abstract = {In this work, a multi-agent system (MAS) for supply chain dynamic configuration is proposed. The brain of each agent is composed of a Bayesian Decision Network (BDN); this choice allows the agent for taking the best decisions estimating benefits and potential risks of different strategies, analyzing and managing uncertain information about the collaborating companies. Each agent collects information about customer's orders and current market prices, and analyzes previous experiences of collaborations with trading partners. The agent therefore performs a probabilistic inferential reasoning to filter information modeled in its knowledge base in order to achieve the best performance in the supply chain organization.},

abstract = {In this paper, we discuss interaction interoperability in Collaborative Virtual Environments (CVE), intended to mean the ability of two or more users to cooperate despite the heterogeneity of their interfaces. To allow such interoperability, rather than focusing on the de-coupling of input devices from interaction techniques and from interaction tasks, we suggest integrating interactive systems at higher level through an interface standardization. To achieve this aim, we propose: i) an architectural model able to handle differences in input devices and interaction tasks; ii) an agent-based middleware that provides basic components to integrate heterogeneous user interfaces. We also present a prototype of an agent-based middleware able to support developers in the interconnection of monolithic applications and we introduce tools and languages we have used to formalize the interaction tasks considered in the case study.},

abstract = {In this paper, we present a service for a pervasive distribution of the computational load involved in the execution of high quality 3D rendering of medical volume data. The service is built upon an ad-hoc developed multi-agent middleware layer, which is in charge of executing user-defined tasks in hybrid peer-to-peer networks. Users' tasks are embedded in mobile agents and then spread in a platform composed by both fixed and mobile stations. Such agents are able to migrate among stations in order to ensure a certain degree of load balancing and dependability. The application scenario considered is a hospital, where intensive computing tasks can be edbend ectively executed on a large number of heterogeneous devices that are networked and typically only partially used. We also present the results of performance and dependability tests performed under real-world conditions.},

The proposed solution consists in a distributed agent-based software infrastructure that grants a high level of transparency from the user point of view. As a matter of fact, accordingly with the Utility Computing model, the user has just to submit its tasks and their input parameters; after that, the software infrastructure takes care of (1) encapsulating tasks in mobile agents; (2) distributing them in the virtual environment; (3) launching and controlling execution; (4) picking up results; and (5) handling computing stations. Finally, it is important to note that the infrastructure is able to integrate both fixed and mobile hardware resources to build a community of computing stations for task executions. As a consequence, such an infrastructure can get useful computing power even from stations (mobile devices) that have always been neglected by classic task execution platforms.},
