Probabilistic simulation model of resilience assessment of natural gas pipeline systems

Abstract The study for the natural gas pipeline system (NGPS), particularly about resilience evaluation, is still in its early stages. Resilience a hot point most important aspects of security assessment. An integrated simulation model presented assessing supply NGPS, incorporating topological and operational circumstances. This takes different forms disruptions into consideration. Analysis done on properties probabilistic disturbances. novel ideas include global temporal as indicators evaluating resilience. By integrating maximum flow algorithm shortest path with structural parameters, volume routes were determined before after Based theories complex network graph theory, researchers have moved traditional viewpoint from entire to affected regions. use models research can facilitate development pre-warning systems including optimization amount arrangement, well formulation maintenance strategies. In addition, also support rapid analysis disturbance results, thus improving accuracy evaluation NGPS.
