A New Ship Scheduling Set Packing Model Considering Limited Risk
Kim, Si-Hwa ; Hwang, Hee-Su ;
Journal of Navigation and Port Research, volume 30, issue 7, 2006, Pages 561~566
DOI : 10.5394/KINPR.2006.30.7.561
In this paper, we propose a new ship scheduling set packing model considering limited risk or variance. The set packing model is used in many applications, such as vehicle routing, crew scheduling, ship scheduling, cutting stock and so on. As long as the ship scheduling is concerned, there exits many unknown external factors such as machine breakdown, climate change and transportation cost fluctuation. However, existing ship scheduling models have not considered those factors apparently. We use a quadratic set packing model to limit the variance of expected cost of ship scheduling problems under stochastic spot rates. Set problems are NP-complete, and additional quadratic constraint makes the problems much harder. We implement Kelley's cutting plane method to replace the hard quadratic constraint by many linear constrains and use branch-and-bound algorithm to get the optimal integral solution. Some meaningful computational results and comments are provided.
A study on the Relationship of Hub Ports' Transshipment and the Trade in East Asia: Focusing on Korean Ports

This paper is a study of the relationships between trade and transshipment in Korea. Through the analysis of the data collected, a comprehensive model has been developed to analyze and predict relationships between trade and transshipment. By using analyses of port and trade evolution in Asia, the model identifies some important results. An application of the model to forecast developments in selected regions in China is also included in this paper. The paper provides a basis for shipping companies to decide on appropriate transshipment port strategies, and provides important theoretical references for Korean ports' development Supported by Shanghai leading Academic Discipline Project, project Number: T0602.
A Study on the Performances of Strategic Alliance in Liner Shipping

The purpose of this paper is to study a relationship between alliance success factors and performances of strategic alliance. In order to achieve the purpose of this research, factor analysis, reliability and validity and regression method are used. In conclusion, alliance success factors can be divided as mutual complementarity and information sharing factor, sharing and mutual agreement of vision and goal factor, performance management factor and culture and organization factor. According to regression results, all of four factors affects significantly dependent variables. Among them, mutual complementarity and information sharing mostly affects each dependent variable.
A Study on the Prospect of the Maritime Transport Market Integration in the Northeast Asia
Kim, Tae-Seung ;
Journal of Navigation and Port Research, volume 30, issue 7, 2006, Pages 585~590

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.

Port development has been remarkably increasing due to the progress of industrialization in ASEAN area. Especially, Vietnam has increased the international physical distribution in this area rapidly. The main issues facing decision makers at container terminals in Vietnam are how to expand the existing container terminals and construct new container terminals. In this paper, we performed the basic design based on simulation analysis in order to support the expansion of Quy Nhon port in Vietnam as a case study. The preliminary capacity analysis was conducted on the one berth at the port to analyze the scale of C/C(Container Crane)and yard area. Alternative scenarios were created based on the preliminary capacity analysis and the detailed simulation analysis was conducted for supporting the scenarios.
Risk Priority and Allocation of Private Investment in Port Development
Seong, Yu-Chang ; Youn, Myung-Ou ; Keum, Jong-Soo ; Kinzo, Inoue ;

The Port Development has been achieved by the Government because it needs large scale of funds. However, since 1994, the Govenment has been implemeting private investments for constructing and operating the ports and so on. Although the Government had high expectation that it could expedite the expansion of the port facilities, there were many problems in view of construction, management, financial and social environment. This study figure out that most of the important reasons are the uncertainty of risk allocation between private investors and the Government, using with Analytic Hierarchy Process. It is expected that the results of this study will encourage more private investors to participate in port private investments in the future.
Compact Low-Pass Filter with Sharp Skirt Characteristics and Broad Stopband

DOI : 10.5394/KINPR.2006.30.7.607
A new compact microstrip low-pass filter and its equivalent-circuit model are developed. The philosophy of the structure behind this novel microstrip low-pass filter is simple as it is composed of a pair of symmetrical parallel coupled-line and an open-stub. With this configuration, a finite attenuation pole near the stopband cutoff frequency is available and adjustable by simply tuning the circuit parameters. Furthermore, the rejection bandwidth of this type of low-pass filter can be extended. In order to validate the feasibility of the proposed design method, a low-pass filter based on a microstrip structure is designed, fabricated, and measured. Experimental results agree very well with the simulation and analytical results.
A Study on the Radar Image Generation Method for Ship Handling Simulator

This paper proposes a method for generating radar images used in a ship handling simulator, which includes mathematical logics based on radar equations and information from Openflight format files. In order to make radar image much similar to that of real radar in PPI type, the proposed mathematical logic derives radar video signals under the consideration of not only the data form flight format file of simulation scenes, but also geographical radar's position. The proposed method is considered useful to make radar images in ship handling simulator with accuracy and reality.
