ALGORITHMS FOR CONSTRUCTING AND CALIBRATING ELECTRONIC MODELS OF WATER SUPPLY SYSTEM

Subject: the deterioration and technical condition of water supply and drainage pipelines in most of Russia’s settlements, the limitation of material resources for their restoration and renovation in conditions of housing and communal services reform, require a scientifically grounded approach to the reconstruction and modernization of these systems [1-4]. To solve these problems, the Government of the Russian Federation approved and introduced normative documents1, 2. According to them, the development of centralized water supply and water disposal systems is carried out only in accordance with the general schemes of these systems3. As part of these schemes, it is necessary to develop an electronic model of a centralized water supply and disposal system for an objective assessment of the impact of activities aimed at optimizing their work [5]. The algorithm for constructing and calibrating the electronic model of the city’s water supply system is the subject of this study. Research objectives: development of a methodology for constructing electronic models and algorithms of calibrations which are applicable to the Russian Zulu software. Materials and methods: for an objective assessment of the impact of long-term measures aimed at improving the operation of the water supply network, as well as the development of the city’s water supply system, we use modeling along with the implementation of an adequate electronic model. The adequacy of the electronic model is achieved via its calibration [6]. The object of the research is the water supply system of Minsk and Salavat in the development of electronic models for realization of their development and reconstruction directions. Results: based on the experience of implementation of a number of water supply systems (Ufa, Irkutsk, Penza, Orenburg, Tyumen, Salavat, Minsk), a methodology for constructing and calibrating electronic models was developed; the algorithms applicable to the Russian Zulu software and necessary for construction of models were also developed. Conclusions: the results of the work are implemented on a number of water supply systems in the cities of Russia and can be recommended for application of information technologies in electronic model realization, the assessment and analysis of the functioning of water supply systems and the optimization of their operation.
