The university library is supposed to build its collection in an organized and controlled manner to achieve its one goals for information services, and the book selection is an essential element of librarianship to support the university process of research and education effectively. This study focuses on the faculty influence on the book selection process of the university library. the researcher concludes that too much hegemony in the hands of professors is not appropriate and at least part of it should be handed over to librarians.

Recently increasing amount of efforts has been devoted to the improvement of logistics in the marine products industry. Yet, few studios have been conducted on the development of site selection models of marine products centers. This paper Proposes a systematic assessment model for the decision making, which is composed of a set of evaluation criteria and an appropriate evaluation method. In choosing criteria we consider completeness and comprehensiveness to reach a right solution. For more flexibility of the model in the future, this study proposes two sets of criteria according to the size of planned centers. The Analytic Hierarchy Process (AHP) is adopted in this study, since the criteria incorporate both subjective factors and objective factors and the AHP is known effective in the situation. This study then illustrates the model application with plausible alternatives. Finally, a dependency problem in the decision criteria is discussed and the Analytic Network Process (ANP) is recommended, in the context, as e solution method.

The improper use of input and output factors in DEA has a critical and negative impact on the efficiency measurement and the discernment of decision making units(DMUs) : hence the proper selection Process of the factors should precede the actual applications of DEA. In this paper, we propose a new approach to selecting proper factors based on Tofallis' partial efficiency evaluation method(1996). With the approach, the factors aye clustered by measuring their respective partial efficiencies and analyzing the rank correlations of them. The method and procedure we propose in this paper are then applied to measure the efficiencies of the public libraries in Seoul District area, and the results show that the proposed approach can provide meaningful information to improve discernment of the DMUs while using less number of input factors (and less information). The proposed method can be effectively used in the situation where the number of the DMUs to be considered is relatively small compared to the number of available input and output factors, which usually lessens the power to identify the inefficient units in DEA.

생활 수준의 향상으로 환경의 질에 대한 주민들의 관심이 높아짐에 따라 쓰레기 매립지와 같은 환경 혐오시설의 부지 선정 문제가 사회 문제로 대두되고 있다. 따라서 본 연구에서는 다량의 환경학적 정보를 저장, 관리, 분석, 표시할 수 있는 GSIS와 의사 결정 과정에서 사용될 수 있는 AHP를 이용하여 쓰레기 매립지를 평가하는 방법을 연구하고자 한다. AHP는 관계 집단들의 의견을 적절히 반영시킬 수 있는 유연성을 가지고 있기 때문에 GSIS와 연관시켜 사용하면 환경 혐오시설의 부지 선정 문제에 매우 유용하리라 생각된다.

This paper aims to construct an effective decision making model on selection of product design in product development using fuzzy AHP technique. It is expected that this paper contributes to enhancement of company's market competitiveness by shortening the lead time to develop a new product and minimize initial investment. The proposed model using fuzzy AHP enables quick decision making by integrating and analyzing all customer requirements related to a product. In addition, it can deal with vagueness and uncertainty of decision making process using fuzzy set theory. Decision making processes for evaluating the best selection of product design are also constructed to describe the exact concept of development. A tennis racket is shown as an example. The proposed model is expected to be applied in various fields of managerial decision making processes as well as of product development process.

Case-based Reasoning (CBR) is widely used in business and industry prediction. It is suitable to solve complex and unstructured business problems. Recently, the prediction accuracy of CBR has been enhanced by not only various machine learning algorithms such as genetic algorithms, relative weighting of Artificial Neural Network (ANN) input variable but also data mining technique such as feature selection, feature weighting, feature transformation, and instance selection As a result, CBR is even more widely used today in business area. In this study, we investigated the usefulness of the CBR method in forecasting success in implementing ERP systems. We used a CBR method based on the feature weighting technique to compare the performance of three different models : MDA (Multiple Discriminant Analysis), GECBR (GEneral CBR), FWCBR (CBR with Feature Weighting supported by Analytic Hierarchy Process). The study suggests that the FWCBR approach is a promising method for forecasting of successful ERP implementation in Small and Medium sized Enterprises.

Data mining is the process of finding and analyzing data from a big database and summarizing it into useful information for a decision-making. A variety of data mining techniques have been being used for wide range of industries. One application of those is especially so for gathering meaningful information from process data in manufacturing factories for quality improvement. The purpose of this paper is to provide a methodology to improve manufacturing quality of fuel tanks which are auto-parts. The methodology is to analyse influential attributes and establish a model for optimal manufacturing condition of fuel tanks to improve the quality using decision tree, association rule, and feature selection.

According to growing interest in environmental quality with improvements of a standard of living site selection problems such as waste landfill sites, caused regional conflicts. This study investigates a waste landfill estimation method that was used to for storage, management, analysis and display of environmental information provided by geo-spatial information system(GIS) and analytic hierarchy process(AHP) as a decision-making method. If GIS is integrated with AHP, site selection problems of environmental hatred facilities shall be able to be very useful, because of AHP with flexibility which appropriately reflects opinions of the related group.

Recently, due to the primary emphasis of environmental problem, the proper selection of the prevention technology systems necessary for Dioxin treatment has been one of the critical issues in the industrial sector. This paper shows how an Analytic Hierarchy Process(AHP) model can be used for assessing the performance of selected prevention technology systems: SDA/BF-SCR, SNCR-SDA/BF, SDA/BF, EP-WS-SCR, ED-WS, and EP-SCR-WS essential for Dioxin treatments. The final results show that SNCR-SDA/BF is the most attractive prevention technology system to use in an incinerator system, followed by SDA/BF-SCR, SDA/BF and EP-WS-SCR. This is consistent with the information that we found with respect to the elements that were taken into consideration. Sensitivity analysis is also provided here.
