The purpose of this study is to construct a value-oriented sizing and cost estimation model for system integration projects. In particular, this study is to build a system architecture design and integration cost model, and a network design and implementation cost model. Unlike software development projects, system integration projects include knowledge-intensive professional services on system architecture and network design areas. Because of these work's high invisibility, the cost of these services is hard to estimate and measure. Therefore, we need to develop value-oriented cost models. This study presents 6 value-oriented cost models, and tests statistical significance of these models with real system integration project data. The results show that cost factors on these models are valid, and models are statistically significant. Future work is needed to integrate various cost models and apply the whole model to field projects to increase model's prediction accuracy.

It is the urgent task of induce the inhabitants to utilize the public transportation instead of the personal transportation to dissolve the traffic jam. But construction of the subway, the representative substitute means, demands a great of investment expense including various kinds of expenses. So the technical development and research of standardization of FRT(Fuel cell Rubber tired Train), the eco-friendly public transportation system low in construction expenses, effective, excellent in approach as well as in traffic, are propelled positively. This project wants to propose exterior design FRT in which original creative methods are utilized with the target of development and construction of FRT which coincide with anthropocentric eco-friendly traffic system. Utilizing the proposed style as the basic materials, this project wants to grasp difficulties, and to establish the way to solve and develop them.

The Burj Dubai Project will be the tallest structure ever built by man; when completed the tower will be more than 700 meter tall and more than 160 floors. The early integration of aerodynamic shaping and wind engineering considerations played a major role in the architectural massing and design of this residential tower, where mitigating and taming the dynamic wind effects was one of the most important design criteria. This paper presents a brief overview of the structural system development and considerations of the tower and discusses the construction planning of the key structural components of the tower.

This paper presents results from a computer-aided systems engineering application to system development projects. RDD-100 version of ALC Inc. was used in this work. The framework adopted in the study takes a unified approach to the system design and the process management associated with it, thereby coherent and full traceability between them is maintained. Conventional system engineering process supported by the tool is adopted in the system design. On the other hand, the same tool is also used to the systems engineering management to get full traceability between system design data and engineering management data. It is greatly helpful in managing many sub-contractors in the sense that the traceability can help identify the sub-project responsibility as well as the objectives of the project in coordination with interface requirements. We conclude with the advantage and limits of our unified approach.

The communication between members who participate in the product development project has an effect on the project time, cost, and quality. This reason requires the engineering database which is the kernel of product information. This study focuses on data and process modeling for engineering database related to electronic consumer product. First, Through the definition of engineering database, the characteristics of engineering data, mainly product data are analyzed. Second, The object and class for engineering database are defined. This results of the study can be applied with engineering database design and workflow design of PDM. It also can be used as a reference model when the company develops product with suppliers.

Garak Market Modernization Project Phase 1, which is the public projects worth 1,75 billion won, was delivered by adopting modifiable bid of BOQ on the lowest price award system. The modifiable bid of BOQ system allows bidders to modify quantities based on their own drawings and construction specifications and requirements. It was initiated by the government for minimizing design error and for inducing technical competition between tenders by checking errors. At that time the bidding, it allowed modifying the BOQ all the works. In the construction phase, the responsibility for the design changes, due to mistakes and omissions on design documents and BOQ were disputed between the owner and the contractors. This study analyzed the problem of the system and addressed a need of improvement.

This study compared and analyzed middle and high school's homebase and media space which are installed along with the introduction of subject classroom system operation method, with regard to the position of arrangement, the type of arrangement, and the change of area, etc. which were changed and applied per the phase of project. For this, design competitions were implemented since 2006 targeting the cases which participated in design directly-indirectly in the researcher's architectural firm, present construction documents among the selected BTL(Build-Transfer-Lease) were completed, and the examples of 10 schools(design competitions 2 schools, BTL selected plans 8 schools) were analyzed, which were operating variation type.

본 논문에서는 분기형 관수로 설계방법의 모델을 제시하기 위하여 선형계획법(LP)을 도입한 설계를 연구하였다. 실제 사업지구인 전남해남군 간척사업지구의 자료를 토대로 LP 수식화에 필요한 자료를 수집하여 파이프 관경과 펌프마력설계를 최적화하였다. 연구결과 기존의 관망설계와 비교해 보았을 때 파이프 관경과 펌프마력등에서 더 경제적인 결과를 얻을 수 있었고, 수리모의모형을 사용한 기존의 설계방법보다 객관적이고 효율적인 설계가 가능했다. 이러한 결과를 바탕으로 본 논문에서 연구된 선형계획법을 이용한 분기형 관망설게의 모형이 실무에서도 효율적으로 적용될 수 있음을 알 수 있었다.

The Purpose of this paper is to describe a decision model which can be used to establish an implementation system of renovation for university building. Any implementation model relies on the work scopes of renovation which varies design, project cost, construction duration. The renovation system is subject to evaluation of work steps which is different from each project. Accordingly, the decision model of renovation is necessary to use the application of the analytical hierarchy process. Many of the performance steps used in general renovation condition may be known with uncertainty. This research has shown how probabilities can be explicitly incorporated in the decision model of renovation to assess this uncertainty.

In 2004, a department of engineering education was established at Virginia Tech and Purdue university in the United States. Innovation of engineering education for improving the quality of engineering college education has been progressing. Content of subject of engineering exploration was developed newly for engineering college freshmen. And, effect of a sustainable energy design project on academic achievement for engineering freshmen at Virginia Tech in 2006 was researched. The project was performed throughout a 6 weeks period with one by 50 minutes lecture by professor and one 90 minutes workshop by TAs (Teaching Assistants) every week. To analyze the data, statistical package SPSS (ver. 15.0) was used. In responses to an open-ended question about freshmen students' perceptions of their improvement in design skills, the 3 most identified skills were teamwork, design process, knowledge. In, Korea, an innovation relating to engineering curriculum, facility, instructional strategy and so on will be required.
