The Developments and Problems in Evidence Reasoning

综合论述了证据推理的进展和存在的问题，把证据推理与贝叶斯推理、模糊逻辑推理、基于规则的推理。随机集理论进行了横向比较，讨论了其间的必然的联系和为证据推理的发展提供的基础，随后总结了证据推理的改进及其在概率范围和模糊集等方面推广的进展，最后提出了证据推理的广泛应用及其研究方向．

The developments and problems of evidence reasoning are discussed in this article. Evidence reasoning is com-pared with Bayesian reasoning,fuzzy logic,rule-based reasoning and random set theory. Improvement of evidence reasoning andits extension to probability and fuzzy set are introduced It is found that evidence theory has many applications Finally, its direc-tion of further development is proposed.
