Accurate software development cost estimation is important for effective project management such as budgeting, project planning and control. So far, no model has proved to be successful at effectively and consistently predicting software development cost. A novel neuro-fuzzy Constructive Cost Model (COCOMO) is proposed for software cost estimation. This model carries some of the desirable featu...

This contribution deals with problems related to an effort estimation of the software projects which are connected to the development of secured products. The aim of this contribution is to present an option of an effective consideration of the effort which is connected with the software products development. The FPA and COCOMO II methods for cost estimation are extended by the security factors...

Financial health of many organizations now-a-days is being affected by investment in software and their cost estimation. Therefore, to provide effective cost estimation models are the most complex activity in software engineering fields. This paper presents a fuzzy clustering and optimization model for software cost estimation. The proposed model uses Pearson product-moment correlation coeffici...

As software cost drivers are fuzzy and uncertain, software cost estimates are prone to a certain degree of estimation errors especially in their early stages of software development life cycle. However, most of the existing software cost estimation models in present literature only generate a single point estimate and do not explicitly reveal the degree of risks caused by their inaccuracies. Th...

In most software development organizations, there is seldom a one-to-one mapping between software developers and development tasks. It is frequently necessary to concurrently assign individuals to multiple tasks, and to assign more than one individual to work cooperatively on a single task. A principal goal in making such assignments should be to minimize the effort required to complete each ta...

Nowadays, software companies have to mange different software development processes based on different time, cost, and number of staff sequentially, which is a very complex task and supports project planning and tracking. Software time, cost and manpower estimation for separate projects is one of the critical and crucial tasks for project managers. Accurate software estimation at an early stage...

Problem statement: Software development effort estimation is the process of predicting the most realistic use of effort required for developing software based on some parameters. It has always characterized one of the biggest challenges in Computer Science for the last decades. Because time and cost estimate at the early stages of the software development are the most difficult to obtain and th...

COCOMO II is an effort to update software cost estimation models, such as the 1981 COnstructive Cost MOdel and its 1987 Ada COCOMO update. Both these models have experienced difficulties in estimating software projects of the 90s due to challenges such as non-sequential and rapid-development process models; reuse-driven approaches involving commercial-off-the-shelf (COTS) packages, reengineerin...

Software Cost Estimation (SCE) is considered one of the most important sections in software engineering that results in capabilities and well-deserved influence on the processes of cost and effort. Two factors of cost and effort in software projects determine the success and failure of projects. The project that will be completed in a certain time and manpower is a successful one and will have ...
