Specifying historical Consequence and Postponed Effect Properties in Real-Time Systems
Résumé
In this paper, we introduce a new formalism based on interval temporal logic for reasoning about actions which take into consideration duration constraints. It includes two new concepts: postponed effect and historical consequence. The first one allows to specify a behavior in which a reaction not only depends on the time at which an action occurs but also on duration properties that means holding on states contained in certain time interval. In this case, the execution of the reaction will be postponed until a duration is satisfied. The second specify properties that depend on the current state of the system and also on past states and previously executed actions. It defines the relationship between system behavior in the future and its history.
