This research focuses on the modeling, analysis, and optimization of resource supply systems within complex systems. It aims to develop accurate mathematical models to characterize the dynamics of resource provisioning, allocation, and consumption. Subsequently, employing systems analysis, simulation, and data-driven methods to evaluate their efficiency, resilience, and sustainability. The ultimate goal is to design intelligent optimization strategies and decision-support tools to enhance resource configuration efficiency, ensure system stability, and provide a theoretical foundation and practical solutions for coping with demand fluctuations, uncertainties, and external disruptions.
