Abstract: In this paper, a new approach for solving fuzzy capacitated location problems is proposed. Both the capacity and the demand constraints are considered fuzzy while the objective function is not. A membership function is defined for the non-fuzzy objective function to convert it to a fuzzy one. The α- cut is used for the membership functions. The max-min approach is utilised within the proposed method. The models which are in the form of mixed zero-one nonlinear programs are transformed to their equivalent linear ones. Four mixed zero-one linear programs are required to be sequentially solved. The solution of the fourth program represents the ultimate optimal solution of the problem. The suggested approach is illustrated by a numerical example.

Keywords: fuzzy programming; fuzzy capacitated location problem; max-min approach; Chang's linearisation approach; mixed zero-one programs. (search for similar items in EconPapers)
