| 摘 要： | 提出了一种新的基于概率模型的排序优化方法．利用贝叶斯规则，结合各组成系统平均执行性能的信息，推导出一种新的相关度计算公式，较好地解决了结果融合中相关度规范化和均衡化的问题．经实验验证，该方法对结果进行了最优化排序，其实际执行性能超出了现有的任何一个组成系统的性能．

| Abstract: | The paper put forward a new optimal scheme based on a probability model. By using the Bayes rule and combining the information of the average performance of the component systems, a new relation degree formula was deduced and the problems on relational degree standardization and equilibrium were solved. The experiment results showed the new system provided the optimal ranking. |
