Haw to resolve the conflict between accuracy and reliability, completeness and timeliness of measurement information

Abstract

The focus of metrological science on accuracy as a key property of measurement information (MI) does not meet the needs of practice, which are much broader and include reliability, timeliness, completeness and other properties. Recently, these properties are included in metrological standards, but this is more a declaration than real practice. It is shown that there are contradictions between accuracy and other properties of MI. To involve them into metrology is possible by changing the logic and coordinate system, with the inclusion of an optimal control solution and an action leading to a result like Shewhart-Deming cycles.
