Study On Construction Project Evaluation Model Based On Entropy Theory Of Matter-element Extension Theory

Project bidding tender units is an important way for project selection characteristic of the project's contractor. The project evaluation process is the most important part of the evaluation quality directly determines the quality of projects.Therefore, in order to ensure that the project evaluation aspects of fair, impartial,scientific, reasonable and protect the interests of both the bidding and improve the quality of construction projects, research scientific, reasonable and effective evaluation theory has great significance.Based on the characteristics of the construction projects in the research status review, and an overview of the general principles of the program and the evaluation of project bidding, analyzing disadvantages of traditional evaluation methods, based on the proposed Entropy and Matter- Element Extension comprehensive evaluation methods theory and examples of verification.Firstly, the theory of engineering construction project bidding to start, the status quo through the detailed study of the bidding fine analysis of domestic and foreign construction projects evaluation and clarify the approximate direction of domestic and foreign research evaluation theory. This article also describes in detail some of the theories of bidding, a number of shortcomings and problems such as the scope of the tender, the way, the basic program and the evaluation process currently exists, through a combination of project evaluation is to analyze the actual situation, the system I have pros and cons of existing evaluation theory for the development of future evaluation theory provide some basis. The article also project evaluation index system conducted in-depth research, project evaluation index system was constructed.On this basis, the proposed combination of information entropy theory, entropy matter-element theory of matter- element extension extension theory, for the evaluation of the Project. In the fourth part of the article, first introduced the two basic theories Entropy and Matter- element theory, through the information entropy theory analysis, the expert scoring method for the data base to the basic principle of information entropy theory to determine the evaluation index weight method; analyte element by extension theory, sort out the specific ideas the extension theory is applied to the evaluation of the project. Secondly, Entropy and Matter- element basic principles of the theory of law evaluator, features, judged to be the main principles and steps carried out a detailed analysis. First advantage of using entropy fuzzy theory and quantitative indicators index system project for processing qualitative data and determine the weight of heavy Evaluation Indicators based on information entropy theory and fuzzy comprehensive evaluation. The introduction of the theory of matter-element extension assessment method, the establishment of the classical field matter element evaluation, and correlation matrix section domain, and then re-index weights determined above according to the principle of the maximum correlation degree, acquisition element evaluation results. Thus we build construction project Entropy and Matter- element theory integrated evaluation. Through the example analysis, application of this model allows evaluation of construction projects over the process more scientific and accurate.After analysis, the proposed construction project engineering Entropy and Matter- Element Extension comprehensive evaluation of the theoretical model has a certain practicality to provide a theoretical basis for more effective evaluation of the Project.
