TLDR
In this article, a literature review is conducted to classify the articles on EWM applications in machining operations, which included 65 academic articles from different journals, books, and conferences since the year 2009.Abstract:
Machining operation optimization improves the quality of the product, reduces cost, enhances overall efficiency by reducing human error, and enables consistent and efficient operation. It is a vital decision-making process and achieves the best solution within constraints. It reduces reliance on machine-tool technicians and handbooks to identify cutting parameters, as a lack of awareness of the optimal combination of machining parameters leads to several machining inefficiencies. Subsequently, the optimization of the machining process is more useful for units of production, particularly machining units. In multi-objective optimization (MOO) problems, weights of importance are assigned, mostly identical. But, nowadays, the weights assignment techniques have received a lot of consideration from the professionals and researchers in MOO problems. Various techniques are developed to assign weights of significance to responses in MOO. The Entropy weights method (EWM) continues to work pleasingly across diverse machining operations to allocate objective weights. In this paper, a literature review is conducted to classify the articles on EWM applications in machining operations. The categorization proposal for the EWM reviews included 65 academic articles from different journals, books, and conferences since the year 2009. The EWM applications were separated into 18 categories of conventional and non-conventional machining operations. The implementation procedure of EWM is presented with an example along with method development. Scholarly articles in the EWM applications are further inferred based on (1) implementation of EWM in different machining operations, (2) MOO methods used with entropy weights in machining operations, (3) application of entropy weights by citation index and publication year, and (4) entropy weights applications in other fields. The review paper provided constructive insight into the EWM applications and ended with suggestions for further research in machining and different areas.read more

Analysis of wear and hardness during surface hardfacing of alloy steel by thermal spraying, electric arc and TIG welding
TL;DR: Hardfacing by welding is the most cost-effective technique to extend the life of parts that are exposed to the environment as discussed by the authors. Because of the rising expenses of repairing damaged/wear-out components, hardfacing is becoming more popular for manufacturing wearout components/tools used in the industry.

Exploring the impact of poverty on the Sustainable Development Goals: inhibiting synergies and magnifying trade-offs
TL;DR: Wang et al. as mentioned in this paper evaluated the synergies and trade-offs between SDGs by calculating the SDG Index and the Multidimensional Poverty Index, and they found that poverty hindered the achievement of most SDGs, and inhibition was heterogeneous among different SDGs and impoverished groups.

Methods for Multiple Attribute Decision Making
Ching-Lai Hwang,Kwangsun Yoon +1 more
TL;DR: There are some classical decision rules such as dominance, maximin and maximum which are still fit for the MADM environment but they do not require the DM’s preference information, and accordingly yield the objective (vs. subjective) solution.
