Abstract

The unique area of friction stir welding that involves Al-TiB2 composite development stirs controversy and fails to offer a clear understanding of how to choose the best composite among alternatives without subjectivity. At present, the experienced fabricator uses intuition in judgement, leading to wrong or inconsistent decisions. In this paper, the WASPAS multicriteria model is deployed to choose the best Al-TiB2 composite among options using tensile strength, ductility and microhardness as attributes. The procedure generally entails normalization, preference score and ranking determination and literature data was used. The emerging conclusion from this study is that irrespective of the weight determination method and the multicriteria model adopted to evaluate the alternative fabricated Al-TiB2 composites, the Al-10%TiB2 and Al6065 based alloy always reveal as the best and worst composites, respectively, even under varied normalisation methods. The research confirmed that multicriteria analysis is a potential objective method to choose among fabricated alternatives. The work showed that there is scope to evade the consequences of subjectivity in composite decision making by attaching adequate weights to the deciding factors thereby avoiding misguidance and incorrect decision making. Furthermore, multicriteria models offer novel approaches to understand the relative preference of fabricating composites to one another in the metal matrix composite development area.

Abstract

This paper presents the research conducted on three tradesmen, the mechanics, carpenters, and welders, to measure and compare the left and right hands' dimensions and evaluate the hand index to understand the measurements. Despite rea's utility, the area's utility research has analyzed these technical personnel's hand characteristics. Compared with manufacturing systems, small businesses and entrepreneurs are loss studied. Still, opportunities abound to recognize, appraise, and explore novel instances associated with new product development with detailed information on their hand measurements. Data was collected from mechanics, carpenters, and welders rating in Lagos, Nigeria. The analysis is divided into hand measurements, finger measurements, hand index of the mechanics, carpenters, and welders. The subjects ranged between 18 and 60 years, and measures were made while the subject stands erect. Vernier caliper and tape rules were made. Data concerning heights, hand's height and width, and other aspects of the hand were collected. It was observed that the carpenters have higher values of the hand length to the right third finger. By comparing the mechanics and welders, the mechanics have higher values throughout the experiment. The subjects' heights for carpenters have the highest values. The right and left-hand dimensions are close for the mechanics. There is a greater deviation for the left and right hand for the welders. The deviation is also observed for the carpenters.
