摘要： 产品数据对象分布问题一直是分布式产品数据管理（DPDM）研究的热点。基于当前硬件条件的限制和信息的海量性，把合适的产品数据对象分布于合适的位置成为决定一个分布式产品数据管理系统性能的很重要因素。因此，该文以国内某通信公司的实际应用为背景进行了产品数据对象分布分析，提出了一个综合目标驱动的产品数据对象分布模型，所提出的产品数据模型通用性强，便于推广应用。

Abstract: Distributing problem of product data objects is always the research focus for the distributed product data management system(DPDMS). Based on the limits of hardware conditions and massive information, it is a critical factor evaluating the performance of a DPDMS how to allocate product data objects to the right locations. Therefore, a multi-objective driven distributing model of product data objects is proposed by analyzing product data of an intranational communication incorporation. The distributing model of product data objects has better adaptability, and it may be popularized easily.
