생태산업단지의 산업 공생망 구성을 위한 다중척도 의사결정 전략을 개발하고 이를 여수산업단지의 산/염기성 폐수 중화망 설계에 적용하였다. 산(또는 염기)성 폐수는 화학산업에서 공통적으로 나오며, 다른 곳에서 나온 염기(또는 산)성 폐수를 자체적으로 중화할 수 있는 원료가 될 수 있다. 따라서 산/염기성 폐수가 대량으로 발생되는 석유화학산업단지에서 대규모의 산업 공생망을 구축할 수 있는 가능성을 지나고 있다. 본 연구에서는 산/염기성 폐수의 상호 중화를 위한 물질 흐름 모델을 구성하고, 여기에 다중척도의사결정 전략을 적용하여 최적이며 대등한 다수의 산업 공생망 후보를 설계하고 이들의 성능을 비교 분석하였다.

In this paper, a versatile multi-criteria optimization concept for fatigue life prediction is introduced. Multi-criteria decision making in engineering design refers to obtaining a preferred optimal solution in the context of conflicting design objectives. Compromise decision support problems are used to model engineering decisions involving multiple trade-offs. These methods typically rely on a summation of weighted attributes to accomplish trade-offs among competing objectives. This paper gives an interpretation of the decision parameters as governing both the relative importance of the attributes and the degree of compensation between them. The approach utilizes a response surface model, the compromise decision support problem, which is a multi-objective formulation based on goal programming. Examples illustrate the concepts and demonstrate their applicability.

웹상에서 이용할 수 있는 방대한 문서의 집합인 WWW은 사용자를 위한 다양한 정보의 보고이다. 그러나 불필요한 정보의 필터링이나 사용자가 필요한 정보를 검색하는데 많은 시간이 소요되어 효율적인 의사결정을 하는데 어려움이 있다. 본 논문에서는 의사결정에 관한 요소를 계층화 구조로 나타내는 AHP나 Fuzzy AHP방법들을 데이터의 관점에서 대안, 평가기준, 주관적 속성가중치, 개념과 객체 사이에 퍼지 관계를 기반으로 웹 자원을 효과적으로 관리하고 의사결정을 할 수 있는 EFAM(Extended Fuzzy AHP Method) 모델을 제안하였다. 제안한 EFAM 모델은 웹상의 효율적인 문서검색과 특정 영역의 문제를 의사결정하기 위하여 영역의 코퍼스로부터 추출된 개념들이 가지는 의미론적 내용에 감성 기준을 고려함으로써 효율적으로 문서를 추출할 수 있어서 명확한 의사결정을 할 수가 있음을 실험을 통하여 확인한다.

본 연구는 Fuzzy AHP기법을 의사결정의 방법론으로 이용하여 대형할인점의 입지선정을 위한 구조적이고 활용가능한 의사결정과정을 제시하고자 하였다. 이를 위해서 본 연구의 수행절차는 대형할인점의 입지선정을 위한 평가기준을 선정하여 평가기준간의 상대적인 가중치를 도출한 후, 사례대상지를 선정하고 입지를 실제로 평가하여 최적의 입지를 선정하는 두 단계로 구성된다. 평가기준간의 가중치에 있어서는 1차 상권인구가 가장 높은 가중치를 보였으며, 그 다음으로 경쟁업체수, 인접도로폭, 총인구수, 부지면적, 부지매입비의 순으로 가중치가 큰 것으로 나타났다. 또한 사례대상지인 대형할인점 부지 6개소의 입지현황을 파악하고 입지를 평가하여 최적의 입지를 도출함으로써 본 연구가 제시한 의사결정과정이 실제사례에 적용가능함을 입증하였다.

Analytical Hierarchy Process (AHP) is a famous method amongst Multi Criteria Decision Making (MCDM), set up by Saaty in 1980. AHP can be determined as a methodology of hierarchical analysis following reasonable decision making with make simpler a difficult crisis. Decision making in systems of Safety management concerned multipart challenges. AHP is process for get better the composite decisions understanding with analyzes of the problem in a structure of hierarchy. The integration all of applicable decision criteria, their pair wise judgment permits the decision maker to establish the trade-offs amongst objectives. In recent years, Malaysian's economy and infrastructure development have significantly and rapidly risen. The construction industry continues to play a major role in this development as many construction activities have been carried out to meet the high demands of the expansive market. However, the construction industry has faced a wide range of challenges, one of which is the frequent occurrences of accidents at the workplace. An effective safety program can substantially reduce accidents because it can help management to build up safer means of operations and create safe working environments for the workers. Furthermore, by having an effective safety programs, good safety culture can be embedded in organization because it can encourage mutual cooperation between management and workers in the operations of the programs and decisions that affect their safety and health. The focus of this research is development methodology of Analytics Hierarchy Process (AHP) in construction safety factors and investigates the levels of some effective elements in SMS in Malaysian construction industries.

The bearing design includes the steps of selection bering type, selection bearing subtype, and determining the peripheral equipments. In this paper decision making methodologies are compared to propose a stepwise decision methodology to the bearing selection problem. An artificial neural network trained with design cases is used for selecting a bearing type in the first step. Then the subtype of the bearing is selected using the weighting method, high is a kind of multi-criteria decision making method. Finally, the types of peripheral equipments such as lubrication devices, seals and bearing housings are determined using a rule-based expert system.

Recently organizations identify information security as one of essential means for gaining competitive advantage. However, they do not actively increase investment in this area because they consider spending for information security as a cost rather than an investment. This is because organizations don't have a clear understanding of information security objectives which can be achieved through investment, and they don't have criteria for alternatives which can be considered in information security investment decision-making. In this paper we propose to model the decision-making process of information security investment by the AHP (Analytic Hierarchy Process). The results will show that availability is the most important criterion for the decision of information security alternatives, and intrusion detection is the most important information security alternative. We hope that the results of this paper provide a guideline for clear decision-making in information security investment.

Purpose: This study examines the market segmentation and strategy of PT INKA, a rolling stock manufacturer in Indonesia. Research design, data and methodology: The study used the MCDM (Multiple Criteria Decision Making) method specifically the AHP (Analytical Hierarchy Process). The AHP method was applied to identify the target market. This method or approach considers the market attractiveness and competitive strength criteria with quantified parameters. Results: a) Australia, Kenya, Tanzania, New Zealand, and India emerge as the top five target markets; b) There is justification for rolling stock manufacturers to allocate their resources in winning the market share. Conclusion: The main challenge confronting the rolling stock manufacturer is limited resources to acquire a particular market share despite abundant opportunities in this sector. Despite the mastery of technology and long experience in the industry, selecting a target market with multiple criteria could be difficult for an emerging rolling stock manufacturer in South East Asia.

The purpose of this study is to identify adult learners' decision making variables, satisfaction, and evaluation toward fashion education as a university lifelong education program. As decision making variables, this study included participation purpose, information source, and selection criteria for lifelong education center and program. Regarding satisfaction toward fashion education, this study included satisfaction toward program and satisfaction toward education condition and administrative services. Data were gathered by both questionnaires and focus group interview(FGI) with 12 adults who completed the program. While questionnaires were used for decision making variables and satisfaction, FGI was used for evaluation. Frequency was used to analyze the questionnaires and content analysis was used to analyze the results of FGI. The findings showed that respondents participated mostly because of hobby or interest and got information mostly from acquaintances. They regarded program contents as the selection criteria for lifelong education center. They also regarded lecturers' professionality as the selection criteria for the program and showed high satisfaction toward lecturers' passion. Regarding education condition and administrative services, they showed high satisfaction. FGI also showed the importance of individual competence, career development, a work-study program, a on-site study program, and lecturer. The results suggest methods to make university lifelong education programs more appealing to adults who want to attend universities for non-degree university programs.
