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: Cost estimating relationships based on the observed (reported) cost and weight (full load displacement) of U.S. Navy ships are derived for the purpose of applying these cost estimating relationships to ships in the fleets of both the U.S. and USSR. This application results in broad, general comparisons that, in the aggregate, provide useful trend comparisons. These cost estimating relationships produce varying results on a class basis, but within each group or category of ships the class overestimates tend to be offset by class underestimates to yield a relatively small category error. This paper updates major portions of IDA Paper P-1530, Simple Relationships for Estimating Procurement Cost of U.S. Navy Ship Categories, dated March 1982.

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.

Download or read book Cost Estimating Relationship Associating Engineering Drawing Quality with Installation Cost Growth for USN Ship Alterations written by Kurt Willstatter and published by . This book was released on 1988 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is an analysis of existing feedback in the Fleet Modernization Program (FMP) planning and design process using the FFG-7 class of ships as a case study. This analysis attempts to relate the engineering drawing revision rate (inverse measure of drawing quality) and the number of ships affected by those drawing revisions (measure of availability concurrence) to the cost growth attributable to the FMP portion of U.S. Navy ship availabilities. Due to the lack of actual cost data, budget estimates were used as a surrogate and unfortunately firm relationships could not be established. However, the methodology developed has potential for application to any large ship class which may experience numerous concurrent availabilities, as actual cost data become available. It is meant to be a tool for the engineering design agent to assess the financial impact of the quality of engineering design products on the installing activities and to assess the potential value of policy changes which improve the quality of those products. Keywords: Data bases, Theses, Regression statistics. (KR).

Download or read book Improving the Parametric Method of Cost Estimating Relationships of Naval Ships written by Jeremy Ungtae Lee and published by . This book was released on 2014 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: In light of recent military budget cuts, there has been a recent focus on determining methods to reduce the cost of Navy ships. A RAND National Defense Research Institute study showed many sources of cost escalation for Navy ships. Among them included characteristic complexity of modem Naval ships, which contributed to half of customer driven factors. This paper focuses on improving the current parametric cost estimating method used as referenced in NAVSEA's Cost Estimating Handbook. Currently, weight is used as the most common variable for determining cost in the parametric method because it's a consistent physical property and most readily available. Optimizing ship design based on weight may increase density and complexity because ship size is minimized. This paper will introduce electric power density and outfit density as additional variables to the parametric cost estimating equation and will show how this can improve the early stage cost estimating relationships of Navy ships.

Book excerpt: The study addresses the problem of estimating the development, procurement, and installation costs of surface ship electronic warfare equipment of the future. The Cost Estimating Relationships (CERs) were developed using the following factors: year of development, weight, volume, sensitivity, power output, gain, complexity and dummy variables for active equipment, equipment designed for large ships and one for those designed for small ships. Cost estimates are made for three systems presently under development by Raytheon Company and Hughes Aircraft Company under a design-to-price program.

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 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.

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).

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 Cost Prediction Via Quantitative Analysis of Complexity in U.S. Navy Shipbuilding written by Aaron Travis Dobson and published by . This book was released on 2014 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the sophistication and technology of ships increases, U.S. Navy shipbuilding must be an effective and cost-efficient acquirer of technology-dense one-of-a-kind ships all while meeting significant cost and schedule constraints in a fluctuating demand environment. A drive to provide world-class technology to the U.S. Navy's warfighters necessitates increasingly complex ships, which further augments the non-trivial problem of providing cost effective, on-schedule ships for the American taxpayer. The primary objective of this study was to quantify, assess, and analyze cost-predictive complexity-oriented benchmarks in the pre-construction phase of the U.S. Navy's ship acquisition process. This study used commercially-available software such as Mathwork's MATLAB software to analyze the numerical cost data and assess the fidelity of the predictive benchmarks to the datasets. The end result was that a consideration of complexity via the methods and algorithms established in this study supported an exponential cost versus complexity relationship to refine the current cost estimation methods and software currently in use in U.S. Navy shipbuilding. Specifically, it was found that for the subsystems under analysis, acquisition/contract cost per unit was highly correlated with unit complexity according to the relationship, cost/unit ($M,USD) = 23.100 + e^0.015C.

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.
