Mehdi Shams; Gholamreza Hesamian

Volume 55, Issue 1 , June 2023, , Pages 53-65

Abstract
  A random walk is a special kind of stochastic process of the Markov chain type. Some stochastic processes can be represented as a random walk on a graph. In this paper, the main parameters for a random walk on graph are examined.  Read More

Fuzzy Cumulative Distribution Function and its Properties }

Gholamreza Hesamian; Mehdi Shams

Volume 53, Issue 2 , December 2021, , Pages 75-84

https://doi.org/10.22059/jac.2021.85245

Abstract
  The statistical methods based on cumulative distribution function is a start point for  many parametric or nonparametric statistical inferences. However, there are many practical problems that require dealing with observations/parameters that represent inherently imprecise.  However, Hesamian ...  Read More

Correlation Coefficients for Hesitant Fuzzy Linguistic Term Sets

Gholamreza Hesamian; Mohammad Ghasem Akbari

Volume 51, Issue 1 , June 2019, , Pages 79-89

https://doi.org/10.22059/jac.2019.71533

Abstract
  Here are many situations in real applications of decision making where we deal with uncertain conditions.  Due to the different sources of uncertainty,  since its original definition of fuzzy sets in 1965 \cite{zadeh1965},  different generalizations and extensions of fuzzy sets have been ...  Read More

Sign Test for Fuzzy Random Variables

Mehdi Shams; Gholamreza Hesamian

Volume 50, issue 2 , December 2018, , Pages 121-139

https://doi.org/10.22059/jac.2018.70450

Abstract
  This paper extends the sign test to the case where data are observations of fuzzy random variables, and the hypotheses are imprecise rather than crisp. In this approach, first a new notion of fuzzy random variables is introduced. Then, the $\alpha$-level sets of the imprecise observations are transacted ...  Read More
