Integration Of The Distribution And Repair In Variable Environments (Drive) Model Into Micap Policy, Bradley E. Anderson
Integration Of The Distribution And Repair In Variable Environments (Drive) Model Into Micap Policy, Bradley E. Anderson
Theses and Dissertations
The United States Air Force has implemented the Distribution and Repair In Variable Environments (DRIVE) Model to a limited degree for a limited range of items, and policy makers seem unsure as to the proper level of DRIVE utilization. New asset release sequences and policies have been proposed without evidence to support those decisions. The purpose of this study is to explore different levels of DRIVE implementation relating to proposed asset release policies in order to provide some evidence on which policy could best support Air Force weapon systems. A second purpose of this study is to show how the …
Modeling Diminishing Marginal Returns: An Application To The Aircraft Availability Model, Wayne L. Zorn
Modeling Diminishing Marginal Returns: An Application To The Aircraft Availability Model, Wayne L. Zorn
Theses and Dissertations
The Aircraft Availability Model (AAM) provides the Air Force with a worldwide peacetime requirement for reparable spare parts. This research models AAM methodology as it relates to the concept of diminishing marginal returns in resource application. Three separate modeling techniques are investigated with the goal of reformulating the AAM as a mathematical programming model that provides a comparable solution and a capable tool for the conduct of sensitivity analysis. The general formulations presented here are continuous non-linear, continuous linear, and piecewise linear discrete/continuous models. Two formulations of the piecewise linear discrete/continuous model are presented. The piecewise linear model based on …
