Using qualitative reasoning with geographic information, contrarily, for instance, with robotics, looks not only fastidious (i.e.: encoding knowledge Propositional Logics PL), but appears to be computational complex, and not tractable at all, most of the time. However, knowledge fusion or revision, is a common operation performed when users merge several(More)
In recent years, Building information model (BIM) has been adopted by the construction industry as a new way to design a project through the digital model. BIM helps to simplify the communication and the cooperation between different actors during the project life-cycle, especially for big projects with complex geometry. Based on the concept of co-design,(More)
Geographic Information Systems (GIS) often use incomplete and uncertain information leading to inconsistency. Thus, a clear definition of information revision is required. In logic, most of the usual belief revision operations are characterized by a high computational complexity, which implies actual intractability even for rather small data sets. On the(More)
The revision problem is known to be a very hard problem. There is no revision algorithm which is able to handle a large amount of data. Geographical information systems (GIS) are characterized by a huge amount of data, often gathered from different sources of information, which are imperfect and whose quality can differ. Therefore GIS require the(More)
