An Adaptive Tabu Search Heuristic For The Location Routing Pickup And Delivery Problem With Time Windows With A Theater Distribution Application, Robert E. Burks Jr.
An Adaptive Tabu Search Heuristic For The Location Routing Pickup And Delivery Problem With Time Windows With A Theater Distribution Application, Robert E. Burks Jr.
Theses and Dissertations
The time constrained pickup and delivery problem (PDPTW) is a problem of finding a set of routes for a fleet of vehicles in order to satisfy a set of transportation requests. Each request represents a user-specified pickup and delivery location. The PDPTW may be used to model many problems in logistics and public transportation. The location routing problem (LRP) is an extension of the vehicle routing problem where the solution identifies the optimal location of the depots and provides the vehicle schedules and distribution routes. This dissertation seeks to blend the PDPTW and LRP areas of research and formulate a …
Modeling A Reparable Supply Chain And Applying Cpfr Concepts, Sandra A. Mayhall
Modeling A Reparable Supply Chain And Applying Cpfr Concepts, Sandra A. Mayhall
Theses and Dissertations
The Air Force supply chain includes parts required to build, fix, or maintain aircraft delivered to the warfighter to carry out missions. Industry has shown that following Collaborative Planning, Forecasting, and Replenishment (CPFR) concepts, particularly reducing inventory through accurate demand forecasts, has increased profits in part by lowering the holding costs of inventory and increasing sales. This is analogous to the Air Force increasing aircraft availability. There is scant evidence that demand forecasts generated at any level in the Air Force are shared with the intent of coordinating replenishment. This thesis uses a simple discrete-event stochastic simulation model to show …
Reducing Uncertainty In Effects-Based Operations, Wilburn B. Mclamb
Reducing Uncertainty In Effects-Based Operations, Wilburn B. Mclamb
Theses and Dissertations
Known as the fog of war, uncertainty has been prevalent in the conduct of military operations throughout human history. Intelligence collection efforts are tasked to reduce this uncertainty through the collection of information. Utilizing Shannon's entropy as a measure of the expected information gain due to an intelligence collection effort, a methodology is developed to prioritize and allocate intelligence assets in an efficient manner. Incorporated in this methodology are target priority and the requirement to reassess dynamic targets. The application area for the methodology is Effects-Based Operations. A generalized state model is developed to conduct adversary system-of-systems analysis. This model …
Understanding Innovation Adoption In The Air Force, Morgan J. Evans
Understanding Innovation Adoption In The Air Force, Morgan J. Evans
Theses and Dissertations
Innovation adoption has become a critical issue for organizations in both the public and private sectors. The search for competitive advantage has led to the recognition that innovation is a vital ingredient for an organization's survival and profitability in this information age. The United States Air Force is seeking to adapt to this new information age by transforming its business processes in order to sustain its competitive advantage as the world's most respected air force. Adopting innovations and integrating new or improved technologies, capabilities, concepts, and processes into Air Force planning and acquisition activities, organizations, and operations are goals of …
