An Integrated Asset Management System (IAMS) is a strategic asset management system that combines the assets of different categories into a system to prioritize their maintenance. This paper proposes a risk-based reliability-centric IAMS framework which works on the principle that the risk associated with the failure of an asset is a function of its direct and indirect costs. The direct costs are the costs associated with the replacement of the assets, whereas the indirect costs are the risks that the city faces following the failure. The framework is applied to the asset database of the City of Sugar Land, TX. The results of the model are analyzed in terms of a reduction in the number of assets in a very high-risk category in the risk matrix, the network level expected annual failure rate, and an increase in the network level average reliability.

综合资产管理系统（IAMS）是一种战略资产管理系统，它将不同类别的资产组合成一个系统，以确定其维护的优先级。本文提出了一个基于风险的以可靠性为中心的 IAMS 框架，其工作原理是与资产故障相关的风险是其直接和间接成本的函数。直接成本是与资产置换相关的成本，而间接成本是城市在失败后面临的风险。该框架应用于德克萨斯州舒格兰市的资产数据库。模型结果从风险矩阵中极高风险类别资产数量的减少、网络级预期年故障率、网络级平均可靠性的提高等方面进行分析。
