본 연구에서는 소비자의 부하를 반영하여 실시간 전력품질을 평가할 수 있도록 하는 방법을 개발하였다. 이를 위하여 전력품질 상태를 [Ideal], [Measured], [Acceptable]로 분류하고, Ideal AHP를 사용하여 측정값이 어느 정도인지를 평가할 수 있도록 하였으며, 소비자 부하특성을 반영할 수 있도록 부하를 저항부하, 전동기부하, 전자제품부하로 분류하고 부하의 특성을 반영한 전력품질을 평가할 수 있도록 하였다. 향후, 1:1 행렬과 관련한 심도 있는 연구를 진행하고, 연간단위의 전력품질과 통합하여 종합적인 전력품질 평가를 할 계획이다.

Multiple attribute for decision making including user preference will increase the complexity of route selection process. Various approaches have been proposed to solve the optimal route selection problem. In this paper, multi attribute decision making (MADM) algorithms such as Simple Additive Weighting (SAW), Weighted Product Method (WPM), Analytic Hierarchy Process (AHP) method and Total Order Preference by Similarity to the Ideal Solution (TOPSIS) methods have been proposed for acoustic signature based optimal route selection to facilitate user with better quality of service. The traffic density state conditions (very low, low, below medium, medium, above medium, high and very high) on the road segment is the occurrence and mixture weightings of traffic noise signals (Tyre, Engine, Air Turbulence, Exhaust, and Honks etc) is considered as one of the attribute in decision making process. The short-term spectral envelope features of the cumulative acoustic signals are extracted using Mel-Frequency Cepstral Coefficients (MFCC) and Adaptive Neuro-Fuzzy Classifier (ANFC) is used to model seven traffic density states. Simple point method and AHP has been used for calculation of weights of decision parameters. Numerical results show that WPM, AHP and TOPSIS provide similar performance.

현재 개별공시지가를 산정하는 과정에서 비교표준지를 선정하는 작업은 지적 담당공무원의 수작업에 의하여 이루어지고 있다. 한정된 시간에 많은 개별필지의 비교표준지 선정 작업으로 인하여, 객관적이고 합리적으로 비교표준지를 선정하기에는 어려움이 있다. 또한 현재 NGIS(국가지리정보체계)나 US(도시정보체계)등에 의한 국가적인 지형정보체계 구축사업이 급속도로 진전되고 있다. 이에 따라 토지의 가치평가의 한 분야인 개별토지의 지가산정 작업도 최신의 자동화된 방법을 적용할 필요성이 증대되고 있다. 따라서, 본 연구에서는 공간 다기준 의사결정 방법 중에서 AHP, Concordance, Ideal Point 방법을 이용하며 비교표준지를 자동으로 선정하였다. 세 가지 방법을 적용하여 나온 결과를 현재의 비교표준지와 비교하여본 결과, Ai)p 방법이 가장 현실성이 있는 대안으로 선정되었다. 본 연구의 결과와 현재 사용중인 비교표준지를 연계하여 이용한다면 좀더 객관적이고 합리적인 비교표준지 선정이 이루어질 것으로 기대한다.

Nowadays, green purchasing, stop global warming, love the mother earth, and others that related to environment become hot issues. Manufactures industries tend to more active and responsive to those issues by adopting green strategies or program like Environmentally Conscious Manufacturing (ECM). In this article, an electronic company had applied 12 ECM Program and tries to choose one of those programs using 6 criteria, such as total cost involved, quality, recyclable material, process waste reduction, packaging waste reduction, and regulation compliance. By using multi-criteria decision making model, i.e. Analytical Hierarchy Process (AHP), Technique for Order Preference by Similarity to Ideal Solution (TOPSIS), and Modified TOPSIS methods, the ECM Program 9 (Open pit) is the best option.

본 연구는 퍼지 TOPSIS법과 AHP법을 이용하여 IMO 정보관리시스템의 예비과제 우선순위를 평가하기 위한 것이다. 이러한 평가를 위해 먼저 24개의 예비과제를 추출하여 FSM법을 이용하여 대체안을 구조화하였고, 최종 4개의 주요 예비과제를 도출한다. 또한 평가항목간의 가중치는 의사결정자의 일관성을 유지하면서 평가가 가능한 AHP법을 이용한다. 그러나 AHP법은 비교대상의 수가 증가하면 쌍대비교의 횟수가 증가하고, 평가에는 수많은 애매성이 존재하기 때문에 최종 우선순위 선정에는 TOPSIS에 퍼지이론을 도입한 퍼지 TOPSIS법을 이용한다. 그 결과 IMO 기준정보관리, IMO 정보기준전달, IMO 통합데이터베이스, IMO 지식허브 순으로 구축되어야 하는 것으로 나타났다.

Multi-criteria stock selection is a critical issue for effective investment since the improper stock investment might cause many problems affecting investors negatively. Investors need a range of financial indicators while they are choosing the optimal set of stocks to invest. This study aims to rank the stock of agriculture companies indexed on the Vietnam Stock Exchange Market. The data of 13 agriculture companies during the 2016-2019 periods was analyzed by analytical hierarchy process (AHP) integrated with grey relational analysis (GRA), multi-objective optimization ratio analysis (MOORA), and technique for order performance by similarity to ideal solution (TOPSIS). The AHP method is employed to determine the weights of the proposed financial ratios, and GRA, TOPSIS, and MOORA approaches are used to obtain final ranking. The results indicated that HSL is the top stock with the highest rank and GRA, MOORA, and TOPSIS rankings have strong correlation values between 0.78-1. The findings suggest that the integrated model could be implemented effectively to specific analysis of industries such as oil and gas, textiles, food, and electronics in future research. Further, other techniques like COPRAS, KEMIRA, and EDAS could be employed to evaluate the financial performance of other companies to solve investment problems.

현대의 무기체계는 복잡한 체계로 구성되어 있기 때문에 성능개량 요소의 우선 순위를 도출하는 것은 상당한 어려움이 있다. 또한, 이해관계자들의 의견을 고려한 정량적 성능개량 요소 우선순위 선정 방법론에 대한 연구도 미흡한 실정이다. 본 연구에서는 K1계열 전차와 K2전차의 성능개량 요소 우선순위를 정량적으로 도출하기 위해 전차 개발 경험을 보유한 전문가들을 대상으로 설문을 수행하고 AHP, 평점법, TOPSIS 기법을 이용하여 서문 데이터를 분석하고 분석 결과로 우선순위를 정량적으로 도출하였다. 본 연구의 결과는 향후 무기체계 개발 및 성능개량 단계에서 이해관계자들의 의사결정 지표로 활용될 것으로 기대된다.

A facility layout design (FLD) problem can be generally introduced as assignment of facilities (departments) to a site such that a set of criteria are satisfied or some objectives are minimized (maximized). Hence, it can be considered as a multi-criteria problem due to the presence of qualitative criteria such as maintenance or flexibility and quantitative criteria such as the total cost of handling material. The VIKOR method was developed to solve multiple criteria decision making problems with conflicting and non-commensurable (different units) criteria, assuming that compromising is acceptable for conflict resolution, the decision maker wants a solution that is the closest to the ideal, and the alternatives are evaluated according to all established criteria. This paper proposes a hierarchical analytic hierarchy process (AHP) and VIKOR approach to solve the FLD problem. A computer-aided layout-planning tool is adopted to generate the facility layout problems, as well as their quantitative data. The qualitative performance measures are weighted by AHP. VIKOR is then used to solve the FLD problem. Finally, the proposed integrated procedure is applied to three real-time examples.

Dispatching rule plays an important role in a hybrid flow shop. Finding the appropriate dispatching rule becomes more challenging when there are multiple criteria, uncertain demands, and dynamic manufacturing environment. Using a single dispatching rule for the whole shop or a set of rules based on a single criterion is not sufficient. Therefore, a multi-criteria decision making technique using 'the order preference by similarity to ideal solution' (TOPSIS) and 'analytic hierarchy process' (AHP) is presented. The proposed technique is aimed to find the most suitable set of dispatching rules under different manufacturing scenarios. A simulation based case study on a PCB manufacturing process is presented to illustrate the procedure and effectiveness of the proposed methodology.

In Korea, most of the historic city became a deteriorated area with low-rise settlement. It is revaluated as a s great potential in spite of slum clearance and redevelopment for a long while after 1970s. A great achievement for low rise multi family housing, in spite of these social change, is not easy to find the cases and social commonness. In the view points, this article deals a ideal model in historic areas, and the model should be get the understanding from the people, because acceptance from people is the beginning for making historic housing areas. The facade model for evaluation prepared as three types, and responses for the models processed by AHP(Analysis Hierarchy Process).
