This paper will establish a comprehensive coordination model with the cost, quality and time limit for project, taking quality objective into consideration, using multi-attribute utility function theory and guiding by the highest benefit which is creative of the three objective of project. Besides, it will achieve objective weight as far as possible of every goal with AHM, which will respond to the...
In a complex decision system, it is unavoidable to deal with the fuzziness of people's thinking, judgment and uncertainness of the information. This paper considers the uncertainness and fuzziness in the complex decision systems, and discusses the problem about extracting the fuzzy weights of the projects from the fuzzy judgment matrix. A new method is developed for ranking fuzzy priorities from fuzzy...

This paper analyzes problems of low efficient information negotiation in MTR construction among different participants. An automation negotiation system scheme based on Web is proposed. Also, concession strategies and negotiation utility assessment mechanism are built to make sure all the participants in construction can auto-negotiate with each other through the system. Its maneuverability is validated...
Multiple criteria decision modeling is proposed for determining the most preferred bidding markup in a competitive bidding situation. This paper presents a new evaluation approach - VIKOR method - to solve the MCDM (multiple criteria decision making) problems with conflicting criteria or criteria of different units. Since this method provides a maximum "group utility" of the "majority"...
The post evaluation of construction projects is an important link of the whole project management. The indexes of post evaluation usually include preference information. In the paper, dominance-based rough set and grey relational analysis (GRA) are combined to apply to the process evaluation in the post evaluation of construction projects, and a formal and effective method of post evaluation is proposed...
