Decision Support System Based on Grid Workflow

Abstract: Grid technology brings about a lot of innovative ideas and technologies for the development of Decision Support System. The existence of description languages, semantics, service publishing methods and Grid middleware have up to now enabled interoperability between decision resources available across the Grid environment. However, there is an emerging need for the ability to dynamically discover how available services, resources and data could be utilized not only to process a task, but to achieve the desired outcome in the most suitable manner. In this paper, we investigates the emerging need for Grid workflow to aid decision support on the Grid and proposes a Grid workflow scheduling system that is a Petri net-based graph model and incorporates a reasoning system designed to perform such a task
