This paper aims to provide strategies to attract container cargoes for the Incheon port by analysing O/D of the container cargoes with the year-2004 export and import data from. The Korean customs service. O/D analysis was carried out with establishing optimal zones, which are defined as City, Gun, Gu(Korean administrative districts) to which the export-import service can be provided from a certain port with minimized freight(or transport) cost and stevedoring fee. For the Incheon port, 35 administrative districts including Seoul and Incheon in Kyunggi-Do and Kangwon-Do are recognized as the optimal zones, and approximately 25.50% of around 2.02-million-TEU per year of the cargoes from the woes are exported and imported through the pan. The strategies to attract container cargoes was suggested by comparing the Incheon port to supposed-competitive pons. The Busan portn(64.89%), Guangyang port(4.46%) and Pyeongtaeck port(3.35%) are supposed as the competitive pons which have a large proportion of handling the cargoes from the optimal zones. When comparing the Incheon port to these ports, The Incheon pan requires a distinctive cost strategy, providing incentives to attract shipping companies and cargoes, improving efficiency related to loading-unloading at the port, and reinforcing Feeder-Network and advertisements about cost-saving to the shippers(the owners of goods) in the national capital region. Consequently, the mentioned requirements are suggested as the strategies to attract cargoes for the Incheon port.

Customer profitability recognition is easier with CRM enabling technologies and the strategy of firing unprofitable customers prevails in the market. However, in the digital and Internet age, network externality is becoming more important. Therefore, the concern over firing unprofitable customers has increased. Our research is intended to develop strategic guidance for customer selection when firms implement CRM in the market with network externality.

Feedback strategies of a qualitative competitive game between two players can be designed such as to influence parameters of a mechanical system to induce chaotic behavior. The purpose is to reduce the options and effects of the opponent's strategy. We show it on a case with dynamics specified by a nonautonomous Duffing equation with the players represented by damping and external forcing, respectively. It seems however that the conclusions can be made valid generally.

This paper presents a schematic process based on the method of eliminating dominated strategies to obtain the optimal bidding strategy Pursuing the Nash equilibrium Point. The Proposed approach is demonstrated for a bidding game in a generation competitive market with 2-dimensional bidding strategy vectors constituting a price-quantity strategy curve.

The borderless global economy has accentuated the importance of knowledge as the most critical source of competitive advantage. Thus, knowledge management has become a strategic mandate for most world-class organizations. A key enabler for implementing an effective knowledge management system is advanced information technology. Strategies for developing an enterprise-wide knowledge management system Infrastructure with embedded information technology are discussed. In particular, this paper discusses the concept of a knowledge management life cycle- -knowledge capture, knowledge development, knowledge sharing, and knowledge utilization, and how applications of new information technology support each step of the knowledge management practices within and between organizations is suggested.

Building the competitive advantage of Korean multi level marketing(MLM) companies is an important task when American multi-level marketing companies has successfully made inroads into Korean market. In this study, we search for the efficient marketing strategies for the MLM companies through a survey of distributors and consumers. The results indicate that the MLM companies must first deal with their image problem and improve their product quality and physical distribution system.

Power transactions are considered as noncooperative game in that participants compete each other to win the bidding game, and as cooperative game in that they have to cooperate to apply the result of bidding game to the physically interconnected power system. This paper applies both noncooperative and cooperative game theories in analyzing the entire process of power transaction.

The congestion management is a key task for enhancing the effectiveness of transmission pricing mechanism in a competitive electricity market. In this paper, the zonal method of congestion management is analyzed quantitatively using equilibrium concept, and compared with the nodal pricing method. It is shown that the generation firm uses different strategies in the two methods, and the overall performance of zonal congestion management depends on the determination of zones.

In Manufacturing using time-based strategies, as a competitive advantage, time is the equivalent of productivity, quality, innovation. In addition, time-based sourcing's impact on competiveness is not limited to cost control but also influences the performance of its adoption. This paper is to examine the relation between the level of time-recognition and supporting and performance of time-based sourcing by the empirical study.
