多元特性驱动的产品族柔性化设计方法研究

Product family multiple characteristics include the dynamic uncertainty, multiscale correlation, multi-parameter coupling. According to the fact that product family design method rarely analyzes multiple characteristics generation mechanism, adapts dynamic demand changes and improves internal flexibility between product modules and design parameters. This project proposed a multiple characteristics driven product family flexible design method. The method has great significance for improving the flexibility of product family design to reveal the generation mechanism and multi-domain transmission mode of product family multi-characteristics. It also illustrates the decoupled fusion mechanism of coupling parameters. Firstly this project is to research product family dynamic uncertain demand analysis and forecasting techniques, aims to improve the dynamic response ability of the product family to the change of the market demand in the future. Then with the research on multi-scale coupling product family flexible module identification technology, the method can solve cross-scale and multi-scale coupling problems of product family flexible modules. Decoupling and fusion problem between product family structure variables and design variables can be solved, in accordance with the research on flexible configuration design method for decoupling and fusion of coupling parameters.Improving flexibility of product family configuration design is a target for the method. Finally a product family flexible design prototype system is developed, and the application verification for flexible design of forging press product family is carried out.
