The issues of creating a method for solving a multi-criteria task of the importance and risk (hazard) assessment of trunk pipeline objects (sections) are considered. The method is developed on the basis of the analytic hierarchy process. Each object (section) of trunk pipelines is characterized by a set of particular criteria that have their own scale of possible values of different physical nature and different dominance in determining the overall object importance. In this regard, there is a problem of transition from estimates by physical parameters to dimensionless assessment using some membership function. The study proposes an approach to automating the process of assessing objects by particular parameters in the analytic hierarchy process. For this purpose, a method is proposed that allows experts to be excluded from the process of filling in the paired comparison matrix based on the formation of a system of rules. Having a vector of criteria importance and guided by a system of rules, it is enough to specify the actual values of criteria for each alternative to compare objects. Based on this method, a model has been developed that allowed experimental studies to be carried out in the developed software. This method, as well as the developed importance assessment and decision-making software, is used in the automated system of electrochemical protection of main pipelines. The results of evaluating the importance of criteria for the task of risk assessment of gas pipeline sections are presented. The results obtained and their practical implementation in the management of main gas pipelines confirmed the effectiveness of the developed method. This allows you to make decisions in situations where it is necessary to carry out a multi-criteria selection of currently effective solutions and management strategies, assess risks, prioritize elements and coordinate actions for modernization or development.
