The Gaia methodology (Wooldridge et al., 2000) has been the rst complete methodology for the analysis and design of multiagent systems. However, the original version of Gaia su ered from the limitations of being suitable for the analysis and design of closed multiagent systems and of adopting non-standard notation techniques. For these reasons, several extensions to the basic Gaia methodology h...

The paper presents the initial model proposed for the Gaia Digital project. This three-year project is currently starting off within the Portugal Digital Initiative, within the Information Society operation program framework. It provides a digital city counterpart for Vila Nova de Gaia, with around 288000 inhabitants, considering 2001 figures. The Gaia Digital model is briefly described and its...

There is a need for agent oriented software engineering (AOSE) methodologies that support the conceptual modelling of mobile agent systems. In this paper, we present m-GAIA, our extension to the GAIA methodology for modelling mobile agent systems. m-GAIA incorporates explicit constructs to perform the analysis and design of multiagent systems which include mobile agents. We also present our exp...

This paper presents a multicriteria decision model for selecting a portfolio of information system (IS) projects, which integrates strategic and organizational view within a multicriteria decision structure. The PROMETHEE V method, based on outranking relations is applied, considering the c-optimal concept in order to overcome some scaling problems found in the classical PROMETHEE V approach. T...

This paper describes how to refine a Gaia design by applying agentoriented extensions of UML. First, we show how the Gaia Interaction model can be improved by applying the first two layers of the Agent Interaction Protocol (AIP) of AUML. Second, Gaia Agent and Service models are refined by applying the AIP’s third layer combined with Extended UML Class Diagrams. Third, Gaia Organisational Struc...

Assembling and simultaneously using di↵erent types of distributed computing infrastructures (DCI) like Grids and Clouds is an increasingly common situation. Because infrastructures are characterized by di↵erent attributes such as price, performance, trust, greenness, the task scheduling problem becomes more complex and challenging. In this paper we present the design for a fault-tolerant and tr...
