Comprehensive evaluation of mine design tender scheme

Evaluating tender is a painstaking and key part of public bidding. There are many index factors, which influence design tender scheme, but that every factor reflects the design tender scheme well or bad degree is disagree each other. It is very important to comprehensive evaluation for the tender scheme. In the paper, mine design tender schemes are analyzed, and hierarchy structure model of mine design tender scheme is set up. On the basis of practical example, the powers of all the factors are calculated with the aid of analytical hierarchy process, and the best mine design tender is obtained by means of fuzzy evaluation and gray system correlation analysis theory. A beneficial reference is provided for improvement of the method of the evaluating tender, and the decisionmakers can not only avoid subjectivity, but also strengthen objectivity.
