“…Atanassov (1994) proposed intuitionistic fuzzy sets (IFSs), which consider both the degrees of the elements but fail when the total sum turns out to be more than 1. The Pythagorean fuzzy sets (PFSs) are based on Pythagorean negation allowing for a larger space for imprecise memberships (Wu et al, 2019;Yadav & Chawla 2022a, 2022bGupta et al, 2022) 1.5 TODIM Method TODIM (an acronym for "Tomada de Decisão Interativa e Multicritério" in Portuguese, which translates to Interactive and Multicriteria Decision Making) is a method used in MCDM to support decision-making when there are multiple criteria and alternatives to consider. The TODIM method is based on prospect theory.…”

This paper aims to improve the ABC analysis method used for inventory management by applying the Pythagorean Fuzzy TODIM approach. ABC analysis is one the well-known and widely used inventory classification techniques which divides inventory items into three categories according to their importance and value. However, the traditional ABC analysis does not consider the imprecision and vagueness of real-world inventory data, which can lead to inaccurate results and poor inventory management decisions. The proposed approach enhances the traditional ABC analysis by incorporating fuzzy numbers to be considered in real-world inventory data. The improved ABC analysis helps companies to optimize inventory levels, reduce costs, improve customer service, and increase overall operational efficiency. To check for the reliability and effectiveness of the developed model under different scenarios sensitivity analysis is conducted. Additionally, the comparative analysis among other existing models further demonstrates the model's accuracy. The model prepared shows that the Pythagorean Fuzzy TODIM approach is superior to the conventional ABC analysis in terms of reliability and dealing with the uncertain inventory data. Overall, this paper provides a novel and effective approach to inventory management and offers valuable insights for practitioners and researchers in the field.

“…Some fibers like hemp, pineapple, sisal, and kenaf show similar properties compared to steel and aluminum [6,[57][58][59][60][61]. Because of the innumerable and positive characteristics of natural fibers, the utilization of composites made by these fibers shows their wide range of uses in areas of vehicle, construction, aircraft, and marine industries [7][8][9][10][11][62][63][64][65][66][67][68]. Despite these numerous pros of NFCs, some cons need to be observed, such as low impact strength, high rate of water absorption, and lower heating capacity.…”

The manufacturing sector is presently in search of sustainable materials that are lighter in weight, readily available, biodegradable, and cost-friendly. Natural fibers are observed to bring unblemished advancement in composite materials. In this research, a novel hybrid composite material has been analyzed. The composite comprises two different natural fibers, kenaf and coir fiber, reinforced in epoxy matrix with nanofillers of calcium carbonate particles. The weight percent of kenaf and coir fibers is maintained at 5.7% and 10%, whereas nanofillers is varied as 0%, 2%, and 4%, respectively, in all three samples. The elastic characteristics like the Longitudinal Modulus, and Transverse Modulus, are evaluated for the proposed composite utilizing five different analytical models, and are also interpreted using Representative Volume Element (RVE) analysis. The analytical results of the proposed composite are correlated with the experimental work in the earlier research. The influence of nanofiller is investigated and it has been observed that the composite with a higher filler content of 4 percent attains enhanced strength than a sample with a lower filler content of 0 and 2 wt. percent. The transverse modulus is noticed to uplift by 16.88%, and the longitudinal modulus by 11.14% on the mixing of CaCO3 particles in coir kenaf composite. Also, the composite is analyzed for hybridization effect, which proves to be one of the most promising ways to improve the features of the hybrid composite
