Linear neutrosophic pentadecagonal fuzzy number with symmetry in solving fuzzy environmental problems

Abstract In this paper, we deal with the new concept of linear Pentadecagonal neutrosophic fuzzy number with symmetry. Neutrosophic number are extensively used by researchers where unclear, uncertain information appear, so this paper focus on its properties using alpha cut method. We had applied it in a real life problem and found the result using the assignment problem. So alpha cut method is introduced.
