Web Services technology is becoming the de-facto standard for integration of legacy applications within an organisation and for cross organisation enterprise application integration. Much work has gone into specifying Web Services functionality using workflow like techniques and production of software to enact such descriptions.

Web Services technology is becoming the de-facto standard for integration of legacy applications within an organisation and for cross organisation enterprise application integration (B2BEAI). Much work has gone into specifying Web Services functionality using workflow like techniques (BPEL4WS, WSCI, WSFL, XLANG) and production of software to enact such descriptions. However, most of this softwa...

In this paper, we discuss a new architecture for integrating and executing business process models with rules. It is based on a workflow engine that runs a BPMN-based business process model. On the lower level, rules are used to express the specific parts of the business logic. Rules working in the same context are grouped into a single task in the process model. Such a rule task is modeled by ...

Business visualization is an effective tool for business decision making and problem solving. Despite its obvious benefits, 3D visualization is far less common in practice than it should be due to the lack of software support. To address this problem, we have developed a workflow rendering engine that facilitates the 3D visualization of business process information for organizational process an...

The autonomic workflow engine enables workflow to be dynamically specified and adapted using Event-Condition-Action rules. A new approach to autonomic execution of workflow processes based on matrix-based formulation was adopted that, together with the Petri net marking transition equation, provides a full dynamical description of a workflow system. We have built a workflow that models Traffic-...

SUMMARY Snakemake is a workflow engine that provides a readable Python-based workflow definition language and a powerful execution environment that scales from single-core workstations to compute clusters without modifying the workflow. It is the first system to support the use of automatically inferred multiple named wildcards (or variables) in input and output filenames. AVAILABILITY http:/...

Traditional Workflow Management Systems (WfMS) is hard to meet the requirements of the dynamic, flexible modern business process. In recent years, Web services technology has been developing. It’s not only makes the activity in workflow by Web services form, but also workflow itself is invoked by Web services, especially semantic web services technology is developing, which makes it possible to...

Current platforms fail to efficiently cope with the data and task heterogeneity of modern analytics workflows due to their adhesion to a single data and/or compute model. As a remedy, we present IReS, the Intelligent Resource Scheduler for complex analytics workflows executed over multi-engine environments. IReS is able to optimize a workflow with respect to a user-defined policy relying on cos...

This paper presents VSCE, the Visual Service Composition Environment, which is one of a main visual components provided by the GSiB (Grid-Service-in-a-Box) project. VSCE uses SWFL as its main workflow language and employs SWFL workflow engines to provide an enactment environment for the SWFL jobs created in VSCE. The employer and employee relationship between a VSCE client and a workflow engine...

BACKGROUND Workflow engine technology represents a new class of software with the ability to graphically model step-based knowledge. We present application of this novel technology to the domain of clinical decision support. Successful implementation of decision support within an electronic health record (EHR) remains an unsolved research challenge. Previous research efforts were mostly based o...
