基于群决策考虑属性效用一致性的DEA他评交叉效率公共权重排序法

针对数据包络分析(DEA)交叉效率方法大多是面向结果采用平均方式集结交叉效率,没有考虑评价过程中属性效用数据及其变动的特性,导致大量决策信息丢失、相对效率评价值与被评价决策单元的指标值关联性不够等问题,以交叉效率评价过程为导向,引入群决策理论,研究属性偏好及其属性效用变化特征,运用熵权法分析属性效用稳定性,发现评价中存...

A common-weight ranking method for DEA peer-efficiency based on group decision-making and considering the consistency of attribute utility

For a class of leader-following heterogeneous linear networked multi-agent systems, random network-induced delays and packet dropouts in the feedback and forward channels of each agent are considered, and an observer-based networked multi-agent cooperative output tracking control scheme is proposed. In this scheme, the leader agent produces a control prediction sequence and an output prediction sequence based on its delayed output and the system reference signal at each time instant. The former is used to actively compensate for random network-induced delays and packet dropouts in the control loop of the leader agent, and the latter is sent to following agents. Each following agent generates a control prediction sequence at each time instant based on its delayed output and the output prediction sequence received, which is employed to actively compensate for random network-induced delays and packet dropouts in the control loop of the following agent. Then the stability of the closed-loop networked multi-agent control system is analyzed. Finally, the effectiveness and feasibility of the proposed scheme are verified by practical experiments.
