Comparison of case studies regarding approach and benefits

FUPBM stepsCase 1 – combat vehicleCase 2 – naval radarCase 3 – helicopter
1. MonitoringUser registration of mission types and durationUser registration of mission types/phases and durationUser registration of saline flight hours (FHs)
2. Usage profilesHigh level: mission types
Lower level: surface type and terrain roughness
High level: mission types Lower level: vibrations, temp. changesHigh level: fraction saline FHs
3. Quantifying severitiesA. Component level
B. Expert Opinion
A. Component level
