“…The rational distribution of reliability both on various subsystems and redundancy methods is a complex of problems of the synthesis (optimization) of reliability, which are the subject of separate study in the framework of directions of this work. For example, some of this studies are presented in [43]- [47]. The practical studies presented in the article confirm the effectiveness and applied significance of the previously developed methods and models of the comprehensive reliability analysis of DHS.…”

“…are a subject of special research of the problems of reliability synthesis. For example, the methodology for the optimal increase/ensuring the reliability parameters of DHS components as the one of the problems of reliability synthesis is considered in articles [43] and [44]. Some reliability optimization issues for the DHS with prosumers are presented in works [45]- [47].…”

The general idea of the methodology for the comprehensive reliability analysis of district heating systems (DHS), developed earlier by the author of this paper, is a joint considering and modelling of each technological processes, including fuel supply to heat sources (HS), generation of heat energy by these HS and its distribution on district heating network (HN). For solving this problem different methods and models are applied: statistical testing method, Markov random processes, methods of the theory of hydraulic circuits, basic laws of district heating and heat transfer processes, etc. In this paper the main attention is paid to the results of the practical application of methods and models of a comprehensive reliability analysis of DHS using the example of calculations performed for the actual DHS scheme of the Shelekhov city (Irkutsk region, Russia). Different stages of the case study are considered, including preparation of initial data, simulation modelling of fuel supply to HS, modelling of the Markov random process describing operate of DHS, calculation of post-failure modes in HN, evaluation of nodal reliability indices (RI), decomposition analysis of reliability. Based on the analysis of calculation results some preliminary directions are formulated to the increase of reliability for studied DHS. These data are the basis for a comprehensive reliability synthesis (optimization) of DHS, the solution of which is the subject of special perspective stage in development of the research.

Abstract. At present, there is a growing need to solve the design problem of the hydraulic circuit of an intelligent heating system with the required transmission capacity, hydraulic stability and reliability indices. The paper proposes a mathematical statement of the design problem of such a hydraulic circuit and an original methodological approach to solve it by decomposing a general complex problem into several simpler ones (of a smaller dimensionality). The proposed approach makes it possible to tailor the computational procedure to specific features of a heating system to be modeled.
