With sustainability engineering to sustainability efficiency

Abstract

This paper is an attempt to perceive the universal sustainability, when it comes to a discrete country or region, where actually the religious, political, social-demographic, economic, environmental, creative, technological and investment subsystems are revealed not only through the vitality of spiritual and material existence medium, but maybe through the signs of the development of these subsystems as self-assembled units of through the erosion of their interaction. In the article the possibilities of sustainability subsystems’ portfolio, as contemporary systemic analysis means are used. With the help of the expert methods and techniques of portfolio methodology, the problem of optimal allocation of investment resources among the separate sustainability’s subsystems is being solved, which will enable to achieve the enshrined universal sustainability standards. As the universal sustainability index for the country, the particular index composition of that country’s sustainability subsystems’ indices was chosen. The index in the dynamics is perceived as a random process. While projecting its state and evaluating its power, i.e. the impact of subsystem efficiency in a particular moment, this power is measured by the level of the index and the reliability or guarantee of the respective level. To solve the problem of investment resources allocation the idea of Markowitz Random Field was invoked in order to reach the maximum power of sustainability index, and for the technical solution the system of simulation models and decisions “GoldSim” was applied.
