In recent years, utilization of feature selection techniques has become an essential requirement for processing and model construction in different scientific areas. In the field of software project effort estimation, the need to apply dimensionality reduction and feature selection methods has become an inevitable demand. The high volumes of data, costs, and time necessary for gathering data , ...

Accurate effort prediction is an ongoing challenge to software engineers. It is an important task in the management of software projects. Effort estimation is the challenging and is an important area in the software project management research field. The development of software has always been characterized by the parameters that contain certain level of fuzziness. This requires some degree of ...

Due to the intangible nature of “software”, accurate and reliable software effort estimation is a challenge in the software Industry. It is unlikely to expect very accurate estimates of software development effort because of the inherent uncertainty in software development projects and the complex and dynamic interaction of factors that impact software development. Heterogeneity exists in the s...

Accurately estimating the software size, cost, effort and schedule is probably the biggest challenge facing software developers today. It has major implications for the management of software development because both the overestimates and underestimates have direct impact for causing damage to software companies. Lot of models have been proposed over the years by various researchers for carryin...

Both Agile Software Development (ASD) and Global Software Development (GSD) are 21 century trends in the software industry. Many studies are reported in the literature wherein software companies have applied an agile method or practice GSD. Given that effort estimation plays a remarkable role in software project management, how do companies perform effort estimation when they use agile method i...

Introduction Traditional software development is characterized by the structured programming paradigm introduced in the late 60’s and early 70’s. This paradigm relies on top-down functional decomposition to derive software modules. The structured programming paradigm provides a monolithic view of the software development process. Traditional software effort estimation models capture this monoli...

The construction of software cost estimation models remains an active topic of research. The basic premise of cost modelling is that a historical database of software project cost data can be used to develop a quantitative model to predict the cost of future projects. One of the difficulties faced by workers in this area is that many of these historical databases contain substantial amounts of ...

Software development effort is one of the most important metrics that must be correctly estimated in software projects. Analogy-based estimation (ABE) and artificial neural networks (ANN) are the most popular methods used widely in this field. These methods suffer from inconsistent and irrelevant projects that exist in the software project datasets. In this paper, a new hybrid method is propose...

The growing complexity and number of software projects requires both increasingly more experienced developers, testers and other specialists as well as a larger number of persons to fill these roles. This leads to increased personnel and management costs and also makes effort and cost estimation at task and activity levels more difficult for software development companies. An automated solution...

Accurate software development effort estimation is a critical part of software projects. Effective development of software is based on accurate effort estimation. Although many techniques and algorithmic models have been developed and implemented by practitioners, accurate software development effort prediction is still a challenging endeavor in the field of software engineering, especially in ...
