| 摘 要: 通过分析态势评估的过程,指出态势评估的本质是根据已发生事件,预测未来发生事件的趋势。本文分析 了态势评估中已有黑板模型的不足,以及黑板模型的优缺点,提出基于事件驱动与分级多层黑板模型的态势评估方法, 克服了因黑板边界划分带来的黑板推理的不准确性,使得态势评估更加准确与直观。 |

                | Abstract: By analyzing the process of Situation Assessment(SA),we regard that SA is a process of forecasting happening events by comprehending happened events.Based on studying the blackboard model and the shortages of old Blackboard model,we foreword a new method of multilayer blackboard based on event-driving which gets rid of the shortage of inaccurate information because of uncertain boundary of blackboard,and make the SA being more accurate and intuitionistic. |
