Description
Summary:This paper considers a problem of source data uncertainty concerning the technical state of gas supply systems. Decision-making in the region of managing and development planning of the gas supply systems (production, transport, distribution, storage), as a rule, occurs by lacking of information, and the validity of some data is questionable. We propose to formalize the information uncertainty in terms of membership functions of the fuzzy sets. Mathematical models and algorithms for solving the various modelling and optimization problems of the natural gas transport are worked out. The results of calculations demonstrate the potential of the technique. •Fuzzy models for the technical state parameters of pipelines and compressors.•An algorithm for calculating the maximum flow capacity of a gas-transport system with fuzzily-assigned parameters.•An optimization algorithm of the operation modes of a gas transport system with fuzzily-assigned parameters.•Application of the proposed models and algorithms to the illustrative and real-world gas transport systems.
