress. Especially the lack of country-wise analysis on the barriers of market integration appears as a serious problem for more concrete discussion and the design of the roadmap for market integration. This study analyzes the maritime market of each country in the aspect of infrastructure provision, the development of the industry, change of institutions, and network connectivity and compare the competitiveness of 3 countries in the Northeast maritime market. Furthermore this study analyzes the barriers for market integration on the basis of bilateral relation, i.e. Korea-Japan, Korea-China and Japan-Korea. Based on these analyses, this study finds out the fact that the most serious barrier for market integration among 3 countries is the egocentric policies for the protection of industries in each country rather than any other institutional or physical barriers. In conclusion, this study argues that 3 countries should try to find out a third policy alternative which can make 3 countries enjoy the win-win game, such as route integration among 3 countries and joint venture for the liners operated in the region.

Because smart televisions (TVs) have various and innovative functions that are different from traditional TVs, consumers are front with a complex decision-making problem when they want to buy a best TV among alternatives made by many TV makers. TV manufactures have developed and announced different types of smart TV models and they need a comparative study for evaluating their characteristics. In this paper, we suggest the Analytic Hierarchy Process(AHP) method for deciding the best smart TVs regarding many selection criteria. The method provides a decision support for consumers who like to purchase a smart TV. We describe criteria affecting the smart TV selection through a literature review and suggest a user testing method in order to derive accurate judgments from consumers. Using the Expert Choice software package, we show a an numerical example how the priority of smart TVs are computed.

As open skies polices have permeated all over the world, Korea's basic direction of aviation policy is promoting the benefit of the public and the national carriers' competitive power by establishing open skies agreements between the countries. The open skies' directions should be promoted by considering the relationships of various attributes such as governments, airlines, and passengers. To decide the right directions of open skies, we should investigate the economic effects of open skies policies. This research develops a simulation model to analyze the dynamic characteristics of open skies. By using the developed model, this research analyzes the economic effects of open skies.

The purpose of this study is to analyze traffic volume between the Korean container ports located at the west coast and northern Chinese ports and then the distribution trend of container between Korea and China. The findings of the study are as follows. First, Container traffic between western Korean ports and northern Chinese ports has been increasing due to an increasing trade volume between both countries and geographical accessibility. Second, Seoul and neighboring area tend to use the trade route between the western ports and northern Chinese because of lower logistics costs and time-saved advantage compared to another ports. Third, the growth of the western ports did depend mainly on the northern China oriented growth. Such a fact could leads to the overlapping investment in port development in Korea and another intense competition among national ports to attract cargoes and liners. Therefore, port development policy considering the characteristics and function of national ports have to be established. and also alternatives and strategies for improving the competitive edge of small and medium sized shipping lines against the opening of shipping market have to be worked out.
