摘　　要：降低成本求解是一个复杂的基于知识的推理过程,科学的知识表示结构是合理推理的基础。从阐述全生命周期机械产品成本项目组成及特点入手,分析了各成本项目成本降低知识的特点,提出了采用符合其特点的分层次的框架式方法表示成本降低知识,描述了如何在数据库中具体实现框架式成本降低知识表示。In product design process, cost reduction is a complex solution procedure based on knowledge reasoning. Scientific knowledge representation is the basis of the logical consequence. Based on the expatiating of the components and characteristic of the whole lifecycle cost of mechanical product, the characteristic of cost reduction knowledge was analyzed. The frame method to adopt different layers suitable for its characteristics was presented to express the cost reduction knowledge. The realization of the framework -based knowledge representation in database was also described.
