摘要
产品全寿命动态信息模型是产品全寿命动态模型的最重要部分之一 ,它是创建信息系统并进行全寿命管理的基础。本文叙述了产品全寿命动态信息建模涉及的信息分类、各类信息项之间的关系、数学表达式、信息编码及动态综合描述等。以船用低速柴油机为对象 ,分析了其全寿命的信息流和信息系统框架并应用本动态信息建模方法和现有的全寿命管理 (PL M)方案阐述了实施步骤。
The PLDIM (Product Lifecycle Dynamic Information Model) is the most important part of PLDM (Product Lifecycle Dynamic Model) and it is the basis for creating the information system and implementing PLM (Product Lifecycle Management). The information classification, the relationships among all information items, PLDIM mathematic expression, information coding and the 3D synthetic description of the PLDIM are presented. The information flow and information system structure based on the two information centers and Internet/Intranet are proposed, and how to implement this system for ship diesel engines is also introduced according to the PLDIM and PLM solutions.
