Fuzzy Sets Type

This section provides comprehensive documentation for the specialized fuzzy set types implemented in AxisFuzzy, focusing on advanced mathematical frameworks that extend traditional fuzzy logic capabilities. These sophisticated fuzzy set types enable researchers and practitioners to model complex uncertainty scenarios with enhanced precision and flexibility.

The documentation covers four primary categories of fuzzy sets, ranging from classical foundational types to advanced hesitant fuzzy structures. Each type addresses specific uncertainty modeling requirements and provides unique computational advantages for different application domains.

Classical Fuzzy Sets (FS) represent the foundational framework introduced by Lotfi A. Zadeh, providing the theoretical basis for all fuzzy logic systems. These sets model uncertainty through single membership degrees and serve as the computational foundation for more complex fuzzy types.

Q-Rung Orthopair Fuzzy Numbers (QROFN) extend classical fuzzy sets by introducing non-membership degrees with parameterized constraints, enabling more flexible uncertainty representation through the q-rung parameter that controls the relationship between membership and non-membership assessments.

Interval-Valued Q-Rung Orthopair Fuzzy Numbers (IVQROFN) further enhance this framework by representing both membership and non-membership degrees as intervals rather than point values, enabling the modeling of uncertainty in the precision of fuzzy assessments themselves.

Q-Rung Orthopair Hesitant Fuzzy Numbers (QROHFN) incorporate hesitation elements into the q-rung framework, allowing decision-makers to express multiple possible membership and non-membership values simultaneously, particularly valuable in group decision-making scenarios where consensus may be difficult to achieve.

Each fuzzy type includes detailed mathematical definitions, implementation guidelines, practical examples, and integration methods with AxisFuzzy’s core functionality.
