00925njm 22002777a 4500 dc Muxika Olasagasti, Eñaut author 2021 A unified evaluation framework for stochastic tools is developed in this paper. Firstly, we provide a set of already existing quantitative and qualitative metrics that rate the relevant aspects of the performance of a stochastic prognosis algorithm. Secondly, we provide innovative guidelines to detect and minimize the effect of side aspects that interact on the algorithms’ performance. Those aspects are related with the input uncertainty (the uncertainty on the data and the prior knowledge), the parametrization method and the uncertainty propagation method. The proposed evaluation framework is contextualized on a Lithium-ion battery Remaining Useful Life prognosis problem. As an example, a Particle Filter is evaluated. On this example, two different data sets taken from NCA aged batteries and two semi-empirical aging models available in the literature fed up the Particle Filter under evaluation. The obtained results show that the proposed framework gives enough details to take decisions about the viability of the chosen algorithm. 2313-0105 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=164699 https://hdl.handle.net/20.500.11984/5409 prognosis stochastic algorithm particle filter evaluation metric uncertainty propagation Unified Evaluation Framework for Stochastic Algorithms Applied to Remaining Useful Life Prognosis Problems
