Mathematical Programming Models for Establishing Dominance with Hierarchically Structured Attribute Tree

한창희,Han, Chang-Hee Military Operations Research Society of Korea 2002 한국국방경영분석학회지 Vol.28 No.2

This paper deals with the multiple attribute decision making problem when a decision maker incompletely articulates his/her preferences about the attribute weight and alternative value. Furthermore, we consider the attribute tree which is structured hierarchically. Techniques for establishing dominance with linear partial information are proposed in a hierarchically structured attribute tree. The linear additive value function under certainty is used in the model. The incompletely specified information constructs a feasible region of linear constraints and therefore the pairwise dominance relationship between alternatives leads to intractable non-linear programming. Hence, we propose solution techniques to handle this difficulty. Also, to handle the tree structure, we break down the attribute tree into sub-trees. Due to there cursive structure of the solution technique, the optimization results from sub-trees can be utilized in computing the value interval on the topmost attribute. The value intervals computed by the proposed solution techniques can be used to establishing the pairwise dominance relation between alternatives. In this paper, pairwise dominance relation will be represented as strict dominance and weak dominance, which ware already defined in earlier researches.

최근 군은 과거 냉전시대와 다른 상황에 능동적으로 대처하고 비용 대비 훈련의 효과를 극대화하기 위한 방안으로 모델링 시뮬레이션 기법에 많은 관심을 보이고 있다. 이 모델링 시뮬레이션을 이용한 훈련이 효과적이기 위해서는 좀 더 사실적인 전장 환경과 전투상황을 모의해야 하는데, 최근에 이를 위해서 컴퓨터상에서 인간 행위와 부대의 집단논리를 표현하는 CGF(Computer Generated Forces)에 대한 기술 개발이 주목받고 있다. 인간 행위를 모델링하는 CGF는 자동화된 병력을 모의함으로써 적군을 모의하거나 미래 전투실험, 새로운 전투개념 개발 등 중요하면서도 다양한 역할을 수행 할 수 있다. 이번 연구에서는 CGF 가상군인의 자율지능화의 방안을 고찰해보고자 한다. 군사시뮬레이션상의 가상군인의 자율지능화의 첫걸음인 과업행위 목록의 적용을 과업행위의 기본요소인 METT+T를 기반으로 그 적용과정을 설명한다. 또한 군사모의 논리는 참 진의 이진값 표현이 외에도 '보유 무기가 충분하면 급속 공격을 빠르게 하라'와 같은 모의 규칙상에서는 군사 전문가에 의해서 결정될 수밖에 없는 '충분하다', '빠르다'와 같은 퍼지 팩트가 존재한다. 이러한 주관성이 가미된 많은 군사모의 논리를 완벽히 표현하기 위해서는 퍼지 추론을 이용하는 것이 효과적인데, 이를 이번 소부대 전투 시뮬레이션에 적용하여 보다 사실적인 모의가 가능하도록 하였다. Modeling and Simulation(M&S) technology gets an attention from various parts such as industry and military. Especially, military uses the technology to cope with a different situation from the one in the Cold War and maximize the effect of training against the cost in the new environment. In order for the training based on M&S technology to be effective, the situations of a battlefield and a combat must be more realistically simulated. For this, a technique development on Computer-Generated Forces(CGF) which represents a unit's simulation logic and a human's simulated behaviors is focused. The CGF simulating a human's behaviors can be used in representing an enemy force, experimenting behaviors in a future war, and developing a new combat idea. This paper describes a methodology to accomplish Computer-Generated Forces' autonomous intelligence. It explains the process of applying a task behavior list based on the METT+T element onto CGFs. On the other hand, in the domain knowledge of military field manual, fuzzy facts such as "fast" and "sufficient" whose real values should be decided by domain experts can be easily found. In order to efficiently implement military simulation logics involved with such subjectivity, using a fuzzy inference methodology can be effective. In this study, a fuzzy inference methodology is also applied.

This paper presents characteristics of a virtual human's navigation using a limited perception-based mapping. Previous approaches to virtual human navigation have used an omniscient perception requiring full layout of a virtual environment in advance. However, these approaches have a limitation on being a fundamental solution for a human-likeness of a virtual human, because behaviors of humans are basically based on their limited perception instead of omniscient perception. In this paper, we integrated Hill's mapping algorithm with a virtual human to experiment virtual human's navigation with the limited perception. This approach does not require full layout of the virtual environment, 360-degree's field of view, and vision through walls. In addition to static objects such as buildings, we consider enemy emergence that can affect an virtual human's navigation. The enemy emergence is used as the variable on the experiment of this present research. As the number of enemies varies, the changes in arrival rate and time taken to reach the goal position were observed. The virtual human navigates by two conditions. One is to take the shortest path to the goal position, and the other is to avoid enemies when the virtual human encounters them. The acquired result indicates that the virtual human's navigation corresponds to a human cognitive process, and thus this research can be a framework for human-likeness of virtual humans.

B2B 전자상거래 보증 서비스는 신용보증기금과 은행, e마켓플레이스 간에 전산시스템을 연결하여 신용보증 신청에서부터 보증서 발급, 상거래 계약, 대금결제가 인터넷 상에서 이루어지는 보증 서비스를 말한다. B2B 전자상거래 보증 서비스는 대기업에 비해 상대적으로 규모가 작고, 신용도가 낮으며, 여러 면에 있어 불리한 상태에 있는 중소기업이 필요한 자금을 원활히 공급받을 수 있도록 매개역할을 하는 제도이다. B2B 전자상거래 보증 서비스의 다양한 장점에도 불구하고 인지도 부족과 전자보증에 대한 잘못된 이해, 온라인상에서 결제하는데 대한 막연한 심리적 불안감 등으로 인해서 빠른 확산이 이뤄지지 않고 있다. 따라서 본 연구에서는 B2B 전자상거래 보증 서비스의 효과 및 가치를 데이터와 사례들을 통해 분석해 보고자 한다. 이를 위해 B2B 전자상거래 보증 서비스 및 e-Marketplace에 대한 분석을 시작으로 서비스 이해관계자 별 성과항목 도출, 중소기업 지원 및 사회 경제적 성과 분석 등을 진행하였다. B2B e-commerce guarantee service is a guarantee service combining the electronic systems among Korea Credit Guarantee Fund(KCGF), banks and e-marketplaces to process all procedures on internet ranging from application for credit guarantee, issue of written guarantee and contracting for a commerce to payment. B2B e-commerce guarantee service plays as an intermediary role in financial support for small and mediumsized enterprise(SME), which are small size, low credit level, and unfavorable status in many aspects compared to major companies. Despite the B2B e-commerce guarantee service has various advantages conducive to promotion of e-commerce among small and medium businesses as well as development of e-commerce itself, it has yet to be diffused due to lack of acknowledgement, misunderstanding of its functions and vague psychological fear of the on-line settlement. Thus, this study identifies the values and effects of the B2B e-commerce guarantee service using financial data and cases. The process of this study is 4 phase. first phase is analysis of B2B e-commerce guarantee service and e-Marketplace. second phase is analysis of performance from the Perspective of Diverse Participants. third phase is analysis of economic performance and support for SME. last phase is policy suggestions and conclusion.

< UNBORN0x9 > : Multidimensional Exploration of Symbolic and Ethical Dimensions in the Era of Artificial Wombs and Posthuman Parturitions

한창희 ( Chang Hee Han ) 미래의료인문사회과학회 2023 FUTURE MEDICINE & HUMANITIES Vol.6 No.2

본 연구는 인공 자궁을 중심으로 한 상징적이고 윤리적 차원을 다룬 UNBORN0X9 프로젝트를 탐구한다. 이 프로젝트는 역사적 담론에서 현대 생식 기술의 전선까지 걸쳐 다양한 차원에서의 탐험으로 과학, 윤리, 사회적 가치가 교차하는 지점에 위치한 이 프로젝트는 특히 포스트휴먼 출산의 맥락에서 의학의 미래에 대해 성찰한다. UNBORN0X9 프로젝트는 상징적으로 전체 임신 과정을 포괄적으로 나타내며, 완전히 인간적이지 않고 아직 태어나지 않은 생명과 관련된 도덕적 고찰을 일으킨다. 태아의 도덕적 지위에 대한 계속되는 논쟁은 법적 뼈대, 과학적 발전 및 사회적 시각의 동적 상호 작용 내에서 검토 된다. 특히 인공 자궁의 등장은 기존의 경계를 도전하며 중점을 이끌어낼 수 있다. 본 연구는 1923년 J.B.S. Haldane로부터 촉발된 인공 자궁 논의의 역사적 기원이 현대 예술 작품에 어떻게 작용하는지 탐구하며, 생식 기술이 급격히 진화하는 환경에서 윤리적 고려의 영속적 중요성을 강조한다. 미래 의학의 맥락에서 인공 자궁은 기술적 경이뿐만 아니라 전통적 생식 패러다임 재정의의 상징으로 떠오른다는 점에서 본 연구는 윤리적 고찰에 전면적이고 연결된 접근이 필요하며, 자궁 외에서 유아를 유발하는 객체를 둘러싼 복잡한 관계와 가치를 인정한다. 사회가 자연과 인공 사이의 경계가 흐릿한 미지의 영역을 항해하는 상황에서 UNBORN0X9 프로젝트는 자연과 인공 사이의 경계에서 적절한 윤리적 고려를 요구한다. This study delves into the UNBORN0X9 project, providing a multidimensional exploration of the symbolic and ethical dimensions surrounding the artificial womb. Spanning historical discourse to the forefront of contemporary reproductive technologies, the project is positioned at the intersection of science, ethics, and societal values. It serves as a catalyst for profound reflections on the future of medicine, particularly in the context of posthuman parturitions. The UNBORN0X9 project symbolically encapsulates the entire gestational journey, prompting a nuanced examination of moral considerations associated with entities not yet fully human and unborn. The ongoing debate on the moral status of the unborn is scrutinized within the dynamic interplay of legal frameworks, scientific advancements, and shifting societal perspectives. Particularly, the emergence of artificial wombs challenges existing boundaries and introduces a new layer to the discourse surrounding the right to abortion. The historical roots of the artificial womb discourse, dating back to J.B.S. Haldane's visionary lecture in 1923, provide a backdrop for understanding the evolution of societal perspectives on ectogenesis. This study explores how the echoes of a century-old debate linger in the contemporary narrative, emphasizing the enduring significance of ethical considerations in the rapidly advancing landscape of reproductive technologies. In the context of future medicine, the artificial womb emerges not only as a technological marvel but as a symbol of the redefinition of traditional paradigms of reproduction. The study concludes by emphasizing the necessity for a holistic and interconnected approach to ethical deliberations, acknowledging the intricate tapestry of relationships and values that surround entities gestating ex utero. As society stands at the crossroads of scientific progress and moral responsibility, the UNBORN0X9 project calls for thoughtful and deliberate ethical considerations to navigate the uncharted territories where the boundaries between the natural and the artificial blur.

The introduction and application of IT(Information Technology) to a company has become to be viewed as a key factor for the business competitiveness and improved productivity. This study presents an approach to evaluation of a company's informatization level, which is especially appropriate for small and medium enterprises. The proposed evaluation method, based on the traditional questionnaire approaches, considers the various characteristics of the company, e.g., types of business, characteristics of customers, and locations of supply chains etc. A web-based system was developed to enable users to obtain the evaluation results from the evaluation method. The system also provides a function to produce valuable strategies for informatization by utilizing the case base which will be cumulated by repetitive evaluation requests. Finally, a real case was analyzed in order to verify the practicality of the evaluation system.
