In this article, we propose a method based on new ranking technique to find optimal solution for pentagonal fuzzy transportation problem. Firstly, the proposed which is centroid concept applied. This transforms problem crisp and then algorithm applied of in form. Also, initial basic feasible (IBFS) valued problems introduced paper. Further, give two numerical illustrations newly compare obtaine...
