A two-phase fuzzy approach for solving multi-level decision-making problems
A two-phase fuzzy goal programming (FGP) approach is developed for MLLP problems. The first phase finds the solutions to satisfy decision makers in MLLP problems. An adjustment scheme is then proposed to adjust the relative satisfaction. Each DM can have the satisfaction degree that meets the requirement for MLLP problems.
