Abstract

In recent years, new concepts such as synchromodality have emerged to help carriers better leverage existing capacities and assets to achieve environmental and socio-economic sustainability. Synchromodality is a vast concept. It involves the intelligent utilization of various transport modes. Its main objective is to enhance the freedom and flexibility to switch between transport modes at transport network nodes. The emergence of synchromodality can be facilitated by optimization and simulation models associated with a sharing web service for decision-making. This article studies the concept of synchromodality in the scientific literature and highlights approaches using simulation and optimization techniques. The major challenge of this study lies in the effective implementation of synchromodality concept in practice, while respecting the instructions and constraints set by freight transport stakeholders from a more generic point of view. For that, we present an implementation of the modal shift on the Seine Axis Corridor. A simulation-optimization framework is proposed to generate reliable transport solutions based on the user preferences and environmental considerations. Finally, we resort to sensitivity analyses to assess the impact of variation of service times.

同步货运的优化模拟方法
近年来,出现了同步协调等新概念,以帮助承运商更好地利用现有能力和资产,实现环境和社会经济的可持续发展。同步多式联运是一个庞大的概念。它涉及各种运输方式的智能利用。其主要目的是提高在运输网络节点切换运输模式的自由度和灵活性。与决策共享网络服务相关联的优化和模拟模型可以促进同步多式联运的出现。本文研究了科学文献中的同步模式概念,并重点介绍了使用模拟和优化技术的方法。这项研究的主要挑战在于如何在实践中有效实施同步性概念,同时尊重货运利益相关者从更普遍的角度出发所设定的指示和限制。为此,我们提出了塞纳河轴走廊的模式转换实施方案。我们提出了一个模拟优化框架,以根据用户偏好和环境因素生成可靠的运输解决方案。最后,我们通过敏感性分析来评估服务时间变化的影响。
