A Grey-System Theory Approach to Assess the Safety of Gas-Supply Systems

open access: yesEnergies, 2022
The continuity of gas-supply service is a major concern for all gas-supply operators. A safety review of a gas-supply system could help to mitigate the potential repercussions of supply disruptions. Disruptions occur at random due to systemic failures in
