Simulation-based design of aircraft maintenance policies A Simulation Model for Military Aircraft Maintenance in an Uncertain Operational Environment Keywords: discrete-event simulation modeling of uncertainty, risk analysis system reliability and availability maintenance design and optimization

Aircraft availability Reliability of equipment Deterioration Preventive measures Maintenance resources operating policies environment Damages encounters with hostiles opponent’s performance mission success Use of aircraft modes of flying sortie generation rules S ystems Analysis Laboratory Helsinki University of Technology 2

Earlier research Aircraft maintenance and availability Few studies consider uncertain environment (crisis situations) Sensitive nature of initial data Scheduling and inventory problems Simulation, optimization Maintenance optimization models Specific problems Various modeling approaches

Results A simulation model of three air bases Describes operations under state of emergency Based on actual data and expert opinion of FAF Validation through series of revisions Being used by FAF Results of example crisis scenario Aircraft availability and sortie generation capability under varying operating strategies

Reporting Emphasis Publications Modeling with scarce data Aspects of validation under substantial uncertainty A model of an actual system being actually used Publications European Journal of Operational Research IEEE Transactions on Systems, Man and Cybernetics
