At present, workflow management systems have not sufficiently dealt with the issues of time, involving time modelling at build-time and time management at run-time. They are lack of the ability to support the checking of temporal constraints at run-time. Although some approaches have been devised to tackle this problem, they are limited to a single workflow and use only static techniques to ver...

Today’s workflow management systems have not sufficiently dealt with time information, which involves time modeling at build-time and time management at run-time. As a consequence, workflow management systems are short of the ability to support the checking of temporal constraints at run-time. Although several approaches have been devised to tackle this problem, they are limited to a single wor...

With the emergence of service-oriented architectures (SOAs), workflow management systems are being used to create applications from service compositions. Because service compositions may extend across platforms, domains, and virtual organisations, classical implementations of workflow management systems must be extended to address interoperability and reliability. In particular, there is a need...

Most existing workflow management systems (WFMSs) are based on a client/server architecture. This architecture simplifies the overall design but it does not match the distributed nature of workflow applicationsand imposes severe limitations in terms of scalability and reliability. Moreover, workflow engines are not very sophisticated in terms of data management, forgetting the fact that workflo...

Workflow management systems have been widely used in many business process management (BPM) applications. There are also a lot of companies offering commercial software solutions for BPM. However, most of them adopt a simple client/server architecture with one single centralized workflow-management server only. As the number of incoming workflow requests increases, the single workflow-managemen...

Document Management is an important component of a workflow management system. XML has become a prominent language for document processing and management, and has an additional advantage of managing persistent documents using XML document management system. In this paper, we develop an XML Document Centric Workflow Management System (XDoC-WFMS) for specifying, executing and controlling workflow...

This book offers a comprehensive introduction to workflow management, the management of business processes with information technology. By defining, analyzing, and redesigning an organization’s resources and operations, workflow management systems ensure that the right information reaches the right person or computer application at the right time. The book provides a basic overview of workflow ...

In this report, we examine the workflow management process from a scheduling perspective. Recognizing that effective workflow management requires an ability to efficiently allocate limited resources to tasks over time, we concentrate on characterizing this domain as a continuous distributed scheduling problem and on understanding the requirements and opportunities for providing workflow schedul...

Web-based interorganizational workflows need efficient time management. Variations of activity durations and branching distributions on or-split nodes make it necessary that we treat time management in workflows in a probabilistic way. We introduce the notion of duration histograms for capturing the available temporal information about workflow execution, define the necessary operations for com...

Time management is a critical component of workflow-based process management. Important aspects of time management include planning of workflow process execution in time, estimating workflow execution duration, avoiding deadline violations, and satisfying all external time constraints such as fixed-date constraints and upper and lower bounds for time intervals between activities. In this paper,...
