Location cover models are aimed at siting facilities so as to provide service to demand efficiently. These models are crucial in the management, planning and decision-making of service systems in public and private sectors. As a result, location cover models have been incorporated in a range of GIS tools, either closed or open source. Among them, open-source tools are advantageous due to transparency and reproducibility. Nonetheless, the capabilities and limitations of location cover tools remain largely unknown, necessitating further investigation and assessment. To this end, this paper provides an overview of the open-source tools that are capable of structuring and solving location cover models. Case studies are provided to demonstrate access of location models through different open-source tools as well as exploring solution quality, scalability, computing performance and reproducibility. Directions for improving location cover models accessible through open-source tools are summarized based on this review.

位置覆盖模型针对选址设施，以便有效地提供需求服务。这些模型对于公共和私营部门的服务系统的管理，规划和决策至关重要。结果，位置覆盖模型已被纳入到封闭或开放源代码的一系列GIS工具中。其中，由于透明性和可重复性，开源工具是有优势的。尽管如此，位置覆盖工具的功能和局限性仍然未知，因此有必要进行进一步的调查和评估。为此，本文概述了能够构建和求解位置覆盖模型的开源工具。提供了案例研究，以演示通过不同的开源工具访问位置模型以及探索解决方案质量，可扩展性，计算性能和可重复性。在此评论的基础上，总结了改善可通过开源工具访问的位置覆盖模型的方向。
