基于系统动力学的港口集疏运系统仿真模型研究——以广西北部湾港为例

Research on Simulation Model of the Port Collecting and Distributing Transportation System Based on System Dynamics——Take Guangxi Beibu Gulf Port for Example

为模拟仿真港口集疏运协调发展的行为特征和发展趋势,拟运用系统动力学的原理及仿真方法,在系统分析和因果反馈分析的基础上构建广西北部湾港集疏运系统协调发展的系统动力学模型,测定相关参数,以及通过模型结构与行为等检验方法验证该模型的有效性.

In order to simulate the characteristics and development trend of the port collecting and distributing transportation system＇s coordinated development,the principle of the system dynamics and the simulation method are used,This paper constructs the system dynamics model of Guangxi Beibu Gulf Port collecting and distributing transportation system＇s coordinated development based on the system analysis and causal feedback analysis to determine relevant parameters,and verity the validity of the model through some inspection methods such as the model structure and behavior.
