基于PIC参数提出了TPIC参数，并提出用TPIC参数对证据理论融合系统性能进行评估的方法．融合的目的是为了得到对目标更准确、确定的认识，用TPIC参数给出了多证据融合系统融合输出对正确目标确定度的度量方法，通过度量融合后对正确目标的确定度来实现融合性能的定量评估，解决了以往熵方法评估仪以不确定性作为标准而不考虑融合结果正确性的问题，并由仿真实验验证了方法的有效性．

英文摘要：

The TPIC metric is proposed based on the PIC metric. And the evaluation for the fusion system with evidence theory is presented with the TPIC metric. The purpose of the fusion is to get more accurate knowledge about the target. Based on TPIC metric, a method for measuring the multi-evidence fusion system＇s certainty about the real target is proposed. The quantitatively evaluation is achieved by measuring the certainty. The problem occurred when evaluate in the conventional way which applies entropy theory with taking the changes of the information uncertainty as the criterion without taking into account the validity of the combination is solved by this method. The effectiveness of the proposed method is proved by simulation.
