Opis:
Calculations of water distribution systems are most often performed many times because the correct solution from a technical point of view is rarely obtained after the first calculation run; hence, we can talk about a multistage calculation process. In connection with this, the calculation process of computer water distribution systems can be additionally supplemented with elements of process diagnostics. Diagnostic activities should be carried out using numerical algorithms, which can be a complement to classical hydraulic calculations of water distribution systems. The condition for reliable functioning of the diagnostic system formulated in this way is the efficient detection of computational irregularities. For this purpose, diagnostic problems were defined for the water pipes and the connection nodes in the water distribution system. The proposed diagnostic tests analyze the calculation results and indicate whether the solution is correct or, if irregularities are detected, suggest a way to solve the problem. Diagnostic tests are carried out using artificial neural networks.

Opis:
Hydraulic calculations of water distribution systems are currently performed using computer programs. In addition to the basic calculation procedure, modules responsible for evaluating the obtained calculation results are introduced more and more often into the programs. This article presents the results of research on artificial neural networks with a radial base function (RBF) and a multilayer perceptron (MLP), aimed at determining whether they can be used to model the relationship between the variables describing the computational section of the water distribution system and the diameter of the water pipe. The classification capabilities of the RBF and MLP networks were analyzed according to the number of neurons in the hidden layer of the network. A comparative analysis of RBF networks with multilayer perceptron (MLP) networks was performed. The results showed that the MLP networks have much better classification properties and are better suited for the task of assessing the selected diameters of the water pipes.
