Fuzzy Analogy: A New Approach for Software Cost Estimation
Ali Idri, Alain Abran, Taghi M. Khosgoftaar · 2001
Estimation models in software engineering are used to predict some important attributes of future entities such as software development effort, software reliability and programmers productivity. Among these models, those estimating software effort have motivated considerable research in recent years. Estimation by analogy is one of the most attractive technique in software effort estimation field. However, the procedure used in estimation by analogy is not yet able to handle correctly categorical data such as `very low', `complex' and `average'. In this paper, we propose a new approach based on reasoning by analogy, fuzzy logic and linguistic quantifiers to estimate effort when the software project is described either by categorical or numerical data.
