支持方案设计和技术设计的产品模型研究

基于表达设计意图和支持产品设计全过程的思想,分析方案设计和技术设计过程及产品信息的形成过程,提出支持产品方案设计和技术设计的产品模型。给出了产品组成结构、装配关系和结构设计3类产品信息的模型,其中结构设计信息包括装配特征、工艺特征和结构特征。列举并分析实现装配关系的装配特征实例,研究装配关系与装配特征间的功构映射,提出依据工程实际建立装配关系与装配特征间的稳定映射,实现产品设计知识的显示表达。最后用实例说明产品信息的传递和生成过程,验证该模型的有效性。

制锁业BOM的实现

产品组成结构(BOM)的设计是生产管理软件MRP/MRPII-ERP系统的核心,是运行MRP三个基本输入信息之一。根据产品的特性进行不同的构造,可以减少基础数据准备实施工作量,提高物料分解算法的速度,提高生产管理系统的效率。

Practice of Project Management Methodology for Commercial Aero engines Based on Integrative Project Architectures

To collect and share information of projects or products and make it consistent and correct so that the quality and costs of projects can be effectively controlled,an integrative project architecture integrating different types of breakdown structures is necessary.In this paper,the international research status on work breakdown structure(WBS)was analyzed,and an integrative project architecture for commercial aero-engines was designed,where product breakdown structure(PBS),WBS,organization breakdown structure(OBS)and cost breakdown structure(CBS)were integrated and built.And the architecture was applied in information systems.A transfer from technological views of complex products through their lifecycles to management views has been realized with this standardized architecture,thus development tasks and costs can be controlled.
