A support framework to address the repair-based reactive scheduling problem is proposed. It is based on an explicit domain knowledge representation and a constraint programming approach. When an unforeseen event occurs, the framework captures the in-progress agenda status, as well as the event effect on it. Provided that good quality solutions can be reached in low CPU times, alternative solution scenarios focusing on stability and regular performance measures can be posed for each problem.
