      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 ...
