TOWARDS A TEMPORAL COHERENCE MANAGEMENT IN REAL-TIME KNOWLEDGE-BASED SYSTEMS

The multi-agent system paradigm emerges as an interesting approach in the Knowledge-Based System (KBS) field when distributed problem-solvin g techniques are required. On the other hand, temporal representation and reasoning problems arise in a wide range of KBS application areas where time plays a crucial role. In this paper, we show that when agen ts run concurrently and access common temporal data, some problems of coherence arise. We analyse the different cases in which an incoherenc e in temporal information can occur and provide a method to tackle thi s problem. In this method, conflict management is handled by means of exception handlers and control rules allowing the users to explicitly define their own strategy for temporal coherence solving.
