Hesitant Fuzzy-Stochastic Data Envelopment Analysis (HF-SDEA) Model for Benchmarking

open access: yesJOIV: International Journal on Informatics Visualization, 2021
The Data Envelopment Analysis (DEA) method is a method commonly used in benchmarking. The Dynamic Data Envelopment Analysis (DDEA) method was proposed to improve the DEA method in the benchmarking process.

A reliable numerical analysis for stochastic dengue epidemic model with incubation period of virus

open access: yesAdvances in Difference Equations, 2019
This article represents a numerical analysis for a stochastic dengue epidemic model with incubation period of virus. We discuss the comparison of solutions between the stochastic dengue model and a deterministic dengue model. In this paper, we have shown

Efficiency of the stochastic approximation method [PDF]

open access: yesYugoslav Journal of Operations Research, 2012
The practical aspect of the stochastic approximation method (SA) is studied. Specifically, we investigated the efficiency depending on the coefficients that generate the step length in optimization algorithm, as well as the efficiency depending on the

A New Stochastic Model Updating Method Based on Improved Cross-Model Cross-Mode Technique

open access: yesSensors, 2021
This paper proposes a new stochastic model updating method to update structural models based on the improved cross-model cross-mode (ICMCM) technique. This new method combines the stochastic hybrid perturbation-Galerkin method with the ICMCM method to ...

Stochastic Material Point Method for Analysis in Non-Linear Dynamics of Metals

open access: yesMetals, 2019
A stochastic material point method is proposed for stochastic analysis in non-linear dynamics of metals with varying random material properties. The basic random variables are parameters of equation of state and those of constitutive equation.

PRACTICAL STOCHASTIC MODEL FOR CHEMICAL KINETICS

open access: yesQuímica Nova, 2015
The Practical Stochastic Model is a simple and robust method to describe coupled chemical reactions. The connection between this stochastic method and a deterministic method was initially established to understand how the parameters and variables that ...

A constrained stochastic state selection method applied to quantum spin systems

open access: yes, 2009
We describe a further development of the stochastic state selection method, which is a kind of Monte Carlo method we have proposed in order to numerically study large quantum spin systems. In the stochastic state selection method we make a sampling which
