Educational process modelling with workflow and time Petri nets : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Computer Science at Massey University, Palmerston North, New Zealand [PDF]
The research presented in this thesis describes how to use workflow management technology to model educational processes with a time axis. As workflow management technology has been widely used in modelling business processes, it has the potential to ...

WfChef: Automated Generation of Accurate Scientific Workflow Generators [PDF]
Scientific workflow applications have become mainstream and their automated and efficient execution on large-scale compute platforms is the object of extensive research and development. For these efforts to be successful, a solid experimental methodology is needed to evaluate workflow algorithms and systems.

Heterogeneous Workflows in Scientific Workflow Systems [PDF]
Workflow systems are used to model a range of scientific and business applications, each requiring a different set of capabilities. We analyze how these heterogeneous approaches can be resolved, look at how existing workflow systems address this and present the solution in Discovery Net, which combines three levels of workflows, control, data and grid,

Effects of the Interactions Between LPS and BIM on Workflow in Two Building Design Projects [PDF]
Variability in design workflow causes delays and undermines the performance of building projects. As lean processes, the Last Planner System (LPS) and Building Information Modeling (BIM) can improve workflow in building projects through features that ...

Crowdsourcing complex workflows under budget constraints [PDF]
We consider the problem of task allocation in crowdsourcing systems with multiple complex workflows, each of which consists of a set of interdependent micro-tasks. We propose Budgeteer, an algorithm to solve this problem under a budget constraint.

Workflow Partitioning and Deployment on the Cloud using Orchestra [PDF]
Orchestrating service-oriented workflows is typically based on a design model that routes both data and control through a single point - the centralised workflow engine. This causes scalability problems that include the unnecessary consumption of the network bandwidth, high latency in transmitting data between the services, and performance bottlenecks.

A component-based product line architecture for workflow management systems [PDF]
This paper presents a component-based product line for workflow management systems. The process followed to design the product line was based on the Catalysis method. Extensions were made to represent variability across the process.

Security-sensitive tackling of obstructed workflow executions [PDF]
Imposing access control onto workflows considerably reduces the set of users authorized to execute the workflow tasks. Further constraints (e.g. Separation of Duties) as well as unexpected unavailabilty of users may finally obstruct the successful ...

Improving Scientific Workflow with Cloud Offloading [PDF]
Scientific workflow is a powerful tool to streamline and organize computational steps of scientific application. This paper presents Emerald, a system that adds sophisticated cloud offloading capabilities to scientific workflows. Emerald automatically offloads computation intensive steps of scientific workflow to the cloud in order to enhance workflow ...
