An Efficient Approach to Develop Software Cost Estimation Model Using Case-based Reasoning and Agent Technology
One of the most important tasks for IT professionals is software development cost estimation. This critical task affects the firm's software investment decisions before bidding for a contract or committing required resources to that project. Under-estimation may lead to unexpected increase in budget, delay of project completion or its low quality, while over-estimation may lead to losing busine...
متن کاملComponent Retrieval Using Conversational Case-Based Reasoning
Component retrieval, about how to locate and identify appropriate components, is one of the major problems in component reuse. It becomes more critical as more reusable components come from component markets instead of from an in-house component library, and the number of available components is dramatically increasing. In this paper, we review the current component retrieval methods and propos...
متن کاملFuzzy Case-Based Reasoning Models for Software Cost Estimation
Providing a timely estimation of the likely software development effort has been the focus of intensive research investigations in the field of software engineering, especially software project management. As a result, various cost estimation techniques have been proposed and validated. Due to the nature of the software-engineering domain, software project attributes are often measured in terms...
متن کاملUsing k-d Trees to Improve the Retrieval Step in Case-Based Reasoning
Retrieval of cases is one important step within the case-based reasoning paradigm. We propose an improvement of this stage in the process model for nding most similar cases with an average eeort of Olog2n], n number of cases. The basic idea of the algorithm is to use the heterogeneity of the search space for a density-based structuring and to employ this precomputed structure, a k-d tree, for e...
متن کاملExploring case-based reasoning for web hypermedia project cost estimation
This paper compares several methods of analogy-based effort estimation, including the use of adaptation rules as a contributing factor to better estimation accuracy. Two data sets are used in the analysis. Results show that best predictions were obtained for the dataset that presented a continuous “cost” function and was more “unspoiled”.
