STATISTICAL-ANALYSIS OF ENVIRONMENTAL-EFFECTS ON RELIABILITY DECAY OFMISSILES - A CASE-STUDY

Generalized linear models are used to predict the deterioration patter n 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 dec ay. Additionally, the estimation method for the missile shelf-life is suggested.
