Research On The Decision Model Of Automobile Conceptual Design Based On The Theory Of Data Mining

Automobile conceptual design is a complex decision full of innovation, multi-solution approximation, experience, integration, which is a crucial phrase in automobile design. Research on the decision model of automobile conceptual design based on the theory of data mining effectively embedded data mining, artificial intelligence and the product conceptual design theory and technology, which is a necessary means to provide decision support for conceptual design and also is an urgent problem to be resolved in mechanical and automobile industry of China. This study first analyzes today's challenges and problems that automobile manufacturers are facing, and the problems encountered in the automotive design process. Illustrating the purpose and meaning of automobile conceptual design. Second, it analyzes the related fields' concepts, including contents and methods design features of automobile conceptual design and knowledge of data mining theory etc; Finally, establishing the decision-making model of automobile design. Achieving the solution decision-making model through data mining and decision tree algorithmsIn this study, automobile conceptual design is taken as a combined research field and the method of QUNIT model in this domain is studied on. Being armed at the characters of variant design for complex automobile conceptual design, Establishing automobile design model,using data mining methods and decision tree algorithm to solve this problem,establishing model and solution algorithm for decision-making model of automobile design established by this study,the program results and successful automobile models in the database is insignificant,it shows the higher accuracy of the algorithm.and the matching performance is better.This paper makes a deep study in automobile conceptual design based on decision tree algorithm.Finally getting a good clustering result and gaining the knowledge rules through the decision tree clustering algorithm.These proved the successful in automobile conceptual design based on cluster analysis method--decision treeThis study realizes the system development of decision support system to support decision-making program and provides our customers'customization convenient and efficient design based on the overall framework of automobile design.
