This study addresses a healthcare facility location/network design problem considering equity and accessibility. Locating the healthcare facilities, planning the capacity of healthcare facilities, and designing the transfer network are the primary goals of the given problem. The presented model aims to minimize system costs, maximize accessibility, and minimize inequality among all demand nodes. A real-world case study is presented to elucidate the performance and applicability of the proposed model. Moreover, a fix-and-optimize (FO) approach is proposed for tackling the problem on a large scale. The obtained results from experiments on several test problems indicate the efficiency of the developed FO.

本研究解决了考虑公平性和可访问性的医疗机构位置/网络设计问题。定位医疗设施、规划医疗设施的容量和设计传输网络是给定问题的主要目标。所提出的模型旨在最小化系统成本，最大化可达性，并最小化所有需求节点之间的不平等。提出了一个真实世界的案例研究，以阐明所提出模型的性能和适用性。此外，还提出了一种修复和优化 (FO) 方法来大规模解决该问题。从几个测试问题的实验中获得的结果表明开发的 FO 的效率。
