Given the importance of maintaining infrastructure assets, asset management at both project- and network-levels has been the focus of hundreds of studies. Although these studies and previously developed asset management systems have pushed the boundaries of this field, these advances have been made separately without the ability to build upon one another. This paper puts forward the first open-source, extensible, freely accessible, and modular platform developed in Python, GIAMS, paving the way for researchers and practitioners to easily collaborate and contribute to future related research. Drawing upon related literature, this paper describes modules of GIAMS and illustrates their use with bridge components and models. One project-level lifecycle optimization and one network-level project-selection based on the Indiana, US, bridge network with more than 4600 bridges are provided to demonstrate the applicability of GIAMS. The modular and open-source nature of GIAMS makes it readily capable of further extension in a variety of asset management topics.

考虑到维护基础架构资产的重要性，在项目和网络级别的资产管理已成为数百项研究的重点。尽管这些研究和先前开发的资产管理系统已经突破了这一领域的界限，但是这些进步是在没有彼此依靠的情况下单独取得的。本文提出了第一个使用Python，GIAMS开发的开源，可扩展，可自由访问的模块化平台，为研究人员和从业人员轻松协作并为未来的相关研究做出贡献铺平了道路。借鉴相关文献，本文描述了GIAMS的模块，并说明了它们在桥梁组件和模型中的使用。基于美国印第安纳州的一项项目级生命周期优化和一项网络级项目选择，提供了具有4600多个网桥的网桥网络，以演示GIAMS的适用性。GIAMS的模块化和开放源代码性质使其能够轻松地在各种资产管理主题中进一步扩展。
