DRILL BIT SELECTION IN A FORMATION WITH DIFFERENT SEDIMENTARY FACIES USING THE MARKOV CHAIN: A CASE STUDY AT ONE OF THE OIL FIELDS IN THE SOUTH OF IRAN

open access: yesRudarsko-geološko-naftni Zbornik, 2021
The selection of a drill bit is an essential issue in well planning. Furthermore, identification and evaluation of sedimentary rocks before well drilling plays a crucial role in choosing the drill bit.

Markov Tail Chains [PDF]

open access: yesJournal of Applied Probability, 2014
The extremes of a univariate Markov chain with regularly varying stationary marginal distribution and asymptotically linear behavior are known to exhibit a multiplicative random walk structure called the tail chain. In this paper we extend this fact to Markov chains with multivariate regularly varying marginal distributions in R

Markov chain based on neutrosophic numbers in decision making

open access: yesKuwait Journal of Science, 2021
Markov chain is a stochastic model for estimating the equilibrium of any system.  It is a unique mathematical model in which the future behavior of the system depends only on the present.

Using fuzzy time series with and without markov chain: to forecast of edible bird nest exported from Indonesia [PDF]

open access: yesE3S Web of Conferences, 2022
Edible bird nest (EBN) were traditional medicine consumed by the Tiongkok. This study compared two-algorithm method. Fuzzy time series and Markov chain as forecast method the number of bird nest exported from Indonesia.

Controlled Markov Chains

open access: yesThe Annals of Probability, 1975
We propose a control problem in which we minimize the expected hitting time of a fixed state in an arbitrary Markov chains with countable state space. A Markovian optimal strategy exists in all cases, and the value of this strategy is the unique solution of a nonlinear equation involving the transition function of the Markov chain.

Approximating Markov chains. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1992
A common framework of finite state approximating Markov chains is developed for discrete time deterministic and stochastic processes. Two types of approximating chains are introduced: (i) those based on stationary conditional probabilities (time averaging) and (ii) transient, based on the percentage of the Lebesgue measure of the image of cells ...

Prediksi Kurs Rupiah Terhadap Dolar Dengan FTS-Markov Chain Dan Hidden Markov Model

open access: yesJurnal Derivat, 2019
Hidden Markov model is a development of the Markov chain where the state cannot be observed directly (hidden), but can only be observed, a set of other observations and combination of fuzzy logic and Markov chain to predict Rupiah exchange rate against ...

Average-Based Fuzzy Time Series Markov Chain Based on Frequency Density Partitioning

open access: yesJournal of Applied Mathematics, 2023
Fuzzy time series (FTS) is one of the forecasting methods that has been developed until now. The fuzzy time series is a forecasting method that uses the concept of fuzzy logic, which Song and Chissom first introduced.

Polynomial Recurrence of Time-inhomogeneous Markov Chains

open access: yesAustrian Journal of Statistics, 2023
This paper is devoted to establishing conditions that guarantee the existence of a p-th moment of the time it takes for a timeinhomogeneous Markov chain to hit some set C.
