Abstract

Extreme rainfall increasingly threatens the safety and service continuity of urban gas systems by inducing flooding, secondary hazards, facility failures, supply disruptions and leakage risks. Existing risk-oriented approaches are insufficient for capturing the multi-stage resilience of gas systems under flood-disaster scenarios. This study develops an integrated resilience assessment model that links flood-disaster impacts with the functional maintenance, restoration, and adaptive improvement of urban gas systems. A three-dimensional indicator system is constructed from the perspectives of resistance, recovery, and adaptation. A combined weighting scheme integrating stochastic multi-criteria acceptability analysis, the analytic hierarchy process, and game-theoretic aggregation is then developed to balance data-driven variation and expert judgment, and the VIKOR method is used for compromise ranking. An empirical analysis of four administrative districts in a representative city in North China shows that resilience follows the order District C > District D > District A > District B, consistent with the SMAA-based ranking. The proposed model can identify regional resilience disparities and dimension-specific weaknesses, providing methodological support for flood-risk prevention, emergency resource allocation, and resilience enhancement in urban gas systems.
