  • The maximum expert consensus model (MECM) is an important decision method in group decision making (GDM). In previous research, decision makers' (DMs) soft consensus thresholds are often predetermined and fixed in MECM, leading to decreased effectiveness in achieving consensus. Therefore, we propose flexible MECMs with dynamic feedback adjustment mechanisms (DFA-MECMs) to guides DMs to modify consensus thresholds in CRP. However, dynamic adjustments of consensus thresholds in a real-world decision environment may lead to uncertainties in unit opinion adjustment costs. Moreover, DMs have different risk preferences on this uncertainty. To solve this problem, we employ robust optimization methods to construct three robust DFA-MECMs with different degrees of conservatism. Additionally, we develop a reference budget model to obtain a feasible budget range of robust DFA-MECMs. Furthermore, the effectiveness and superiority of robust DFA-MECMs are demonstrated using the consensus-achieving example of the carbon emission standard. Finally, sensitivity analysis and comparison analysis are presented and discussed.

    Table 2.  Consensus reaching process.

    Input: $ c_i, o_i, \gamma, B, M $
    Output: $ \bar{o}, \bar{o}_i, x_i, \varepsilon_i, w_i, TL_i, CL_i $
    Step 1: Solve the RB-DFA-MECM and determine whether the budget provided by the moderator is within the range of the baseline budget: (1) if $ B $ is within the range, go to step 2; (2) Otherwise, robust DFA-MECMs has no solution, which means there is no expert reach consensus, then, go to step 6.
    Step 2: Substitute basic information into robust DFA-MECM for calculation.
    Step 3: Solve the robust DFA-MECM and determine if the model has a solution at this point. If there is no solution, adjust the value of $ \gamma $ and return to Step 2, otherwise, go to Step 4.
    Step 4: Calculate the value of $ CL_i $ and $ TL_i $ based on the data obtained from Step 2.
    Step 5: Judge whether the DMs are satisfied with the solution. If DMs are not satisfied, they can further adjust their $ \varepsilon_i $ or $ \gamma $ and return to Step 2. If DMs are satisfied, then output the final solution.
    Step 6: End the dynamic feedback adjustment CRP.
