A note on “Parallel variable neighborhood search for solving fuzzy multi-objective dynamic facility layout problem”

Abstract

Abedzadeh et al. (Int J Adv Manuf Technol 65:197-211, 2013) proposed a mixed integer programming formulation for dynamic flexible bay layout problem with three objectives: minimizing material handling and relayout cost, maximizing adjacency ratio, and minimizing shape ratio difference. In this paper, we correct the formulation proposed by Abedzadeh et al. (Int J Adv Manuf Technol 65:197-211, 2013). This correction is mainly focused on the three objectives of their formulation. It is shown that the relayout cost was miscalculated, the adjacency ratio was improperly linearized, the third objective was incorrectly linearized and fuzzy programming technique for multi-objective linear programming problems was not applied correctly for this problem.

“…Jolai et al [24] dealt with a multi-objective unequal sized DFLP with pickup/drop-off locations. Ardestani-Jaafari [25] discussed proper formulation of DFLP solutions in Abedzadeh et al [26] where dynamic flexible bay layout problem formulation with three objectives: minimizing material handling and relayout cost, maximizing adjacency ratio, and minimizing shape ratio difference was discussed. Chen [27] introduced a new data structure for solution representation in hybrid ant colony optimization for large problems.…”
