Software cost estimation

The paper gives an overview of the state of the art of software cost estimation (SCE). The main questions to be answered in the paper are: (1) What are the reasons for overruns of budgets and planned durations? (2) What are the prerequisites for estimating? (3) How can software development effort be estimated? (4) What can software project management expect from SCE models, how accurate are estimations which are made using these kind of models, and what are the pros and cons of cost estimation models

Estimating the Costs of Foundational Public Health Capabilities: A Recommended Methodology

The Institute of Medicine’s 2012 report on public health financing recommended the convening of expert panels to identify the components and costs of a “minimum package of public health services” that should be available in every U.S. community. The report recommended that this minimum package include a core set of public health programs that target specific, high-priority preventable health problems and risks, along with a set of “foundational public health capabilities” that are deemed necessary to support the successful implementation of public health programs and policies. In response to this recommendation, the Robert Wood Johnson Foundation, in collaboration with the US Centers for Disease Control and Prevention and other national professional associations, formed the Public Health Leadership Forum, an expert consensus panel process to identify a recommended set of core programs and foundational capabilities for the nation. The Forum’s initial charge focused on the specification of foundational public health capabilities. The Foundational Capabilities Workgroup was formed as a part of the Forum to identify and define the elements to be included as foundational capabilities for governmental public health agencies at both state and local levels. The Robert Wood Johnson Foundation asked the National Coordinating Center for Public Health Services and Systems Research based at the University of Kentucky to convene a second expert panel workgroup, the Workgroup on Public Health Cost Estimation, to develop a methodology for estimating the resources required to develop and maintain foundational capabilities by governmental public health agencies at both state and local levels. Working in parallel with the Foundational Capabilities Workgroup, this Cost Estimation Workgroup has considered relevant cost-accounting models and cost estimation methodologies, and reviewed related cost estimation studies, in order to make recommendations on an approach for generating first-generation estimates of the costs associated with developing and maintaining foundational capabilities

Overnight Cost Estimation Ofindonesia's Cogeneration Power Plant for Industrial Processes

Indonesia's cogeneration power plant for industrial processes (PeLUIt) is needed to be implemented in Indonesia. Economic analysis is an important factor for PeLUIt implementation. One of the data that needs in the analysis is overnight cost. This research estimates HTGR's overnight cost by using scaling law.By using the estimated value, it can be calculated the PeLUIt overnight cost. The research's purpose is to obtain an estimation of overnight costs of PeLUIt. The estimation result shows the overnight cost of PeLUIt. PeLUIt 10 MWth has an overnight cost 166,26 million USD. PeLUIt 30 MWth has an overnight cost 233,49 million USD. PeLUIt 50 MWth has an overnight cost 281,31 million USD. PeLUIt 100 MWth has an overnight cost 371,86 million USD. PeLUIt 350 MWth has an overnight cost 657,16 million USD

A systematic review of software development cost estimation studies

This paper aims to provide a basis for the improvement of software estimation research through a systematic review of previous work. The review identifies 304 software cost estimation papers in 76 journals and classifies the papers according to research topic, estimation approach, research approach, study context and data set. A web-based library of these cost estimation papers is provided to ease the identification of relevant estimation research results. The review results combined with other knowledge provide support for recommendations for future software cost estimation research, including: 1) Increase the breadth of the search for relevant studies, 2) Search manually for relevant papers within a carefully selected set of journals when completeness is essential, 3) Conduct more studies on estimation methods commonly used by the software industry, and, 4) Increase the awareness of how properties of the data sets impact the results when evaluating estimation methods

An approach to software cost estimation

A general procedure for software cost estimation in any environment is outlined. The basic concepts of work and effort estimation are explained, some popular resource estimation models are reviewed, and the accuracy of source estimates is discussed. A software cost prediction procedure based on the experiences of the Software Engineering Laboratory in the flight dynamics area and incorporating management expertise, cost models, and historical data is described. The sources of information and relevant parameters available during each phase of the software life cycle are identified. The methodology suggested incorporates these elements into a customized management tool for software cost prediction. Detailed guidelines for estimation in the flight dynamics environment developed using this methodology are presented

Software Cost Estimation using Single Layer Artificial Neural Network

The most challenging task of software project management is the cost estimation. Cost estimation is to accurately assess required assets and schedules for software improvement ventures and it includes a number of things under its wide umbrella, for example, estimation of the size of the software product to be produced, estimation of the effort required, and last but not the least estimating the cost of the project. The overall project life cycle is impacted by the accurate prediction of the software development cost. The COCOMO model makes employments of single layer feed forward neural system while being actualized and prepared to utilize the perceptron learning algorithm. To test and prepare the system the COCOMO dataset is actualized. This paper has the goal of creating the quantitative measure in not only the current model but also in our proposed model
