When research in the area of office automation began more than 25 years ago [4] the typical enterprise infrastructure consisted of heterogeneous computing platforms and operating systems, different networking standards, a variety of email products and limited user interface technologies. These technical inconsistencies and the lack of processorientation within enterprises led to a slower-than-e...

Workflow management systems (WfMSs) have been used to support various types of business processes. As organizations adopt new working models, such as e-commerce, new challenges arise for workflow systems. One such challenge is that of quality of service (QoS) management. QoS management includes mechanisms that specify, compute, monitor, and control the quality of service of the products or serv...

We describe the CAWE framework for the management of contextaware workflow systems, based on Web Services. The framework is based on a hierarchical workflow representation supporting a synthetic and extensible specification of context-sensitive workflows, which can be executed by standard workflow engines. We have exploited the CAWE framework to develop a prototype application handling a medica...

Process, workflow, and groupware products both in the commercial and research worlds have each approached the problem of human communication and coordination with different sets of tools and technologies implemented from different perspectives. Each manages the dependencies between activities differently in addition to making different philosophical assumptions. While most of these tools repres...

Despite so many years’ development, the mainstream of workflow solutions from IT industries has not made ad-hoc workflow-support easy or inexpensive in MIS. Moreover, most of academic approaches tend to make their resulted BPM (Business Process Management) more complex and clumsy since they used to necessitate modeling workflow. To cope well with various ad-hoc or casual requirements on workflo...

This paper describes experiences from the implementation of backward recovery for a commercial production workflow system. As a result of our research we found that compensation based backwards recovery is the most suitable approach for an external solution. Most importantly, the work has demonstrated that providing business level backward recovery is possible in the workflow domain, and that e...

In the past few years there has been an increasing interest in distributed workflow management technology for the requirement of supporting business process in modern corporations. As the process in large enterprise tends to be across many branches which are distributed over a wide geographic area and have their own IT infrastructures, the current workflow management systems do not have suffici...

We present a generic and light-weight Grid workflow execution engine made available as a Grid service. A long-term goal is to facilitate the rapid development of application-oriented end-user workflow tools, while providing a high degree of Grid middleware-independence. The workflow engine is designed for workflow execution, independent of client tools for workflow definition. A flexible plugin...

Based on the analysis of limitation of existing workflow management system, a workflow management system based on micro kernel is researched and designed. In this system, a micro kernel based workflow engine is designed by separating the service implementation and activity scheduling; the workflow engine interface is defined to connect the related workflow components seamlessly; and then graphi...

This paper proposes a policy adjuster-driven Grid workflow management system for collaborative healthcare platform, which supports collaborative heart disease diagnosis applications. To select policies according to service level agreement of users and dynamic resource status, we devised a policy adjuster to handle workflow management polices and resource management policies using policy decisio...
