摘　　要：工艺质量知识是设计决策支持知识的重要组成部分。为设计者提供所需的工艺质量知识有助于设计决策的有效性。在分析机械电子产品设计活动的基础上,详细阐述了设计活动和设计方法的工艺质量知识需求。采用IDEF0方法建立设计活动模型证实了支持设计活动的工艺质量知识流。在此基础上,运用UML方法构建了工艺质量知识对象模型,该模型支持工艺质量知识的获取、组织和管理,可以为设计决策提供不同层次和粒度的工艺质量知识。Process Quality Knowledge （PQK） is very useful for supporting design decision-making. The effectiveness of design decision-making is improved by providing needed PQK to designer. Generic product design activities of mechanism and electronics were analyzed and the needed PQK of design activities and design methods is described in detail. Then, a design activities model was developed using IDEF0, in which the flow of PQK supporting design decision-making was identified. PQK＇s object model was developed adopting UML method based on the activities model. The model supports PQK＇s acquisitions, organization and management. It also provides PQK for design decision-making of multiple level and granularity.
