본 연구에서는 공사기획단계와 시공단계에서 공사의 성공적 이행을 보장하기 위해 기존의 리스크관리 프로세스를 살펴보고 이에 적합한 새로운 리스크분석 모델인 CRMS를 제시한다. CRMS는 시공자가 건설공사의 이행중 리스크를 확인하고, 분석하고, 관리해 가기 위한 리스크관리절차이다. 이것은 시공자가 인지한 리스크를 정량화하고 이에 적절한 리스크관리 방안을 수립하는데 큰 도움을 줄 수 있다. 특히 건설공사의 리스크관리 중 가장 중요하고 어려운 부문이 리스크를 인지하는 것으로 볼 수 있다. 따라서 본 연구에서는 건설공사의 리스크인지를 쉽게 할 수 있는 절차의 개발에 좀 더 집중하였다. 리스크의 확인은 프로젝트의 외적 리스크와 내적 리스크로 구분한다. 글로벌 리스크의 경우 확인을 용이하게 하기 위해 분석에 필요한 목록을 제시하고, 아울러 RBS의 구축방법과 WBS와의 연계방안을 제시하였다. 이러한 연구결과는 리스크관리용 전산시스템을 개발하기 위한 기초자료로 활용되게 될 것이다.

We suggest a distributed framework for task assignment in the computer-controlled shop floor where each of the resource agents and part agents acts like an independent profit maker. The job allocation problem is formulated as a linear programming problem. The LP formulation is analyzed to provide a rationale for the distributed task assignment procedure. We suggest an auction based negotiation procedure including a price-based bid construction and a price revising mechanism. The performance of the suggested procedure is compared with those of an LP formulation and conventional dispatching procedures by simulation experiments.

We consider a postal transportation planning in the transportation network of the form of hub and spoke. Given mail sorting centers and an exchange center, available vehicles and amount of mails to be transported between mail sorting centers, postal transportation planning is to make a transportation plan without violating various restrictions. The objective is to minimize the total transportation cost. To solve the problem, a tabu search algorithm is Proposed. The algorithm is composed of a route construction procedure and a route improvement procedure to improve a solution obtained by the route construction procedure using a tabu search. Computational results show that the proposed algorithm can solve practically sized problems within a reasonable time and the quality of the solution is acceptable.

The governmental attitude toward private investment and financing for infrastructure projects has changed from the initial prohibition to the current encouragement in China, which has been embodied in the legal documents and administrative process. However, the problem of identification, bidding, and approval procedure for privately financed infrastructure projects has been observed in policies and administrative measures promulgated by different or even the same government branches, which is prohibitive factors for smooth project implementation. After analysis of the identification, bidding, and approval process of infrastructure projects, the authors proposed a simplified and alternative procedure and clarified the key points of relevant project documents.

In this study we examine Taiwan's overall performance in accordance with sustainable construction by developing an appraisal indicator framework. The framework consists of five layers, from bottom to top: the indicator; the indicator category; the core cluster; the theme; and the overall performance. The procedure for the development of a sustainable construction indicator system is outlined. Finally, a framework consists of 3 themes, 10 core clusters, and 33 indicator categories are established. Following the established framework, 67 proper indicators are selected for each category in the framework, and data of the 53 indicators are collected respectively from a nation's statistical databank in Taiwan. Sustainable construction index aggregated step-by-step from the indicators, the indicator categories, the core clusters and the themes is computed to assess Taiwan's progress in sustainable construction. The preliminary results and the discussion are reported.

The building construction projects include a variety of risk factors due to uncertainties. To succeed in the projects, it is important how risks are managed. Risk management is composed of identification, analysis and response. Especially, the risk analysis is important to objectively calculate significance of risk factors. This paper evaluates a method to find priorities of risks using the AHP(Analytic Hierarchy Process). The method has some defects; (1) the consistency becomes weak as the number of pair-wise compared risks is large, and (2) the input and output procedures are complex when risks are added to or removed from a risk database. Thus the paper adopt the PROMETHEE(Preference Ranking Organization METHod Enrichment Evaluations) analysis process which is able to overcome the limitation of the AHP restricted to 9 risk factors. The PROMETHEE method makes the procedure of risk analysis simple, when the risk factors pull out and put in the risk database. The purpose of this study is to prove the possibility of the PROMETHEE analysis process by being compared with AHP.

This study aims to propose an assessment model on environmental economics which will provide useful information in making a decision for the implementation of pro-environmental and economical construction projects. To meet the objective, this study suggests a procedure to estimate environmental cost of construction projects. The model combines environmental load assessment and environmental value assessment. The environmental cost of pollutant generated from the construction project was estimated utilizing the Contingent Valuation Method (CVM) which is a value assessment method borrowed from economic science. The devised model is expected to provide a useful methodology that will scientifically support the planning and management of sustainable construction not only in the environmental aspect but also in the economical aspect.

A city development has been focused on solving a housing shortage of city resulted from rapid industrialization and population increase in city. However, such a development has caused many problems in environment, economy, safety, and so on. In recent, therefore, a new paradigm of a city development is required, and thus ubiquitous city (U-City) concept appears. U-City development, which combines construction method and IT technique, creates a new composite space, and help people improve quality of life in terms of solving many problems caused by existing method of a city development. However, there is no guide to build U-City up to date, and most present U-City projects have processed following past method of city development. Therefore, an objective of this paper is to suggest an explicit procedure of enforcement design in U-City system.
