基于知识的大规模定制产品可拓配置设计

针对现有产品配置设计方法中对客户性能需求研究的不足,提出了基于知识的大规模定制产品可拓配置设计理论与方法.通过分析产品设计过程中的信息处理,明确了基于知识的设计系统开发思路,应用物元理论与可拓学方法,对大规模定制的典型机械产品进行基于数据库的可拓分类知识挖掘,建立满足产品个性需求性能的可拓配置变换规则、关联函数及与之对应的产品可拓配置集等,并将其有效地应用到单体液压支柱的个性化配置设计中.应用实例表明:该方法不仅能快速满足大规模定制设计的个性化要求,而且能为计算机参与解决配置设计矛盾问题提供一种可行的途径.

Extensible configuration design for products of mass customization based on knowledge

As the study on customer performance demand is not sufficient in existing product configuration design method,the extensible configuration design theory and method based on knowledge is put forward.With full analysis of information processing during product design process and better understanding of how to develop knowledge based design systems,matter element theory and extension logic method can be applied to database based extension classification knowledge mining for typical mechanical products of mass customization.Then extensible configuration design rules to satisfy individual performance requirements of products,relational functions and corresponding extensible configuration sets are established in order to effectively use in new product scheme design.Finally,the method is first used in individual configuration design of single hydraulic props,and the fact is so apparent in the experiment that the method not only meets individual requirements fast to satisfy mass customization design,but also provides a feasible approach to let the computer solve contradictory problems during configuration design.
