The essence of select multidisciplinary design technique optimization is a multiple objective synthetic evaluation problem.In this paper,considering the number of design variables and constraints,the calculation accuracy and com- plexity and the global convergence,a MDO technique fuzzy synthetic evaluation model is constructed.Using the number of Euclid distance with weight as an evaluation criterion,a practical example,the select of Improved Sequential Quad- ratic Programming(NLPQL).Adapted Simulated Annealing(ASA).Multi—island Genetic Algorithm(MIGA)and Sequential Quadratic Programming(DONLP)in the multidisciplinary design optimization of turbine blades is given. The result shows the efficiency of this method.
