Simulation-based analysis has been used for planning, control, and decision-making support of physical internet enabled logistics networks. However, multiagent modelling and simulation based on micro-level interactions have been rarely developed for the pre-studies of digital transformation of urban rail transit systems. This hinders a wider industrial deployment of agent technology in the physical internet enabled transport infrastructure. To fill in this knowledge gap, this work presents an agent-based simulation that explicitly models the micro-level protocols of mobile recourse units and their interaction with the physical infrastructure in a rail-road intermodal transport network. Parameterisation of the simulation model is changeable to examine the influences of different efficiency factors. This allows understanding of which structural functions and resource configuration would make an impact system-wide. Through a practical application, a multiagent system is developed for modelling and analysis of sustainable logistics with individually operated mobile resource units. An agent-based simulation assessment is performed to quantify the improvement options. The results reveal that the physical internet can prevent trucks from empty driving, which has a positive effect on the sustainable logistics operations. The proposed model can be used to support the deployment and planning of digital transformation that could be implemented in urban rail transit systems serving urban distribution and passenger transport.

启用互联网的物理铁路多式联运系统的多主体建模和仿真

基于仿真的分析已用于支持物理互联网的物流网络的计划,控制和决策支持。但是,对于城市轨道交通系统的数字化转换的预研究,很少基于微层次的交互作用进行多主体建模和仿真。这阻碍了代理技术在支持物理互联网的传输基础架构中的更广泛的工业部署。为了填补这一知识空白,这项工作提出了一个基于代理的模拟,可以对移动资源单元的微观协议及其与铁路多式联运网络中的物理基础结构的交互进行显式建模。仿真模型的参数化是可变的,以检查不同效率因素的影响。这样可以了解哪些结构功能和资源配置会对整个系统产生影响。通过实际应用,开发了一个多代理系统,用于通过单独操作的移动资源单元对可持续物流进行建模和分析。执行基于代理的模拟评估以量化改进选项。结果表明,物理互联网可以防止卡车空驶,这对可持续物流业务产生了积极影响。所提出的模型可用于支持数字化转型的部署和规划,该数字化转型可在为城市配送和客运提供服务的城市轨道交通系统中实施。开发了一个多主体系统,用于通过单独操作的移动资源单元对可持续物流进行建模和分析。执行基于代理的模拟评估以量化改进选项。结果表明,物理互联网可以防止卡车空驶,这对可持续物流业务产生了积极影响。所提出的模型可用于支持数字化转型的部署和规划,该数字化转型可在为城市配送和客运提供服务的城市轨道交通系统中实施。开发了一个多主体系统,用于使用单独操作的移动资源单元对可持续物流进行建模和分析。执行基于代理的模拟评估以量化改进选项。结果表明,物理互联网可以防止卡车空驶,这对可持续物流业务产生了积极影响。所提出的模型可用于支持数字化转型的部署和规划,该数字化转型可在为城市配送和客运提供服务的城市轨道交通系统中实施。这对可持续物流业务产生积极影响。所提出的模型可用于支持数字化转型的部署和规划,该数字化转型可在为城市配送和客运提供服务的城市轨道交通系统中实施。这对可持续物流业务产生积极影响。提出的模型可用于支持数字化转型的部署和规划,该数字化转型可在为城市配送和客运提供服务的城市轨道交通系统中实施。
