摘要

目的本文的目的是介绍一个三梯队多式联运问题适用于人道主义物流案例研究,发生在墨西哥。设计/方法/方法本研究开发了一种方法,结合转运问题和多仓库异构车队车辆路线问题的适应,构建了一个包含陆基车辆和无人机使用的数学模型。将该模型应用于2017年9月19日墨西哥地震的案例研究中,采用了Gurobi优化求解器。结果表明,运输成本与交货时间呈负相关关系;另一方面,与使用大型实例相比,使用中型和小型实例的模型在更短的CPU时间内执行。虽然实例的大小限制了模型在大规模问题中的使用,但这种方法设法在自然灾害期间使用无人机进行最后一英里的交付,从而很好地表示了运输网络。原创性/价值本研究建立了一个模型,该模型结合了转运、多个仓库和包括陆基车辆和无人机在内的异构车队的车辆路线问题。文献中存在多种模型来解决这些类型的问题,包括使用这些运输方式;然而,据作者所知,目前还没有类似这项研究的建议。

A multiobjective mathematical model for a humanitarian logistics multimodal transportation problem
Purpose The purpose of this paper is to introduce a three-echelon multimodal transportation problem applied to a humanitarian logistic case study that occurred in Mexico. Design/methodology/approach This study develops a methodology combining a transshipment problem and an adaptation of the multidepot heterogeneous fleet vehicle routing problem to construct a mathematical model that incorporates the use of land-based vehicles and drones. The model was applied to the case study of the Earthquake on September 19, 2017, in Mexico, using the Gurobi optimization solver. Findings The results ratified the relevance of the study, showing an inverse relationship between transportation costs and delivery time; on the flip side, the model performed in a shorter CPU time with medium and small instances than with large instances. Research limitations/implications While the size of the instances limits the use of the model for big-scale problems, this approach manages to provide a good representation of a transportation network during a natural disaster using drones in the last-mile deliveries. Originality/value The present study contributes to a model that combines a vehicle routing problem with transshipment, multiple depots and a heterogeneous fleet including land-based vehicles and drones. There are multiple models present in the literature for these types of problems that incorporate the use of these transportation modes; however, to the best of the authors’ knowledge, there are still no proposals similar to this study.

期刊介绍: The Journal of Humanitarian Logistics and Supply Chain Management (JHLSCM) is targeted at academics and practitioners in humanitarian public and private sector organizations working on all aspects of humanitarian logistics and supply chain management. The journal promotes the exchange of knowledge, experience and new ideas between researchers and practitioners and encourages a multi-disciplinary and cross-functional approach to the resolution of problems and exploitations of opportunities within humanitarian supply chains. Contributions are encouraged from diverse disciplines (logistics, operations management, process engineering, health care, geography, management science, information technology, ethics, corporate social responsibility, disaster management, development aid, public policy) but need to have a logistics and/or supply chain focus. JHLSCM publishes state of the art research, utilizing both quantitative and qualitative approaches, in the field of humanitarian and development aid logistics and supply chain management.
