Conflict is ubiquitous in social and economic life and is closely intertwined with human production and daily activities. This paper introduces a restructured three-way conflict analysis model by reformulating and extending the original three-way conflict model. First, we propose the concept of 2-tuple conflict states by integrating voting information with payoff information. Second, we introduce conflict ...

As climate-related disasters intensify, developing effective mitigation and adaptation policies requires measuring the resilience of socio-economic systems. This study proposes a threshold-based resilience measurement framework grounded in input-output disaster analysis. Leveraging a global multi-regional input-output table, we introduce a novel negligible-loss threshold to identify non-resilient sectors ...

Accurate forecasting of renewable energy production and consumption is essential for energy security, carbon neutrality, and the reliable operation of renewable-dominated power systems. However, existing forecasting approaches often struggle to jointly model multivariate renewable energy series under small-sample conditions with pronounced seasonality and nonlinear dynamics. This study integrates dynamic ...

As a generalized extension of fuzzy sets, Pythagorean fuzzy sets (PFSs) provide a sophisticated framework for modeling subjective uncertainty inherent in human cognition. Real-world decision-making systems frequently exhibit concurrent uncertainties characterized by incompleteness and fuzziness. This work synthesizes grey system theory with PFSs to establish grey Pythagorean fuzzy sets (GPFSs), a novel ...
