This book was released on 1999-09-01 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: When attempting to predict the acquisition costs of U.S. Navy surface ships, current models cannot produce a repeatable answer when the details of the acquisition program are not well defined. This thesis formulates a parametric model that predicts the average procurement cost of a conventional U.S. Navy surface ship based upon known (or assumed) physical and performance characteristics. The source data for the cost model is obtained from U.S. Weapons Systems Costs, a tabulation of annual procurement costs for major system programs, published by Data Search Associates. Standard regression techniques return cost estimating relationships able to predict average procurement cost from ship light displacement, ship overall length, ship propulsion shaft horsepower or number of propulsion engines. The formulated parametric cost model is approximate and appropriate only for rough order of magnitude studies, but can be used by the DoD cost community to produce justifiable estimates when other models do not have sufficient information to generate an answer.

This book was released on 1999-06-01 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: With few effective decision-making tools to assess the affordability of major weapon systems, management of total ownership costs is continually misunderstood. Cost analysis provides a quick and reliable assessment of affordability. Because there is no standardized method for calculating reliable estimates of operating and support (O&S) costs (the principal component of total ownership cost), this thesis formulates a parametric cost model which can be used to determine the annual O&S costs of U.S. Navy (non-nuclear) surface ships based on known (or assumed) physical characteristics and manpower expectations. Source data for the cost model is obtained from the Navy Visibility and Management of O&S Costs (VAMOSC) database, a historical cost database maintained by the Naval Center for Cost Analysis (NCCA). Through standard regression and data analysis techniques, cost estimating relationships are developed for three major cost drivers: ship light displacement, ship overall length, and ship manpower. The formulated parametric cost model is a top-level and fairly reliable representation of average annual O&S cost, and it can be used by the DOD cost community to perform component cost analyses or independent cost estimates.

This book was released on 2000-12-01 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study provides parametric O&S cost models for future US Navy aircraft acquisition programs based on physical and performance parameters. The proposed parametric cost models provide decision makers with a tool for developing rough-order-of-magnitude annual O&S cost estimates for future US Navy aircraft acquisition programs. The historic aircraft cost data was provided by the Naval Center for Cost Analysis (NCCA) in a spreadsheet format and the data were extracted from the Navy Visibility and Maintenance of Operating and Support Cost (VAMOSC) data warehouse. After validating the assumption that the average annual O&S cost for any aircraft type/model/series is constant from year to year, cost estimating relationships are developed. The first model developed is based on multivariate regression. In this case, forward stepwise regression was used to find the model with the best fit. Since the multivariate regression model turns out to be impractical, having more than 30 variables in the equation, a tree-based model is presented as an alternative. Additionally, single variable cost estimating relationships are formulated based on the physical and performance parameters length, weight, and thrust.

Available in PDF, EPUB and Kindle. Book excerpt: Over the past several decades, increases in acquisition costs for U.S. Navy combatants have outpaced the rate of inflation. To understand why, the authors of this book examined two principal source categories of ship cost escalation (economy-driven factors and customer-driven factors) and interviewed various shipbuilders. Based on their analysis, the authors propose some ways the Navy might reduce ship costs in the future.

Book excerpt: The acquisition of major weapon systems is an extremely complex process involving interrelationships between a number of organizations. This thesis presents a general procedure and develops parametric cost estimate for Naval ship acquisition cost. Two different models are developed, one a 9-subsystem model, the other a single total cost model. The models were developed using the linear least squares regression technique with MINITAB statistical program on a data base of Destroyer type ships built in 1954-1966. A comparison of these two estimates with the existing RMC model's estimate was examined for Patrol Frigate construction data. The 9-subsystem estimate could be compared favorably with the RMC model cost estimate. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: NAVSEA Cost Estimating Handbook (2005) *Printed in Black and White to reduce cost* Naval Sea Systems Command (NAVSEASYSCOM or NAVSEA) explains how a NAVSEA cost estimate is an assemblage of separate, distinct, and subordinate parts and each subordinate part is treated as a whole to be separated into its elements for examination, modification, and/or updating before becoming a part of a total estimate. The NAVSEA cost estimating process is at once analytical and synthesizing in nature using established methods and valid data, to estimate the future costs of a program, based on what is known today. It is an organized approach designed to accurately calculate the future costs of ships, submarines, and weapons systems. The management of a cost estimate involves continually updating the estimate with actual data as they become available, revising the estimate to reflect changes, and analyzing differences between estimated and actual costs-for example, using data from a reliable earned value management (EVM) system. Anyone that has ever managed a project knows the value of a good cost estimate.The ability to generate reliable cost estimates is a critical function, necessary to support the NAVSEA capital programming process. Without this ability NAVSEA is at risk of experiencing cost overruns, missed deadlines, and performance shortfalls-all recurring problems that program assessments too often reveal. Furthermore, cost increases often mean that NAVSEA cannot fund as many programs as intended or deliver them when promised. The methodology outlined in this guide is a compilation of best practices that federal cost estimating organizations and industry use to develop and maintain reliable cost estimates throughout the life of a NAVSEA acquisition program.

Download or read book An Operating and Support Cost Model for Aircraft Carriers and Surface Combatants written by Henry L. Eskew and published by . This book was released on 1977 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report is in two parts. Part I details the development and implementation of an operating and support cost model for aircraft carriers and surface combatants. Twenty-three O and S cost elements were identified and defined, with close adherence being maintained to the draft CAIG Operating and Support Cost Development Guide for Naval Ships, the Navy Resource Model (NARM), and the work of the Visibility and Management of Support Costs (VAMOSC) Study Group. Cost data were obtained from three principal sources: Navy Cost Information System (NCIS), NARM Program Factors, and the Center for Naval Analyses' SOCER Study. Procedures consisting of parametric cost-estimating relationships, cost factors and 'thruput' estimates were developed for the full set of cost elements. Those procedures were incorporated into an automated model which was then used to estimate annual O and S costs for the DD-963 and the FFG-7. Part II of the report summarizes all the work accomplished under the contract and provides a listing of all technical reports submitted. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: With the end of the Cold War, the winds of military downsizing are blowing all over the world. Downsizing means fewer personnel, less facilities and smaller military budget. Therefore, understanding the relationships among factors responsible for force operating costs is extremely important when facing downsizing budgetary decisions. This study analyzes the U.S. Navy main combatant vessels' Operating and support costs. It seeks to reveal basic relationships of O and S costs through accounting and structural methods. The accounting oriented analysis found the VAMOSC-SHIPS and Jane's combined database to be relatively accurate with the exception of nuclear submarines and nuclear aircraft carriers. The structural analysis found that the overhaul cost should be analyzed separately due to essential differences used to calculate overhaul costs and a 1985 policy revision to ship overhaul. O and S cost relationships between factors other than overhauls were strong. Manpower was found to have the most dramatic effect on determining O and S costs.

This book was released on 1982 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: A common first step in estimating costs of naval ship categories is to use a linear relationship based on ship displacement. Such estimates represent rough initial approximations. This process can be used, however, with better accuracy to estimate the cost of procurement of aggregations of naval ships and classes. Cost estimating relationships (CERs) are developed in this paper for such applications.

Available in PDF, EPUB and Kindle. Book excerpt: This study investigates the relationship of the component weights of US Navy Surface Escort Ships and their corresponding costs of construction. The procedures of various US Navy agencies who conduct Surface Ship Costing are described, with emphasis upon the method followed by COMNAVSEASYSCOM, Washington D.C. A statistical analysis is provided which focuses upon multiple linear regression techniques applied to the weight/cost relationship. Additionally, the research includes the investigation of non-weight explanatory variable contribution to the various regression models. The analysis concludes that linear relationships do exist between the variables. The statistical evidence provided suggests that linear regression provides equivalent results to non-linear logarithmic transformation of the dependent cost variable. Further, the analysis indicates that the inclusion of non-weight dummy variables, such as contract type for vessel construction, enhance models with strictly weight explanatory variables. The models developed herein lack the precision demanded of budgetary cost estimating. However, the equations will generate point estimates that may add credence to existing methods, especially within concept formulation or tradeoff studies.

Download or read book Estimation of Destroyer Type Naval Ship Procurement Costs written by and published by . This book was released on 1973 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report presents three models by which the total procurement cost of Destroyer and Destroyer Escorts may be estimated. One model uses 9 subsystem cost estimating relationships (CERs) to obtain a total cost estimate; the second model uses 4 subsystem CERs; the final model is a single total cost equation. The CERs were developed using the linear least squares regression technique on a data base of ships built from 1954-66. The CERs use input variables that may be determined long before actual ship construction begins. This fact, and the precision of the model estimates, recommend usage of these models in cost-effectiveness analysis. The Patrol Frigate Project is used as a sample application, wherein model estimates compare favorably with the current NAVSHIPS cost estimates. (Author).

Download or read book Navy Ship Acquisition Options for Lower Cost Ship Designs Issues for Congress CRS Report for Congress written by and published by . This book was released on 2005 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rising procurement costs for Navy ships have recently emerged as a matter of concern for both Navy officials and some Members of Congress who track Navy-related issues. Combined with constraints on ship-procurement funding, these rising costs have caused the Navy to reduce planned ship procurement rates. The issue for Congress is how to respond to rising Navy ship procurement costs. Aside from reducing planned ship procurement rates, one option would be to reduce procurement costs by shifting from currently planned designs to designs with lower unit procurement costs. Lower cost designs for attack submarines, aircraft carriers, larger surface combatants, and smaller surface combatants have been proposed in recent reports by the Congressional Budget Office (CBO), DoD's Office of Force Transformation (OFT), and the Center for Strategic and Budgetary Assessments (CSBA). Options for lower cost designs can be generated by reducing ship size; shifting from nuclear to conventional propulsion; shifting from a hull built to military survivability standards to a hull built to commercial ship survivability standards; or using a common hull design for multiple classes of ships. Compared to the current Virginia-class, nuclear-powered attack submarine (SSN) design, lower cost options include a non-nuclear-powered submarine equipped with an air-independent propulsion (AIP) system and a reduced-cost SSN design using new technologies now being developed. Compared to today's large, nuclear-powered aircraft carriers, lower cost options include a medium-sized, conventionally powered carrier based on either the LHA(R) amphibious assault ship design or a commercial-like hull, and a small, high-speed carrier using a surface effect ship (SES)/catamaran hull. Compared to the current 14,000-ton DD(X) destroyer design, lower cost options include a newly designed 9,000-ton surface combatant (SC(X)), a 6,000-ton frigate (FFG(X)), or a low-cost gunfire support ship.
