This study figures out the concepts of container transport, logistical cost and the distribution of a company through studying documents, and to suggest logistical cost reduction approach, focused on the efficiency of transport which occupied the considerable portion of the total logistical cost of the company. We analyze and discuss the container loading of multiple items for multiple places of departure and arrival through a case study on S company in South Korea. We suggest a direction to reduce the logistical cost of the companies, analyzing the conditions of multiple items loading, and rule-based systems including an algorithm which determines container-loading for minimum freight expenses. We use data mining and OLAP tools of MS Analysis Services to produce loading rules for multiple items loading and generate OLAP cube and decision trees to validate the rules.

All the major ports around the world as well as those in Korea have been exploring their own strategies to survive rapidly changing marine transport environment worldwide. In particular, Busan New Port under development still fails to meet expected logistical traffic, although it operates 6 berths. That is why it is necessary to point out current challenges in logistical strategy of Busan New Port for fully dealing with logistical traffic. Therefore, this study can propose the following ways to facilitate logistical traffic of Busan New Port. First, it is necessary to apply equal tariff to incentives given to shipping agent under the associations between existing harbors and Busan New Port. Second, it is required to increase governmental subsidy for truck freight transport. Third, it is demanded to seek possible ways to transport export and import freight and thereby create independent logistical traffic. Fourth, it is necessary to contact shipping agents residing in new ports and establish a logistical program for shipping freights via Europe, Middle East and Russia as well as those by way of North America, Japan, Korea and China, ultimately making sustainable marketing strategy to create a series of continuous transshipment freight, not temporary one. Finally, it is advisable to operate networked logistical programs with small- or medium-sized overseas shipping agents in business association with large-scale overseas shipping agents.

This paper investigates changing business transaction under the e-commerce environment and their implications on freight transport industry with some case studies. It shows that an efficient and reliable delivery system is essential for e-commerce as business industries are faced with the stricter and more diversified demands of customer. In addition, many aspects of business practices such as small batch, customized production and just-in-time distribution in the e-commerce environment, in turn, bring about a number of changes in the volume and service patterns of freight transport. E-commerce requires longer transport distances and often higher delivery frequencies. It also entails to a certain extent a modal shift towards truck and air freight transport modes. On the one hand, the logistical requirements of e-commerce goods may stimulate greater complexity in existing supply chain management, causing higher costs. However it is true that the increased visibility of goods through more efficient information flow allows more efficient and effective transport management in the logistics system.

In order to reduce packaging and logistics costs for any business, it is important to identify opportunities for improvement throughout an entire logistics system including measurement of the performance and cost of packaging. Although the importance of packaging in a supply chain has been recognized by many scholars and experts, the total cost and value of packaging have not been successfully estimated. This paper reviews the recent researches and articles that tried to quantify the value of packaging focusing on the business decision between reusable and expendable shipping container systems. Three key factors such as cost, ownership, and standardization are identified and discussed in terms of impact on supply chain costs and performances. It is important to understand that the decision of a package system can change a logistics activities and even entire logistical system. Hence, the total cost and value of transport packaging should be calculated with understanding of interactions with logistical activities throughout supply chain. Identifying the opportunities and constraints of packaging changes on total logistics cost and activities must be carefully examined before implementation of a packaging system.

For the connection of trans-continental railway network, it is critical to conquer the break-of-gauge problem at the borders in different countries. Up to now, the best solution seems to be the employ of the auto-changable gauge equipment. Countries, such as Russia, Japan are developing and commercializing auto-changable gauge equipment to maximize transport efficiency for the trans-continental network. The efforts to search a suitable logistical service are also underway. In this paper, technology and development trend of this equipment in several countries is indicated through inspecting and analyzing the historical and current situation of development, operating mechanism and technical problems. As the basic technology of auto-changeable gauge is not well developed in our country, the purpose of this study is to search an approach to fix the research direction, and find practical ways to international cooperation.

In many distribution systems important cost reductions and/or service improvements may be achieved by adopting an efficient inventory policy and proper selection of facilities. These efficiency improvements and service enhancements clearly require an integrated approach towards various logistical planning functions. The areas of inventory control and transportation planning need to be closely coordinated. The purpose of this paper is to construct an integrated model that can minimize the total cost of the transportation and inventory systems between multiple origin and destination points, where in origin point i has the supply of commodities and in destination point j requires the commodities. In this case, demands of the destination points are assumed random variables which have a known probability distribution. Using the lot-size reorder-point policy and the safety stock level that minimize total cost we find optimal distribution centers which transport the commodities to the destination points and suggest an optimal inventory policy to the selected distribution center. We also show if a demand greater than one unit will occur at a particular time, we describe the approximate optional replenishment policy from computational results of this lot-size reorder-point policy. This model is formulated as a 0-1 nonlinear integer programming problem. To solve the problem, this paper proposes heuristic computational procedures and a computer program with UNIX C language. In the usefulness review, we show the meaning and validity of the proposed model and exhibit the results of a comparison between our approach and the traditional approach, respectively.

Purpose - In the year of 2015 and 2016, one of the items that got attention in CES was a drone. It has been 100 years since a drone emerged, but most were used for military purposes. As its use became diverse as of 2010, it got attention of the general public. In Korea, it was in 2011 that a drone was known to the public through an aerial video shooting for television program. This study tried to come up with suggestions by comparing domestic with overseas cases, and tried to consider the related technologies and systems with applying the role of drones in logistics service. Research design, data, and methodology - The overseas cases were regarded as drone's logistical purpose. The Prime Air service by US Amazon is still not commercialized and under pre-testing due to Federal Aviation Regulations, although it started in 2013. In Germany, DHL succeeded in delivering service testing which is called Parcelcopter, but it is not commercialized yet. Other than these, there are more attempts to prepare logistics service in China with Taobao, in France with Geopost's test, and in Africa. In Korea, CJ Korea Express tested delivery with a self-developed drone Results - In order to study for utilizing drones for logistics as the prerequisites, some overseas and domestic cases, which are currently considered, were reviewed. Also, the technologies and institutional requirements to commercialize drones for logistical purpose were reviewed. The reasons for using drones in logistics is to ensure the price competitiveness by reducing cost. The empirical test also will be needed because drone pilot areas are designated by ministry of land, infrastructure and transport. Conclusions - In order to utilize drones in logistics and foster the industry, this study would like to suggest the followings. First of all, size of drones for logistics needs to be fixed and their operating system should be standardized. Centralized investment resources are needed through standardization to ensure the market occupancy. Secondly, it is necessary to get the converged businesses that do research, develop and commercialize drones with the investment of private sector. Example can be found in Korea aerospace Industries. We can respond to the rapid growth of the market with intensive investing by integrating the private sector investment. Thirdly, institutional arrangements are needed to be established quickly. In the case of high-technologies like drones, institutional support often does not follow the rapid development of the technology. The problems can be found in securing drones-only airspace, creating drone-specialized pilot's license, matters related to remote controller and complementary regulations for drones in Aviation Act. If these regulations are not prepared or complemented at the right timing, technologies cannot be commercialized even though the development is completed. Fourthly, there is a need to secure the transparency regarding possible privacy and personal information protection problem while operating drones. Finally, in order to foster this new industry, government should focus on supporting R&D more in the long term than short term outcomes.
