针对现有时序逻辑对复杂不确定时间信息描述和推理方面的局限性,定义了直觉模糊不确定时间区间与时间间隔,构造了未知时刻的直觉模糊时序逻辑(IFTL)预测模型,提出了基于IFTL的不确定时间推理方法,较好地解决了时间推理精度不高的问题.同时,定义了直觉模糊集间的重叠度,并提出了基于此的知识模型及时间网络的一致性检验方法.最后通过典型实例验证了所提出的时间推理方法的有效性和优越性.
Aiming at the limitations of current temporal logic in describing and reasoning uncertain and uncertain time information, the intuitionistic fuzzy time interval and time interval are defined, and the intuitionistic fuzzy temporal logic (IFTL) prediction model is constructed. Based on IFTL , This paper solves the problem that the precision of time reasoning is not high.At the same time, the degree of overlap between intuitionistic fuzzy sets is defined and the consistency test method based on this knowledge model and time network is proposed. The validity and superiority of the proposed time inference method are verified through a typical example.
