Spare availability assessment is an important part of support ability assessment. This paper gives mathematical spare availability models for spare components with exponential, normal, Weibull and time to failure distribution. Three application examples are presented to verify the models. An optimization model of the spare components is also provided. This optimization model can be used to predict the number of spares required for a system to achieve specified spare availability.
