Abstract: Highlights•A three-way multi-scale decision-making model in incomplete environments is built.•A fusion method under multi-scale information systems based on the BWM is studied.•A TOPSIS method based on gray relational analysis and BWM is explored.•An evidential TWD method based on the information divergence is constructed.
