OPTIMAL MANAGEMENT OF DEVELOPMENT OF ENGINEERING NETWORKS

The significant volume of construction of various types of pipeline engineering networks in our country makes the task of optimal management of their development one of the most pressing, which in the literature [1, 2.,3] is often called the task of technical and economic calculation of networks at the design stageю Even a small (5-10%) reduction in the amount of reduced costs for the construction and operation of heat, water and gas supply systems on a national scale can lead to a major national economic effect. When designing utility networks, problems of structural and parametric optimization arise [9,10]. The first of these comes down to determining a number of structural parameters - network routing, choosing the location of booster pumping stations, throttles, compressors, etc., and when solving the second, for a given structure, it is necessary to determine a multidimensional vector of parameters for each of the active and passive elements included in the structure. In reality, by combining any sequence of selection of various structures and conducting parametric optimization, for each of them it is possible to find an optimal engineering solution for the network, choosing one or several [10,17] optimization criteria. It should be noted that in a number of cases, due to the inconsistency of the optimization criteria (for example, the criterion of maximum reliability in principle contradicts the criterion of minimum capital investment), problems of multi-criteria optimization arise, for the solution of which a number of methods have been proposed [8], but further research and development are required, as well as their widespread implementation in the practice of designing and operating utility networks.
