In this study, a naturally sourced cutting oil mixture using for the magnetorheological finishing (MRF) as an environmentally friendly carrier liquid. addition, fuzzy grey relation analysis has been developed to predict and give optimal parameters, main factors affecting surface quality material removal rate (MRR) identified. Experimental polishing procedures Ti-6Al-4V alloy were performed conf...

This research applied Fuzzy Delphi Analytic Hierarchy Process (FDAHP) to evaluate the critical success factors for New Product Development (NPD) by using a hybrid vehicle as an example. Grey Relational Analysis (GRA) is used to assess the level of gray relation among these factors, followed by empirical analysis to construct the NPD strategy. The empirical result illustrates that the indicators...

Reinforced concrete (RC) column is an important load-bearing component in building structures. In order to study the blast resistance of RC columns, numerical simulation model was verified based on field test data, and ANSYS/LS-DYNA 2020R2 software used expand working conditions. The sensitivity analysis method grey relation degree effects factors, such as diameter longitudinal reinforcement, n...

The prediction of concrete strength is an interesting point investigation and could be realized well, especially for the with complex system, development machine learning artificial intelligence. Therefore, excellent algorithm should put emphasis to receiving increased attention from researchers. This study presents a novel predictive system as follows: extreme gradient boosting (XGBoost) based...

due to the importance of “service quality and customerssatisfaction” subject, this study seeks to investigate and prioritize thefactors which are effective on service quality and customers satisfactionusing grey relational analysis (gra) method. in the case of statisticalpopulations with large sizes, none of the other methods can competewith gra from the viewpoint of calculation accuracy. the s...

In multiple sclerosis (MS), diffuse degenerative processes in the deep grey matter have been associated with clinical disabilities. We performed a systematic study in MS deep grey matter with a focus on the incidence and topographical distribution of lesions in relation to white matter and cortex in a total sample of 75 MS autopsy patients and 12 controls. In addition, detailed analyses of infl...

Considering the concept of clustering, the main idea of the present study is based on the fact that all stocks for choosing and ranking will not be necessarily in one cluster. Taking the mentioned point into account, this study aims at offering a new methodology for making decisions concerning the formation of a portfolio of stocks in the stock market. To meet this end, Multiple-Criteria Decisi...
