A System Dynamics Model of Multi-Airport Logistics System under the Impact of COVID-19: A Case of Jing-Jin-Ji Multi-Airport System in China

The development of a multi-airport logistics system (MLS) is closely linked to factors such as regional economy, international and domestic trade, competitive synergies between airports, the impact unforeseen events COVID-19 outbreak. There are various causal relationships feedback loops within MLS, it always in dynamic state change, so ideal use dynamics model depict MLS. Taking Jing-Jin-Ji MLS an example, consisting economy subsystem, trade airport cluster subsystem constructed, sustainable studied by simulating three pandemic scenarios with different levels. At same time, policy simulations sensitivity analyses used find effective strategies enhance results can provide method for forecasting air cargo volumes under basis relevant departments formulate policies
