The primary objectives of this project were (1) identify the relationships among manpower, personnel, and training (MPT) factors considered during system acquisition as they impact maintenance performance; (2) organize the MPT factors; (3) determine quantitative relationships among the factors; (4) express the factors in terms of a common metric; and (5) develop a trade-off tool for examining the impact on maintenance of the identified factors based on the factor relationships. Eight models containing MPT factors that might impact maintenance performance were examined to determine the relationships among the models and their contained factors. Elemental factors from seven of the models were identified as representing metafactors found in the eighth model. Elemental factors representing a subset of the metafactors were selected for inclusion in a set of multiple regression analyses in which these factors predicted times to perform maintenance tasks. This resulted in weights for the elemental factors and the metafactors. A common metric for the weights was developed, and a trade- off tool was developed based on the performed analyses. Researchers found that the developed multiple regression equations accounted for a wide range of variance, depending on the dependent measure under examination. |
