Spares Strategy for Programs in Development Phases: Quantifying Hardware Needs Prior to Production

Verification and Validation;Integration and Test;Development;Systems Engineering;Spares;Project Management

Sparing strategies are widely employed for systems in production or operation where the system has completed development/certification and has a statistically significant set of failure data. However, there is no quantitative approach for a sparing strategy supporting a program in development phases. This research proposes a modified set of equations for calculating ‘Cost VS Risk of Failure’ and a process to create a quantitative sparing strategy for a system in the development phase.
