Abstract: Disadvantages of the present research in design structure matrix optimization algorithms were analyzed. Based on the numerical design structure matrix and the genetic algorithm, a new optimization algorithm of design structure matrix was brought forward. Compared with the old algorithm, the new algorithm improved optimization objective, object function, evolutionary method and optimization result. With the new algorithm, not only best solution could be found rapidly so as to realize optimization of the design process, but also the design time and cost could be minimized. Result of an example revealed that the new algorithm decreased the design difficulty and cost effectively.
