DOI: 10.1002/asmb.70039
Abstract: Repairable systems, crucial in reliability studies, are characterized by recurrent failure times modeled as counting processes with intensity functions. This paper explores models for these failure times incorporating imperfect repairs, addressing unobserved heterogeneity via shared… read more here.

DOI: 10.1007/s40430-016-0665-9
Abstract: This paper presents a quantitative reliability analysis method for repairable systems with two-input closed-loop feedback (TICLF) based on GO methodology. First, a new function operator, which is used to represent TICLF, is created and named… read more here.

DOI: 10.1080/00949655.2024.2381515
Abstract: In this paper, we propose a statistical model to describe the behaviour of failure times associated with groups of repairable systems hierarchically represented, under a competing risks framework, considering the existence of unobserved heterogeneity that… read more here.

DOI: 10.1109/access.2021.3077605
Abstract: The nonhomogeneous Poisson process (NHPP) has become a useful approach for modeling failure patterns of recurrent failure data revealed by minimal repairs from an individual repairable system. Sometimes, multiple repairable systems may present system-to-system variability… read more here.
