The present research used the stir-casting method to develop an Al-based composite. developed composite exhibited challenges while being processed on conventional machining. Thus, a non-traditional machining process was opted variables selected for current were pulse off time (Toff), (Ton), servo voltage (SV), (I), and tool electrode. Three electrodes (SS-304, copper, brass) (Al/SiC/Gr). experi...

Recent research is recognizing that multiple criteria analysis should take account of the concepts of uncertainty and risk. In some cases, precise determination of the exact value of alternatives and weights of criteria is difficult. Consequently, to deal with these potential problems, their values are regarded as fuzzy and intervals. This paper proposes an interval-valued fuzzy multiple criter...

The variability in customer demands necessitates careful monitoring of production processes. At this point, supplier selection, which is the first and most important stage production, gains importance. However, selection problem affected by many criteria with different weights depending on area. In addition, today's intense competition, such problems are too to be left intuition parties. case, ...

Computer mining rigs are specially designed for only one purpose which is to mine crypto assets efficiently and effectively. Mining takes a lot of time, therefore it very important pay attentionto computers mining. The better the quality PC or computer, faster processwill be. So far, consumers in choosing rig computer observe computerwithout looking at special criteria such as price, motherboar...

This study aims to present a multi-criteria decision analysis (MCDA) for comprehensive performance evaluation of the alternative design timber–concrete composite (TCC) floor system. Considered objectives are serviceability and sustainability with associated criterion as (1) comfort class regarding springiness vibrations, (2) architectural quality open spaces, (3) environmental aspect CO2 emissi...
