摘要
无法准确度量证据间的冲突程度是D-S证据理论存在的一个基本问题。为了有效地解决此问题,基于Bray-Curtis相异度公式,提出了一种新的冲突度量方法,它满足非负性、规范性、对称性、一致性和三角不等式等冲突度量性质,具有计算负担小、度量精度高的优点。通过理论证明以及实例仿真验证了所提方法的有效性。
A basic problem of D-S evidence theory is that it cannot accurately measure the degree of conflict between the pieces of evidence.In order to effectively solve this problem,a new conflict measurement method based on Bray-Curtis dissimilarity formula is proposed.The proposed conflict measurement method meets the conflict measurement properties of nonnegativity,normalization,symmetry,consistency and triangular inequality,and has the advantages of low computational burden and high measurement accuracy.The effectiveness of the proposed method is verified by theoretical proof and example simulations.
