Croatian Operational Research Review, 2019 This paper concerns the cost optimisation analysis of a discrete-time finite-capacity multiserver queueing system with Bernoulli feedback, synchronous multiple and single working vacations, balking, and reneging during both busy and working vacation ...

Stochastic spatial models [PDF]
SIAM Review, 1999 The author considers a spatial model with the space represented as a grid of sites that can be in one of a finite number of states. The site changes its state with a rate that depends on states of a finite number of sites. Assuming that sites are independent, the behaviour of such models can be studied with the help of mean field ordinary differential ...

Combined Liouville–Caputo Fractional Differential Equation
Fractal and Fractional, 2023 This paper studies a fractional differential equation combined with a Liouville–Caputo fractional differential operator, namely, LCDηβ,γQ(t)=λϑ(t,Q(t)),t∈[c,d],β,γ∈(0,1],η∈[0,1], where Q(c)=qc is a bounded and non-negative initial value.

An Insight into the Potassium Currents of hERG and Their Simulation
Molecules, 2023 By assuming that a stepwise outward movement of the four S4 segments of the hERG potassium channel determines a concomitant progressive increase in the flow of the permeant potassium ions, the inward and outward potassium currents can be simulated by ...

A Stochastic Approach for Product Costing in Manufacturing Processes
Mathematics, 2021 Nowadays, manufacturing companies are characterized by complex systems with multiple products being manufactured in multiple assembly lines. In such situations, traditional costing systems based on deterministic cost models cannot be used.

The Annals of Probability, 1999 We study an ordinary differential equation controlled by a stochastic process. We present results on existence and uniqueness of solutions, on associated local times (Trotter and Ray-Knight theorems), and on time and direction of bifurcation. A relationship with Lipschitz approximations to Brownian paths is also discussed.

A Markovian batch arrival queueing system with disasters, working breakdowns, and impatience: Mathematical modeling and economic analysis [PDF]
Yugoslav Journal of Operations ResearchMachining systems are essential for many industrial applications, such as manufacturing, processing, and assembly. However, these systems are often exposed to various sources of uncertainty and disruption, such as disasters and customer impatience. These

Dynamic Behavior of a Stochastic Amensalism Population Model
Journal of Harbin University of Science and Technology, 2022 Aiming at the problem of biased symbiosis dynamics affected by environmental factors, according to the theory of stochastic differential equation, the stochastic biased symbiosis dynamics model is established by introducing white noise, and the dynamic ...

Stochastic Frontier Models [PDF]
, 2008 The stochastic frontier model was first proposed in the context of production function estimation to account for the effect of technical inefficiency. The inefficiency causes actual output to fall below the potential level (that is, the production frontier) and also raises production cost above the minimum level (that is, the cost frontier).

Almost Periodic Solutions for Impulsive Fractional Stochastic Evolution Equations
International Journal of Analysis and Applications, 2014 In this paper, we consider the existence of square-mean piecewise almost periodic solutions for impulsive fractional stochastic evolution equations involving Caputo fractional derivative.
