DS证据合成规则评价方法研究

DS证据理论由于其应用广泛,成为研究的热点之一。由于其应用不同,DS证据理论遇到了一些问题,尤其是冲突证据合成问题,为此,不少学者都提出自己的解决办法。然而,针对合成方法的评价方法却很少有报道,算法优越性几乎都是通过主观逻辑判断的方法,通过实例对比,来说明算法的好坏。通过对合成方法的研究,提出了主客观结合的合成规则评价方法。评价方法以主观评价为基础,建立了客观评价体系及数学模型,客观评价体系有多个评价规则组成,综合说明合成方法的优劣,从而建立了合成方法的评价理论。最后,通过实例验证了评价方法的正确性。

Evaluation rule for DS evidence combination

Because of widely use of DS evidence theory,it became the research focus.The DS evidence theory met with some problems,particularly in the conflict evidence combination,therefore,the synthesis of the scholars had put forward their solutions.However,the synthesis of the assessment methods were very few reports,almost all the algorithms’ superiority are based on the subjective judgement,which was to illustrate good or bad by examples comaprision with each other.New subjective and objective evaluation rules were proposed.Based on subjective evaluation,objective evaluation system was established and the mathematical model,objective evaluation system of rules had more than one assessment,which jointed to indicate the merits of synthesis,thus establishing a synthesis evaluation theory.Finally,the examples are to validate the correctness of evaluation rules.
