【摘要】 由于各自独立证据源采集信息的种类、时刻和周期都不同,组合时多元证据间时差呈随机性,若直接使用D-S组合规则,可能产生与知觉相悖的结果。文中使用时效函数衡量证据有效性与时间关系,并将其引进信任函数,用于地震信息判定级融合评估,仿真实验取得有意义结果。更多还原

【Abstract】 Multiple independent sources always collect information at different time. So the traditional Dempster-Shafer theory is unadapted for the combination of multiple evidences from different time and their intervals are random. Time-effect function is defined to describe the changing credibility over time and joints in the belief function. Then it is applied to the marine earthquake information fusion at the determinant level. The simulation results are significant compared with the traditional D-S theory.更多还原
