Abstract

The U.S. Air Force (USAF) estimates it has a $33 billion deferred maintenance backlog within its $263 billion infrastructure portfolio. While the USAF has had recent success advocating for additional funding, new investment and maintenance strategies are ultimately needed to reduce the cost of ownership of its infrastructure while addressing risk and performance-based requirements. This paper documents a simulation-based methodology to implement a portfolio-wide, lowest life-cycle cost strategy projected to provide a $126 million annualized savings. The RAMPSS algorithm developed through this research provides a strategic, decision-making support tool to help reverse the growing maintenance backlog. Analysis from RAMPSS of the USAF’s pavement portfolio suggests that airfields are generally more cost-effective to maintain if kept in better conditions with strategies other than localized preventative maintenance.

基于模拟的个性化机场路面维护建议,以降低美国空军的总拥有成本

摘要

美国空军 (USAF) 估计其 2630 亿美元的基础设施组合中有 330 亿美元的延期维护积压。虽然美国空军最近在倡导额外资金方面取得了成功,但最终需要新的投资和维护战略来降低其基础设施的拥有成本,同时满足风险和基于性能的要求。本文记录了一种基于模拟的方法,用于实施整个投资组合的最低生命周期成本战略,预计每年可节省 1.26 亿美元。通过这项研究开发的 RAMPSS 算法提供了一种战略性的决策支持工具,以帮助扭转不断增长的维护积压。
