Considering uncertain factors in multi-objective flood operation,some risk indexes in flood control operation were extracted,the interval number based multi-attribute decision making with fuzzy trade-off method was proposed to solve the optimum seeking problem in archive set,and multi-attribute decision matrix was established to avoid the vagueness and uncertainty of candidate schemes.Considering possibility degree matrix with subjective weights,positive ideal scheme and negative ideal scheme were selected from candidate schemes. These candidate schemes were sorted by the difference degree and closeness degree of ideal schemes,and finally the satisfactory multi-attribute decision scheme was obtained by the proposed interval number based multi-attribute decision making with fuzzy trade-off method.
