The Optimization Method Based On Uncertainty Theory for Complex Systems

At first, for the complex systems optimization methods, in this paper, three kinds of optimization problems of the complex systems focus on three stages of complex systems are discussed; Secondly, the relations between systems structure, systems capacity and systems effectiveness is disputed , and the optimization models based on effectiveness for complex systems optimization is built, and on the basis of uncertainty theory applied in quantifying qualitative information , the method applied in systems capacity evaluation is set up, and the algorithm with rough set, based on systems effectiveness simulation, for systems capacity weight is built; At last, the algorithm for the optimizatiun model is put forward. The optimization approach is a new method for complex systems optimization.
