An Evaluation Of Forecasting Methods That Could Be Used In The Brazilian Air Force Uniform Distribution Process, Leandro Valviesse De Oliveira
An Evaluation Of Forecasting Methods That Could Be Used In The Brazilian Air Force Uniform Distribution Process, Leandro Valviesse De Oliveira
Theses and Dissertations
Every year the Brazilian Air Force (BAF) spends the equivalent of approximately 15 million dollars for uniforms. These purchases come from a tight budget, are executed through public procurement processes, and are tied to Brazilian acquisition regulations, which are often very strict. For this reason, lead times are unpredictable. It can take anywhere from one month to a year to replenish an item. The purpose of this research is to analyze the forecasting process performed at a BAF military organization named Sub-directorate of Supply (SDS) with the intent of building an algorithm comprised of a selection of forecasting models in …
Analysis Of The Effect Of Centralizing Management Of Mobility Readiness Spares Package Assets, Ian R. Hester
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 …
The Effect Of Improving The Logistics Pipeline On Supply Support Of Aerospace Expeditionary Forces, Steven L. Martinez
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 …
Effects Of Alternative Performance Criteria Upon Composition Of Air Transportable Spare Parts Kits, Murat V. Buyukacar
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 …
A Statistical Analysis Of The Variability Experienced In Dla Administrative And Production Lead Time, Kieran F. Keelty
A Statistical Analysis Of The Variability Experienced In Dla Administrative And Production Lead Time, Kieran F. Keelty
Theses and Dissertations
This study examined the variability experienced in the administrative and production lead times of consumable items managed by the Defense Logistics Agency (DLA). Assets were categorized based on an item manager's determination that an asset was a problem part, and whether the asset was purchased for stock replenishment or direct vendor delivery. The methodology was a two-sample t-test of aggregated data to determine if significant differences existed between the mean deviations from the system lead times of various combinations of categories. The study produced results indicating that a significant difference did not exist between the mean deviations of problem parts …
Measuring The Effect Of Rfid Technology On Movement Of U.S. Army Resupply Cargo, Leigh E. Method
Measuring The Effect Of Rfid Technology On Movement Of U.S. Army Resupply Cargo, Leigh E. Method
Theses and Dissertations
This research is an analysis of the effect that the added in-transit visibility (ITV) associated with applying Radio Frequency Identification (RFID) technology to Army resupply cargo makes on total cycle time (from entry into to exit from the system) within the Air Mobility Command (AMC) portion of the Defense Transportation System. Although information technology applications are known to contribute to ITV, there has been no attempt to quantify it despite a perception held by at least part of the DoD community that ITV initiatives will reduce logistics response time by improving cycle time. This study was aimed at quantifying RFID …
A Study Of Defense Logistics Agency Inventory Classifications: Application Of Inventory Control Methods To Reduce Total Variable Cost And Stockage Levels, Wayne C. Goulet, Michael L. Rollman
A Study Of Defense Logistics Agency Inventory Classifications: Application Of Inventory Control Methods To Reduce Total Variable Cost And Stockage Levels, Wayne C. Goulet, Michael L. Rollman
Theses and Dissertations
This thesis analyzes the financial impact of applying a single inventory requirements model to three separate classes of inventory at the Defense Logistics Agency's (DLA) Defense Supply Center-Columbus (DSCC) commodity management facility. DLA' 5 blanket application of its variation of the Economic Order Quantity (EOQ) requirements model may not be appropriate for all levels of demand, possibly suboptimizing DLA's desire to minimize inventory costs while still providing an appropriate level of customer service. Simulation analyses of the DLA EOQ requirements model, the Silver-Meal heuristic, and Periodic Order Quantity models were conducted to examine which dynamic lot-sizing model is more effective …
An Evaluation Of The Appropriateness Of The Defense Logistics Agency's Model Requirements Model, Harry A. Berry, Edward E. Tatge
An Evaluation Of The Appropriateness Of The Defense Logistics Agency's Model Requirements Model, Harry A. Berry, Edward E. Tatge
Theses and Dissertations
This thesis discusses the appropriateness of the Defense Logistics Agency's (DLA) requirements model in managing consumable support for Air Force peculiar items. Currently, DLA uses a lot sizing technique referred to as the classic Economic Order Quantity, (EOQ) model. One of the key assumptions of this model is that demand is constant and continuous. Yet with Air Force bases using a lot sizing technique to place their demands for consumable items to DLA, it is apparent that the demand pattern that DLA faces, at least for Air Force peculiar items, is not constant and continuous. This study looks at the …
Pharmaceutical Inventory Forecasting At The Wright-Patterson Medical Center, Patrick J. Reymann
Pharmaceutical Inventory Forecasting At The Wright-Patterson Medical Center, Patrick J. Reymann
Theses and Dissertations
This research was conducted to determine the accuracy of statistical forecasting techniques forecasting the inventory of pharmaceutical items. Because pharmaceutical items are subject to a degree of seasonality of demand, the Director of Medical Logistics at the Wright-Patterson Medical Center believed that the use of such techniques may provide a more accurate forecast for the items stocked by the Outpatient Pharmacy. In addition to the technique used by the Outpatient Pharmacy (the 12 month simple moving average) three statistical forecasting methods were employed: the 6 month simple moving average, simple exponential smoothing, and the Winter's exponential smoothing. These techniques were …
