Although Busan Port is a world-class transshipment port, it is geographically divided and, despite the continuous increase in transshipment volume, ITT port integrated operation is not being performed, reducing port operation efficiency. In addition, the operation raises the problem of inefficiency in social and economic aspects, along with an increase in the volume of transshipment transport and the resulting increase in transshipment transport costs. This paper deals with the necessity of forming an integrated operation organization to carry out the ITT joint dispatch in the process of improving the ITT efficiency in Busan Port, and the organization structure centering on the transport companies and freight owners performing the Busan Port ITT. We intend to make a proposal for the establishment of an integrated operation organization in the form of a consortium and support plans. In addition, through analysis of implications, the role of the ITT stakeholders in Busan Port and related organizations will be addressed.

The future warfare is known as an effective centric paralysis warfare where military high technologies such as pinpoint strikes are applied. In this future warfare, for supporting military operation leadership and power of concentration in the combat, a new concept of logistic support is required and the focused logistic is proposed as an alternative. To implement this focused logistic, asset visibility should be assumed for every combat units in real time. However, current logistic information systems provide only limited information. In this study, a prototype information system for class 2 and 4 supplies is proposed for overcome limitations of current information system. The developed prototype zooms in on combat units providing business process integrations and logistic function synchronization. Also, asset visibility, the essential element of focused logistics, is presented and utilized to show the speedy and effective logistic support.

If the development of Integrated Logistics Support (ILS) for maintenance of the end step is conducted systematically and efficiently, the weapon system lifecycle can be postponed and the availability can be improved. DEFense CONdition (DEFCON) is maintained as perfect. Nevertheless, like its importance, the guide for maintaining the depot performance is applied differently for each weapon system. The errors that can result cause additional cost, etc. ILS development at depot level maintenance is different from full scale development. Therefore, this study distinguishes the management and deployment section for the development concept. An additional way to perform an efficient development of depot maintenance element when determining the depot maintenance period were presented. This study examined how the Reliability, Availability, Maintainability (RAM), Logistics Support Analysis (LSA), and ILS 11 elements intersect at the depot maintenance sources. An analytical study of concrete adoptable plans was performed. The systematic adoption of a development procedure can make it possible to calculate the adoptable development cost. In addition, it can be helpful for improving the quality level and practical use of work products.

The Korean navy has been using the ICS(Integrated Communication System) to transfer a command, control and information on the naval ship. The major equipment for the ICS has been imported from abroad, so that there were some problems such as lack of logistics support, leaking military secrets. This paper describes considerations for the development and the key technology of the domestic ICS which is developed to solve the problems mentioned above and to integrate various future communication elements on the naval ship.

Purpose: Marine transportation companies must improve service quality to secure competitive advantage and continuous relationships with customers. This study explores the value and necessity of service quality in the industry by empirically identifying the factor that would have the largest effect on the improvement of service quality, also examining whether such improvement may actually influence continuous relationships. Research design, data and methodology: Based on an online survey with those in the Korean marine transportation industry, this study conducted statistical analyses using structural equation modeling. Based on relevant previous studies, the current study constructed a total of 55 survey questions. Finally, 281 questionnaires were collected, but 68 were excluded owing to invalid responses. Results: Information service attribute had the largest effect on service quality, whereas communication did not demonstrate a significant influence. In addition, distribution and information services exerted a positive effect on service satisfaction through service quality, and finally influenced relationship continuity. Conclusions: The results shows that marine logistics service quality strategies which were centered on time or local factors, should be considered in terms of the development of innovative services. In particular the improvement of information service systems and strategies in changed business environment.

For forecasting air cargo demand from Incheon National Airport to all of airports in the United States (US), this study employed the Seasonal Autoregressive Integrated Moving Average (SARIMA) method and the time-series data collected from the first quarter of 2003 to the second quarter of 2016. By comparing the SARIMA method against the ARIMA method, it was found that the SARIMA method performs well, relatively with time series data highlighting seasonal periodic characteristics. While existing previous research was generally focused on the air passenger and the air cargo as a whole rather than specific air routes, this study emphasized on a specific air cargo demand to the US route. The meaningful findings would support the future research.

This thesis examines the problems faced in the electronic trade platform for which improvements are necessary, and suggests various ways of overcoming those problems. Practical implications regarding the advancement of Korea's u-TradeHub system are as follows. First, from the technical and legal aspects, to make up for a lack of support systems for spread of users, it is required to promote customized advertising strategies through Ministry of Knowledge Economy and establish a global certification system. Second, document standardization and digitalization should be achieved in advance to make the documents distributed through the e-Trade platform in a seamless manner. Furthermore, an ongoing global network development project should be promoted through the e-Trade platform to achieve standardization. Third, from the operational aspect, it is important to maintain an integrated and systematic relationship with related organizations. Because vertical integration among logistics service providers and GSCM are enabled through the e-Trade platform, it is necessary to standardize global network-based linkage and operating systems.

This paper proposes an effective method on the DFILS(Design for Integrated Logistics Support) in ammunition development applying QFD(Quality Function Deployment) method. The goal of this research is to define the Design for ILS approach at the start of the ammunition development and to yield a set of reusable requirements. Based on 000mm High-Explosive(Warship ammunition) development work, a QFD software tool, CUPID, was used to analyze and define the field force's requirements. Additionally, a set of reusable requirements are identified and defined for use during the Design for ILS development phase in the next-generation ammunition development process. These set of requirements that consider both the priority and importance of the VOC(Voice of Customer) will contribute to the early phase of the ammunition development to implement the Design for ILS specialty engineering effort.

Hierarchical forecasting strategy does not always outperform direct forecasting strategy. The performance generally depends on demand features. This research guides the use of the alternative forecasting strategies according to demand features. This paper developed and evaluated various classification models such as logistic regression (LR), artificial neural networks (ANN), decision trees (DT), boosted trees (BT), and random forests (RF) for predicting the relative performance of the alternative forecasting strategies for the South Korean navy's spare parts demand which has non-normal characteristics. ANN minimized classification errors and inventory costs, whereas LR minimized the Brier scores and the sum of forecasting errors.
