Optimality criteria for technicoeconomic substantiation of projects
Conclusions 1. If the total capital investments and annual expenditures, including the closing investments and expenditures for the individual project or element of the hydropower installation, are continuous functions of a certain parameter determining them, a dimensions for instance, then its value yielding the minimum amortized costs corresponds to the adopted normative coefficient of efficiency of the additional capital investments, which makes it possible to express the utilized economic optimality criterion in the form of Eq. (4). 2. The point of the minimum amortized costs yields the limiting allowable value of the parameter sought for the normative efficiency of the additional capital investments. 3. Specific engineering solutions may have, not only the normative efficiency but also an increased efficiency, which may be determined by singling out the economically determined region of variation of the parameter sought. Singling out such a region expands the possibilities of selection for the designers and, under certain conditions, may contribute to reduce the volumes of work, capital investments, and labor.
