“…The international community acknowledges the significance of studying migration dynamics, and system dynamics modeling provides a valuable approach to analyze the complex structure of migration systems. Simulations allow researchers to test hypotheses and understand the impact of modifying components, depicting migration as a system involving personal, social, and organizational elements [ 46 , 47 ].…”

The underground logistics system is a relatively new concept for container transportation, which is designed to reduce the congestion and pollution on the road caused by the sharply growing number of collections and distributions of containers in the port cities. This paper considers a system where some underground logistics vehicles (ULVs) are marshaled and used to transport containers between two port terminals through a deep underground tunnel. Automated guided vehicles (AGVs) are used for horizontal transportation of containers in the above-ground yard of the terminals, and yard cranes (YCs) are used to transfer the containers vertically through a shaft linking the above-ground yard and the deep underground tunnel. To guarantee the efficiency of this system, a joint scheduling problem of the YCs and the ULVs is proposed and formulated as an integer programming model to minimize the total waiting time of the YCs and ULVs. Taking marshaling and congestion of the ULVs into consideration, a Genetic Algorithm is developed to solve the problem. Numerical experimental results prove the efficiency of the proposed algorithm, and different marshaling strategies are compared. Our research provides a scientific foundation for developing underground logistics systems in large port cities.

This paper analyses the profile and mode of operation of the transport industry and finds that a large market, high returns, strong trends, long cycles, large investments and strong competition characterise the transport industry. Based on the theory of policy tools, logistics regulations are classified into three types: supply-type, environment-type, and demand-type, and the cumulative regulatory strength values are measured for each year respectively. By constructing a system dynamics model with sensitivity analysis and regulation interpretation, the effect of optimising logistics regulations on each dimension of the transport industry is studied in depth, and the differences in the effect of different logistics regulations on the operation and management of the transport industry, the infrastructure, the level of economic development, and the level of informatisation are analysed. From the long-term perspective, it seems that optimizing logistics regulations will promote the positive development of the transport industry. As the transport industry continues to improve, environmental and demand-based regulations become less influential on its performance. For every 10 per cent change in environmental and demand regulations, the transport industry is affected by 0.5 per cent as well as 0.7 per cent. When regulations change by 30%, supply-based regulations have the greatest positive impact on the transportation industry’s operational management, infrastructure, level of economic development, and level of information technology. Obviously optimising logistics regulations can better promote the level of transport industry.
