Sizing of technical networks of urban utilities systems [articol]

Abstract

The review paper presents the general scope of technical engineering and optimization methods of the most important urban utilities facilities: water supply and gas distribution networks functioning in open circuits, heating and electrical distribution networks respectively, functioning in closed circuits. From the previously undertaken studies, it comes out the version with the most favorable technical and economical exploitation conditions. In the case of large systems, two or even several versions are analyzed in order to determine the optimized solutions. The paper illustrates the most important documentations sources and results obtained from using urban networks optimizations software, additionally, the optimization models of virtual transitions and the obtained outcomes are presented.
