摘要
为了定义和表达产品在各个生命周期阶段的数据并且建立及维护数据之间的联系, 将产品全生命周期划分为五个阶段:需求分析、概念设计、工程设计、加工制造、服务支持.按照所划分的阶段,提出了将存储于分布式数据库中的所有相关产品数据和文档通过逻辑映射成产品需求模型、概念模型、工程设计模型、制造模型和服务支持模型的产品全生命周期模型体系框架.在此基础上重点构建了产品制造阶段的模型,包括零件工艺信息模型、产品装配信息模型和企业工艺资源模型.
To define and express the data of each and every stage in the product lifecycle and maintain the interdependencies among the data, the product lifecycle is divided into five stages, i. e. , demand analysis, conceptual design, engineering design,manufacturing and service/support. Then, a framework is proposed for the lifecycle model through logical mapping, which is set up taking advantage of all the data and documents relevant to the product and stored in decentralized databases to cover the five submodels corresponding to the five stages. Based on the framework, a manufacturing information model is developed for the product, including the information on parts＇ processing, assembly and manufacturer＇s technology resource.
