The paper introduces the challenges in modern workflow management in distributed environments spanning multiple cluster, grid and cloud systems. Recent developments in cloud computing infrastructures are presented and are referring how clouds can be incorporated into distributed workflow management, aside from local and grid systems considered so far. Several challenges concerning workflow defi...

During the late 1990s it has become generally accepted in business that process (as opposed to functional) management is an essential element of world-class management. In an increasingly competitive environment, the role of the human manager has been challenged by sophisticated case handling and management systems, variously known as workflow automation, workflow systems and workflow managemen...

This special issue of Concurrency and Computation: Practice and Experience contains selected high-quality papers from the second International Workshop on Workflow Management and Applications in Grid Environments (WaGe2007), which was held on 17 August 2007 in Urumqi China [1]. The WaGe workshop series was aimed at providing an international forum for the presentation and discussion of research...

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...

Purpose – The paper aims to propose a web-based “intermediation hybrid architecture” for a workflow management system that integrates services by exploiting and combining the advantages of strict centralized topologies that use workflow engines, with totally distributed systems which use agent technologies. Design/methodology/approach – The proposed operational and technical architectures defin...

Workflow is an important approach for the specification and management of complex processing tasks. This approach is especially powerful for utilizing distributed service and processing resources in grid systems. Some researches on the combination of workflow and grid exist, leading to many approaches to grid workflow support. We describe our MOM-based Service Flow Management System composing c...

Workflow management systems help streamline business processes and increase productivity. This paper describes the design and implementation of the DartFlow workflow management system. DartFlow uses Web-browser embedded Java applets as its front end and transportable agents as the backbone. While Java applets provide a safe and platform independent GUI, the use of transportable agents makes Dar...

Background Integrating guideline knowledge with clinical workflow plays a critical role in effective guideline implementation strategies. Eight information management services promote integration of computerized systems into clinical workflow—recommendation, documentation, explanation, presentation, registration, communication, calculation and aggregation. The Guideline Elements Model (GEM) use...

This paper describes an operator workflow oriented information framework for services and network management. Particular attention is drawn on the requirement for a high-level management information specification. It proposes for this purpose a management information transformation formalism as a tool to specify the polymorph behavior of the information during its lifecycle across the operator ...
