标题： A case of combination of evidence in the Dempster-Shafer theory inconsistent with evaluation of probabilities

摘要： 证据累积的Dempster-Shafer理论是结合来自多个来源的数据的主要工具之一。 在本文中考虑了两个证据体在冲突系数非零情况下的组合的特殊情况。 结果表明，在这种情况下应用Dempster-Shafer组合规则会导致对组合证据的质量评估与通过应用全概率定律得到的相应概率的评估不同。 这一发现支持了在一般情况下对Dempster-Shafer分析结果进行概率解释是不合适的观点。 显示英文摘要

摘要： The Dempster-Shafer theory of evidence accumulation is one of the main tools for combining data obtained from multiple sources. In this paper a special case of combination of two bodies of evidence with non-zero conflict coefficient is considered. It is shown that application of the Dempster-Shafer rule of combination in this case leads to an evaluation of masses of the combined bodies that is different from the evaluation of the corresponding probabilities obtained by application of the law of total probability. This finding supports the view that probabilistic interpretation of results of the Dempster-Shafer analysis in the general case is not appropriate.
