A cornerstone of software project management is effort estimation, the process by which effort is forecasted and used as basis to predict costs and allocate resources effectively, so enabling projects to be delivered on time and within budget. Effort estimation is a very complex domain where the relationship between factors is non-deterministic and has an inherently uncertain nature, and where ...

Software effort estimation is still a significant challenge for software management. Although Functional Size Measurement (FSM) methods have been standardized and have become widely used by the software organizations, the relationship between functional size and development effort still needs further investigation. Most of the studies focus on the project cost drivers and consider total softwar...

Accurate simulation provides a significant means for cost reduction during planning and operation of manufacturing installations. Within the projects Realistic Robot Simulation the standards Robot Controller Simulation (RCS) Interface and Virtual Robot Controller (VRC) Interface were defined by international consortia of leading car makers, robot and simulator manufacturers and line builders, w...

This paper examines how a team of software professionals goes about estimating the effort of a software project using a judgment-based, bottom-up estimation approach. By employing a social practice perspective that highlights the distributed character of expertise and conceives actions as mediated by cultural tools, the paper analyzes the interactional process through which the estimation tasks...

This article explores a number of existing project cost estimation techniques to investigate how the estimation can be done in a more accurate and effective manner. The survey looks into various estimation models that utilize many theoretical techniques such as statistics, fuzzy logic, case-based reasoning, analogies, and neural networks. As the essence of conventional estimation inaccuracy lie...

Software project managers have expressed concern over their inability to estimate accurately the costs associated with software development. Various cost estimation methods are available for use in software development process but concern lies in selecting better software cost estimation model to arrive at accurate cost estimation. This paper gave an overview of software cost estimation and ans...

Software Effort estimation is the process of predicting the effort required to develop software project based on incomplete, uncertain and/or noisy input. Researchers have been working on estimation models to predict effort to be spent on a software project, which is still a complex problem. Estimation models derived by researchers are conclusion of studying large number of completed software p...
