【摘要】 随着社会经济的飞速发展,企业面临着产品结构更加复杂及生命周期缩短的矛盾。制造业企业为在这种市场趋势中快速地生产出低成本及个性化的客户满意产品,提高市场竞争力,正从大规模生产转向大规模定制生产。而利用先进产品建模技术和产品数据管理技术构建产品变型设计系统可以使企业加强产品的数据管理,实现敏捷设计与制造,从而进一步实现这个目标。本文采用理论研究与应用相结合的方法,在分析大规模定制生产产品变型设计技术研究现状的基础上,对汽车产品实施变型设计的方法及产品管理技术进行了理论研究,提出了一种面向大规模定制的、基于企业PDM系统的产品变型设计系统。本文建立的变型设计系统采用参数化建模的方法,建立了汽车产品的产品族模型,并与企业的PDM系统集成,按照模块化后的产品族模型在PDM系统中建立汽车产品变型设计的实例库,解决了大规模定制过程中产品数据复杂的难题,在实例库的基础上,通过建立专家系统,应用基于实例推理的变型设计技术,实现汽车产品的变型设计,使产品的变型设计具有智能化的特点。本系统面向客户的个性化需求,针对汽车生产当中设计人员的实际工作情况,具有可扩展性、集成性和可视化的特点,为设计人员提供了友好的人机交互界面,操作简单,能够使设计人员快速地检索出设计实例,从而能够以最短的时间设计出客户定制的个性化产品,来满足不同的客户需求,为企业节约了成本,提高了产品设计效率,缩短了开发周期,对企业进一步实现大规模定制有现实的意义。更多还原

【Abstract】 With the rapid development of social economy, enterprises are faced with the contradiction between more complex product structure and reduction of product lifecycle. Manufacturing industry is transferring from mass production to mass customization (MC) production for helping enterprises to make low cost and individualized product to satisfy customers and to enhance their competitiveness. Moreover, using advanced product modeling technology and product data management (PDM) technology to build product variant design system can further achieve this purpose by enhancing the contact between enterprises and customers and managing product data effectively. Therefore, based on the actuality analysis of MC production and product variant design, this paper adopts method that combines theory research and practice to study the product variant design way and then a product variant design system for customization based on enterprises’PDM system is proposed.Parameter modeling method is adopted to build automobile product family model in this variant design system. Integrating with enterprises’PDM system and stored the product family model in PDM system, the automobile variant design case base is built, which solved the problem of the complexity of product data. Based on case base, through building expert system and applying case-based reasoning variant design technology, automobile product variant design is achieved, which makes the system have the character of intelligence.Facing to individualization of customers and designer’s working condition in automobile product design, the system provides friendly man-machine interaction interface which is easy to handle and can help designers conduct product variant design easily. It has the characteristics of expansibility, dispersivity, integrated ability and visibility. Through this system, production cost is saved, design efficiency is increased and the product design cycle is shortened, therefore it has the practical significances for enterprises to achieve mass customization strategy.更多还原
