Postnikov I., Stennikov V. Modifications of probabilistic models of states evolution for reliability analysis of district heating systems // Energy Reports. Vol.6. No.2. 2020. P.293-298. DOI: 10.1016/j.egyr.2019.11.077 The analysis and synthesis of reliability of energy systems, particularly district heating systems (DHS), is based on probabilistic modeling of different system states and events connecting these states (usually, these are failures and restoration of system components). The paper...

The concept of solving the problem is based on the average reliability parameters of components (failure and restoration rates) which determine the first approximation to the optimal solution. This parameters needs for the further distribution its average values among system components. Algorithm and mathematical models for determine of optimal reliability ...
