On d*-Complete Topological Spaces and Related Fixed Point Results
(MDPI, Basel, 2020)
In this paper, we introduce the concept ofd*-complete topological spaces, which include earlier defined classes of complete metric spaces and quasib-metric spaces. Further, we prove some fixed point results for mappings ...
Evaluation and Selection of the Quality Methods for Manufacturing Process Reliability Improvement-Intuitionistic Fuzzy Sets and Genetic Algorithm Approach
(MDPI, Basel, 2021)
The aim of this research is to propose a hybrid decision-making model for evaluation and selection of quality methods whose application leads to improved reliability of manufacturing in the process industry. Evaluation of ...
Fixed Points on Covariant and Contravariant Maps with an Application
(MDPI, 2022)
Fixed-point results on covariant maps and contravariant maps in a (Formula presented.) -algebra-valued bipolar metric space are proved. Our results generalize and extend some recently obtained results in the existing ...
Analysis of the Dynamic Response as a Basis for the Efficient Protection of Large Structure Health Using Controllable Frequency-Controlled Drives
(MDPI (Basel, Switzerland), 2023)
Continuous earthmoving machines, such as bucket-wheel excavators (BWEs), are the largest mobile terrestrial machines exposed to the working loads of a periodic character. This paper aims to launch a new idea regarding the ...
The Results on Coincidence and Common Fixed Points for a New Type Multivalued Mappings in b-Metric Spaces
(MDPI, Basel, 2022)
In this paper, we obtain the results of coincidence and common fixed points in b-metric spaces. We work with a new type of multivalued quasi-contractive mapping with nonlinear comparison functions. Our results generalize ...
Risk Evaluation: Brief Review and Innovation Model Based on Fuzzy Logic and MCDM
(MDPI, Basel, 2022)
The risk assessment of engineering systems represents an important part of the quality of service and dependability. The existing methods for risk evaluation use crisp sets for rating partial indicators' proposition and ...
Determining the Risk Level in Client Analysis by Applying Fuzzy Logic in Insurance Sector
(MDPI, 2022)
The aim of the paper is to determine the risk level of a contract extension with the existing policyholders, which is further propagated to the business effectiveness and long-term sustainability of the company. The ...
