Analysis of RUL dynamics and uncertainty via time transformation Pierre Dersin, Roberto Rocchetta Reliability Engineering and System Safety, 2026 This work introduces a novel analytical method to analyze the dynamics of remaining useful life (RUL) and quantify uncertainty in its estimation. The approach employs a time transformation that makes the mean residual life (MRL) a linear function of transformed time, enabling the derivation of explicit RUL confidence bounds. Once mapped back to physical space, the bounds quantify aleatoric (stochastic) uncertainty in RUL and yield asymmetrical confidence intervals for both parametric and non-parametric lifetime distributions. The approach leverages a key feature of reliability distributions: the average RUL loss rate, k , in transformed time, facilitating a direct derivation of confidence bounds. In parametric cases, k is uniquely defined by the reliability distribution parameters, while for non-parametric distributions, it is derived from data by estimating the coefficient of variation. Higher slopes indicate faster degradation, leading to narrower confidence intervals and lower RUL variance. The method’s applicability to stochastic processes and robustness under different data volumes are also investigated and discussed. The novel approach reveals heretofore unknown insights into classical reliability distributions. It is demonstrated through real-world applications, including LED reliability assessment, parallel system RUL estimation, and turbofan lifespan prediction using NASA N-CMAPSS data, offering a new perspective on the evolving dynamics of mean residual life and remaining useful life.

A survey on LED Prognostics and Health Management and uncertainty reduction Roberto Rocchetta, Elisa Perrone, Alexander Herzog, Pierre Dersin, Alessandro Di Bucchianico Microelectronics Reliability, 2024 Hybrid Prognostics and Health Management (PHM) frameworks for light-emitting diodes (LEDs) seek accurate remaining useful life (RUL) predictions by merging information from physics-of-failure laws with data-driven models and tools for online monitoring and data collection. Uncertainty quantification (UQ) and uncertainty reduction are essential to achieve accurate predictions and assess the effect of heterogeneous operational-environmental conditions, lack of data, and noises on LED durability. Aleatory uncertainty is considered in hybrid frameworks, and probabilistic models and predictions are applied to account for inherent variability and randomness in the LED lifetime. On the other hand, hybrid frameworks often neglect epistemic uncertainty, lacking formal characterization and reduction methods. In this survey, we propose an overview of accelerated data collection methods and modeling options for LEDs. In contrast to other works, this review focuses on uncertainty quantification and the fusion of hybrid PHM models with optimal design of experiment methods for epistemic uncertainty reduction. In particular, optimizing the data collection with a combination of statistical optimality criteria and accelerated degradation test schemes can substantially reduce the epistemic uncertainty and enhance the performance of hybrid prognostic models.
A Survey on Scenario Theory, Complexity, and Compression-Based Learning and Generalization Roberto Rocchetta, Alexander Mey, Frans A. Oliehoek IEEE Transactions on Neural Networks and Learning Systems, 2024 This work investigates formal generalization error bounds that apply to support vector machines (SVMs) in realizable and agnostic learning problems. We focus on recently observed parallels between probably approximately correct (PAC)-learning bounds, such as compression and complexity-based bounds, and novel error guarantees derived within scenario theory. Scenario theory provides nonasymptotic and distributional-free error bounds for models trained by solving data-driven decision-making problems. Relevant theorems and assumptions are reviewed and discussed. We propose a numerical comparison of the tightness and effectiveness of theoretical error bounds for support vector classifiers trained on several randomized experiments from 13 real-life problems. This analysis allows for a fair comparison of different approaches from both conceptual and experimental standpoints. Based on the numerical results, we argue that the error guarantees derived from scenario theory are often tighter for realizable problems and always yield informative results, i.e., probability bounds tighter than a vacuous [0, 1] interval. This work promotes scenario theory as an alternative tool for model selection, structural-risk minimization, and generalization error analysis of SVMs. In this way, we hope to bring the communities of scenario and statistical learning theory closer, so that they can benefit from each other's insights.
A BUSINESS MODEL OR A TARIFFING ISSUE? PEAK SHAVING IN LOCAL DISTRIBUTION GRIDS THROUGH ELECTRIC VEHICLE FLEETS Guntram Preßmair, Jakob Papouschek, Roberto Rocchetta Iet Conference Proceedings, 2024 This paper addresses the question how shared electric vehicle fleets, i.e. car-sharing or company fleets, can offer flexibility services for the electricity grid through smart and bidirectional charging. Specifically, the focus is on the perspective of DSOs, analysing the peak shaving potential at a common grid node. The paper provides initial insights from one of the case studies of the research project GAMES and demonstrates the economic potential under current and also possible future market designs for a station-based car sharing scheme in Zurich, Switzerland. The model deployed in this work is a linear economic dispatch model, providing optimal charging and discharging schedules for the electric vehicles of the fleet. The results suggest, that technically there could be the potential to reduce the annual peak load of the Zurich grid area by up to 4%. However, significant changes in the tariffing structure for charging peak loads need to be implemented to make business models for such use cases economically feasible.
Optimal Allocation and Sizing of Decentralized Solar Photovoltaic Generators Using Unit Financial Impact Indicator Ozcel Cangul, Roberto Rocchetta, Murat Fahrioglu, Edoardo Patelli Sustainability Switzerland, 2023 A novel financial metric denominated unit financial impact indicator (UFII) is proposed to minimize the payback period for solar photovoltaic (PV) systems investments and quantify the financial efficiency of allocation and sizing strategies. However, uncontrollable environmental conditions and operational uncertainties, such as variable power demands, component failures, and weather conditions, can threaten the robustness of the investment, and their effect needs to be accounted for. Therefore, a new probabilistic framework is proposed for the robust and optimal positioning and sizing of utility-scale PV systems in a transmission network. The probabilistic framework includes a new cloud intensity simulator to model solar photovoltaic power production based on historical data and quantified using an efficient Monte Carlo method. The optimized solution obtained using weighted sums of expected UFII and its variance is compared against those obtained by using well-established economic metrics from literature. The efficiency and usefulness of the proposed approach are tested on the 14-bus IEEE power grid case study. The results prove the applicability and efficacy of the new probabilistic metric to quantify the financial effectiveness of solar photovoltaic investments on different nodes and geographical regions in a power grid, considering the unavoidable conditional and operational uncertainty.
