The aim of this research work is to develop a framework for making coordinated acquisitions decisions, integrating i schedules of maintenance based on the condition of system components, and ii trigger acquisition of multiple vendor maintenance, repair, and overhaul MRO supplies and services. To do so, we develop a multi-objective optimization maintenanceacquisition scheduling algorithm where tradeoffs are made between two competing objectives maximizing condition-based component reliability while maximizing the sensitivity of condition-based reliability to changes in the component s condition e.g., degradation. This scheduling algorithm integrates with an acquisition algorithm to addresses vendor lead-time. Case studies broadly inspired by Tinker Air Force Base, the largest Air Force MRO hub in the US, in Oklahoma City, OK, illustrate the framework.
