As indicated in the literature, agent-based technology should naturally fit the architecture of a travel support system. However, proposals presented thus far have been relatively limited in scope or have not gone beyond early planning stages. The aim of this note is to introduce a comprehensive framework for delivering personalized travel services using an agent infrastructure.

Autonomous agents are not so difficult to construct. Constructing autonomous agents that will work as required is much harder. A clear way in which we can design and analyze autonomous systems so that we can be more confident that their behaviour is as required is to use formal methods. These can, in principle, allow us to exactly specify the behaviour of the agent, and verify that any implemen...

In this paper, we demonstrate the use of agents in implementing a collaborative work process. We use the FIPA ACL to implement communication between agents to provide a convenient means for human to delegate mundane tasks to software agents. An interface for each agent implements the communication between human actors and agents. Such interface and the subsequent communication performed by agen...

Cognitive agent programming frameworks facilitate the development of intelligent virtual agents. By adding a computational model of emotion to such a framework, one can program agents capable of using and reasoning over emotions. Computational models of emotion are generally based on cognitive appraisal theory; however, these theories introduce a large set of appraisal processes, which are not ...

The actual economic paradigm is based on a strongly cooperative model that tries to support a more competitive and global organizations response. With cooperation comes an intrinsic need interconnection and interoperability of information systems among business partners. This represents, in many areas, a huge organizational challenge, being the field of information, and communication security o...

Software Agents interaction involves uncertainty. In order to model and formalize agents’ interaction, three properties: public, private and protected are adopted to precisely represent the belief-desire-intension (BDI) agent, and agent’s relationships have been interpreted in terms of cooperation, coordination and competition based on BDI agent model. An agent’s uncertainty management framewor...

In software engineering community there is an increasing effort of design and development of multi-agent systems (MAS). However, agent system development is currently dominated by informal guidelines, heuristics and inspirations rather than formal principles and well defined engineering techniques. In this paper we present a framework for agent-based software development called Agent-SE. We pre...

Current technologies for Home and Building Automation (HBA) require an explicit interaction with the user and allow a static set of operational scenarios, defined during system implementation. More flexible HBA solutions are needed to enable the so-called Ambient Intelligence, permitting an automatic coordination and control of appliances and subsystems located in a given environment. This pape...

Spatial information grid (SIG) is a spatial information infrastructure that has the capability of providing services on-demand. In this paper, agent technology is adopted to construct a SIG framework, which contains three layers: users/applications layer, agent services layer and information layer. Different applications can get their spatial information via agent services, and agent services m...

With the increasing importance of complex software systems in the software industry, the need for using agent technologies to develop large-scale commercial and industrial software systems is growing rapidly. Such systems are complex and there is a pressing need for system modeling techniques to support reliable, maintainable and extensible design. G-Nets are a type of Petri net defined to supp...
