With increasingly widespread adoption of workflow technology as a standard solution to business process management, much effort is put on designing appropriate workflow models. The reuse of existing models has been recently suggested to support more efficient workflow design, which requires the storage, search and composition of workflow models. In this paper, we propose a new framework of work...

XML Process Definition Language (XPDL) is the language proposed by the Workflow Management Coalition (WfMC) to interchange process definitions between different workflow products. The goal of XPDL is to provide a Lingua Franca for the workflow domain allowing for the import and export process definitions between a variety of tools ranging from workflow management systems to modeling and simulat...

In this paper, we propose a new failure-recovery model for workflow management systems (WfMSs). This model is supported with a new language, called the workflow failure-handling (WfFH) language, which allows the workflow designer to write programs so that s/he can use data-flow analysis technology to guide the failure recovery in workflow execution. With the WfFH language, the computation of th...

Despite the great effort devoted to the development of Workflow models and Workflow Management Systems during the last decade, a strong foundation about workflow development is still to come. Assuming that a workflow is a complex software product, in this paper we argue that the principles and techniques of software development — in particular, methodological concerns— can help in the developme...

A Grid Workflow is critical to grid computing for its ability of creating complex grid computation by connecting different grid jobs logically. User can easily define and reuse the workflow for their applications that are loosely coupled. In this paper, we proposed a Grid Workflow Management System (GWMS) to provide the interface of processing workflow with grid schedulers, e.g., Sun Grid Engin...

Workflow management is an important part of scientific experiments. A common pattern that scientists are using is based on repetitive job execution on a variety of different systems, and managing such job execution is necessary for large-scale scientific workflows. The workflow system should also be client-based and able to handle multiple security contexts to allow researchers to take advantag...

Complex, end-to-end business processes, such as building a Boeing 747, are certainly not the first process a workflow-management infrastructure implements within an enterprise. As an example of an ultimate workflow-implementation goal, however, the process for building a Boeing 747 serves as an excellent source of requirements. WFMS architects can subsequently debate whether a requirement’s sol...

The exact and timely analysis of automated business processes through the analysis of protocol data is one factor for the use of workflow management systems in organizations. While in the past the automated routing and distribution of work have been prevailing factors in the marketing of workflow applications, the side-effect of having actual and precise business data for analysis yields many o...

Workflow technology is established in the business domain for several years. This fact suggests the need for detailed investigations in the qualification of conven-tional workflow technology for the evolving application domain of e-Science. This chapter discusses the requirements on scientific workflows, the state of the art of scientific workflow management systems as well as the ability of co...

Workflow management is emerging as a challenging area for databases, stressing database technology beyond its current capabilities. Workflow management systems need to be more integrated with data management technology, in particular as it concerns the access to external databases and as a support technology for workflow management, to support intelligent exception handling and transaction mana...
