Software development effort estimation is essential for software project planning and management. In this study, we present a spectral clustering algorithm based on symmetric matrixes as an option data processing. It expected that constructing model more similar can increase the accuracy. The research methods employ symmetrical processing experimentation. Four experimental models function point...

Software development effort estimation is the process of calculating the effort required to develop or maintain software based on the input, which is partial, tentative and/or strident. Efficient project estimation is one of the most difficult and significant activities in project development. “Effort Estimation” is supposed to be fateful because of infrequency, uniqueness, underestimation bias...

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 , ...

There is a growing body of evidence to suggest that significant benefits may be gained from augmenting current approaches to software development effort estimation, and indeed other project management activities, with models developed using fuzzy logic and other soft computing methods. The tasks undertaken by project managers early in a development process would appear to be particularly amenab...

Effective cost estimation is the most challenging activity in software development. Software cost estimation is not an exact science. Cost estimation process involves a series of systematic steps that provide estimate with acceptable risk. Some prevalent LOC based models areBailey Basili model, Alaa F. Sheta G.E. Model, and Alaa F. Sheta, Model 2 [1] .Two new models, based on fuzzy logic sizing...

Accurate estimation of software’s cost isone of the most intricate activity during the software development lifecycle.There are many factors that directly or indirectly affect the development cost of any software and these factors range from the size of the software to the experience of project manager. Calculating and interpreting these factors would be much valuable in software cost estimatio...
