A Fuzzy Logic Model Based upon Reused and New & Changed Code for Software Development Effort Estimation at Personal Level

Unless engineers have the capabilities provided by personal training, they cannot properly support their teams or consistently and reliably produce quality products. This paper presents a research aimed to compare a model based upon fuzzy logic with a multiple linear regression model. From a replicated experiment using a sample integrated by sixteen developers and 94 small programs these two models are derived. A common process as well as inside of a controlled environment this experiment is based. These comparisons based upon analysis of variance (ANOVA), magnitude of relative error (MRE) as well as multiple range tests show that a fuzzy logic model based on new and changed code as well as reused code can be an alternative for the software development effort estimation at personal level
