With the increasing demand for electric power, new theories have been studied by the scientific community. One of the most promising consists in splitting the electric grid in microgrids, each one composed by renewable and not renewable sources and various loads. These microgrids aim to be as much autonomous as it is possible in producing the energy they(More)
Nowadays several methodological approaches exist, each of them tightly tied up with the implementation platform supporting it. In this paper we propose an intermediate step toward the definition of a methodological approach for supporting the JACAMO framework. This paper resumes a previous work, focused on modeling BDI organizations, and we now address the(More)
Business process run-time evolution and adaptivity are two urgent objectives in the research agenda of dynamic workflow execution. Traditional languages as BPMN or BPEL take an imperative style for defining the exact sequences of activities to execute. The imperative approach identifies a narrow space of solution that is generally optimized by the(More)
Designing and developing BDI multi-agent systems would be facilitated by rising up the level of abstraction to use and by a methodological approach for managing it. To this aim it is common the integration of goal oriented analysis techniques with the design and implementation phases. In this fashion, our experience is that the use of an ontology in the(More)
In Philosophy, the term awareness is often associated to theories of consciousness and self-referential behavior. In computer science, the awareness is a topic of increasing relevance in both Software Engineering and Artificial Intelligence, being closely related to autonomy and proactiveness. We can distinguish two orders of awareness: the first order is(More)
The paper presents an agent-based simulation as a tool for decision making about automatic warehouses management. The proposed multi-agent system is going to be used in a real environment within a project developed with a company working on logistics. More in details, we have developed a simulation framework in order to study problems, constraints and(More)
Modeling and designing systems that require a high level of coordination, control and automation is a very difficult task. The problem is the lack of design processes able to cover all the features these systems present. This paper presents an extension of the ASPECS metamodel for supporting organizational and normative principles and it allows to define(More)
One of the current challenges of Service Oriented Engineering is to provide instruments for dealing with dynamic and unpredictable user requirements and environment. Traditional approaches based on workflow for orchestrating services provide little support for configuring at run-time the flow of activities. This paper presents a general approach for(More)
