中文摘要：

为有效处理冲突相关的不确定性时间知识,在已有研究基础上，基于扩展模糊时间Petri网，引入变迁的模糊触发区间擞表隶使能变迁触发的不确定性,结合模糊时间函数和可能性值的运算来描述和分析各冲突事件发生的不确定性。能够针对冲突事件的各种时间苯确定性问题进行定量分析，可以解决复杂情况下的时间知识推理和验证。其相对于已有方法具有冲突分析精确、计算简单、适用面广的特点。

英文摘要：

In order to process the uncertain temporal knowledge about conflict, the paper introduces the fuzzy trigger interval based on the extended fuzzy timing Petri net to represent the uncertainty of enabling transition on the basis of existed research. Combined with fuzzy time functions and computation of possibilities, the model can represent and analyze the occurring uncertainty of each event involved in conflict, thus analyze quantitatively various temporal uncertainty issues of events involved in conflict and solve complicated problems of temporal knowledge reasoning and validation. Compared with existing ones, it has some promising properties, such as accurate analysis of conflict, simple computation, and suitable to more situations.
