摘要：
Utilizing the data envelopment analysis (DEA) model for aggregating preferential rankings helps improve efficiency of the voting system. Recent elections often have a large number of abstentions and invalid ballots, making it necessary to incorporate abstentions into voting models. Firstly, this paper introduces a preferential voting DEA model with abstentions, in which the raw votes are expressed as interval values and the width of the interval characterizes the number of uncertain votes, the objective function is to maximize the candidate's weighted voting score, and the constraints put restrictions on the place weights to ensure a proper importance order of different places. Secondly, to account for the role of opinion leaders in influencing voters by different means (social-media, advertising,...) in real-world elections, we explicitly incorporate these opinion leaders/brokers as a moderator into a preferential voting model with abstentions and introduce the moderator-involved-consensus preferential voting (MICPV) model. The aim of the model is to achieve a maximum agreement/consensus level between the moderator's expectation and the voters' collective choice. The optimal allocation of all uncertain votes allows the moderator to maximize his/her influence over the voters to achieve the minimum deviation between his/her expectation and the aggregate scores of the candidates. Economic significance of the proposed models is also discussed. Numerical examples are presented to illustrate how the proposed models work for different voting scenarios.
