Trillas et al. (1999, Soft computing, 3 (4), 197-199) and Trillas and Cubillo (1999, On non-contradictory input/output couples in Zadeh's CRI proceeding, 28-32) introduced the study of contradiction in the framework of fuzzy logic because of the significance of avoiding contradictory outputs in inference processes. Later, the study of contradiction in the framework of Atanassov' s intuitionisti...

Moreover, Zhu et al. [11], developed dual hesitant fuzzy sets (DHFSs) as a new extension of HFSs. The DHFS is a comprehensive set encompassing several existing fuzzy sets with certain conditions, whose membership and nonmembership are represented by a set of possible values respectively. In particular cases, DHFSs can reduce to some existing fuzzy sets, such as FSs, IFSs, HFSs and FMSs. From a ...

Iterated Function Systems (IFSs) are among the best-known methods for constructing fractals. The sequence of pictures E0; E1; E2; : : : generated by an IFS fX; f1; f2; : : : ; ftg converges to a unique limit E , which is independent of the choice of starting set E0, but completely determined by the choice of the maps fi. Random context picture grammars (rcpgs) are a method of syntactic picture ...

In the fuzzy set theory, information  measures play a paramount role in several areas such as decision making, pattern recognition etc. In this paper, similarity measure based on cosine function and entropy measures based on logarithmic function for IFSs are proposed. Comparisons of proposed similarity and entropy measures with the existing ones are listed. Numerical results limpidly betoken th...

One of the main issues with Carbon Fiber Reinforced Thermoplastics (CFRTP) is poor impregnation quality matrix on carbon fiber due to high viscosity thermoplastic. Impregnation can significantly affect mechanical properties composite. This study aims compare abilities various types thermoplastic matrices fiber. The used in this are HDPE, PC, and PET. Three variations treatment were employed: fi...

Interface optimisation for continuous hemp reinforcements in epoxy resin is a current challenge the development of biocomposites. A chemical treatment based on hydrogen peroxide and physical one using non-thermal plasma have been tested to optimise interface adhesion, by varying several parameters. FTIR analysis FE-SEM observations shown effects treatments morphological aspects treated yarns. T...

The design of the packages products/services to be offered by a telecom company its clients is complex decision-making process that must consider different criteria achieve both customer satisfaction and optimization company’s resources. In this process, Intuitionistic Fuzzy Sets (IFSs) can used manage uncertainty better represent preferences non-preferences expressed people who value each prop...

Multi-attribute decision-making (MADM) is usually used to aggregate fuzzy data successfully. Choosing the best option regarding not generally symmetric on grounds that it does provide complete information. Since Aczel-Alsina aggregation operators (AOs) have great impact due their parameter variableness, they been well applied in MADM under construction. Recently, AOs intuitionistic sets (IFSs),...

Intuitionistic fuzzy sets (IFSs) are key concepts in ambiguity and uncertainty. However, IFSs deal only with anticipation, not periodicity. To do so, complex intuitionistic (CIFS) can handle uncertainties periodicity simultaneously. Also, the Maclaurin symmetric mean (MSM) operator is a better tool for dealing criteria’s interrelationships. As result, this article presents multi-criteria decisi...
