IT enabled organizations strive for overall improvement in performance with the use of tools capable of forecasting the stability and growth as well as failure. This paper contributes by introducing a technique and a model in Business process reengineering with Theory of constraints using dynamic workflow system enhanced with artificial intelligent ‘agents’ to observe the impact of flexibility ...

Today’s information systems do not support adaptive workflow: either the information system abstracts from the workflow processes at hand and focuses on the management of data and the execution of individual tasks via applications or the workflow is supported by the information system but it is hard to handle changes. This paper addresses this problem by classifying the types of changes. Based ...

One of the main tasks of workflow management systems is the coordination of activities in business processes. This paper introduces a solution framework to support adaptive workflows with complex and unstructured task dependencies. In the first section, the research direction is outlined and a short overview of the PoliFlow project is given. Then, requirements for enterprise process management ...

Existing workflow middleware executes tasks orchestrated by rules defined in a carefully handcrafted static graph. Workflow management systems have proved effective for service-oriented business automation in stable, wired infrastructures. We introduce a radically new paradigm for workflow construction and execution called open workflow to support goal-directed coordination among physically mob...

In the Grid computing community, there are several approaches to execute not only single tasks on single Grid resources but also to support workflow schemes that enable the composition and execution of complex Grid applications. The most commonly used workflow model for this purpose is the Directed Acyclic Graph (DAG). Within the establishment of the Fraunhofer Resource Grid, we developed a Gri...

Workflow management systems require advanced transaction support to cope with their inherently long-running processes. The recent trend to distribute workflow executions requires an even more advanced transaction support system that is able to handle distribution. This report presents a model as well as an architecture to provide distributed advanced transaction support. Characteristic of the t...

Workflow Management Systems (WFMSs) are becoming very popular and are being used to support many of the day to day workflows in large organizations. One of the major problems with workflow management systems is that they often use heterogeneous and distributed hardware and software systems to execute a given workflow. This gives rise to decentralized security policies and mechanisms that need t...

Dynamic evolution and adaptation of workflow models due to process (re)engineering activities and dynamic changing situations of the real process is one of the most important challenges in workflow management. In this paper, we present an approach for the management of evolving workflow specifications which copes with the evolution of a workflow schema and the dynamic modification of workflow i...

As many of the large-scale scientific applications executed on Grids are expressed as complex scientific workflows, workflow management has emerged as one of the most important Grid services in past few years. Scientific workflows can be defined as the aggregation of Grid application services, which are executed on distributed Grid resources in a well defined order to satisfy the specific requi...

BACKGROUND Older adults with chronic disease struggle to manage complex medication regimens. Health information technology has the potential to improve medication management, but only if it is based on a thorough understanding of the complexity of medication management workflow as it occurs in natural settings. Prior research reveals that patient work related to medication management is complex...
