This study aims to assess the competitiveness of 30 logistics centers that operate in the hinterland of the North Container Port at Busan New Port. Thirty-two key factors were selected from previous studies to analyze and improve competitiveness and expand business opportunities in the hinterland. Suggestions from logistics experts were also canvassed. These variables were then put through first- and second-factor analysis to verify validity and measure confidence levels; they were later categorized into five factors and 15 sub-factors impacting on competitiveness. The categorized factors were compared using the analytic hierarchy process (AHP) to assess the importance of each factor and sub-factor in the case of logistics centers in the North Container hinterland of Busan New Port. The findings indicate that factors related to the securing of significant amounts of container cargoes were of greater importance. On the other hand, relatively basic factors proved to be less important in improving the competitiveness of the port hinterland.

In this study, the risk factors which derive from the ground condition of typical construction sites are put forward. In order to prioritize the risk elements, the analytical method of AHP was used. The result of using a weighting factor for each risk analysis showed that if the constituency index is less than 0.1, then reliable results and priorities for each of the risk elements can be calculated using the AHP method. From now on, if the range of measured value can be established, the risk or safety value of concrete structures for power lines can be applicable.

As Electronic Commerce(EC) has been emerged and has developed, many researchers have tried to establish EC framework for automated contract and negotiation using agent technologies. Traditional researches, however, often had limitations. They often enforced the user's participations during the automated contract process of agents. They also could only consider a few of the user's requirements for a specific goods and did not have supported the procedures and methodologies for making the best contract. In this paper, we propose business model on EC based on multiagents to overcome the defects of the previous researches. We apply CSP techniques to brokerage process to satisfy various preferential requirements from the user. We also propose efficient negotiation mechanism using negotiation model of game theory. The contract candidates automatically negotiate and mediate in terms of their benefits through the proposed negotiation mechanism. For the optimal brokerage and automated negotiation, the agents process activities for contract on three layers, which are called competition layer, constraint satisfaction layer and negotiation layer in the proposed model. We also design the message driven communication protocol to support the automated contract among the agents. Finally, we have implemented prototype systems applying the proposed model and have shown the various experimental results for efficiency of the proposed model.

This study analyzed factors that should be considered in the process of export diversification strategy formulation and priorities of strategies. We reviewed the extant literature and interviewed six experts. Cross-sectional analysis of a literature review and interview results were used to determine the influencing factors of export. The data for this study were collected from a survey of 68 export experts in Automotive Parts enterprises. Data were analyzed using AHP. As a result of the analysis, the order of importance appeared in the order of internal capacity, correlation buyer effect, entry barriers, technology response, and competition environment. The regions with a high overseas level were product differentiation, centralization, and low cost, whereas those with a low level were in the order of low cost, product differentiation, and concentration. It is meaningful to review the alternatives for adoption of the export diversification strategy and establish a strategy appropriate to the situation. It is necessary to establish a customized strategy considering the characteristics of the global region, and not only internal competence but also mutual relationship with local buyers are important.

Currently, 230 domestic tourist destinations have been designated, established, and operated in accordance with the Tourism Promotion Act. According to the results of preceding research, more than 30% of them have been getting into the stagnation or decline stage. This is becoming a burden to local governments operating and managing tourist destinations, making it necessary to seek resolution measures. Thus, this study determined the activation elements of stagnant/declined tourist destinations regeneration to deal with problems of domestic stagnant or declined tourist destinations and also to regenerate rational and sustainable tourist destinations. This study conducted a survey with experts based on causes for stagnation and decline of domestic tourist destinations suggested by preceding research. Based on the survey results, the activation elements of stagnant/declined tourist destinations regeneration were drawn through the Delphi Technique and Analytic Hierarchy Process. And then the priority and weight of the drawn activation elements of stagnant/declined tourist destinations regeneration were drawn for the sake of reasonable project progress of tour site regeneration. In the results of the analysis, as activation elements of stagnant/declined tourist destinations regeneration, a total of seven upper-attributes, 23 sub-attributes, and 66 detailed-elements were drawn. It would be possible to raise the efficiency of projects and rational decision-making when executing future tourist destinations regeneration projects by using the activation elements drawn. Also, the drawn elements could be applied to the actual tourist destinations regeneration projects as measures for the stagnant/declined domestic tourist destinations' contribution to the vitalization of local economy based on sustainability, prohibition of thoughtless development of domestic tourism projects, and also efficient use of tourism resources.

Land suitability assessments for agricultural crop production determine the suitability of an area in terms of crop yields. We employed the maximum limiting characteristic method (MLCM) and an analytic hierarchy process (AHP) to assess land suitability for Pears (Pyrus) in all Korean provinces (Dos). In general, suitability grades according to the MLCM were much lower than those according to the AHP. The MLCM determined that suitable areas (S1, S2, and S3) exist on 19.55% of the land, whereas 99.08% of the land was classified as suitable by the AHP. Based on information on pear farms in each Korean province in 5 years (1982, 1987, 1992, 1997, 2002, and 2007), the proportion of suitable land area according to the MLCM in each province as compared to all suitable areas was closer to the proportion of areas covered by pear farms in the 5 years in each province and also to the proportion of pear farm areas in 2007 in each province. Based on the assumption that if a province has more suitable areas for pears, more pears will be cultivated in that province, the results of the MLCM can be regarded as more accurate than those of the AHP.

The appropriateness of railway route design is generally evaluated by the future value corresponding to the travel demand or benefit-cost analysis. These methods may have the limitation for the reasons that all the design alternatives cannot be considered, and the differentiation between the alternatives may not be significant because the alternatives are based on the strict basic scheme such as the design criteria. In addition, the cost varies by the design elements. In this study, all the design alternatives are considered with the automatized tool and the design criteria, and evaluated with the multi-criterion decision making method. The weight for each design element with the analytic hierarchical process may be helpful to derive more efficient railway alignment.

There has been a lot of researches on the major motivation of consumer's choice for airlines. Due to the competition in airline industries, most of airlines offer a various level of benefits to customers such as a frequent traveller bonus, a schedule, services in flight including a meal and an entertainment program, a discounted fare and an intangible part of personal service. However, it is very difficult to measure the performance of the customers' benefit and to identify the weight of each factor being considered on the airline choice. In this paper, we focus on the airline choice process for the business travellers. The AHP is applied to evaluate the factors reflecting the business travellers' choice for airlines. This study will be useful to build a marketing plan for the business traveller's market.
