      Earthquake Forecasting Based on Multi-State System Methodology 

      Karagrigoriou, Alex; Makrides, Andreas; Tsapanos, T.; Vougiouka, G. (2016)
      This paper deals with earthquake long term predictions based on multi-state system methodology. As a reference we consider the South America case which was examined (Tsapanos, Bull Geol Soc Gr XXXIV/4:1611–1617, 2001) in ...

      Modeling and inference for multi-state systems 

      Barbu, Vlad Stefan; Karagrigoriou, Alex (2018)
      In this work we are focused on multi-state systems modeled by means of a special type of semi-Markov processes. The sojourn times are seen to be independent not necessarily identically distributed random variables and ...

      On semi-markov modelling and inference for multi-state systems 

      Barbu, Vlad Stefan; Karagrigoriou, Alex; Makrides, Andreas (Institute of Electrical and Electronics Engineers Inc., 2016)
      In this work we focus on multi state systems that we model by means of semi-Markov processes. The sojourn times are seen to be independent not identically distributed random variables and assumed to belong to a general ...

      Semi-Markov modelling for multi-state systems 

      Barbu, Vlad Stefan; Karagrigoriou, Alex; Makrides, Andreas (Institute of Electrical and Electronics Engineers Inc., 2014)
      Markov processes are widely used in reliability engineering. In this work we focus on multi state systems (MSS) and apply the Semi-Markov methodology for parameter estimation. For this purpose the sojourn times are assumed ...

      Statistical inference for multi-state systems: The weibull case 

      Makrides, Andreas; Karagrigoriou, Alex (2013)
      Markov processes are widely used for reliability analysis because the number of failures in arbitrary time intervals in many practical cases can be described as a Poisson process and the time up to the failure and repair ...
