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

Table 20

The change of GCL_t and adjustment cost.

Iteration (t)	The proposed model (M-1)		Without considering the interactive weights (M-2)		Without considering the experts’ adjustment willingness (M-3)
	Group consensus level	Adjustment cost	Group consensus level	Adjustment cost	Group consensus level	Adjustment cost
t = 0	0.8302	0	0.8976	0	0.8306	0
t = 1	0.8362	1.4830	0.9052	2.2941	0.8336	0.3218
t = 2	0.8410	2.8327	0.9108^T		0.8365^T	0.6979
t = 3	0.8446^T	4.4169			0.8389	0.7656
t = 4	0.8489	5.1305

Note. For example, 0.8446^T represents that the consensus level is 0.8446 at the third round of the iteration process and this stage is the last stage.
