Statistical Analysis of Environmental Effects on Reliability Decay of Missiles: A Case Study

Abstract

Generalized linear models are used to predict the deterioration pattern for missiles stored in four different environmental conditions. The rate of deterioration over time is assumed to be non-negative, and it is estimated from repeated measurement of the binary responses from a series of intermittent flight tests. Results of the statistical tests indicate that environmental effects are not significant on missile decay. Additionally, the estimation method for the missile shelf-life is suggested.
