A novel general framework for automatic and cost-effective handling of recoverable temporal violations in scientific workflow sy
Due to the complex nature of scientific workflow environments, temporal violations often take place and may severely reduce the timeliness of the execution’s results. To handle ...

Localized Temporal Reasoning: A State-Based Approach
We are concerned with temporalreasoning problems where there is uncertainty about the order in which events occur. The task of temporal reasoning is to derive an event sequence co...

Modelling CSP Solution Algorithms with Petri Decision Nets
The constraint paradigm provides powerful concepts to represent and solve different kinds of planning problems, e. g. factory scheduling. Factory scheduling is a demanding optimiz...
