Reliability Modeling and Maintenance Optimization of Manufacturing System Based on Stochastic Flow Network and Markov Process

open access: yesShanghai Jiaotong Daxue xuebao, 2021
Aimed at the uncertainty of equipment quantity and input, the defective products and its rework in the manufacturing process are investigated. Considering the influence of the number or input of the devices on system reliability, a manufacturing system ...

Modeling stochastic gene expression: From Markov to non-Markov models

open access: yesMathematical Biosciences and Engineering, 2020
Gene expression is an inherently noisy process due to low copy numbers of mRNA or protein. The involved reaction events may happen in a Markov fashion but also in a non-Markov manner, depending on waiting-time distributions for the occurrence of reaction

Analysis of classical retrial queue with differentiated vacation and state dependent arrival rate.

open access: yesRatio Mathematica, 2021
In present paper we have introduced the concept of differentiated vacations in a retrial queueing model with state dependent arrival rates of customers. The arrival rate of customers is different in various states of the server.

Contribution to the Analysis of Non-Stationary Random Vibration of Vehicles

open access: yesCommunications, 2001
The goal of the paper is to include non-stationary random vibration excitation into the "classic" statistical solution of vehicles. Other vehicle parameters are the deterministic functions.

Phase transition for piecewise linear fibonacci bimodal map

open access: yesAIMS Mathematics, 2023
In this paper we concern with the Fibonacci bimodal maps. We first study the topological properties of the Fibonacci bimodal maps in the context of kneading map and give an equivalent description of Fibonacci combinatorics.

Quantum Semi-Markov Processes [PDF]

open access: yesPhysical Review Letters, 2008
We construct a large class of non-Markovian master equations that describe the dynamics of open quantum systems featuring strong memory effects, which relies on a quantum generalization of the concept of classical semi-Markov processes. General conditions for the complete positivity of the corresponding quantum dynamical maps are formulated.
