PENABAD-SANZ, Laksmi et al. Graphical approach for classifying cars utilization in rental fleets. Ingeniería Mecánica [online]. 2022, vol.25, n.3, pp. 19-26.  Epub Dec 20, 2022. ISSN 1815-5944.

Nomograms are instruments that facilitate the interpretation of numerical calculation, based on the graphic representation of equations with a practical level of precision. This article aims to show the nomogram called Graphic of State of Rationality, conceived by the authors and its use, for classifying the degree of rationality of the use of vehicles. The Nomogram allows simplifying the practical and periodic evaluation of vehicles. In the investigation, the analysis of lease fleets was carried out according to several criteria. The fleet was segmented in homogeneous blocks according to the car model, the season and the time in exploitation. Finally, it was defined that the influence on the negative economic impact of the inactive time of vehicles is greater than that the time out of service, which is contrary to the generally accepted criteria in which, maintenance is the fundamental cause of irrationality in the use of vehicles and indicates the need of decision -making associated with the operations function.

Keywords : nomograms; Graphic of State of Rationality; lease fleets.
