摘要

本文旨在根据受影响地区的优先顺序,研究将横向转运和道路脆弱性纳入人道主义救济链,以解决公平分配问题,并评估各种参数对每个救济项目的总平均膨胀距离的影响。设计/方法/方法在确定综合关键标准和子标准之后,应用混合多标准决策框架来获得真实地震场景中需求点的权重和排名。然后提出并比较了直接装运和横向转运模型。考虑设施选址、库存预置、道路易损性和横向转运数量等因素,建立了混合整数规划模型。研究发现,优先标准和次级标准的使用,加上横向转运和道路易损性,减少了每件救济物品的总平均膨胀距离,从而使救济物品的分配更加公平。据作者所知,本研究是通过需求点优先排序对人道主义反应公平性进行研究的首批研究之一。它还弥合了通常单独处理的两个领域之间的差距:多标准决策和人道主义后勤。实际意义:这是设拉子地区第一个专注于公平分配系统的学术研究,在中等规模地震发生后,考虑到上层的横向转运,对需求点进行优先排序,并向他们分配救援物资。本文阐明了当作者同时面临多个因素(即救济分发中心的位置、库存水平、距离、横向转运和道路脆弱性)时,如何优先考虑需求点以促进人道主义物流的公平性。

A prepositioning model for prioritized demand points considering lateral transshipment
Purpose This paper aims to examine the integration of lateral transshipment and road vulnerability into the humanitarian relief chain in light of affected area priority to address equitable distribution and assess the impact of various parameters on the total average inflated distance traveled per relief item. Design/methodology/approach After identifying comprehensive critical criteria and subcriteria, a hybrid multi-criteria decision-making framework was applied to obtain the demand points’ weight and ranking in a real-life earthquake scenario. Direct shipment and lateral transshipment models were then presented and compared. The developed mathematical models are formulated as mixed-integer programming models, considering facility location, inventory prepositioning, road vulnerability and quantity of lateral transshipment. Findings The study found that the use of prioritization criteria and subcriteria, in conjunction with lateral transshipment and road vulnerability, resulted in a more equitable distribution of relief items by reducing the total average inflated distance traveled per relief item. Research limitations/implications To the best of the authors’ knowledge, this study is one of the first research on equity in humanitarian response through prioritization of demand points. It also bridges the gap between two areas that are typically treated separately: multi-criteria decision-making and humanitarian logistics. Practical implications This is the first scholarly work in Shiraz focused on the equitable distribution system by prioritization of demand points and assigning relief items to them after the occurrence of a medium-scale earthquake scenario considering lateral transshipment in the upper echelon. Originality/value The paper clarifies how to prioritize demand points to promote equity in humanitarian logistics when the authors have faced multiple factors (i.e. location of relief distribution centers, inventory level, distance, lateral transshipment and road vulnerability) simultaneously.

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.
