Recently a multi-attribute structure analysis method is one of the evident areas of important points in the decision support system analysis. This research developed an internet/intranet-based solution builder for a three-step decision support system using fuzzy-AHP in the view of 1) brainstorming far the idea generation, 2) fuzzy-AHP (fuzzy analytic hierarchy process) as a multi-attribute structured analysis method and 3) aggregation logic model to integrate the results of individual analysis. We applied this decision support system to the make-or-buy decision problem for school foodservice system considering the multi-attributes in the decision making. A computer program is developed and demonstrated it internet/intranet-based decision problem. It was known that this solution builder provides decision makers a good tool for mate-of-buy group decision making.

본 연구에서는 매수인이 부동산을 검색할 때, 매수인의 다양한 성향을 고려할 수 있는 새로운 검색 시스템을 제안한다. 이를 위해 부동산 가격에 영향을 미치는 요인들을 분석한 뒤, 지역요인 및 개별요인으로 분류하였다. 다요소 의사결정(Multi-attribute Decision Making) 알고리즘을 통해 매수인이 입력한 검색조건을 분석하여 가중치를 부여하고, 부동산 후보지간 엔트로피 척도를 통해 최적의 부동산 후보지를 도출하도록 설계하였다. 본 검색 시스템의 효용성을 평가하기 위해 부산지역의 실제 부동산 정보를 이용하여 실험을 진행하였다. 실험결과, 본 다속성 통합 검색 시스템은 매수 아파트 검색 시 지역분석과 개별분석을 용이하게 해 주었다. 또한 한번 검색으로 여러 지역의 부동산 후보들을 비교분석함으로써 매수인의 탐색비용을 절감시킬 수 있었다.

Measurement of attributes is often highly subjective and imprecise, yet most MADM methods lack provisions for handling imprecise data. Frequently, decision makers must establish a ranking within a finite set of alternatives with respect to multiple attributes which have varying degrees of importance. The problem is more complex if the evaluations of alternatives according to each attribute are not expressed in precise numbers, but rather in fuzzy numbers. Analysis must allow for lack of precision and partial truth. The advantages of a fuzzy approach for MADM are that a decision maker can obtain efficient solutions all at once without trial and error, and that this approach provides better support for judging the interactive improvement of solutions in comparison with o decision making method. The algorithm used in this study is based on the concepts of vague set theory. Linguistic variables and vague values are used to facilitate a decision maker's subjective assessment about attribute weightings and the appropriateness of alternative versus selection attributes in order to obtain final scores which are called vague appropriateness indices. A numerical example is presented to show the practical applicability of this approach.

Interval-valued neutrosophic hesitant fuzzy set (IVNHFS) is an extension of neutrosophic set (NS) and hesitant fuzzy set (HFS), each element of which has truth membership hesitant function, indeterminacy membership hesitant function and falsity membership hesitant function and the values of these functions lie in several possible closed intervals in the real unit interval [0,1]. In contrast with NS and HFS, IVNHFS can be more flexibly used to deal with uncertain, incomplete, indeterminate, inconsistent and hesitant information. In this study, I propose the novel correlation coefficient of IVNHFSs and my paper discusses its properties. Then, based on the novel correlation coefficient, I develop an approach to deal with multi-attribute decision-making problems within the framework of IVNHFS. In the end, a practical example is used to show that the approach is reasonable and effective in dealing with decision-making problems.

Recently a new multi-attribute analysis method is one of the evident areas of important points in the decision support system analysis. The area of decision support system may be broken into three primary area: idea generation, multi-attribute structured analysis method, and the integration of the results of analysis. This research developed an internet/intranet-based solution builder for a three-step decision support system in the view of 1) brainstorming for the idea generation, 2) analytic hierarchy process as a multi-attribute structured analysis method and 3) aggregating logic model to integrate the results of individual analysis. A computer program is developed and demonstrated in internet/intranet-based decision problem. This solution builder provides decision makers a good tool for remote group decision making.

Monitoring is the most important part of the construction and operation of the embankment dams. Applied instruments in these dams should be determined based on dam requirements and specifications. Instruments selection considered as one of the most important steps of monitoring plan. Competent instruments selection for dams is very important, as inappropriate selection causes irreparable loss in critical condition. Lack of a systematic method for determining instruments has been considered as a problem for creating an efficient selection. Nowadays, decision making methods have been used widely in different sciences for optimal determination and selection. In this study, the Multi-Attribute Decision Making is applied by considering 9 criteria and categorisation of 8 groups of geotechnical instruments. Therefore, the Analytic Hierarchy Process and Multi-Criteria Optimisation and Compromise Solution methods are employed in order to determine the attributes' importance weights and to prioritise of instruments for embankment dams, respectively. This framework was applied for a rock fill with clay core dam. The results indicated that group decision making optimizes the selection and prioritisation of monitoring instruments for embankment dams, and selected instruments are reliable based on the dam specifications.

The AHP methodology compares criteria, or alternatives with respect to a criterion, in a natural, pairwise mode. AHP has been applied in a wide variety of applications multi objective decision making being just one. If a group of expert with different aspect, they need some way to revise expert group. We proposed the concatenation of expert to survey the AHP pairwise question for multi-attribute decision making. In this paper, we suggest a way to revise the expert's priorities in hierarch using concept of different group opinion.

산업이 발전함에 따라 도로 터널의 사이즈와 길이는 계속적으로 증가해 왔으며 그에 따른 터널에서의 리스크 또한 증가되었다. 도로터널에서 환기방식을 결정할 때는 다양하고 많은 고려사항을 염두에 두어야 한다. 현재로서는 이러한 것들을 체계적으로 고려하여 의사결정을 지원할 수 있는 방법론 내지 시스템이 제대로 구축되어 있지 않은 실정이며 대부분 전문가의 경험을 바탕으로 한 주관적 판단에 의존하고 있다. 본 연구에서는 기존의 경제성 내지 주관적 판단에 국한하여 의사결정이 이루어지던 관행에서 벗어나 안전성, 환경친화성 등도 충분히 고려하여 결정을 내릴 수 있도록 터널별 최적의 환기방식을 선정하기 위한 일련의 절차와 기준을 제시하였다. 이 때 다속성 효용이론과, AHP기법을 적절히 활용하여 전문가 및 설계자의 주관적/정성적 평가를 객관적/정량적으로 측정할 수 있도록 하였으며, 환기 방식별 종합적 효용을 산출할 수 있는 함수를 도출하기까지의 방법론을 제시하였다. 본 논문에서 제시하는 방법론을 바탕으로 보다 합리적인 의사결정이 이루어질 것을 기대한다.

Weapon system currently considers the research about effect analysis including cost effectiveness methodology for a budget management and an achievement of the military strategy goal. So that, this study considers the theoretical background, strength and weakness of several Multi-Criteria Decision Making, and an effect analysis of weapon system. And AHP(Analytic Hierarchy Process) is selected for the best effect analysis methodology of weapon system. Therefore, we applied AHP to the case study of the new generation Multiple Launcher Rocket System, performing the analysis of cost effectiveness methodology. Using AHP and cost effectiveness methodology, we propose the actual and proper decision making result.

Recently, to design dynamic networks without existing infrastructure, wireless ad hoc networks have been proposed to establish self-organizing networks. In this type of network, to resolve the primary research challenge of establishing a stable path between source and destination, several metrics or utility values have been proposed to meet the specific objectives, as well as improve packet delivery ratio when developing communication protocols or addressing technical issues. Notably, most existing studies use the Multi Attribute Decision Making (MADM) algorithm to balance weights between relevant metrics to realize the above objective. However, despite their significant efforts, a comprehensive survey paper analyzing them together has not been published. Thus, in this paper, we describe the recent research and development efforts to employ MADM in ad hoc networks. First, we provide an overview of MADM and explain the well-known algorithms. After categorizing the current work according to the algorithms, the existing schemes are further divided by the type of networks. Based on this classification, we then detail the procedures with their research objectives. Furthermore, we present other research challenges and apparent problems in this research area.
