Abstract: In order to choose the optimal bid scheme in the coal mine construction project, this paper establishes evaluation indexes and applies entropy weight to computer the entropy and entropy weight of the evaluation indexes, then sorts bid scheme on basis of the distance and closeness of the ideal point and select the optimal bid scheme. The results show that this method solves the drawbacks that the evaluation indexes depend on the subjective assumptions too much and provide an effective method for choosing the optimal bid scheme of the coal mine construction.
