Abstract: In order to make the comprehensive decision-making results more consistent with the actual situation, a fuzzy comprehensive decision-making model with fuzzy combined weighting is developed in this paper. The fuzzy combined weighting method (FCWM) is proposed in the model to determine the weights of decision factors (indexes). The subjective weight and objective weight are combined in the FCWM to reduce the decision error caused by either using subjective weight or objective weight alone. In addition, the fuzziness of combined weights is taken into account in FCWM to make the decision-making results more realistic. The fuzzy structured element is used to express fuzzy numbers in the model. The analysis algorithm of fuzzy comprehensive decision based on the expression of fuzzy structured element is given to solve the problem of complex operations among fuzzy numbers. The decision model was applied to the order of metal mine gob management. It provides guidance for gob management reasonably and orderly. The research results also provide a new idea for the determination of weights in other fuzzy analysis models.
