Scientists from the universities of California (USA), McMaster (Canada) and Murcia, has verified a new representation model based on mixtures designed to compare the reliability of new and used systems.
The researcher at the University of Murcia, Jorge Navarro, said in the study's conclusions that "we have similar representations for the residual lifetime of systems used, and we can compare our results with the new."
He adds that "in this way, for example, you may find that if we buy new cars, marked" A "is more reliable than the" B ", but if we decide to buy a car three years ago the opposite occurs.
The other authors of the study, published in the journal "Journal of Applied Probability", is the professor of the University of California (USA) Francisco Samaniego and McMaster University in Hamilton (Canada) N.
Balakrishnan.
