Multidisciplinary mixed collaborative design optimization

The relationship of the hierarchic system,the non-hierarchic system and their subsystems was studied in multidisciplinary design optimization(MDO).The mixed system was divided into four structures.A method of multidisciplinary mixed collaborative design optimization(MMCDO) was made by establishing the collaborative rules of variables and objective functions.An application of the MMCDO method to optimal design of a micro-machined gyroscope shows satisfactory results.
