摘要： Methods and related program product for assessing and optimizing metrology instruments by determining a total measurement uncertainty (TMU) based on precision and accuracy. The TMU is calculated based on a linear regression analysis and removing a reference measuring system uncertainty (URMS) from a net residual error. The TMU provides an objective and more accurate representation of whether a measurement system under test has an ability to sense true product variation. The invention also includes a method for determining an uncertainty of the TMU.

摘要： Combining of reference measurement collections (RMCs) of at least three reference measurement systems into a weighted reference measurement collection (wRMC) is disclosed. Each RMC includes a plurality of corresponding sample measurements, each of which has a measurement value of the same sample. The invention plots corresponding measurement values to generate a plurality of data pairs for each possible RMC pairing. A best-fit line of the plurality of data pairs for each RMC pairing is then generated, and a residual for each data pair is calculated. A weight is then assigned to each sample measurement for each RMC based on the residuals associated with a respective RMC to which the sample measurement belongs, favoring a smaller residual more than a larger residual. A weighted reference measurement is then generated based on the weights, and the measurement value for the respective sample measurement for each RMC.
摘要翻译：公开了将至少三个参考测量系统的参考测量集合（RMC）组合到加权参考测量集合（wRMC）中。每个RMC包括多个对应的样本测量值，每个测量值具有相同样本的测量值。本发明绘出相应的测量值以产生用于每个可能的RMC配对的多个数据对。然后生成用于每个RMC配对的多个数据对的最佳拟合线，并且计算每个数据对的残差。然后根据与样本测量所属的相应RMC相关联的残差，将权重分配给每个RMC的每个样本测量，有利于比较大残差更小的残差。然后基于权重和每个RMC的各个样本测量的测量值生成加权参考测量。
