自适应多层综合评判

Adaptive multi-layer comprehensive evaluation

  • 摘要: 针对因素集固定不变,使得多层综合评判(comprehensive evaluation,CE)模型难以应对因被评判对象不同而引起的变化问题,提出了自适应多层CE(adaptive multi-layer CE,AMLCE)模型,实现了动态CE;探讨了CE模型基于因素距离和相似度核的跨层权重转移机制,设计了相应的权重转移方案.为说明其合理性,通过熵正则设计并优化了另一种权重转移方案,证明了在统一设定下2种方案的等价性.通过经典型案例CE试验验证了所提AMLCE模型的有效性.

     

    Abstract: A fixed set of evaluation factors makes the multi-layer comprehensive evaluation (CE) model difficult to use when the set of evaluation factors changes with different objects to be evaluated. To solve this problem, in this paper an adaptive multi-layer comprehensive evaluation model is proposed to solve the limitation of constant set of evaluation factors. This new model enables dynamic comprehensive evaluation to facilitate comprehensive evaluation with changing evaluation factors. In the proposed model, the cross-layer weight transfer mechanism based on factor distance and similarity kernel is given, and the corresponding weight transfer scheme is designed. To illustrate the rationality, a weight transfer scheme is designed based on entropy regular optimization, and the equivalence of the two schemes under identical settings is proved. Comprehensive evaluation experiments on typical cases verify effectiveness of the proposed model for adaptive multi-layer comprehensive evaluation.
