态势估计中一种基于概率时间网络的时间推理方法

A Temporal Reasoning Method Based on Probabilistic Temporal Network in Situation Assessment

分析了时间推理在态势估计系统中的重要作用,介绍了时间区间理论。通过对态势估计系统中事件的分析,对相互排他过程和完备相互排他过程进行了建模。利用概率时间网络,对完备相互排他过程进行时间推理,并以一个具体的实例,对此过程进行了说明。

This paper analyzes the important effect of temporal reasoning in the situation assessment system, introduces the temporal interval theory. By analyzing the events in the situation assessment system, the exclusive process and the exhaustive and exclusive process are modeled. This paper fulfills temporal reasoning for the exhaustive and exclusive process by using the probabilistic temporal network, and shows the process by a real-world example.
