건설공사의 공사 초기단게에서 총 공사기간과 공사비용의 예측은 매우 중요하다. 터널공사는 공기가 길고, 복잡한 공정이 반복적으로 이루어지는 건설공사의 일종이다. 시뮬레이션은 효과적인 건설공사 관리를 위하여 공사 장비 및 자재 등의 적절한 조합을 고려하고, 현장에 적합한 프로세스를 구성하여 실제 공사에 미칠 영향을 예측하고 분석할 수 있는 기법이다. 본 연구에서는 NATM공법으로 시공되는 양방향 도심지 지하철 터널공사에서 발파시간 등의 제한사항을 고려한 모델을 Arena 시뮬레이션을 이용하여 개발하였다. 개발된 모델은 비쥬얼베이직을 이용하여 쉽게 사용할 수 있는 형태로 개발되었으며, 결과값으로 총 공사기간과 공사비용을 얻을 수 있다. 이 결과를 이용하여 공사 초기 단계에서의 의사결정 도구로서 사용될 수 있을 것이다.

Development of human-system interfaces (HSI) supporting the interaction between human and automation-based systems, particularly safety-critical sociotechnial systems, entails a wide range of design and evaluation problems. To help HSI designers deal with these problems, many methodologies from traditional human-computer interaction, software engineering, and systems engineering have been applied; however, they have been proved inadequate to develop cognitively well engineered HSI. This paper takes a viewpoint that HSI development is itself a cognitive process consisting of various decision making and problem solving activities and then proposes a design requirements-driven process for developing HSI. High-level design problems and their corresponding design requirements for visual information display are explained to clarify the concept of design requirements. Lastly, conceptual design of software system to support the requirements-driven process and designers' knowledge management is described.

Company A's core competency is IT internet security services. The Web diagnosis team analyzes the vulnerability of customer's internet web servers and provides remedy reports. Traditionally, Company A management has utilized a simple table format report for resource planning. But these reports do not notify the timing of human resource commitment. So, upper management asked its team leader to organize a task team and design a visual dashboard for decision making with the help of outside professional. The Task team selected the web security diagnosis practice process as a pilot and designed a dashboard for performance evaluation. A structural design process was implemented during the heuristic working process. Some KPI (key performance indicators) for checking the productivity of internet web security vulnerability reporting are recommended with the calculation logics. This paper will contribute for security service management to plan and address KPI design policy, target process selection, and KPI calculation logics with actual sample data.

Users' demands on the space are changing in variety. These demands include reasonable space and form, harmonious composition with surroundings and esthetic satisfaction that could be brought by personal tastes and preferences. In addition, models that are introduced from designing process and from various forms tend to lack objective decision making standard. Accordingly it is difficult to find a clear alternative plan and process. In an effort to solve these problems, the objects of this study are; to propose an analysis model of image and space by using image process techniques that are on study in the field of artificial intelligence based on acquisition of digital image and to verify the application possibilities of such analysis model, 'Isovist' on quantitative analysis. The model can be applied with variable analysis model, as digital image process and other analysis model such as 'Isovist' It is possible that further study can complement problems from this study.

Since world container throughput continues to grow, the main issues facing decision-makers at port container terminals are how to expand the existing container terminals and construct new container terminals. Simulations can be used in the decision making process tools due to its ease and ability to reflect the real world system. The object-oriented approach provides for both reusability and modularity that best fits these requirements. In this paper, the object-oriented approach to modeling and simulating general container terminals is presented. Simulation tools based on Visual C++ provide a user-friendly input and output environment through the use of an object class-library. This paper also presents the case study of a simulation of a real container terminal i. Pusan, Korea

Purpose - In the past, designs for traditional products have usually focused on historic techniques. However, this tradition of using historic techniques has now been replaced by the trend of using the innovative design concept. Research design, data, and methodology - To measure future market trends and quality requirements, we apply the results of the questionnaires and analyze them with various experimental processes and a design methodology. In this way, we gauge the impact of the innovative product value chain on the promotion of new products. Results - Accompanied with an innovative product value chain, the product can stimulate the development of enterprise management, which has become the main issue in social and economic development in every developed country, and can facilitate the progress of enterprise management throughout the enterprise. Conclusions - Customer demand should be emphasized as the primary means to solve design problems, to design optimal solutions, to create differentiation with competitors, and to pursue optimal marketing strategies.

최근에 비즈니스 인텔리전스 분야에서 비주얼 애널리틱스의 중요성이 강조되고 있다. 비즈니스 인텔리전스 관점에서 비주얼 애널리틱스는 다양한 관점의 비즈니스 관련 정보를 인터랙티브한 형태로 시각화함으로써 의사결정에 유용한 인사이트들을 획득하는 것을 목표로 한다. 본 논문에서는 트리맵을 이용하여 비즈니스 프로세스 수행자들간의 업무공유 관계들을 시각화하는 방법을 제안한다. 업무공유 관계는 비즈니스 프로세스의 특정 단위 업무에 공통적으로 참여하는 두 수행자간에 형성되는 연결 관계로서, 프로세스 기반 조직의 구조 및 행동 패턴을 이해하는 데에 중요한 요소이다. 이를 위해, 비즈니스 프로세스의 기본적인 계층적 정보와 수행자간 업무공유 관계를 트리맵의 형태로 나타내는 시각화 도구를 설계 및 구현하였다. 최종적으로 XPDL (XML Process Definition Language) 프로세스 모델을 이용한 실행 예제를 통해 시각화 도구의 유용성을 검증하였다.

Architecture should deviate from euclidean ideas of abstract space while helping to accommodate individual perceptions and experiences of a given space. Concepts for making space should be cognitively processed. The process of gathering information from the environment represents a new spatial concept as expressed in the cognitive structural relationship between the environment and the individual as the subject of architecture. Additionally, the cognitive experience of space is primarily perceived visually, and visual perception is the basis for information-gathering and decision-making. Therefore architecture should be excluded from the conceptual focus on the existing space design rules, being expressed instead in experimental architectural spaces connected to subjective human experience. While some research has been done on this topic regarding architecture, further study is required in the area of interior design. This study proposes the possibility of composing effective living space through an investigation of cognitive space concept theory and expression elements, and includes a case study of Interior architectural spatial analysis.

Hybrid robust image processing algorithm to extract visual features of melon during the cultivation was developed based on a wireless tele-operative interface. Features of a melon such as size and shape including position were crucial to successful task automation and future development of cultivation data base. An algorithm was developed based on the concept of hybrid decision-making which shares a task between the computer and the operator utilizing man-computer interactive interface. A hybrid decision-making system was composed of three modules such as wireless image transmission, task specification and identification, and man-computer interface modules. Computing burden and the instability of the image processing results caused by the variation of illumination and the complexity of the environment caused by the irregular stem and shapes of leaves and shades were overcome using the proposed algorithm. With utilizing operator's teaching via LCD touch screen of the display monitor, the complexity and instability of the melon identification process has been avoided. Hough transform was modified for the image obtained from the locally specified window to extract the geometric shape and position of the melon. It took less than 200 milliseconds processing time.
