In this study, an extended model of type (s, S) is considered and a semi-Markovian random
walk with Gaussian distribution of summands, which mathematically describes this model, is …

In this study, a renewal-reward process with a discrete interference of chance is constructed.
This process describes in particular a semi-Markovian inventory model of type (s, S). The …

In this study, the semi-Markovian random walk (X (t)) with a normal distribution of summands
and two barriers in the levels 0 and β> 0 is considered. Moreover, under some weak …

In this paper, the semi-Markovian random walk with two reflecting barriers is constructed
mathematically and non-stationary distribution functions of it are expressed by means of the …

In this paper, a semi-Markovian random walk process (X (t)) with a discrete interference of
chance is constructed and the ergodicity of this process is discussed. Some exact formulas …

In this study, a semi-Markovian random walk with a discrete interference of chance (X (t)) is
considered and under some weak assumptions the ergodicity of this process is discussed …

In this study, the semi-Markovian random walk with a special barrier (X (t)) is considered and
under some weak assumptions the ergodicity of this process is discussed. Moreover, the …

In this study, two boundary functionals 1 N and 1 τ of the renewal reward process with a
discrete interference of chance () t (X) are investigated. A relation between the moment …

In this study, a mechanical system with linear deterioration and preventive maintenance is
considered. The state of the system over time is represented by a semicontinuous stochastic …

Bu çalışmada,? Rasgele hacimli genişletilmiş (s, S) tipli modeller? denilen yarı-Markov bir
model ele alınmış ve bu modeli ifade eden stokastik süreç matematiksel …
