基于超可加测度的融合设计建模及其不确定推理方法研究

Currently, the design method with Model-driven for complex products is complicated. Also, little knowledge is embedded into design model, so that it is difficult to support intelligent design. Besides, reasoning mechanism with match-mapping is inapplicable for the complex design. For these problems, some key relevant science and technology issues need to be overcome. Those issues include the design modeling of knowledge-embedded, automation and intelligence in modeling process, and uncertain reasoning of the knowledge model for fusion design. To solve these issues, technology route of fusion design modeling based on excessive additive measure and its uncertain reasoning is proposed, fragmentation modeling approach based on dynamic and static knowledge element is studied, similarity model built for the fragmentation design model with detecting the same structure figure is established, fusion modeling method of fragmentation model with super additive measure is researched, and uncertain reasoning method used in fusion design model with incomplete information is studied. In the requirement of fuzzy design, various design decisions are obtained under a certain reliability. Fusion design modeling and its simulation system with uncertain reasoning are researched. And, this system is validated through practical applications. To improve intelligent design level of complex products, the model-driven design method is applied to practical engineering, which builds a theoretical and technical foundation for efficient engineering applications.
