A series of mathematical models of the influence of environmental effects on maintenance costs was constructed using linear regression analysis. The equipment whose behavior were modeled were the KC-135 Doppler Radar and the F-4E engine starter. Models explaining more than 20 of the variation in maintenance cost as a result of weather factors were developed, where only the two most current months weather was considered. Recommendations for further research using more sophisticated model development techniques are presented. A limited economic analysis of some life cycle cost implications of failure countermeasures for increased environmental resistance is given.
