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

Evolutionary game analysis of community elderly care service regulation in the context of “Internet +”

“…is often applied to study complex systems and analyze evolutionary trends (53)(54)(55). Some authors recently used system dynamics to simulate and analyze evolutionary game problems (56)(57)(58). In this study, SD was incorporated into the study of the omnichannel feedback mechanism of elderly people to clearly depict the complex relationships and mechanisms of interaction among the subjects.…”

Benefiting signatories at others’ expense: Effects and spatial spillover of local emergency cooperation agreements in China

“…Cross‐regional cooperation not only exists to implement emergency reinforcement for the neighboring government but also to deal with the fluidity and extensiveness of crises (J. Liu et al, 2022). Simulation analyses showed that cross‐regional cooperation is conducive to resource mobilization and transportation, thus improving the effectiveness of crisis response (Lv et al, 2018; Qiu et al, 2021; Shao et al, 2018; A. Wang et al, 2021). In practice, cooperation frameworks and agreements are employed to instructed localities to better understand and respect each other's roles and responsibilities when formulating collaborative emergency management plans (Mcguire & Silvia, 2010).…”

“…For instance, Boin et al [12] and Mehrtash et al [13] discussed the importance of crossregional coordination mechanisms through cost-beneft analysis under sudden cross-regional disasters. Pescaroli et al [14] and Qiu et al [15] put forward suggestions on how to construct emergency rescue synergistic processes. Urrutia et al [16] used generalized network autoregressive to interdict potential higher infection areas.…”
