支持设计决策的材料信息模型

Material Information Model Supporting Design Decision

材料信息是支持并行设计决策信息的重要组成部分。本文在深入分析了产品与工艺设计决策需求的材料信息基础上,建立设计决策支持的材料信息需求框架;并在此基础上,提出基于XML的材料信息三层表示模型,即基础层、逻辑层和应用层;最后,从应用层上,建立基于IDEF0的设计决策支持的制造质量信息功能模型。

Material information(MI) is very useful for supporting design decision-making.In deep analysis of the product and process design decision-making needs of material information,material information requirement framework for supporting design decision is built,and on this basis,the XML-based representation of three layers of MI model is proposed,that is,the underlying layer,logical layer,and application layer.Finally,from the application layer,decision-supported manufacturing quality information feature model is built based on IDEF0.
