Fuzzy Evaluation Models for Accuracy and Precision Indices

نویسندگان

چکیده

The random variable X is used to represent the normal process containing two important parameters—the average and standard deviation. transformed using Y = (X − T)/d, where T target value d tolerance. of then called accuracy index, deviation precision index. If only values index are well controlled, quality level as yield ensured. Based on this concept, paper constructed a control chart for derived confidence intervals in-control data, was stable. This aims via monitoring process. At same time, fuzzy tests developed indicators evaluate whether can reach k-sigma level, offer suggestions about directions improvement when it fails level. Obviously, model in cannot meets requirements level; also provide decision regarding should be improved. It very helpful enhancement enterprises’ capabilities.

Developing a Method for Increasing Accuracy and Precision in Measurement System Analysis: A Fuzzy Approach

Measurement systems analysis (MSA) has been applied in different aspect of industrial assessments to evaluate various types of quantitative and qualitative measures. Qualification of a measurement system depends on two important features: accuracy and precision. Since the capability of each quality system is severely related to the capability of its measurement system, the weakness of the two...

Fuzzy models for precision measurements

Engineering and scienti c measurement results of continuous quantities are not precise numbers but more or less non-precise. Therefore so-called non-precise numbers are necessary to describe measurement results. Non-precise numbers are special fuzzy subsets of the set of real numbers. For vector quantities so-called fuzzy vectors are the best up to date model for related measurements.
