Existing railway bridges have been going through various improvements since the past, with new improvement plans being formed based on social and technological demands. However, there is the need, above all, for an efficient execution plan due to the great number of sites and excessive amount of required expenses contrary to limited assets. The system itself must be held in question in order to systemize various improvement plans, to define and describe factors while utilizing evaluation methods for significance and correlation to achieve generalization. This paper is focused on determining the priority of various improvement plans through the optimization selection process of mutually evaluating alternative plans under various evaluation standards, thus corresponding to the decision-making purpose. The AHP analysis technique was applied for systemization setting and preference evaluation, while the HPT procedure was applied to develop and select appropriate improvement plan factors.

이 논문은 Minnesota대학 Paul Campus 도서관 부관장인 존슨(P. Johnson)이 Journal of Academic Libraianship, Vol. 16, No. 4(Sept, 1990), pp.222-229에 게재한 "Matrix Management: An Organizational Alternative for Libraries"을 완역한 것으로, 도서관의 전통적인 조직구조에 대한 대안을 모색하는데 참고할 수 있는 이론적 논문으로 사료됨. 도서관조직구조가 점점 복잡해 짐에 따라 다양한 방안들을 모색하여 왔다. 이 논문은 전통적 계층구조에 대한 대안으로서의 매트릭스구조의 효용에 관하여 논의 한 것이다. 매트릭스관리가 매우 성공적으로 이루어질 경우에는 사서들에게 유연성을 증대시키기 위한 신전략과 고도의 전문적 독립성, 그리고 보다 균형된 의사결정과정을 제공해 준다. 제2차 세계대전까지만 해도 도서관을 포함한 대다수 기관의 조직구조는 몇 가지로 나눌 수 있었다. 비록 이들 조직구조가 바뀌게 되었다 하더라도 그것은 의도적인 계획하에서 진전된 것이 아니라 안정적이고 예측가능한 환경에 매우 적합하도록 자연스럽게 이루어진 것이다. 다만 최근 여러 해 동안 급격한 환경변화로 인하여 보다 새로운 조직구조가 발전하게 되었는데, 이는 자연진화적인 조직변화라기 보다는 오히려 특정적 요구를 충족시키기 위한 자의적인 계획의 결과라고 하겠다. 이와 같은 급격한 변화에 대처하도록 특별히 계획된 매우 혁신적인 조직구조중의 하나가 조직매트릭스이다. 이 논문은 대학도서관에 있어서 조직구조, 조직대안으로서의 매트릭스구조, 매트릭스경영관리의 효용 등 세 가지의 문제에 대하여 고찰하고자 한다.<역자주>

Korea's agricultural reservoir is one of the country's major infrastructures and plays an important role in people's lives. However, aging reservoirs are a risk for life and property. Currently, large and small dams and reservoirs have been constructed nationwide for more than 40 years of aging. Dams and reservoirs built nationwide are managed by various institutions. Therefore, it is difficult to manage all dams and reservoirs due to cost and time. Managers in the field with less management personnel and lack of expertise should be able to quickly identify risk factors for multiple reservoirs. In this study, risk factors such as seepage, leakage, settlement slide, crack and erosion were selected. To assess the risk of the items, we used the analytical hierarchical process (AHP), one of the Multi-Criteria Decision Making (MCDM) methods. The analysis showed that seepage has the greatest impact on reservoir collapse. It is judged that the priority of detailed diagnosis can be determined by evaluating the risk of dam reservoir collapse in a convenient way in advance using the calculated weight.

It would cause a serious problem in the panel data when panel attrition is concentrated on certain socioeconomic groups. Using the GOMS, this study investigates whether there exists non-random attrition bias in the data and seeks for feasible solutions to minimize the bias. The results of logit analyses show that panel attrition in the GOMS results mainly from surveying system but not from the surveyed. Therefore, the result suggests to develop well-organized management skill and systems as well as to construct weighting methods.

The International Civil Aviation Organization(ICAO) recently established the Global Aviation Safety Plan(GASP) for national aviation safety management, along with the enactment of Annex 19, Safety Management System(SMS). ICAO require the establishment of the 'States Safety Programs(SSP)' for countries with excellent safety evaluation, including Korea, and the establishment of aviation safety supervision systems for all Contracting States by 2017 under the enactment of ICAO Annex 19. Required. The Ministry of Land, Infrastructure, and Transport has continuously invested in R&D to secure such aviation safety systematically, and is making efforts to develop and disseminate related technologies by establishing long-term R&D roadmaps. A study on aviation safety supervision among the system-based aviation safety supervision support technology development R&D project, which is underway as part of the aviation safety technology development project of the Ministry of Land, Infrastructure and Transport. We conducted a study to see if this methodology logically guarantees reasonableness.

The purpose of this study is to analyze the factors of the main selection criteria of the contract form used to conclude the sales contracts of used ships and to assist parties in selecting the most suitable contract form for trading situations. The methods of the study are based on identifying the factors from the questionnaires using analytic hierarchy process analysis, following the selection of typical details through interviews with the S&P Broker Group and finding the solutions that match each detail. The analysis shows that ship traders prefer the Norwegian Sales Form (NSF) to NIPPONSALE for various reasons. Considering the sellers' situations, NFS is the more reasonable option for major countries, except Japan. NIPPONSALE is relatively more focused on the advantages of the buyer's conditions, including for Japan. It is important to select the appropriate clauses from these types of contract, according to the trading conditions, including the main and additional terms, in order to create a mutual agreement between the shipper and the consignee that leads to more cooperation and balances the purposes of both parties in adjusting the time for securing and disposing of the vessels.

This study examines problems with using the conventional analytic hierarchy process (AHP) method and proposes a method of weight adjustment as a modification of AHP. AHP is a method for transforming complex decision problems into a hierarchal structure, which is composed of elements in the upper and lower levels and then using pairwise comparisons to evaluate these elements and subsequently to obtain their relative weights. The elements' relative importance is reliable if the elements in the lower hierarchical levels (sub factors) that comprise each element in the upper hierarchical level (primary factor) are equal in number. In other words, if the number of sub factors is different for each primary factor, a serious error is expected as a result. Therefore, this study proposes a modification of AHP that can avoid such an error when AHP is used. Specifically, an error that arises from different number of sub factors (matrix size) can be overcome by making the number of sub factors identical for each primary factor. The resulting model has been validated through the applications in different AHP hierarchical structures.

의사결정지원시스템으로서의 DW는 기업정보시스템에서 두뇌역할을 담당하는 만큼 전략적 중요도에 있어서 매우 중요한 역할을 차지하고 있다. 이러한 추세와 더불어 많은 기업들이 DW구축에 엄청난 예산을 투입하여 시스템을 구축하지만 프로젝트의 실패 역시 흔하게 찾아 볼 수 있는 사실이다. 이러한 실패의 주요인은 기술적인 문제에서 발생하기 보다는 낮은 시스템 활용도와 명확하지 않은 분석요구사항에서 주요원인을 찾아 볼 수 있는데 이는 구축단계에서 이용자와 이해관계자들이 DW의 시스템적 목적을 제대로 이해하지 못하여 사용자 관점의 요구사항을 제대로 제시하지 못하고 이에 따라 시스템의 활용도 역시 낮아지는 데에서 본질적인 원인을 찾을 수 있다. 본 논문에서는 시스템의 사용자가 요구사항을 적극적으로 제시하고 시스템에 끊임없는 관심을 같도록 유도하여 이용자의 요구사항을 충족시킨 수 있는 정확한 주제분야와 분석관점을 발굴함과 통시에 시스템의 활용도를 높이기 위한 방안으로 정형화되고 주기적인 분석정보를 제시하기 위하여 정적 Reporting을 위한 Web Reporting Tool과 함께 시스템의 이용자와 주기적으로 Communication을 유지하여 시스템에 지속적으로 관심을 갖도록 하기 위한 상호 Communication기능을 통한 문제의 해결방안을 제시하고자 한다.

This study analyzed and compared the importance and priority of location decision factors in Foreign Direct Investment Firms managing the manufacturing business in the nation's southeastern economic zone, and in expert group by using AHP analytical technique based on examining the location theory and the prior research of real estate for industry. Also, it analyzed difference in importance and priority for location factors by corporate scale, by business category, and by location type targeting only foreign direct investment firms, and offered references necessary for location decision-making. In addition, to elicit useful information for policy related to location decision factors for foreign direct investment firms, the implications were elicited by analyzing the results recognized between foreign direct investment firms and expert group on information elements regarding investment satisfaction, business bottlenecks, and location decision process. The considerable gap was indicated in importance and priority of location decision factors considered between the nation's foreign direct investment firms and real-estate expert group for industry. As a result of analyzing by reflecting the corporate characteristic variable in location assessment model unlike before, the importance of the competitive advantage factor and the business strategic factor was indicated to be very high.
