时态因果诊断模型TCDM及其应用(Ⅱ)——时态信息的描述与处理

Temporal Causal Diagnostic Model TCDM and Its Application(Ⅱ) ——Temporal Information Describing and Processing

根据Ａｌｅｎ的时间世界理论，提出了具有因果关系的事件间的时态关系类型、时延区间、时态范围及可接受性等概念，导出了可接受时态范围之间的各种约束及相互关系。结合ＴＣＤＭ因果诊断模型，分别就时态信息描述、时态信息传播的一般过程、时态一致性检验、时态信息传播的算子等进行了研讨，并给出相应的方法及性质。

Based on Allen′s theory of the time world, concept of temporal relationship type between objects with causal relationship, time delay interal, temporal extent and acceptable temporal extent are presented. Constraints and relationship between acceptable temporal extent are introduced. By their combination with TCDM(Temporal Causal Diagnostic Model), temporal information describing, general process of temporal information propagating, tempotal consistency cheeking and operator of temporal information propagating are discussed. In the meanwhile, some algorithm and character about temporal information processing are given.
