An Analytical Model for Predicting the Impact of Maintenance
Resource Allocation on National Airspace System Availability

Myron Hecht, Jady Handal, Frank Demarco, "An Analytical Model for Predicting the Impact of Maintenance Resource Allocation on National Airspace System Availability", National Research Council Transportation Research Board 79th Annual Meeting, Washington, DC, January, 2000

This paper presents an analytical model and software tool that can be used by non-experts to relate FAA maintenance resources including staffing, training, shift allocation, and geographicaldeployment to NAS facility and service downtime and availability. The analytical methodology and tool presented in this paper make it possible for any user to rapidly assess how changes in staffing, training, equipment count, and reliability will impact outage time, availability, maintenance backlog and technician utilization. It allows users to easily perform parametric studies on a variety of "what if" scenarios related to economics and capacity. The most significant benefit is that these results can now be made available to analysts and decision makers. The net result will be more informed decisions that to account for the impact of maintenance resources on NAS capacity and overall economics.
