one of the most important and valuable goal of software development life cycle is software cost estimation or sce. during the recent years, sce has attracted the attention of researchers due to huge amount of software project requests. there have been proposed so many models using heuristic and meta-heuristic algorithms to do machine learning process for sce. cocomo81 is one of the most popular...
Neural networks were used to estimate the cost of jet engine components, specifically shafts and cases. The neural network process was compared with results produced by the current conventional cost estimation software and linear regression methods. Due to the complex nature of the parts and the limited amount of information available, data expansion techniques such as doubling-data and data-cr...
The number of information systems in the world wide web is growing continuously. However, the development process of web information systems is not yet suuciently supported by adequate methods during all phases. Especially methods for cost estimation are missing. Thus, the development of web information systems does not only bear the risk of unforeseen high implementation cost, but also of unco...
Software project management software is the most important activity in software development, because it contains the whole software development process, from beginning to end. Software cost estimation is a challenge task in the software project management. It is an old activity in computer industry from 1940s and has been developed many times. Effort, only covers part of the cost of a software ...
This paper summarizes estimation knowledge through a review of surveys on software effort estimation. Main findings were that: (1) Most projects (60-80%) encounter effort and/or schedule overruns. The overruns, however, seem to be lower than the overruns reported by some consultancy companies. For example, Standish Group’s ‘Chaos Report’ describes an average cost overrun of 89%, which is much h...
a successful software should be finalized with determined and predetermined cost and time. software is a production which its approximate cost is expert workforce and professionals. the most important and approximate software cost estimation (sce) is related to the trained workforce. creative nature of software projects and its abstract nature make extremely cost and time of projects difficult ...
