Workflow management is a core component of modern enterprise information technology infrastructure that automates the execution of critical business processes. Since enterprise transformation typically introduces changes to the corresponding business processes, it is important for modern workflow management systems to provide effective support for seamless incorporation of these changes. In thi...

Building a workflow management system (WFMS) is a large project. However, with the development of grid technology, it becomes easily to do that. In Open Grid Service Architecture (OGSA), everything is a service. Thus, a workflow management system can be easily built upon a set of services. Some workflow management services and important components are proposed in this paper. And the definition ...

A computational grid provides coordinated and transparent access to computing resources for grid users. Workflow management and resource discovery are two important functions of an intelligent grid. Workflow management refers to automatic workflow creation and coordinated workflow execution, and resource discovery facilitates resource allocation and claiming. In this paper we discuss workflow m...

This paper proposes a workflow management mechanism to address a neglected aspect of existing P2P computing platforms the lack of support for various computational models. In the workflow management mechanism, a workflow description file is used to define the workflow diagram of the target application. We develop a prototype system, and evaluate it using a test program to demonstrate how the wo...

workflow, resource management, resource model Resource management is a key issue in providing resource independence and efficient use of workflow resources. The paper has outlined a design of such a resource management system for enterprise workflow environments. It is capable of handling a large number of workflow resources that are independently managed by pre-existing resource systems. It in...

While the different aspects of flexible workflow management are still under discussion, the ability to adapt the structure of running workflow instances to modified workflow schemas is an important property of a flexible workflow management system. In this paper we present the formal foundation and conceptual design of dynamic adaptations in an object-oriented workflow management system. We des...

We survey formal frameworks for workflow modelling. We summarise important aspects of workflow management and approaches to evaluate current workflow management systems. We discuss a number of formalisms for workflow modelling, namely Petri nets, Temporal Logic, and Transaction Logic. We decribe how these formalisms are used specifically for workflow modelling, their possibilities and their dis...
