In this paper, a new approach for the mixed zero-one fuzzy goal
programs is presented. This approach
allows the decision-maker to set alternative fuzzy goal constraints to his/her
original ones. The alternative fuzzy goal constraints are considered, instead
of the original
ones, if certain situation
conditions are not satisfied. In addition to the linearization technique for the mixed zero- one
fuzzy goal programs, which has been given by Chang [C.T. Chang, Binary fuzzy goal programming, European Journal of
Operational Research, 180 (1), (2007),
29–37], another linearization technique for the binary goal programs is presented.
The suggested approach of using alternative fuzzy goal constraints by simultaneously utilizing the two linearization techniques is illustrated by a numerical example.
