Two competing paradigms to modelling the impacts of regional economic shocks have arisen: ‘disequilibrium’ models, which predict that economies eventually fully recover, and ‘no-equilibriu...

The paper introduces a novel approach to ensemble modeling as weighted model average technique. proposed idea is prudent, simple understand, and easy implement compared the Bayesian frequentist approach. provides both theoretical empirical contributions for assessing credit risk (probability of default) effectively in new way by creating an linear combination machine learning models. can be gen...

We develop a new decision making model based on the use of a unified approach between the probability, the weighted average and the ordered weighted averaging (OWA) operator in an uncertain environment that can be assessed with fuzzy numbers (FNs). We present a new aggregation operator called the fuzzy probabilistic ordered weighted averaging – weighted averaging (FPOWAWA) operator. We study it...

examination of demand of money and recognition of important factors, is one of the important problems in macroeconomic. identifying important factors that can affect demand money function, beside other economic factors, guaranty successfulness for economic policies. semblance of many studies have been carried out to specify factors affecting demand of money, indicate some scattering on choosing...

A new approach to defining the effective fracture toughness for heterogeneous materials is proposed. This temporal averaging process dependent, incorporating crack velocity and material toughness. The effectiveness of technique investigated in context hydraulic through rock with a periodic plane strain model considered without fluid leak-off, more easily investigate different regimes (toughness...

In this paper we present two new types aggregation operators such as, induced Pythagorean fuzzy ordered weighted averaging aggregation operator and induced Pythagorean fuzzy hybrid averaging aggregation operator. We also discuss of important properties of these proposed operators and construct some examples to develop these operators.
