Decision Support System Based on Grid Workflow
نویسنده
چکیده
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. Key-Words: Decision Support System; scheduling; Workflow; Grid

Grid Workflow for Decision Resource Scheduling
With the advent of Grid and application technologies, scientists and engineers are building more and more complex decision support applications to process large data sets, and scheduling distributed decision resources. Such decision resource scheduling processes require means for composing and executing complex workflows. Therefore, many efforts have been made towards the development of workflo...
متن کاملWorkflow Advisor on The Grid
There are an increasingly large number of web services available today. New services are constantly being introduced, each performing different tasks ranging from simple data transfer operations to highly complex engineering and mathematical processes. The existence of description languages, workflow tools, semantics, service publishing methods and Grid middleware have up to now enabled interop...
متن کاملArchitectural Plan for Constructing Fault Tolerable Workflow Engines Based on Grid Service
In this paper the design and implementation of fault tolerable architecture for scientific workflow engines is presented. The engines are assumed to be implemented as composite web services. Current architectures for workflow engines do not make any considerations for substituting faulty web services with correct ones at run time. The difficulty is to rollback the execution state of the workflo...

متن کاملSession C1 1. Employing WS-BPEL Design Patterns for Grid Service Orchestration using a Standard WS-BPEL Engine and a Grid Middleware
In BIS-Grid, a BMBF-funded project in the context of the German D-Grid initiative (http://www.d-grid.de), we focus on employing Grid technologies for information systems integration. The goal is to enable small and medium enterprises (SMEs) to integrate heterogeneous business information systems and to use external Grid resources and services with reasonable effort. To achieve this goal, we dev...
