Mr. Daniel Sillivant

Research Engineer I, Rotorcraft Systems Engineering & Simulation Center (RSESC)


Daniel is a reliability engineer at The University of Alabama in Huntsville. He has worked in reliability engineering for over eight years on various industry, military, and NASA projects. He has developed system level reliability and maintainability models for a global network of systems, to include failure models from based upon OEM, historical, and operator data, reliability block diagrams and simulations for the optimization of system availability and the minimization of cost. He has developed FMEAs (Failure Modes, Effect, and Analysis) on several different systems ranging from electronics to ground vehicles. Other projects include reliability growth, Reliability Centered Maintenance (RCM), Condition Based Maintenance (CBM), and 3-parameter Weibull. He recently began working in System Safety on a NASA project.

His current research interests are developing a system reliability model that utilizes RCM, failure and repair models, maintenance and logistical costs, for the optimization of the life-cycle cost to an organization.
