摘要在复杂产品设计中，产品设计知识起着决定性的作用。而产品设计知识都是依附于产品设计过程而存在的，因此如何清晰而又准确地定义产品设计过程成为了产品设计的关键所在。

目前，智能设计要求设计系统能够有效地为设计过程提供知识服务，而现有的知识本体无法满足产品智能设计的要求，有关本体的研究局限于设计知识的表示、获取和重用上。过程本体描述了一系列设计活动与相关知识的相互关系，进行设计过程本体的构建并实现其与知识本体的映射是目前实现产品智能设计的有效方法。65183

本文提出了过程本体构建的流程和方法，并以身管为例进行了身管的需求分析以及需求建模，构建了身管设计过程本体；进行了以过程本体为基础的智能设计系统的构建，主要进行其核心功能模块——本体映射的相关算法的分析和程序实现。

总之，本文将过程本体和本体映射理论应用于实践，有利于产品设计走向更加智能化的方向，提高产品设计的工作效率和工作质量。

Title  The Research  of Ontology Mapping In Intelligent Product Design                    

Abstract

In complex product design, product design knowledge plays a decisive role. The product design knowledge is dependent on the existence of the product design process, so how clear and precise definition of the product design process has become the key to product design.

At present, intelligent design requirements and design systems to effectively provide knowledge services for the design process, and the existing body of knowledge products can not meet the requirements of intelligent design, limited research on ontology design knowledge representation, acquisition and reusability. Design process ontology describes a series of activities associated with the relationship between knowledge, design process and achieve its ontology and ontology mapping is the product of intelligent design to achieve an effective way.

This paper presents the process of ontology construction processes and methods, and an example to the barrel barrel needs analysis and requirements modeling, design process to build a barrel body; carried out in order to process ontology-based intelligent design system construction , mainly for its core function module - ontology mapping and analysis of algorithms related to program implementation.

In short, this article will process ontology and ontology mapping theory into practice is conducive to product design toward a more intelligent direction, improve product design efficiency and quality of the work.
