| Abstract: | Aiming at fuzzy uncertainty of design features and requirements in the conceptual design stage of products, a design method of complex nonlinear systems based on ideal degree and rough number multi-attribute decision was proposed. The set of target technical systems and the set of super systems were determined, and the subsystem was solved at the ideal level. A functional structure model and the product design characteristics hierarchy diagram were established. Based on rough number, the weight factor was calculated. Then the relative evaluation results of design requirements were calculated, and complexity of the target subsystems was analyzed. The system complexity was eliminated by using TRIZ . The feasibility and effectiveness of the proposed method were verified by an example of lower extremity exoskeleton engineering. |
