1	A descriptive analysis of first term attrition from U.S. Naval ships Carlson, Carl Glynn 09 1900 (has links) Approved for public release; distribution is unlimited / This thesis was conducted to analyze certain factors affecting first-term attrition from U.S. Naval ships. The Survival Tracking File (STF) was used as the primary data source, and from it files were constructed that permitted three areas of study. First, the overall cohort of a year's worth of enlistees was examined. The survival curve for the cohort was generated and individual monthly cohorts were examined for attrition patterns. Secondly, overall attrition percentages were calculated for individual ships and for classes of ships and these attrition percentages were then examined for differences using statistical techniques. An ANOVA model using transformed data proved accurate in explaining attrition variance. Lastly, a comparison between attrition per month and underway hours per month was made for classes of ships and for individual ships of three specific classes. A rough relationship was observed, between peaks of high underway hours and peaks of attrition. In looking at individual aircraft carriers, the attrition percentage seemed to be inversely proportional to underway hours per month. Several of these findings warrant further investigation so that the Navy may more fully understand its attrition problem and thereby take steps to alleviate it. / http://archive.org/details/descriptiveanaly00carl / Lieutenant, United States Navy Navy enlisted personnel Navy enlisted attrition Screening selection Attrition Enlisted personnel Ship unique variables Shipboard attrition Ship class attrition Survival track file At sea attrition Ship underway hours history Ship class underway hours history
2	Analysis of high-speed vessels for Seventh Fleet logistics support Morgan, Eric A. 03 1900 (has links) Approved for public release, distribution is unlimited / Commander, Logistics Group, Western Pacific (COMLOGWESTPAC) is concerned with the delivery of high priority material, ordnance, and passengers to U.S. Navy ships due to a very large operations area and limited Combat Logistics Force (CLF) assets. High-speed vessels (HSVs) may have the potential to improve the delivery of these materials when used to complement existing logistics shuttle ships. This thesis quantifies current levels of traditional naval logistics support and provides comparison to HSV-based alternatives in various scenarios. The CLF Scenario Analysis Tool (CLFSAT), a newly developed discrete event simulation model of naval logistics support, performs the analysis. Given a scenario depicting combatant movements and operations, CLFSAT provides insight into the comparative performance of different supporting naval logistics force structures. This analysis determines that HSVs can be effective logistics platforms in specific scenarios when distributing high priority material, ordnance, and stores. HSVs are very effective in small theaters with short transit distances, but for larger theaters, their effectiveness is inversely proportional to distance from the Forward Logistics Site. Regardless of theater size, HSVs show significant improvements in theater distribution of "low density, high priority" cargo, such as precision guided munitions (PGMs) or critical repair parts when customers are outside COD range. / Lieutenant Commander, United States Navy Logistics, Naval Naval auxiliary vessels United States Space shuttles Speed Global sea route Combat logistics force CLF Station ship Shuttle ship Logistics planning factors Safety stocks Underway replenishment UNREP Consolidation CONSOL Inport replenishment INREP High-speed vessel HSV Precision guided munitions PGM Casualty report CASREP High priority material Simkit Java
3	Optimizing global Combat Logistics Force support for sea base operations DeGrange, Walter C. 03 1900 (has links) Approved for public release, distribution is unlimited / The Navy has to choose the number of, and designs for, ships in the Combat Logistics Force (CLF), and then plan how to use them to provide logistical support to our Carrier Strike Groups, Expeditionary Strike Groups, and Seabasing platforms engaged in any variety of worldwide conflicts. CLF ships are very expensive to build and equip and our budget is limited --- we need to make sure the ships we buy and the way we integrate these with our CLF fleet can continue to provide the flexible support our Navy requires. We introduce a decision support tool using a global sea route and resupply base model, and a daily time resolution optimization of CLF ship activities to support any complete, worldwide scenario. Our result is an optimal, face-valid daily operational logistics plan - a schedule of evolutions for each available CLF ship. We discover exactly how to use CLF ships to support a notional, but particularly relevant, preemptive combat scenario with follow-on humanitarian assistance missions. Finally, we study how changing CLF ship numbers and missions can enhance operational effectiveness. / Lieutenant Commander, United States Navy Integer programming Logistics, Naval Decision support systems Humanitarian assistance Optimization Mixed integer program Global sea route Combat logistics force T-AKE T-ADE(X) Station ship Shuttle ship Logistics planning factors Safety stocks Underway replenishment Consolidation Cycle Humanitarian assistance Sea base
