The purpose of this paper is to propose a new group decision‐making approach, which can only use simple mathematical calculations to perform a group decision‐making task.
The large column and large row (LCLR) method is designed and applied.
The paper finds four propositions to support LCLR methods to be a simple and effectual means for group decision making.
The aggregated matrix constructed in LCLR methods should be generated from non‐contradictory circles.
Effective group decision‐making results can be obtained by easily used methods, not necessarily by using complex mathematics technology to conduct the task.
The new approach based on LCLR methods proposed in this paper may be one of the most easily used and effective means for group decision making.
