As part of the ongoing globalization process, software is no longer developed by a sole enterprise which is based at one single location only. In turn, distributed engineering teams are continuously modifying software by bringing in their local knowledge and country-specific expertise. Due to this cooperation on a global-scale, today's software engineers(More)
Preferences are useful when the space of feasible solutions of a given problem is dense but not all these solutions are equivalent w.r.t. some additional requirements. In this case, the goal is to find feasible solutions that most satisfy these additional requirements. In order to represent preferences, in this paper we use an extension of ordered(More)
—This paper describes a methodology based on Answer Set Programming (ASP) to work with incomplete geographic data. Source geographic data which describes a risk zone is translated to ASP description and it allows to solve query's which can not be solved by a normal GIS. An evacuation plan can change when new situations are presented, for instance traffic, a(More)
The paper proposes to use CR-prolog to add planning capabilities to a Geographical Information System. Cr-rules can restore the consistency of a program giving the diagnosis of possible causes of failure in a plan. In this paper we give an additional use for cr-rules: we propose to use cr-rules to obtain an alternative plan in case of the ideal plan fails.(More)
In this work, we present current results of our research which goal is to develop a decision support system using Answer Set Programming as an extension of a Geographic Information System to model vehicular evacuation plans. We also present why an Answer Set Programming approach seems to be appropriate to explore in order to create this extension. In order(More)
