A Method of Fuzzy Decision for Engineering Appraisal Bidding

To make a more scientific appraisal for the units and to provide a scientific basis for final results, considering it is easy to realize to take single factor evaluation for bidding units,bidding method of evaluating bidding units based on single factor evaluation is built by introducing multicriterion fuzzy decision theory in this paper. According to type of practical project and requirement of owner, evaluation variables can be adjusted at any moment. The proposed model showed better effects than the existing model.
