The Principles of Evaluating the Economic Feasibility of Expenses for the Creation and Maintenance of the National Measurement Standards at the Required Level

In the recent years, the problem of evaluation of the economic feasibility of investments in the development of international and national metrology infrastructures has become the target of intensive research in many countries of the world. Particular attention is paid to the justification of the best option from the economic point of view of creating and maintaining(operating) at the proper level the top element of the metrology system of a certain country -the national measurement standards. The purpose of the present paper is the further development of the approach proposed in the NSC "Institute of Metrology", that is based on comparing the expenses for transfer the required accuracy of reproduction of the units of physical quantities (PhQ), depending on where PhQ is reproduced: by the national primary measurement standard or foreign one. New versions of algorithms for evaluating the economic feasibility of creating (improving) and maintaining the national primary measurement standards at the required level are considered, taking into account the need for their international recognition (the need for participation in international comparisons), the previously developed algorithms have been modified to take into account the influence of inflation processes on the economic indicators of metrological activity.
