Modelling Stochastic Inflow Patterns to a Reservoir with a Hidden Phase-Type Markov Model
M. L. Gamiz, D. Montoro, M. C Segovia-Garcia
This paper presents a novel methodology for modelling precipitation patterns in a specific geographical region using Hidden Markov Models (HMMs). Departing from conventional HMMs,…
Towards the Best Solution for Complex System Reliability: Can Statistics Outperform Machine Learning?
Maria Luz Gamiz, Fernando Navas-Gomez, Rafael Nozal-Cañadas +1
Studying the reliability of complex systems using machine learning techniques involves facing a series of technical and practical challenges, ranging from the intrinsic nature of t…
A Hierarchical Decision-Based Maintenance for a Complex Modular System Driven by the { MoMA} Algorithm
M. L. Gamiz, D. Montoro-Cazorla, M. C. Segovia-Garcia
This paper presents a maintenance policy for a modular system formed by K independent modules (n-subsystems) subjected to environmental conditions (shocks). For the modeling of thi…
Multiplicative local linear hazard estimation and best one-sided cross-validation
Maria Luz Gamiz, Maria Dolores Martinez-Miranda, Jens Perch Nielsen
This paper develops detailed mathematical statistical theory of a new class of cross-validation techniques of local linear kernel hazards and their multiplicative bias corrections.…
