We propose the role-and-relation-based access control (R2 BAC) model for workflow systems. In R2 BAC, in addition to a user's role memberships, the user's relationships w...
: General purpose workflow management systems are often unable to match user requirements of a particular application. In many points of the workflow the user has to take decisions...
Workflows systems are considered here to support largescale multiphysics simulations. Because the use of large distributed and parallel multi-core infrastructures is prone to soft...
Workflows are activities involving the coordinated execution of multiple tasks performed by different processing entities, mostly in distributed heterogeneous environments which a...
