| Summary: | Relevance of the work is caused bythe need to improve the efficiency of the physical protection system of linear part of the main oil pipeline (LCh MN) from committing acts of unlawful interference, in particular from 2003 to 2012, 4779 facts of unauthorized connection to the linear part of the main oil pipeline was revealed at the facilities of OJSC «Transneft». The main aim of the study is to develop a mathematical model for risk management of physical safety for the linear part of the main oil pipeline, implementing the principles of GOST R ISO/IEC 31000-2010. The methods used in the study: matrix and linear analysis, statistical analysis of the distribution of risk events, methods of ranking, statistical hypothesis testing. Results. The authors have developed the method of controlling the amount of physical safety risk for spatially extended objects such as the linear part of the main oil pipeline. The paper introduces the structural mathematical model that realizes physical safety risk management in accordance with the principles of GOST R ISO/IEC 31000-2010. On this basis, we consider the method of resource allocation in time and parts of the linear part of the main oil pipeline between several units, ensure the protection of a single main oil pipeline. The paper describes the procedure of dynamic adaptation of the mathematical model parameters at entry of data on committed acts of unlawful interference, as well as the results of the verification activities in their simulation. The authors analyzed the spatial and temporal distribution of the physical safety risk and the potential to reduce the risk of the 100 km area of the «Aleksandrovsky-Anzhero-Sudzhensk» linear part of the main oil pipeline and compared the potential to reduce risk of the actual control measures and the measures proposed to conduct when using the developed management technique. The paper shows the increase of the risk-reduce potential by 1 million 169 thousand rubles and demonstrates the compliance management efficiency by 26 % by providing more uniform distribution of control measures on sections of the linear part of the main oil pipeline. |
