The cooperation and trust among the project participants play a critical role in the success or failure of any delivery system in construction industry. But it is very difficult to establish trust between an owner and a contractor when rational people only pursue only their own material self-interest. Based on the principal-agent theory, this paper will introduce the altruistic behavior into the traditional principal-agent model, and model the reciprocal behavior between the owner and contractor. We will show that both the owner and the contractor benefit from their reciprocal behavior, and hence trust establishing between them is possible. More importantly, we will proof that the higher the project uncertainty is, the more important trust establishing is.

Although the evolution and deployment of information technologies will undoubtedly play an important role in the current construction industry, many engineers are still unsure of the economic value of using these technologies. Especially for the planning of a construction project, a collaboration system to utilize the whole resources is a essential tool for the successful outcome. A detailed, authoritative, and readily accessible information model is needed to enable engineers to make cost-effective decisions among established and innovative plan alternatives. Most engineers rely on limited private experiences when they create solutions or design alternatives. Initial planning is crucial for the success of the construction project. Most construction projects are done through collaboration of engineers who have different specialized knowledge. Information technologies can dramatically enhance the performance of the collaboration. For the information delivery, we need a mediator between engineers. Object-based 3-D models are useful for the communication and decision assistance for the intelligent project design. In this paper, basic guidelines for the 3-D design according to different construction processes are suggested. Adequate interoperability of 3-D objects from any CAD system is essential for the collaboration. Basic architectures of geometry models and their information layer were established to enable interoperability for design checks, estimation and simulation. A typical international project for roadway was chosen for the pilot project. 3-D GIS model was created and bridge information models were created considering several requirements for planning and decision making of the project. From the pilot test, the integrated construction project planning using 3-D information models was discussed and several guidelines were suggested.

The objective of this paper is to develop an evaluation model for pilot informatization projects. There are relatively many researches on evaluation models for information systems. These previous researches, however, lack of comprehensive view of informatization Projects and pilot systems. We apply and test a hybrid evaluation model for to measure the success of pilot informatization projects. A user satisfaction model has been used and hypotheses are developed to find relationships of evaluation factors. The hypotheses have been tested with 51 user surveys. The result of this research can give an insight for the evaluation of pilot informatization projects.

본 논문에서는 FSM을 이용하여 기업프로젝트의 성공요인에 대한 의식구조를 분석한다. FSM은 ISM에 퍼지이론을 도입한 것으로서 다원적 가치가 복합되어 있는 시스템의 구조 인식에 보다 유효하다고 알려져 있으며, parameter p와 $\lambda$에 의해 변화되는 구조모형을 현실에 맞는 것으로 선택하도록 되어있다. 이것은 구조모형으로서의 객관적인 적합성평가를 실시하지 않은 상태에서 선택하는 것이기 때문에 선택된 구조모형이 현실에 적합하다고 판단된다 하더라도 보완적인 차원에서 구조 모형의 적합성평가를 실시하는 것이 바람직하다고 할 수 있다. 따라서 본 논문에서는 FSM을 이용하여 구한 기업프로젝트 달성을 위한 성공요인에 대한 구조모형에 대하여 구조방정식 모형분석을 이용한 적합성을 평가하여 보다 객관성 있는 구조모형을 제시하고 그 구조모형에 따라 의식구조를 분석한다.

건설업은 일반 제조업의 생산과정과는 달리 다양한 참여주체들이 모여 프로젝트 성공이란 하나의 목표아래 정보를 공유하며 업무를 진행하므로 한 프로젝트마다 일시적인 팀워크가 형성된다. 다양한 참여주체들은 건설공사의 단계별 역할이 다르며, 업무 및 이에 따른 이해관계 역시 복잡하게 얽혀있다. 건설프로젝트의 효율적인 관리와 경영의 최적화를 위하여 CM제도가 도입이 되었다. 따라서 CM제도의 성공을 위해서는 주요 참여주체(발주자, CMr, 설계자, 시공자)의 협력관계가 요구된다. CM제도가 도입된 이래 성공적으로 사업을 수행하기 위한 일환으로 CM성과측정에 대한 많은 노력이 있었으나, 발주자의 입장에서만 바라본 항목으로 측정되고 있다. 이에 본 연구에서는 CM성과를 객관적으로 측정하기 위해서 건설프로젝트의 주요 참여주체인 발주자, CMr, 설계자, 시공자의 균형적인 시각을 바탕으로 한 성과측정 항목의 필요성을 제기 하고자 한다. 건설프로젝트의 주요 참여주체인 4자(발주자, CMr, 설계자, 시공자)의 협력관계를 살펴본 뒤 각 주체에 따라 성과항목에 대한 인식차이가 있다는 것을 검증하였다.

This paper presents a study conducted with the aim of developing a model of tendering based on a technique of artificial intelligence by managing and controlling the factors of success or failure of construction projects through the evaluation of the process of invitation to tender. Aiming to solve this problem, analysis of the current environment based on SWOT (Strengths, Weaknesses, Opportunities, and Threats) is first carried out. Analysis was evaluated through a case study of the construction projects in Algeria, to bring about the internal and external factors which affect the process of invitation to tender related to the construction projects. This paper aims to develop a mean to identify threats-opportunities and strength-weaknesses related to the environment of various national construction projects, leading to the decision on whether to continue the project or not. Following a SWOT analysis, novel artificial intelligence models in forecasting the project status are proposed. The basic principal consists in interconnecting the different factors to model this phenomenon. An artificial neural network model is first proposed, followed by a model based on fuzzy logic. A third model resulting from the combination of the two previous ones is developed as a hybrid model. A simulation study is carried out to assess performance of the three models showing that the hybrid model is better suited in forecasting the construction project status than RNN (recurrent neural network) and FL (fuzzy logic) models.

In the paper, we proposed the systematical and quantitative software risk management methodology based on risk analysis model. A software risk management consists of the basic risk management method(BRIMM) and the detailed risk management method(DRIMM). BRIMM is applied to unimportant phases or the phase which also the risk factor does not heavily influence to project. DRIMM is used from the phase which influences highly in project success or the phase where the risk factor is many. Fulfilling risk management combined two methods, we can reduce project's budget, term and resource's usage, and prevent risk with the optimum measures obtained by the exact risk analysis.

Requirement management is an important phase that has a significant influence on the project success. As a risk to a project fail is getting bigger, people adopt Systems Engineering method to the development of the effective requirement management. Accordingly, Railroad Safety Technology R&D Corps. is progressing the plan of the construction of Railway Safety Test Facilities as a part of the Railway Total Safety Project to enhance the railway safety, and carrying out researches on effective requirement management methods with Systems Engineering techniques. To support that, we introduce the Systems Engineering Requirement Management Process and propose the more effectual management method of constructing the Railway Safety Test Facilities applying the model-based systems engineering tool to the research.

This paper explains that tacit knowledge is a critical component for the success of government-led R&D project selection, where rapid and accurate decision making need to be made under lack of information circumstances. It also explores ways to fully exploit the tacit knowledge of experts participating in the Korean government's R&D project selection process. Some of these include: (1) strategic attention from the top officials, (2) forming self-organizing teams, (3) establishing a horizontal and risk-taking culture, (4) encouraging a sense of responsibility in creating and sharing tacit knowledge, and (5) providing a seamless monitoring system and training.

민간 개발 프로젝트의 초기 기획단계는 프로젝트 전체의 성패를 좌우하는 중요한 부분이다. 하지만 기존의 기획단계 분석결과의 신뢰도는 중요도에 비해 높지가 않다. 따라서 기존 민간 개발 프로젝트 기획단계의 사례연구 및 연구자료 분석을 통해 근원적인 문제점을 분석하였다. 그 결과 기획단계의 업무 절차나 방법에 관한 체계적 분석 모델의 구축이 되지 않은 것에 그 원인이 있는 것으로 나타났다. 이에 본 연구에서는 그 해결방법으로 기획단계 분석절차 모델과 리스크 관리 모델 구축을 통해 체계적 분석방법을 제시하고자 한다. 제시된 분석방법은 기획단계 분석결과의 신뢰성을 증대시킬 수 있을 것으로 기대된다. 이와 함께 프로젝트 진행단계별 가이드라인을 제시함으로써, 프로젝트의 효율적 수행을 지원할 것으로 기대된다.
