摘　　要：为了有效辅助设计者进行产品创新设计,实现知识共享与重用,提出一种基于用户模型,面向产品创新设计的个性化知识推送模型,在该模型中知识推送机制为:首先由设计任务促发知识推送规则,为其匹配设计知识,生成预推送知识集,知识推送规则为利用粗糙集理论从使用日志中进行抽取;然后利用本体技术构建用户模型,获取用户知识需求,对预推送知识集进行过滤和排序,实现满足设计任务和设计者知识需求的个性化知识推送。以重载铁路扣件改进为示例,表明了该模型的有效性。In order to assist thel designer to carry out product innovation design and realize knowledge sharing and reuse, a personalized knowledge push framework based on user model for product innovation design was proposed. The following was the knowledge push mechanism： First, generated the pre push knowledge sets, the product innovation design process promoted the knowledge push rides which was extracted from the use of log by using rough set theory to match the design process with design knowledge; Then, filtered and sorted the pre push knowledge sets according to user knowledge requirement based on the user model; Thus, the need of personalized knowledge push was realized~ Finally, the application for the improvement of the heavy haul railway fastener proved the validity of the model.
