ABSTRACT = {
In this work we consider a way to deal with the problem of unreliable 
observations when an agent is reasoning about dynamical systems as they are 
formalized and systematically studied in Sandewall's approach to reasoning about
action and change. The presence of incorrect observations can be detected in 
case it generates a contradiction. In this case a revision function resolves the
inconsistency by constructing alternative consistent descriptions of the system.
However, revision is in general expensive and therefore we define a delayed 
revision that postpones doing revision for some steps and we prove that it gives
results similar to immediate revision. We also examine some forms of 
preferential revision that reduce the number of alternative descriptions of the 
system. We finally consider the relations between our work and Gardenfors' 
approach to belief revision.
