A Versatile Queuing System For Sharing Economy Platform Operations
Mathematics, 2019 The paper deals with a sharing economy system with various management factors by using a bulk input G/M/1 type queuing model. The effective management of operating costs is vital for controlling the sharing economy platform and this research builds the ...

On Semi-Markov and Semiregenerative Processes II
The Annals of Probability, 1978 An ergodic theorem is given for the age process $(I(t), Z(t))$ associated with a (possibly transient) semi-Markov chain $(I_n, X_n)^\infty_{n=0}$ whose sojourn times are not exclusively integer valued. Asymptotically the Markov part $(I(t):$ the state occupied at time $t)$ and the renewal part $(Z(t):$ the age in $I(t)$ at time $t)$ split into ...

Exact formulas for the moments of the first passage time of reward processes
Revstat Statistical Journal, 2005 Let {Zρ(t), t ≥ 0} be a reward process based on a semi-Markov process {J (t), t ≥ 0} and a reward function ρ. Let Tz be the first passage time of {Zρ(t), t ≥ 0} from Zρ(0) = 0 to a prespecified level z.

From Risk Assessment to Resilience Assessment. an Application to a Hazmat Storage Plant
Chemical Engineering Transactions, 2020 The purpose of this work is to outline a framework for assessing the resilience of a petrochemical storage plant, through the construction of a dynamic hierarchical Bayesian network. The BN approach allows keeping memory of the states, in order to manage

International Journal of Mathematics and Mathematical Sciences, 1992 This paper introduces a bulk queueing system with a single server processing groups of customers of a variable size. If upon completion of service the queueing level is at least r the server takes a batch of size r and processes it a random time ...

A Novel Analytical Model for Network-on-Chip using Semi-Markov Process
Advances in Electrical and Computer Engineering, 2011 Network-on-Chip (NoC) communication architecture is proposed to resolve the bottleneck of Multi-processor communication in a single chip. In this paper, a performance analytical model using Semi-Markov Process (SMP) is presented to obtain the NoC ...

Comparison of Semi-Markov and Markov Processes
The Annals of Mathematical Statistics, 1971 Conditions are given under which a semi-Markov process $Z(t)$ can be obtained from a Markov process $Y(t)$ by a time change (i.e. $Z(t) = Y(\gamma(t))$). Estimates are given for $P\{\sup_{s\leqq t} |s - \gamma(s)| > \varepsilon\}$ and the construction is used to give conditions under which a sequence of semi-Markov processes will have the same ...

Metastable distributions of semi-Markov processes
Stochastics and DynamicsIn this paper, we consider semi-Markov processes whose transition times and transition probabilities depend on a small parameter [Formula: see text]. We are interested in the behavior of a process [Formula: see text] at times [Formula: see text] that depend on the value of the parameter.

Credit Risk Assessment Using Fuzzy Inhomogeneous Markov Chains Within a Fuzzy Market
RisksIn the present study, we model the migration process and the changes in the market environment. The migration process is being modeled as an F-inhomogeneous semi-Markov process with fuzzy states.
