Numerical solution of fuzzy non-linear equations under generalized trapezoidal fuzziness by Newton–Raphson method

open access: yesFranklin Open
In the real world, we are faced with many problems that cannot be easily described by crisp values, as there is always some uncertainty involved in real-life situations and in those situations, we end up receiving fuzzy values rather than crisp ones in ...
