PENABAD-SANZ, Laksmi; RODRIGUEZ-RAMOS, Pedro Antonio  e  IZNAGA-BENITEZ, Arsenio Miguel. Freight vehicle condition monitoring through the availability. Dyna rev.fac.nac.minas [online]. 2018, vol.85, n.205, pp.355-362. ISSN 0012-7353.  http://dx.doi.org/10.15446/dyna.v85n205.68443.

The application of decision making approaches based on systems degradation monitoring in real situations are difficult. Among those difficulties are methods complexity and data, technology and capable personnel availability. In this paper, a way for monitoring freight vehicle condition through availability assessment is proposed. In order to do that, the rational use limit condition of freight vehicles is proposed and a mathematical model of the availability threshold linked with operation economic results is presented. The latest makes possible to value the vehicle operation convenience. The application of the proposal to a fleet shows its possibilities in real conditions. An “Almost perfect” agreement degree between the availability assessment results and the economic result of the vehicle operation was obtained.

Palavras-chave : availability; availability threshold; rational use; transport fleet; decision making.
