Constant Failure Rate λ and the Exponential Life Model
When the hazard rate is flat, R(t) = e^{-λt} and the algebra of reliability becomes additive in λ. This assumption is what makes parts-count prediction, series-system multiplication and MTBF arithmetic possible — and its limits are what physics-of-failure exists to expose. The model has to be understood before its misuse can be judged.
