Sustainability as valid composition of efficiency and reliability

Abstract

Sustainability as an integral attribute of systems, processes, activities or states gains exceptional attention while analyzing the efficiency and reliability of the mentioned objects, also while fostering management possibilities and developing management principles. To tell the truth, sustainability as an attribute of the mentioned objects has not got yet any unambiguous content and does not have neither the scale, nor dimension of the unified quantitative measurement. The paper aims to measure the sustainability of a system, process, activity or state using a valid composition of efficiency and reliability of the mentioned object. The idea of utility function perfectly suits this mission, which determines the reliability or simply guaranty of every possibility of object existence result. In many fields of practice and science the product of the magnitude and reliability of effect exist-ence is used to apply as an adequate expression of integration of efficiency and reliability indicators. In the paper the application of this methodical principle is practically illustrated by the preparation of the mechanism for small country development universal sustainability possibilities’ analysis and realization. In the paper particular attention is paid to the optimal resource allocation among the implementation of social-demographic, economic, ecological and technological objectives, determining the general success of country development. The concept and scheme of rational resource allocation under conditions of uncertainty is presented.
