摘　　要：在新一代产品几何技术规范(Next Generation Geometrical Product Specification and Verification,NGGPS)不确定理论基础上,分析各种不确定度之间的关系,重点讨论不确定度管理(Procedure for Uncertainty Management,PUMA)测量不确定度管理程序所涉及的贡献因素、评定模型和评定关系等关键环节。设计不确定度管理程序,实现贡献因素分析、不确定度自动计算和系统评价,为实现不确定度评定管理的规范统一奠定基础。Based on the theory of uncertainty, analyzed the relationship between various uncertainty,then emphatically discussed the key links such as contributing factors, evaluation models and evaluation relationship in Procedure for Uncertainty Management （PUMA）. The procedure for uncertainty management was designed to realize the analysis of contributing factors,the automatic calculation of uncertainty and system evaluation. It helps realize the standardization of uncertainty evaluation and management.
