Optimizing water delivery to consumers with multi-mode and uncertainty into account.

In the work under consideration, the water distribution and distribution system was optimized using linear programming method. This includes issues of establishing restrictions for network systems at the required intervals, taking into account zoning and control in ring networks, multi-criteria optimization, establishing restrictions on the supply of water to consumers, and ensuring equality of diameters of parallel sections. Along with this, the optimization issue related to the uncertainty of average daily water consumption was also considered. The exact values of the variables of the summation function for a given problem and the results of "deterioration" of the solution in case of deviation from these values are determined. After this, the question of approximating the calculated variables to the desired ones is considered. For a given value of the aggregate function, the problem of synthesizing water distribution and a system for distributing water demand has been solved. For the same values of the aggregation functions, the vector of node costs is determined. In order to maximize the aggregation function, the system parameters were determined and optimized using the linear programming method. An aggregation function was constructed for the resulting solution. Based on stochastic calculations, a method for stochastic optimization of the water distribution and distribution system was developed, on the basis of which the mathematical expectation of functions with economic indicators that have certain probabilistic properties was minimized.
