Erratum to: A mathematical model for solving fully fuzzy linear programming problem with trapezoidal fuzzy numbers (Appl Intell, (2016), 10.1007/s10489-016-0779-x)

Abstract

Das et al [1] proposed a method for solving fully fuzzy linear programming (FFLP) problems in which all the parameters and variables are represented by non-negative trapezoidal fuzzy numbers. However, inadvertently to illustrate the proposed method as well as to show the advantages of the proposed method, Das et al. considered such FFLP problems in which some or all the variables are unrestricted trapezoidal fuzzy numbers. The proposed method can be used only for solving such FFLP problems in which all the decision variables are non-negative fuzzy numbers. Also, the authors of the paper [1] did not give due credit to the papers [2] and [3]. References 1.
