中文摘要：

研究了测量不确定度的统一评定和表述方法，用新一代产品几何技术规范（GPS）基于GUM及系统量化统一的新思路，拓展了测量不确定度的概念，规范了测量不确定度的评定程序。在此基础上，将测量不确定度的概念拓展至GPS系统，利用拓展后不确定度的统计、量化特性，将产品的功能、规范与测量评定量化集成。通过不确定度的经济杠杆调节作用，实现过程资源配置的统筹优化，提高产品的综合效益。

英文摘要：

It expanded the concept of measurement uncertainty, and specified procedure for uncertainty management by using the new thoughts based on the GUM and system quantifying unifying in the new generation GPS. Furthermore, the concept of measurement uncertainty had been expanded to the whole GPS system beyond just measurement, and the functions, specifications and measurement verification of real workpieces were quantified and integrated by using the statistic and quantificational characteristics of expanded uncertainty. The optimum allocation of resources amongst specifications, manufacturing and verification is realized, the total efficiency of products is increased by the adjust ment function using uncertainty as an economic tool.
