Integer Approximation Of Real Valued Preference Curves, Richard M. Antoine May 2001

Integer Approximation Of Real Valued Preference Curves, Richard M. Antoine

Theses and Dissertations

A primary challenge of the AFIT Mission Resource Value Assessment Tool is to approximate a given preference curve with integer valued mission ready resources. This thesis evaluated four candidate methods of accomplishing this approximation. The thesis evaluated the implementation of the integer estimation approximation from a purely mathematical perspective. The models were measured against six quality and error measurement standards: convergence on an endpoint, convergence on any interior integer points, characterization of the overall error between the sequence of integer coordinates and the real valued linear function and characterization of the error in each individual dimension of the problem space. …

Jp-8+100lt: A Low Cost Replacement Of Jpts As The Primary Fuel For The U-2 Aircraft, Christian G. Simms Mar 2001

Jp-8+100lt: A Low Cost Replacement Of Jpts As The Primary Fuel For The U-2 Aircraft, Christian G. Simms

Theses and Dissertations

The Air Force currently spends approximately $ 10 million dollars annually on fuel support for the U-2 aircraft. The U-2 has used a jet fuel known as JPTS since the aircraft's development in the 1950's. JPTS is a specialty fuel used only by the U-2 and is produced by two oil refineries in the United States. As such, it has limited worldwide availability and costs over three times the per-gallon price of the Air Force's primary jet fuel, JP-8. Recent research performed at the Air Force Research Laboratory Propulsion Directorate suggests that additives could be added to JP-8, which would …

Forecasting Readiness: Using Regression To Predict The Mission Capability Of Air Force F-16 Fighter Aircraft, Steven A. Oliver Mar 2001

Forecasting Readiness: Using Regression To Predict The Mission Capability Of Air Force F-16 Fighter Aircraft, Steven A. Oliver

Theses and Dissertations

According to many, the readiness of America's forces deteriorated in the 1990s. In the Air Force, the combat readiness of its fighter aircraft has declined. One of its indicators of combat readiness, the mission capable rate, is used to identify the percentage of aircraft unable to perform their missions. From FY94-FY98, the aggregate total not mission capable rate for maintenance steadily increased from 14% to 18.2% while total not mission capable rate for supply increased from 5.5% to 17.5% between FY86 and FY00. The USAF uses the funding/Availability Multi-Method Allocator for Spares model to forecast these rates for its aircraft. …

Analysis Of The Effect Of Centralizing Management Of Mobility Readiness Spares Package Assets, Ian R. Hester Mar 2001

Analysis Of The Effect Of Centralizing Management Of Mobility Readiness Spares Package Assets, Ian R. Hester

Theses and Dissertations

Air Force supply doctrine requires the management of large numbers of spare parts in Mobility Readiness Spares Packages (MRSPs). The MRSPs are designed to support deployed aircraft for the first 30 days of a conflict, and can be quite large. When units from several bases deploy to the same operating location, they each bring their full MRSP. This results in a large logistics footprint that may be reduced by taking a system-level approach. This thesis examined the impact of centralized MRSP management on kit size and cost. The Aircraft Sustainability Model (ASM) computer program was used to evaluate MRSPs for …

Dollarizing Qualitative Discriminators Used In Best Value Source Selections, Jason R. Borchers Mar 2001

Dollarizing Qualitative Discriminators Used In Best Value Source Selections, Jason R. Borchers

Theses and Dissertations

With the decreasing budget that gets allocated to the Department of Defense each year, the government needs to be able to acquire more with less. This has a direct impact on how source selections are conducted. This research proposes a method using four different levels of cost that will provide the government with the best overall value in the conduction of source selections. This differs from previous source selections, because source selection teams, in general, only considered proposal price in their evaluation.

Effects Of Alternative Performance Criteria Upon Composition Of Air Transportable Spare Parts Kits, Murat V. Buyukacar Mar 2001

Effects Of Alternative Performance Criteria Upon Composition Of Air Transportable Spare Parts Kits, Murat V. Buyukacar

Theses and Dissertations

Airlift capacity is a definitive factor in the success of large-scale military operations. History proves that the demand for airlift soon exceeds its capacity during simultaneous deployment of forces. Therefore good solutions to the airlift capacity problem are important. This thesis contributes to the resolution of this problem by seeking ways to reduce readiness spare parts packages (RSPs) deployed for Air Force squadrons through addition of airlift criteria into the RSP selection process. We find that item cost, weight, and volume are three important criteria for RSP computations. We then offer a method for implementing these three criteria in the …

The Effect Of Improving The Logistics Pipeline On Supply Support Of Aerospace Expeditionary Forces, Steven L. Martinez Mar 2001

The Effect Of Improving The Logistics Pipeline On Supply Support Of Aerospace Expeditionary Forces, Steven L. Martinez

Theses and Dissertations

One of the biggest considerations for an Aerospace Expeditionary Force (AEF), in terms of cost and airlift requirement, is the use of aircraft spares kits to support combat operations. To date, these kits are built on the assumption that there would be no resupply for the first 30 days of a contingency. However, with more efficient transportation and information resources available today, it seems logical that resupply would occur much more quickly. If so, the Air Force should be able to trim its wartime stocks of aircraft spares. This thesis investigated the effect of improving the logistics pipeline on the …

A Method For Fms Countries To Maximize Clssa Service Levels While Minimizing Costs Through Optimal Requisitioning Patterns, Robert A. Wasik Mar 2001

A Method For Fms Countries To Maximize Clssa Service Levels While Minimizing Costs Through Optimal Requisitioning Patterns, Robert A. Wasik

Theses and Dissertations

The Cooperative Logistics Supply Support Arrangement (CLSSA) is a program designed to provide follow-on supply support for weapon systems procured by foreign military sales (FMS) countries from the United States. CLSSA calculates a Stock Level Quantity (SLQ) for each item based on demand history, item lead-time, and requisitioning patterns. Item SLQs affects program cost and service levels to FMS customers; a high SLQ level improves service levels, but also creates higher costs. The author created a model to replicate the CLSSA formulation used to calculate SLQs, using different Combinations of demand levels and item lead-times to determine the impact that …

A Quantitative Decision Support Model To Aid Selection Of Combat Aircraft Force Mixes For Contingency Deployment, Paul G. Filcek Mar 2001

A Quantitative Decision Support Model To Aid Selection Of Combat Aircraft Force Mixes For Contingency Deployment, Paul G. Filcek

Theses and Dissertations

Selection of combat aircraft during crisis action planning can be of critical importance. In determining the value of force mixes, it is proposed that one can evaluate extrinsic and intrinsic value separately. Intrinsic value is the designed capability of a weapons platform to accomplish a specified aerospace mission. Extrinsic value is the expected appropriateness of such platforms, given the environmental characteristics in which they must operate. This research develops a decision support tool for planners in determining the extrinsic value of force mixes, which then expedites the selection of best overall force mixes. The research included: content analysis of official …
