Distribution Network Design for Syrian Refugees in Kilis Optimising cost and reach: parameters and solutions

These data sets are prepared and used within a humanitarian operations project entitled "Innovating the Turkish supply chain for services in humanitarian aid".
The initial data set includes the GIS coordination and population information of a central depot (Municipality building), 18 potential service points (2 hospitals, 1 Red Crescent office, and 15 schools) together with 187 (109 villages and 78 neighbourhoods) main locations where Syrian refugees inhabit in the Kilis province in southern Turkey. Locations are classified as Villages (Köy) and Neighbourhoods (Mahalle) based on administrative divisions of Turkey. A matrix of pair-wise distances (in Km) among the identified locations is provided accordingly. The population of each identified demand location, which is obtained from the local government in 2018, is provided as well.
Two additional data sets, given in zip files, are representing the supplementary data for an academic paper submitted to EJOR during the above-mentioned project. The first zip file provides parameters and solutions of 505 instances corresponding to different capacity configurations of E-voucher distribution network for Syrian refugees in Kilis. The second zip file, provides some relatively small dummy instances, created from TSPLIB networks, for algorithm evaluation and benchmark purpose. A ‘README’ file is given in each of them explaining the details of parameter files and layout of the data to enable OR practitioners to solve the same instances by alternative approaches for comparison and assessment purposes.

本数据集服务于一项题为“革新土耳其人道主义援助服务供应链”的人道主义行动项目，并在该项目框架内筹备与使用。
初始数据集包含土耳其南部基利斯省一处中央仓储点（市政大楼）的地理信息系统（Geographic Information System, GIS）坐标与人口信息、18个潜在服务点位（含2家医院、1家红新月会办公室及15所学校），以及叙利亚难民主要聚居的187个核心点位（其中109个村庄、78个社区）。所有点位依据土耳其行政区划标准划分为村庄（Köy）与社区（Mahalle）两类。本数据集同时提供了上述所有点位间的两两距离矩阵（单位：千米），以及2018年从当地政府获取的各需求点位人口数据。
另有两个压缩包格式的附加数据集，为本项目相关、已投稿至欧洲运筹学杂志（European Journal of Operational Research, EJOR）的学术论文提供补充数据。第一个压缩包包含针对基利斯省叙利亚难民电子券配送网络的505组不同容量配置场景的参数与求解结果；第二个压缩包则提供了基于旅行商问题库（TSPLIB）网络生成的若干小型虚拟测试实例，用于算法评估与基准测试。两个压缩包均附带README文件，详细说明参数文件格式与数据组织结构，以便运筹学（Operations Research, OR）从业者采用不同方法求解同一测试实例，实现方案的对比与评估。
