究和实践，总结多年的应用成果，以航空制造业为背景，提出制造业数字化的总体框架，给制造业数字化应用平台的建设提供参考。
二、航空制造业数字化总体框架研究
（一）总体框架设计要求
面对竞争激烈的市场大环境，制造业的唯一出路是在最短的时间内以最有效的方式生产出最能满足客户需要的产品。制造业企业间既有竞争又有联合，只有发挥各自的技术和资源优势，才能降低成本，分摊风险，共享市场。构建数字化工程体系是达到以上目的最有效的方法和手段。
数字化工程体系的核心是信息共享和过程管理，因此，制造业数字化工程的总体框架必须能实现制造业企业内部和企业间的信息共享和过程控制。
产品数据信息和产品生命周期相关的其他信息在各企业、各部门、各专业之间的顺畅流转，是产
