大规模定制的知识管理方法

　　【摘要】　为实现产品设计知识的获取、管理和重用, 构建了基于W eb 的设计知识管理体系。对产品配置设计知识、变型设计知识及其过程知识的组织和管理方法进行了研究。根据知识及其表达方法的特点, 提出采用有向图的十字链表法、规则的双向链表和数据库表组织设计知识库, 实现知识检索的导航机制。应用J2EE 技术构建知识库引擎, 结合实例推理和规则推理的方法, 实现知识的智能检索和问题求解, 从而有效支持定制设计的快速实现。 <BR>    关键词: 设计　大规模定制　知识管理方法　基于实例推理 <BR>Abstract：In o rder to m anage and cap tu re the design know ledge du ring p roduct cu stom izat ion design, a W eb2based know ledgem anagem en t system is developed.
