Quantification of Logistics Capabilities

Abstract

The objectives of this project were to investigate the relationship between personnel skill level and mission capability (MC) and to develop an associated metric and standard. Specifically, the authors sought to develop a metric that measures MC rate as a function of maintenance (MX) personnel skill levels. Once the metric is determined, they identify a standard for the metric that sets the metric value that the Air Force should strive to maintain as part of their operational goals. The relationships between MX personnel skill level and multiple utilization and reliability and maintainability performance measures also are examined. The research methodology consisted of performing four analysis tasks for each dependent variable. The first task was to define how the variables would be used in the analysis. The authors identified 10 independent variables measuring MX personnel skill level, including the count and percentage of 3-, 5-, 7-, and 9-Level maintainers. The dependent variables that were modeled included MC rate, four utilization variables, and three reliability and maintainability variables. The second task was to perform a correlation analysis between the dependent and independent variables. Building upon the second task, the third task was to construct a set of candidate regression models for each of the dependent variables. The last task was to choose a final model for each dependent variable by examining the linear fit of the models, their efficiency, and their adherence to model assumptions. During this analysis and selection process, it was determined that good regression models for flying hours and sorties (two of the utilization variables) could not be developed as a function of MX personnel skill level variables.
