“…Da Costa's results have contributed to paraconsistent logic's ongoing transformation into a progressive and promising area of research. In recent years, several studies have been published describing the application of paraconsistent annotated evidential logic Eτ to a diverse range of areas, such as, for example, frame-based knowledge management [5], construction and implementation of electronic circuits [13], decision-making for evaluation of the plans for a new factory [9], intelligent control systems for autonomous mobile robots [29], treatment of inconsistencies in case-based reasoning systems [14], quality assessment of a web commerce site [6], digital signal processing [20], support for medical decision-making [25], [26], analysis of structural reliability in rock excavations [24] and others. However, the application of paraconsistent annotated evidential logic Eτ to evaluation of companies is a problem that has never been explored.…”
