虚拟产品设计方案神经网络决策模型研究

虚拟原型逼真设计作为虚拟产品开发研究的一个方面,是近几年发展起来的新技术,主要研究虚拟环境下的产品建模问题以及基于仿真的集成产品和过程设计问题。生命周期虚拟产品设计方案评价模型是虚拟原型逼真设计模型实现的重要模块之一,论文在设计方案多目标多级模糊综合决策模型的基础上,研究并建立了设计方案ANN多目标决策模型,该模型已应用于仪表新产品开发决策支持系统中。

Research on the ANN Decision Model of the Virtual Product Design Project

Virtual Prototype Reality Design(VPRD),as one aspect of research on virtual product development,is a new technique that developed recently.Main research is problem of product modeling,integration product and process design based on simulation under virtual environment.The project evaluation models and decision methods based on Product Life-Cycle is one of important modules which consist of the framework of VRPD.In this paper,based on the mathematical model of multi-objective and multi-layer fuzzy comprehensive evaluation,the ANN multi-objective decision model of the design project is built.This model is applied to a Decision Support System(DSS) for the new product deve-lopment of instruments.
