D-S证据理论凭借其所制定的证据规则可以融合来自不同信息源的可能有效的证据信息,从而提高结论的真实度和可靠性。科学假说的确证通常是建立在不同证据支持的基础之上,因此,也需要一个能够融合所有证据的方法。本文将D-S证据理论应用于判断科学假说的可靠性。显然,这种方法可以很好地处理科学假说的多证据融合问题。D-S evidence theory,especially Dempster's rule is used to combine probabilistically independent sets of evidence to improve the reliability or dependability of evidence information associated with different data sources.Confirmation of scientific hypothesid is usually based on multiple sets of evidence.In this article,the D-S evidence theory is used to judge the reliability of scientific hypothesis.Obviously,the useful method proposed here can do good to the widely fields
