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 …

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 Cost Comparison Between Modes In The Shipment Of Mission Capable Parts Within The Continental United States, Jason L. Masciulli Mar 2001

A Cost Comparison Between Modes In The Shipment Of Mission Capable Parts Within The Continental United States, Jason L. Masciulli

Theses and Dissertations

A numerous amount of Mission Capable Parts (MICAPs) are shipped throughout the world by the Air Force. These parts are required in order to meet mission requirements. MICAPs are often shipped via an express, small parcel air carrier, like Federal Express (FedEx). However, there is a lower cost alternative: Less-Than-Truckload express carriers. In using actual Air Force MICAP shipping data, an 11 percent savings was shown if the lowest cost carrier, either FedEx or Roadway Express, an LTL express carrier, was used in shipping these MICAPs. Also, in using simulated shipping data, over 50 percent of all types of shipments, …

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 …

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 …

Tail Docking Dairy Cattle: Effects On Cow Cleanliness And Udder Health, Cassandra B. Tucker, David Fraser, Daniel M. Weary Jan 2001

Tail Docking Dairy Cattle: Effects On Cow Cleanliness And Udder Health, Cassandra B. Tucker, David Fraser, Daniel M. Weary

Farm Animal Husbandry Collection

To determine whether tail docking would influence cow cleanliness and udder health in a free-stall system, we monitored milking cows after half the animals in a herd were docked. A sample of 223 docked and 190 undocked cows (reducing to 169 and 105 over the study as cows were dried off) were monitored for 8 wk. Cow cleanliness was scored in two areas: along the spine, and the rump adjacent to the tail at 1, 2, 3, 5, and 8 wk after docking. Cleanliness was evaluated by counting squares that were soiled (0 to 14 on a 5- × 17.5-cm …
