Research and estimation situational causally - to inquisitional model of indexes of functioning of gasdistributing network at nonpermanent situations

The paper posed and solved the problem of formalizing and assessing causal model of decision-making for the expert analysis of indicators of the functioning of the gas distribution network in the emergency situations. Information features and specifications of gas supply systems determine the priority requirements, which are aimed at carrying out the identification and assessment of the quality of their technical and technological parameters predetermining conditions to ensure the uninterrupted supply of gas to consumers, security, simplicity and convenient maintenance. The results of computational experiments determine the options to take effective decisions on the regulation of the gas flow distribution in the network.
