This book was released on 1970 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: The paper discusses the feasibility of developing regression models to predict the total cost of a Navy ship using the physical weights of the ship components as independent variables was investigated. The various forms of regression analyses fall under the following three categories: Linear multiple regression analysis; Non-linear multiple regression analysis; and Adding-up process, which is an aggregation of two-variable regression analyses. It was found that the linear model is preferable over the non-linear model and the adding-up process. If the samples are properly selected, linear models which are statistically significant can be derived. Given its superiority over the other two models, the degree of accuracy of the linear model is still not high enough to produce a dependable point estimation for the total cost of the ship.

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.

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.

Download or read book Estimation and Analysis of Navy Shipbuilding Program Disruption Costs written by Colin P. Hammon and published by . This book was released on 1980 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Changes in ship design or specifications disrupt work on a ship, and can disrupt work throughout an entire shipyard. This increases costs. Additionally, government-directed changes may be the legal basis for claims when the contractor overruns cost and schedule for any reason. Outstanding claims for equitable adjustment based primarily on alleged delay and disruption due to Government changes reached the unprecedented level of $2.5 billion in 1978. Many within the Navy would like to move the disruption issue out of the courts by paying the full cost of changes as they are implemented. This paper reports a test of the feasibility of a statistical method for fully pricing shipbuilding change manhours. (Author).

Download or read book An Analysis of the Navy s Fiscal Year 2011 Shipbuilding Plan written by and published by . This book was released on 2010 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Navy is required by law to submit a report to the Congress each year that projects the service's shipbuilding requirements, procurement plans, inventories, and costs over the coming 30 years. Since 2006, the Congressional Budget Office (CBO) has been performing an independent analysis of the Navy's latest shipbuilding plan at the request of the Subcommittee on Seapower and Expeditionary Forces of the House Armed Services Committee. This CBO report, the latest in that series, summarizes the ship requirements and purchases described in the Navy's 2011 plan and assesses their implications for the Navy's funding needs and ship inventories through 2040. The new plan appears to increase the required size of the fleet compared with earlier plans, while reducing the number of ships to be purchased, and thus the costs for ship construction, over the next three decades. Despite those reductions, the total costs of carrying out the 2011 plan would be much higher than the funding levels that the Navy has received in recent years.

This book was released on 2002 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: A companion piece to MR-1526 that examines the pros and cons of applying advance appropriations across a broader segment of the Navy shipbuilding program than just aircraft carriers. The entire cost of a ship is normally included in the congressional budget for the year of construction start, which can cause large year-to-year fluctuations in the shipbuilding budget and complicate budget management. This report analyzes an alternative strategy, advance appropriations, whereby the full cost of a ship is distributed over several budget years. This strategy can reduce fluctuations in the budget level and can create the equivalent of a loan against future budgets, but also constrains management flexibility in coping with unexpected events.
