This thesis presents sets of technologies for enacting multi-agent based decentralised workflow systems. Its purpose is to tackle some of the existing problems in the con-ventional workflow research from the system architectural and engineering point of view. Some of the problems addressed

complex workflows. Therefore, many efforts have been made towards the development of workflow management systems for Grid computing. In this paper, we propose a taxonomy that characterizes and classifies various approaches for building and executing workflows on Grids. We also survey several

on scientific workflow approaches. The main aspect of our taxonomy categorizes provenance systems based on why they record provenance, what they describe, how they represent and store provenance, and ways to disseminate it. The survey culminates with an identification of open research problems in the field. 1.

The Workflow Patterns Initiative was established with the aim of delineating the fundamental requirements that arise during business process modelling on a recurring basis and describe them in an imperative way. The first deliverable of this research project was a set of twenty patterns describing

of many research projects and prototype systems. This tutorial provides an overview of research issues in provenance for scientific workflows, with a focus on recent literature and technology in this area. It is aimed at a general database research audience and at people who work with scientific data

Workflow management is a technology that is considered strategically important by many businesses, and its market growth shows no signs of abating. It is, however, often viewed with skepticism by the research community, conjuring up visions of oppressed workers performing rigidly-defined tasks

Abstract. In the main, the attention of workflow researchers and workflow developers has focussed on the process perspective, i.e., control-flow. As a result, issues associated with the resource perspective, i.e., the people and machines actually doing the work, have been largely neglected

in terms of interoperating with other workflow systems. In this paper, we discuss the limitations of contemporary workflow management systems, and then elaborate on various directions for research and potential future extensions to the design and modeling of workflow management systems. 1 Introduction

this paper we present the Exotica Research Project, currently in progress at the IBM Almaden Research Center. One of the goals of the project is to bring together industrial trends and research issues in the workflow area. It is for this reason that we have focused on a particular commercial
