Abstract
Single-valued neutrosophic sets (SVNSs) and their application to material selection in engineering design. Liquid hydrogen is a feasible ingredient for energy storage in a lightweight application due to its high gravimetric power density. Material selection is an essential component in engineering since it meets all of the functional criteria of the object. Materials selection is a time-consuming as well as a critical phase in the design process. Inadequate material(s) selection can have a detrimental impact on a manufacturer’s production, profitability, and credibility. Multi-criteria decision-making (MCDM) is an important tool in the engineering design process that deals with complexities in material selection. However, the existing MCDM techniques often produce conflicting results. To address such problems, an innovative aggregation technique is proposed for material selection in engineering design based on truthness, indeterminacy, and falsity indexes of SVNSs. Taking advantage of SVNSs and smooth approximation with interactive Einstein operations, single-valued neutrosophic Einstein interactive weighted averaging and geometric operators are proposed. Based on proposed AOs, a robust MCDM approach is proposed for material selection in engineering design. A practical application of the proposed MCDM approach for material selection of cryogenic storage containers is developed. Additionally, the authenticity analysis and comparison analysis are designed to discuss the validity and rationality of the optimal decision.
Highlights
Problem resolution in our daily life is based on various stages like data collection, data analysis, information aggregation, etc
Material selection is an essential factor of the designing process money and resources can be squandered in the redesigning or fabrication of the planned part if the suitable material selection is not made during the designing process [3]
As the consequences of the structures grow by the day, it becomes increasingly difficult for the decision maker to make a reasonable judgement using unclear, erroneous, and imprecise facts in a reasonable period
Summary
Problem resolution in our daily life is based on various stages like data collection, data analysis, information aggregation, etc. Engineers and designers must consider a wide range of aspects when evaluating materials These material factors include thermal and radiation (conductivity, specific heat, diffusivity, expansively, reflectivity, transmissivity, emissivity), electrical (permittivity, resistivity, dielectric strength), surface (texture, wear-resisting, corrosivity), manufacturing properties (machinability, castability, weldability, formability, heat treatability, etc.), physical properties ( crystal structure, vapor pressure, density, melting point, porosity, permeability, transparency, dimensional stability, optical properties), magnetic properties, mechanical properties (strength, Young’s Modulus, elasticity, yield stress, creep resistance, fatigue, hardness and toughness, ductility), reliability, material cost, durability, fashion, material impact on the environment, recycle ability, aesthetics, market trends, availability, performance characteristics, cultural aspects, etc., [8,9,10,11].
