A Two-stage subgroup Decision-making method for processing Large-scale information

作者：

Highlights：

• A two-stage sub-group decision-making model is proposed for LSGDM problems.

• The equivalence test is used to eliminate the group-wise incompatibility.

• No assumptions are required to group DMs or alternatives in the proposed method.

• Different sampling methods and functions are considered to ensure the robustness.
