Despite the critical role that replication plays in the advancement of science, its presence in modelling literature is rare. To encourage others to conduct replication and report success and challenges that facilitate or hinder replication, we present the replication of an agent-based model (ABM) of residential sprawl using the Replication Standard. Replication results achieved relational equivalence. Through the replication process, issues with the original research were identified and corrected in an Improved model, which qualitatively supported original results. A specific challenge affecting alignment of original and Replicate models included capturing model output variability and publishing all original output data for statistical analysis. Through the replication of agent-based models, additional confidence in model behaviour can be garnered and replicated ABMs can become accredited for reuse by others. Future research in the development and refinement of replication methodology and assessments should be cultivated along with a culture of value for replication efforts.

尽管复制在科学的发展中起着至关重要的作用，但它在建模文献中的存在却很少。为了鼓励其他人进行复制并报告促进或阻碍复制的成功与挑战，我们提出了使用复制标准对住宅蔓延的基于代理模型（ABM）的复制。复制结果实现了关系对等。通过复制过程，可以识别和纠正原始研究的问题，并在改进的模型中进行纠正，从而在质量上支持原始结果。影响原始模型和复制模型对齐的一个具体挑战包括捕获模型输出的可变性并发布所有原始输出数据以进行统计分析。通过复制基于代理的模型，可以提高对模型行为的信心，并且可以认可复制的ABM，以供其他人重复使用。应该在复制方法的开发和完善以及评估的未来研究中，以及对复制努力的价值文化的培育。
