摘要

目的 大规模疫苗接种活动的规划通常由非政府组织负责,它们必须面对在最短时间内为最多人数接种疫苗的严峻挑战。本文提出了一个线性数学模型,该模型将位置、日程安排和路线决策结合在一起,可以确定疫苗接种中心的位置,以及每个医疗小组必须遵循的日程安排/路线,以便在最短时间内满足目标需求。此外,本文还提出了一种可集成到电子表格中的启发式方法。结果如数值实验所示,所提出的启发式方法能在短时间内提供良好的解决方案。社会影响将启发式方法集成到电子表格中,为决策者提供了一个简单高效的工具,同时避免了用户组织对信息系统基础设施的大量投资。原创性/价值受现实问题的启发,与以往的研究不同,规划的目标是利用现有资源缩短疫苗接种活动的时间,确保目标覆盖率,而不是规划成本最小化或覆盖率最大化。此外,为了帮助实践者实施,启发式方法可以在电子表格中求解。

Heuristic algorithm tool for planning mass vaccine campaigns
Purpose The planning of massive vaccination campaigns often falls to nongovernmental organizations that have to face the critical challenge of vaccinating the largest number of people in the shortest time. This study aims to provide an easy tool for minimizing the duration of mass vaccination campaigns in rural and remote areas of developing countries. Design/methodology/approach This paper presents a linear mathematical model that combines location, scheduling and routing decisions that allows determining where to locate the vaccination centers, as well as the schedule/route that each medical team must follow to meet the target demand in the shortest time possible. In addition, the paper proposes an heuristic approach that can be integrated in a spreadsheet. Findings As the numerical experiments show, the proposed heuristic provides good solutions in a short time. Due to its simplicity and flexibility, the proposed approach allows decision-makers to analyze and evaluate several possible scenarios for decision-making by simply playing with input parameters. Social implications The integration of the heuristic approach in a spreadsheet provides a simple and efficient tool to help decision-makers while avoiding the need for large investments in information systems infrastructure by user organizations. Originality/value Motivated by a real-life problem and different from previous studies, the objective of the planning is to reduce the length of the vaccination campaigns with the available resources and ensure a target coverage instead of planning for minimizing costs or maximizing coverage. Furthermore, for helping implementation to practitioners, the heuristic can be solved in a spreadsheet.
