A Large-Scale Group Decision-Making Consensus Model considering the Experts’ Adjustment Willingness Based on the Interactive Weights’ Determination

Table 24

The group consensus levels and the adjustment costs of the different a.

Iteration (t)	a = 0.6		a = 0.7		a = 0.8		a = 0.9		a = 1.0
	(1)	(2)	(1)	(2)	(1)	(2)	(1)	(2)	(1)	(2)
0	0.7644	0	0.7973	0	0.8302	0	0.8631	0	0.8960	0
1	0.7689	1.4830	0.8026	1.4830	0.8362	1.4830	0.8699	1.4830	0.9035	1.4830
2	0.7725^T	2.8327	0.8067	2.8327	0.8410	2.8327	0.8752	2.8327	0.9094^T
3	0.7860	4.4169	0.8099^T	4.4169	0.8446^T	4.4169	0.8793	4.4169
4			0.8137	5.1305	0.8489	5.1305	0.8841^T

Note. (1) and (2) represent the group consensus level and the adjustment cost, respectively. 0.7725^T represents that the consensus level is 0.7725 at the second round of the iteration process and this stage is the last stage.
