System dynamics mechanism of cross-regional collaborative dispatch of emergency supplies based on multi-agent game

Abstract The cross-regional coordinated dispatch of emergency supplies is a complex issue involving multiple topics, which covers relationships and affected by variables. In the face severe emergencies, relief inside specific area are far from meeting explosive demand for supplies. Besides, supply materials disaster areas often have spatial mismatch. Considering attributes externalities public goods rescue, there many obstacles Local administration (LAE) logistics enterprises (ELE) spontaneously carrying out across regions. To solve this complexity problem, research abstracts higher-level (HAE), LAE ELE as main stakeholders, with tripartite evolutionary game (ETG) model system dynamic (SD) constructed to analyze mechanism carry numerical simulation three-party process. All analyses tests in study proved that strong supervision HAE has decisive impact on realization supplies, financial rewards punishments imposed other entities can accelerate or delay achievement equilibrium strategy. However, when chooses not regulate, cooperation willingness affects lot all stakeholders will eventually reach at (1,1,1) only if actively
