Description:Agents and web services for grid computing

Abstract:Creating and using a design methodology for specific application contexts is a great challenge today. Till now each design methodology has been created for solving specific problems in well defined context and it does not exist a standard, general enough, methodology fitting all possible situations thus requiring (by organizations) great efforts in time and cost for creating, learning and /or using a specific design methodology. A solution to that can be given by the method engineering and multi agent system paradigm [2][3]. Method engineering provides methods and techniques for constructing ad-hoc design methodology ; in the proposed work it is used as a base for tuning techniques for creating multi agent system design methodologies (see Figure 1). In short some of the main elements are: the method fragment (the portion of existing methodologies to be reused), the method base (the repository where fragments are stored) and the MAS Metamodel (the Multi Agent System Metamodel that structures the system to be). The process to be followed is very huge and two tools have been created in order to support it; the first is a CAPE (Computer Aided Process Engineering) tool for aiding in the management of the new methodology creation and the second is a CAME (Computer Aided Method Engineering) for assisting the method designer in querying and interfacing the fragments repository. This CAPE tool was endowed with an extremely important capability: auto-instantiating in the right CASE tool for supporting each new created methodology. The CAPE tool was conceived as a multi-agent system (Figure 2) where each agent of the society has specific capability, specific goals and offers different services in order to support the designer during his work; for instance there are agents devoted to communicate with the users and to suggest them the right (or the most useful) choice through the collaboration with an expert system, some others are responsible of assisting the whole
