A method based on grey relational analysis and D-S theory of evidence is proposed for fuzzy soft sets in decision making. Firstly, grey relational analysis is used to calculate grey mean relational degrees and determine uncertain degrees of parameters. Then based on uncertain degrees, suitable mass functions of different independent alternatives with different parameters can be constructed. Nex...

Grey relational analyses are applied to determine the suitable selection of machining parameters for Wire Electrical Discharge Machining (Wire-EDM) process. The Grey theory can provide a solution of a system in which the model is unsure or the information is incomplete. Besides, it provides an efficient solution to the uncertainty, multi-input and discrete data problem. According to the Taguchi...

The theory instrument of grey relational analysis is grey relational grade between the sequences. The grey relational grade is a measure of the degree of association between two factors, or between two systems. It describes the relative changes among the various factors in the development process of the system. In turn, we can calculate the grey relational grade, compare and judge the grey rela...

The core objective of the integrated curriculum of compulsory education is to “enable students to demonstrate their network-talents instead of just scoring high on independent exams.” The key to determining education reform strategies in the e-era is to establish network-competence indicators for educational behavior in primary schools. We propose a MCDM means for evaluating, comparing and impr...

CNC turning is widely used as a manufacturing process through which unwanted material is removed to get the high degree of surface rough. In this research article, Taguchi technique was coupled with grey relation analysis (GRA) to optimize the turning parameters for simultaneous improvement of productivity, average surface roughness (Ra), and root mean square roughness (Rq).Taguchi technique L2...

One of the most former and widely utilized unconventional machining is known as process electric discharge (EDM). This a procedure, where serialized set discharges are applied to eliminate material from workpiece (i.e., electrically conductive). article proposes bi-objective optimization arguments in stainless steel 630 (SS630) grade using both experimentation thermal investigation. Here, flush...

Micro-EDM (Electro Discharge Machining) is widely used for precision manufacturing and drilling micro-holes in materials fuel nozzles, micro sensors robots, surgical instruments, turbines etc. Present paper deals with common C360 brass components by micro-machining optimizing the process parameter using a hybrid approach of design experiments (DoE) grey relation analysis (GRA) concept. The thre...

Southern right whales (SRWs, Eubalena australis) are polymorphic for an X-linked pigmentation pattern known as grey morphism. Most SRWs have completely black skin with white patches on their bellies and occasionally on their backs; these patches remain white as the whale ages. Grey morphs (previously referred to as partial albinos) appear mostly white at birth, with a splattering of rounded bla...
