摘要: 在Dezert-Smarandache理论(DSmT)中组合规则众多,其性能直接影响DSmT的最终融合结果。为此,对组合规则的性质进行研究,提出一种DSmT组合规则性质分析方法,从合成性质、时序性质和工程可用性质3个方面对DSmT的组合规则性质进行描述。实验结果证明,该方法提出的3类性质能较全面地反映组合规则的特性。

Abstract: Dezert-Smarandache Theory(DSmT) is an effective information fusion method for highly conflicting evidence problem of Dempster-Shafer Theory(DST). Combination rules play an important role in DSmT fusion. The fused result depends on the performance of combination rules. Different combination rules are suitable for dissimilarity evidence in distinct condition. The properties of combination rules are analyzed in three aspects as combination property, time series property and engineering property. Simulation results show that the properties presented characterize the combination rules roundly. It offers a theoretic foundation for analysis, improvement and application of DSmT combination rules.

Key words: Dezert-Smarandanche Theory(DSmT), Dempster-Shafer Theory(DST), uncertain reasoning, information fusion, performance analysis, combination rule
