ABSTRACT

City logistics pooling seems to be a promising solution to optimise urban freight transportation. Pooling is a kind of resource sharing in which the ultimate objective is to share the available resources through the active collaboration of all involved stakeholders. Several articles propose VRP-type models and methods to optimise the routing with pooling. Nevertheless, few studies focus on the impact of operational constraints in front of pooling. The main aim of this study is to fill this gap. To this end, we first identify the operational constraints against the implementation of pooling in city logistics. We then use a two-step approach based on mathematical modelling to evaluate the scenarios defined according to the identified constraints. Finally, we set several new indicators to quantify the impacts of these constraints on pooling efficiency. The proposed approach has been tested using real data raised from the literature for the city of Bogota, Colombia.

摘要

城市物流池化似乎是优化城市货运的一个很有前景的解决方案。池化是一种资源共享，其最终目标是通过所有相关利益相关者的积极协作来共享可用资源。一些文章提出了 VRP 类型的模型和方法来优化路由池。然而，很少有研究关注池前操作限制的影响。本研究的主要目的是填补这一空白。为此，我们首先确定了在城市物流中实施汇集的操作限制。然后，我们使用基于数学建模的两步方法来评估根据确定的约束定义的场景。最后，我们设置了几个新指标来量化这些限制对汇集效率的影响。所提出的方法已经使用从哥伦比亚波哥大市的文献中收集的真实数据进行了测试。
