  • 인공지능에 기반한 지능형 지휘통체체계는 복잡하고 방대한 전장정보와 전술 데이터들을 학습모델을 통해 자동으로 융합 및 추출하여 전장상황을 분석한다. 지휘관은 지능형 지휘통제체계의 상황분석 결과를 제공받아 전장인식이 가능하여 의사결정을 지원할 수 있다. 의사결정지원에 특화된 결과를 지휘관에게 제공하기 위해서는 인공지능을 학습하기 위한 실 전장상황과 유사한 전장상황분석 데이터셋 생성이 필요하다. 본 논문은 기존 선행연구인 '인공지능 기반 전장상황분석을 위한 가상 전장상황 데이터 셋 생성 연구'의 다음 단계의 데이터셋 구축 방법 연구로 지휘관의 의사결정지원 및 미래 전장인식을 위해 최종적인 전장상황분석 결과에 필요한 데이터셋을 생성하는 방안에 대해 제안하였다. 전장상황 분석용 학습 데이터셋 생성도구 SW를 설계 및 구현하였고, 구현한 SW를 이용하여 데이터 레이블 작업을 진행하였다. Siamese Network 학습모델을 이용하여 구축한 데이터셋을 입력하고, 후처리 알고리즘을 활용한 출력 결과를 도출하여 생성한 데이터셋을 검증하였다.

  • 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.

  • A ship's sailing route or plan is determined by the master as the decision maker of the vessel, and depends on the characteristics of the navigational environment and the conditions of the ship. The trajectory, which appears as a result of the ship's navigation, is monitored and stored by a Vessel Traffic Service center, and is used for an analysis of the ship's navigational pattern and risk assessment within a particular area. However, such an analysis is performed in the same manner, despite the different navigational environments between coastal areas and the harbor limits. The navigational environment within the harbor limits changes rapidly owing to construction of the port facilities, dredging operations, and so on. In this study, a support vector machine was used for processing and modeling the trajectory data. A K-fold cross-validation and a grid search were used for selecting the optimal parameters. A complicated traffic route similar to the circumstances of the harbor limits was constructed for a validation of the model. A group of vessels was composed, each vessel of which was given various speed and course changes along a specified route. As a result of the machine learning, the optimal route and voyage data model were obtained. Finally, the model was presented to Vessel Traffic Service operators to detect any anomalous vessel behaviors. Using the proposed data modeling method, we intend to support the decision-making of Vessel Traffic Service operators in terms of navigational patterns and their characteristics.

  • 본 연구에서는 계층분석과정에 대한 노선 선정에 요구되는 자료들을 추출 및 이용하여 합리적인 노선 선정의 방법을 제시하였다. 선정된 노선의 결과를 GIS를 이용하여 시각화 및 분석하였으며, 종단선형을 고려한 선형 프로그램을 개발 및 구축하였다. 이러한 연구를 요약하면 GIS 기반의 계층분석과정을 응용하여 생성된 노선을 기준으로 기존 노선의 적정성에 대한 평가를 정량적으로 할 수 있었으며, 신설될 노선에 적용하면 도로 계획 및 기본 설계에 객관적이고 신뢰성 있는 노선의 평가를 할 수 있었다. 기존의 2차원적 정보에 의한 의사결정시스템에서 종단계획까지 고려한 3차원 정보에 의한 의사결정시스템을 적용함으로서 노선 선정기법을 향상시켰고 종단경사, 토공량, 구조물 규모와 위치, 공사비 등의 정보를 독립 변수로 할 수 있으므로 더욱 과학적이고 합리적으로 도로 설계를 할 수 있었다.

  • Purpose: Long-life housing causes unavoidable cost increase while providing higher durability, flexibility, and repair easiness compare to those of normal apartment. The effectiveness should be evaluated considering the level of passing mandatory Long-life housing Certification System when supplying specific size of apartment complex. Thus, it is essential to identify the estimated costs and the obtainable grade by applying the optional element technologies selectively during the design phase. This study aimed to suggest the technology influence matrix(TIM) to support decision-making of element technologies in planning stage of long-life housing. Method: The technology influence matrix was established based on the property information about applicable element technologies for long-life housing such as construction methods, interface types, cost data, and certification-related characteristics. The usefulness of TIM was verified through case study, in which TIM was applied to the exclusive housing unit and the influences from four areas of quantity, cost, certification, and schedule were identified and calculated. Result: TIMs covering four areas representing the essential planning factors were developed, and are expected to contribute to sound decision-making in planning long-life housing.

  • Background: Decision making modalities for screening for many cancer conditions and different stages have become increasingly complex. Computer-based risk assessment systems facilitate scheduling and decision making and support the delivery of cancer screening services. The aim of this article was to survey electronic risk assessment system as an appropriate tool for the prevention of cancer. Materials and Methods: A qualitative design was used involving 21 face-to-face interviews. Interviewing involved asking questions and getting answers from exclusive managers of cancer screening. Of the participants 6 were female and 15 were male, and ages ranged from 32 to 78 years. The study was based on a grounded theory approach and the tool was a semi-structured interview. Results: Researchers studied 5 dimensions, comprising electronic guideline standards of colorectal cancer screening, work flow of clinical and genetic activities, pathways of colorectal cancer screening and functionality of computer based guidelines and barriers. Electronic guideline standards of colorectal cancer screening were described in the s3 categories of content standard, telecommunications and technical standards and nomenclature and classification standards. According to the participations' views, workflow and genetic pathways of colorectal cancer screening were identified. Conclusions: The study demonstrated an effective role of computer-guided consultation for screening management. Electronic based systems facilitate real-time decision making during a clinical interaction. Electronic pathways have been applied for clinical and genetic decision support, workflow management, update recommendation and resource estimates. A suitable technical and clinical infrastructure is an integral part of clinical practice guidline of screening. As a conclusion, it is recommended to consider the necessity of architecture assessment and also integration standards.

  • 육군전술지휘정보체계(ATCIS)에서는 군단급 이하의 전술제대들로부터 입력받은 전장정보를 부대 지휘관과 참모들에게 제공하며, 이를 바탕으로 지휘관은 자신의 야전 경험과 군사 전문성을 활용하여 지휘 결심을 하게 된다. 만약 급격하게 변화하는 전장 상황에서 ATCIS가 입력 받은 적 또는 전장 상황에 대한 정보의 의미를 자동으로 이해하여 지휘 결심에 도움을 줄 수 있는 새로운 지식을 제공할 수 있다면, 지휘관은 좀 더 빠르고 정확한 의사결정을 할 수 있게 될 것이다. 따라서 본 연구에서는 국방온톨로지를 활용한 지능형 ATCIS를 제안하고자 한다. 이를 위해, 전자 교범과 ATCIS 데이터베이스 정보를 분석하여 국방온톨로지를 구축하였고, 부대 참모들의 인터뷰를 통하여 지휘 결심에 필요한 군사지식을 규칙 형태로 정의하였다. 또한 구축된 국방온톨로지와 규칙이 지휘관의 의사결정지원에 활용되는 것을 보이기 위해 시맨틱 웹 기술을 활용하여 적의 도발 가능성을 예측하는 서비스를 구현하였다.

  • This paper presents a multi-agent system for intelligent recommendation of travel plans to users. The goal of the system is to provide alternative and preferable travel plans to users when the availability of tickets is low such as in vacations, holidays, weekends, or peak seasons. The multiple agents in the system search for available alternatives for a target travel in collaboration with other agents and recommend best alternatives by analyzing them using a multi-criteria decision-making model. A prototype online travel support system was constructed and a simulation experiment was performed for evaluation and comparison with different travel planning strategies.
