Aligning Performance Management Systems For Lasting Outcomes In Humanitarian Operations, Kalyn M. Howard
Aligning Performance Management Systems For Lasting Outcomes In Humanitarian Operations, Kalyn M. Howard
Theses and Dissertations
Logistics is dynamic, expansive, and critical to organizational success. While it is generally believed that effective logistics management is associated with positive performance outcomes, the links between organizational practice and performance are understudied. This dissertation leverages resource-based theory and organizational learning theory to examine organizational practice and performance in non-traditional logistics settings, with particular focus on military organizations and humanitarian operational settings. First, a meta-analytical study establishes generalizable associations between various operations management practices and performance outcomes. Then, this is applied to dynamic humanitarian logistics settings, exploring how practitioners perceive practice and performance, and how this is reported and documented …
Simulation Modeling And Analysis Of Air Force Depot Engine Repair During Normal And Increased Operational Tempos, Changsung Kim
Simulation Modeling And Analysis Of Air Force Depot Engine Repair During Normal And Increased Operational Tempos, Changsung Kim
Theses and Dissertations
Maintaining an adequate level of aircraft availability through Agile Combat Support (ACS) is crucial for the Air Force to perform its mission. During normal day to day operations, demands for depot repair including spare parts and maintenance man-hours typically fall within a range supportable with current assets and capabilities. However, with increased flying operations during a conflict, demand at the depot level may likely exceed current capacity for timely support, resulting in backorders for spares and increased turnaround times. This thesis develops a discrete event simulation of the F-16 engine repair network to investigate the impact on engine availability (a …
The Viability Of The Air Mobility Command Pure Pallet Program For Us Army Reparable Retrograde Shipments, William L. Jackson Jr.
The Viability Of The Air Mobility Command Pure Pallet Program For Us Army Reparable Retrograde Shipments, William L. Jackson Jr.
Theses and Dissertations
Last year, Congress approved $17.1 billion dollars, an increase of $4 billion dollars more than originally was requested by the Bush Administration, for US Army vehicles to be repaired or replaced (commonly referred to as reset) as a result of military operations in Iraq and Afghanistan. A large portion of the repair workload falls upon the Army depots in Anniston and Red River in Texarkana, Texas and must rely on the DOD transportation system for air and surface movement of retrograde cargo deemed serviceable and unserviceable to fill requisitions and backorders for entry into the national supply inventory. Headquarters Air …
A Group Theoretic Tabu Search Methodology For Solving The Theater Distribution Vehicle Routing And Scheduling Problem, John R. Crino
A Group Theoretic Tabu Search Methodology For Solving The Theater Distribution Vehicle Routing And Scheduling Problem, John R. Crino
Theses and Dissertations
The application of Group Theory to Tabu Search is a new and exciting field of research. This dissertation applies and extends some of Colletti's (1999) seminal work in group theory and metaheuristics in order to solve the theater distribution vehicle routing and scheduling problem (TDVRSP). This research produced a robust, efficient, effective and flexible generalized theater distribution model that prescribes the routing and scheduling of multi-modal theater transportation assets to provide economically efficient time definite delivery of cargo to customers. In doing so, advances are provided in the field of group theoretic tabu search and its application to difficult combinatorial …
A Large Scale Integer Linear Program As A Decision Support Tool For Force Mix Selection, Craig A. Punches
A Large Scale Integer Linear Program As A Decision Support Tool For Force Mix Selection, Craig A. Punches
Theses and Dissertations
Recently, organizations have been modifying performance appraisal systems to collect data from multiple sources to guide the development of supervisors. Upward feedback programs focus on development rather than appraisal by supplementing traditional downward feedback with subordinate feedback. The upward feedback instrument developed in this study was designed to measure effective leadership behaviors utilizing an existing five-dimension leadership taxonomy and a new dimension that represents creating a fun workplace. The developed instrument and a proven commercial instrument utilizing the same theoretical framework were administered to samples of N = 391 and N = 417 respectively, and tested for reliability and validity. …
Interim Brigade Combat Team (Ibct) Munitions Distribution Study, Todd S. Bertulis
Interim Brigade Combat Team (Ibct) Munitions Distribution Study, Todd S. Bertulis
Theses and Dissertations
This research sought to describe an alternative way for calculating expected back order (EBO) for reparable inventory systems. The high costs associated with reparable items management, together with its importance for system's availability, make the assessment of back orders of great importance in supporting decisions of what-to-buy and where-to-locate those items. Starting at the point that existing models (METRIC, MOD-METRIC, and VARIMETRIC) rely on some assumptions that often cannot be met in real life, the proposed method (called P-METRIC), which is a mix of simulation and mathematical analytical model, relaxes assumptions about Demand, Time to Repair (TTR), and Ordering & …
Improving Performance Analysis Of The Distribution Segment Of The Air Force Logistics Pipeline, Heinz H. Huester
Improving Performance Analysis Of The Distribution Segment Of The Air Force Logistics Pipeline, Heinz H. Huester
Theses and Dissertations
The Army of the future will need to be able to quickly respond to a full spectrum of conflict-from stability and support operations to major theater wars. Today, military leaders have limited options when reacting to the wide range of current threats existing in our world. The nation needs ground combat units that can deploy very rapidly to stabilize a hostile area while possessing combat capabilities able to terminate a threat if necessary. The Army's answer to this requirement is the Interim Brigade Combat Team (IBCT). This study employs an Arena 5.0 discrete-event simulation model to explore the capabilities of …
Logistics Transformation: Centralizing Air Force Logistics Information Command And Control, Darrell O. Burghard
Logistics Transformation: Centralizing Air Force Logistics Information Command And Control, Darrell O. Burghard
Theses and Dissertations
Current Air Force logistics information systems do not provide Air Force leaders and single managers a real-time sole-source logistics information system able to assess current capabilities and identify potential future problem items prior to becoming systemic problem parts. Centralizing information may provide improved command and control and support of the warfighter by reducing the time it takes to track down and identify information. Using a Value Focused Thinking approach, this thesis explored how the Air Force can improve the accessibility of Air Force logistics information. This study began at the behest of the AFMC LG/CD in an effort to determine …
A Combined Inventory And Delivery Model For Repairable Items, Bahtiyar Eren
A Combined Inventory And Delivery Model For Repairable Items, Bahtiyar Eren
Theses and Dissertations
Traditionally, logistics analysts have treated the delivery problem separate from the inventory and repair problems. In other words, each of these three problems-delivery, inventory, and repair-are treated individually. We combine the vehicle routing problems and inventory allocation problems in a single formulation. Furthermore, lateral re-supply is considered, in that supplies are not only available from the main depot, but also from other bases. After we get the lateral re-supply information, we set a delivery allocation plan out of the main depot. Such allocations are then delivered via vehicles stationed at the main depot. There is a repair capability for each …
A Model To Forecast Civilian Personnel Inventory For The National Security Agency, Stephen G. Hoffman
A Model To Forecast Civilian Personnel Inventory For The National Security Agency, Stephen G. Hoffman
Theses and Dissertations
The purpose of this thesis is to develop a model to forecast civilian personnel inventory for the National Security Agency (NSA). Accurate prediction of personnel inventories will help the NSA with issues ranging from hiring, promotion, and ethnic/gender diversity to the development of cost-effective force reduction programs. The model must be capable of producing multiple-year forecasts of the NSA's civilian force structure with a minimum fidelity level that allows for break-out by years-of-service, career field, and grade. Historical data will be utilized to estimate logistic regression parameters that will compose the internal workings of the model. The JMP statistical software …
Strategic Performance Measurement In An Air Force Logistics Organization, Michael A. Grover
Strategic Performance Measurement In An Air Force Logistics Organization, Michael A. Grover
Theses and Dissertations
Strategic performance measures are being used to define and communicate longer term planning imperatives to organizational members and external stakeholders. These measures are designed to support the concept of a strategic management process, in which the progress towards strategic goals, and also the goals are continuously reviewed and updated. The measures are linked through associations and communicate the strategy as a series of hypothesized cause and effect relationships. One such performance measurement system, the balanced scorecard, describes the organizational strategy with reference to four common organizational perspectives: Financial, Customer, Internal Process and Growth and Development. A case study is performed …

Development Of The Base Support Plan Process Model For Evaluation Of Proposed Process Improvement Initiatives, Daniel T. Kalosky, Patrick G. Walker
Theses and Dissertations
The primary role of the United States Air Force (USAF) logistics planner is to plan for war. For the wing level logistics planner, an important war planning product they are responsible for is the base support plan (BSP). The BSP is the installation level plan to support unified and specified command wartime operations plans, as well as MAJCOM supporting plans. Two Armstrong Laboratory sponsored initiatives exist to automate and enhance some of the BSP processes: the Survey Tool for Employment Planning (STEP) and Beddown Capability and Assessment Tool (BCAT). This research explored the BSP process and improvement initiatives by (1) …

Logistics Control Facility: A Normative Model For Total Asset Visibility In The Air Force Logistics System, Eric C. Lorraine, Michael E. Michno
Theses and Dissertations
Computer simulation was used to evaluate the impact of a Logistics Control Facility LCF with a Total Asset Visibility TAV system on the AF logistics systems ability to support a weapon system. For this study, the B-1B was chosen as the weapon system of interest. Two performance measures, expected fully mission capable rates and expected pipeline quantities, were used to evaluate the simulation results. Two-sample tests were used to compare the current logistics configuration of the B-1B with the same configuration, but with an LCF controlling the movement of assets. The expected FMC rate performance measure showed significant results while …
