Information security policies play an important role in achieving information security. Confidentiality, Integrity, and Availability are classic information security goals attained by enforcing appropriate security policies. Workflow Management Systems (WfMSs) also benefit from inclusion of these policies to maintain the security of business-critical data. However, in typical WfMSs these polici...

The goal of the BenchFlow project is to design the first benchmark for assessing and comparing the performance of BPMN 2.0 Workflow Management Systems (WfMSs). WfMSs have become the platform to build composite service-oriented applications, whose performance depends on two factors: the performance of the workflow system itself and the performance of the composed services (which could lie outsid...

In this paper, an approach to use task trees in a workflow management system (WfMS) is presented. As hierarchical models task trees capture several hierarchy levels of a workflow in one model. A workflow editor visualizes the models also as flowcharts similar to UML activity diagrams. The WfMS use these models as input and instantiates and executes them. The system is web-based and can be easil...

Cloud computing is a new benchmark towards enterprise application development that can effectively facilitate the execution of workflows in business process management system. The workflow technology can manage the business processes efficiently satisfying the requirements of modern enterprises. Moving workflows to a cloud computing environment enables the utilization of various cloud services ...

Solving workflow management system’s Distributed Computing Infrastructure (DCI) incompatibility and their workflow interoperability issues are very challenging and complex tasks. Workflow management systems (and therefore their workflows, workflow developers and also their end-users) are bounded tightly to some limited number of supported DCIs, and efforts required to allow additional DCI suppo...

Scientific workflows require the coordination of data processing activities, resulting in executions driven by data dependencies. Due to the scales involved and the repetition of analysis, typically workflows are analyzed in coordinated campaigns, each execution managed and controlled by the workflow management system. In this respect, a workflow management system is required to (1) provide fac...

Collaborative and dynamic workflow management systems in logistic companies require strong information systems and computer support. Business processes in such industries generally compose of several parts, a structured operational part and an unstructured operational part, or they could be composed of semistructured parts with some given and some unknown details. Unpredictable situations may o...

Today’s manufacturing industry requires product data management system (PDM) for efficient product development and production. Manufacturing industries must deal with competition, time to market, reduction of the cost of doing business, and rapid development of new services and products. To address these requirements industries must constantly reconsider and optimize the way they do business an...

Workflow management is crucial in monitoring and controlling business processes. Advancements have been made in computer-based workflow management, which allowed for the partial or complete automation of these processes. However, existing computer-based systems have not been successful in highly distributed domains. Hence, these domains have continued conducting their workflow management proces...
