| 摘要: |
| 在战场态势估计中, 常常需要判断事件发生的时间顺序, 而对事件发生时间的观测往往含有统计不确定性。这里将假设检验理论引入时间推理, 建立了一种判别两个事件发生顺序的新方法, 同时研究了在统计不确定性下时间顺序的传递性, 从而有效增强了态势估计中对时间关系的描述和推理能力。 |

| Abstract: |
| In tactical SA, it is important for commanders to decide the temporal order of events. But imprecise observations make it diffcult to make. In this paper, hypothesis detection theory is introduced into temporal reasoning, and a new method to decide the temporal order of two events under stochastic imprecision is developed. The transitivity of the stochastic order is also discussed, which enhances the ability of describing time relation and temporal reasoning in situation assessment. |
