Entropy Weight and TOPSIS Based Bid Evaluation Model of Construction Applied Research

Engineering project evaluation is essentially in multiple targets,much more than choosing rules for evaluating the decision making problems.It is the owners’ choices to determine some appropriate contractors and ensure that the key to finish the work.According to the existing engineering project evaluation methods brings malicious competition,evaluation factors and weights are difficult to be reasonable definition and defect,the article puts forward in using entropy principle and the ideal solution by combining the thought construction bid assessment.This article analyzes the existing evaluation methods and its shortcomings,and then based on the evaluation of the characteristics and the influence factors of the system to build bidding factor set.And then based on entropy weight method,it is to determine the objective principle of the index of evaluation factors,to avoid the many factors determining weight of subjectivity,and according to the ideal solution to evaluation objects for sorting,determined the optimal scheme,finally,through the construction of the construction of the project bid assessment that the examples of the application of this method.
