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 adjustment function using uncertainty as an economic tool.
