MMAPs to model complex multi-state systems with vacation policies in the repair facility

Juan Eloy Ruiz-Castro, Christian Acal

Two complex multi-state systems subject to multiple events are built in an algorithmic and computational way by considering phase-type distributions and Markovian arrival processes…

One cut-point phase-type distributions in Reliability. An application to Resistive Random Access Memories

Christian Acal, Juan Eloy Ruiz-Castro, David Maldonado +1

A new probability distribution to study lifetime data in reliability is introduced in this paper. This one is a first approach to a non-homogeneous phase-type distribution. It is b…

An approach to non-homogenous phase-type distributions through multiple cut-points

Juan Eloy Ruiz-Castro, Christian Acal, Juan B. Roldán

A new class of distributions based on phase-type distributions is introduced in the current paper to model lifetime data in the field of reliability analysis. This one is the natur…

A shiny app for modeling the lifetime in primary breast cancer patients through phase-type distributions

Christian Acal, Elena Contreras, Ismael Montero +1

Phase-type distributions (PHDs), which are defined as the distribution of the lifetime up to the absorption in an absorbent Markov chain, are an appropriate candidate to model the…

Different PCA approaches for vector functional time series with applications to resistive switching processes

C. Acal, A. M. Aguilera, F. J. Alonso +2

This paper is motivated by modeling the cycle-to-cycle variability associated with the resistive switching operation behind memristors. As the data are by nature curves, functional…
