A New Approach to Generation of Measurement Methods

Bojan P. Troianov, Emil K. Donchev

Abstract

In this paper two logical levels of the measurement procedure are discussed: physical level, on which the magnitude of a measurand is equated with the magnitude of a material measure; formal level, on which a value is assigned to the measurand. There are three types of logical functions involved in the measurement procedure: introduction of measurand and metric; change of quantity. Depending on the number of particular quantities, two models are proposed: two quantities are involved - measurand and material measure; three quantities are involved - measurand, material measure and one auxiliary constant quantity. According to SI all possible operations are described by an additive algebra. Based on possible physical interactions between quantities, common variants have been synthesized for creation of measurement methods. The second model allows proposing a class of methods based on using an inversion. The proposed approach allows coverage of all possible measurement methods applicable to the measurement of extensive quantities.
