Jaret Matthews AAE 450 Team A Cost & Risk Assessment Jaret Matthews AAE 450 Team A
Project Goals & Redundancy Minimize Cost 95% Probability of safe return of the crew 80% Probability of mission success Life critical = 3 levels of redundancy Mission critical = 2 levels of redundancy
Cost Analysis Spacecraft/Vehicle Level Cost Model Top level model derived from NAFCOM Contacting Science Applications International Corporation – NAFCOM 96 Development, production, and operations cost modeling of aerospace projects
Risk Assessment Probabilistic Risk Assessment (PRA) Comprehensive systems analysis that quantitatively expresses risk of failure Can be recalculated throughout development and influence design
Probabilistic Risk Assessment Solar panels function normally Batteries are charged Fuel cells are OK End States S= Success F=Failure Micro- meteorite impacts solar panels S=.80 .80 S=.12 .20 S= 95% .60 S=.028 .40 .35 F= 5% F=.052 .65
Probabilistic Risk Assessment End States S= Success F=Failure Tire stays inflated Spare is OK Jack is OK Tires roll over road hazard S=.05 .05 S= 51% S=.456 .95 .80 .60 .40 F=.304 F= 49% .20 F=.19
