대형복합건설사업에서 생성되는 정보들은 장기간의 사업주기를 걸치며 다양한 사업주체간에 이동하며 변환 및 발전된다. 그래서 지연 등 사업수행에 문제가 발생하였을 때, 문제의 원인은 해당 업무가 아니라 그 업무와 관련된 이전 업무일 경우 정보흐름을 거슬러 올라가며 문제의 원인을 분석해야 한다. 그러나 복잡한 사업주체 및 업무들의 관계 때문에 사업에서 생성되는 정보들이 어떻게 흘러가는지에 대해 기존의 키워드검색방법으로는 이러한 정보흐름을 도출하기에는 적합하지 않다. 이에 본 연구에서는 대형복합건설사업의 정보흐름을 분석하기 위한 관계기반 정보검색기능을 구축하고 이를 사례 정보시스템에 적용하였다. 우선 기존 정보검색시스템의 활용동향과 대형복합건설사업의 특성을 분석하여 정보전달관계 검색시스템의 필요성을 도출하였고, 이에 적합한 시스템 구축 방법론 및 업무 간 관계 추론 알고리즘을 정립하였다. 그리고 구축한 시스템을 사례시스템인 도시재생사업의 업무정보시스템에 적용하여 그 활용방안을 제시하였다. 본 연구에서 제시한 정보흐름검색은 업무를 담당하는 주체 및 총괄 관리자가 사업 전체를 원활히 진행시키기 위한 주요 업무 도출 등에 이용할 수 있으며, 추가연구의 도구로서도 활용될 것으로 기대된다.

In a super-highrise residence project, a project manager needs to form the long-term risk management plan which covers the problems from the beginning of project to the time of demolition. The cause and responsibility for a risk are clarified and quantitatively evaluated through the life cycle of a project. Development of the system which supports a risk strategy effectively is needed as a project becomes complex. In this paper, through the life cycle of a specific super-highrise residence project, a risk phenomenon is specified from a viewpoint of each participant, and the mathematical model is formulated choosing the combination of the optimal strategy against a risk quantitatively within a fixed risk strategy budget.

Assessement of comsolidation characteristics of soft soil is very important in the project of soft soil improvement. In the design step, the consolidation characteristics of soil is determined by the laboratory tests (typically oedometer test), generally. But there is big differences between the condition of laboratory test and the condition of field(in situ). the differences results in the considerable difference between the predicted and measured consolidation behavior. This article analyzed the consolidation data of the "SOFT SOIL IMPROVEMENT PROJECT of the 2nd Namdong Industrial Complex at Inchon". The project was improving the road way net work in the 2nd Namdong Industrial Complex by preloading and sand pile method. Field instrumentation was performed at 10 points which consist of pneumatic piezometers, magnetic probe extensometers, inclinometers and electronic dipmeter. The results showed that there is big difference in the laboratory predicted consolidation behavior and field consolidadion behavior. Also there was big difference in the settlement behavior and pore pressure behavior. This article investigated the above factors by comparing the settlement, pore pressure and strength at different conditions.onditions.

Recently, intensive urban redevelopment concentrated on new towns has reduced the number of settled population, and weakened various functions such as commercial, culture, education and welfare in old towns, and made the stagnation and declination of the entire or some parts of old towns. Urban regeneration project means renewing cities' functions in terms of physical, environmental, social, cultural, industrial and economic aspects or revitalizing the existing functions through improvement project in the entire or part of a city, which is now drawing keen attention from the public. However, urban regeneration project is huge in scale, needs long construction period and various complex facilities, and also characterized by complicated relations with many stakeholders. Due to such characteristics, there are many risks in the project. Therefore, systematic risk management is absolutely necessary to efficiently manage various risk factors inherent in urban regeneration project. The purpose of this research proposes a basic model to establish risk management plan and work process in order to help project participants to perform risk management more systematically and rationally in the development phase of urban regeneration project.

Network optimization is being increasingly important and fundamental issue in the fields such as engineering, computer science, operations research, transportation, telecommunication, decision support systems, manufacturing, and airline scheduling. Networks provide a useful way to modeling real world problems and are extensively used in practice. Many real world applications impose on more complex issues, such as, complex structure, complex constraints, and multiple objects to be handled simultaneously and make the problem intractable to the traditional approaches. Recent advances in evolutionary computation have made it possible to solve such practical network optimization problems. The invited talk introduces a thorough treatment of evolutionary approaches, i.e., hybrid genetic algorithms approach to network optimization problems, such as, fixed charge transportation problem, minimum cost and maximum flow problem, minimum spanning tree problem, multiple project scheduling problems, scheduling problem in FMS.
