Policy Based Network Management has been presented as a paradigm for efficient and customisable management systems. The IETF has provided a framework to describe the concept but some aspects still open like transactional control. In fact transactional control mechanisms are receiving today great attention in the scope of network management. In here, we identify the lacks of current management p...

This paper provides a contribution to qualitative reasoning for continuous process supervision. Tools for formalizing empirical knowledge of continuous processes and a naive reasoning nat­ urally integrating perception are proposed. A new paradigm emerges : maintenance of a single instantaneous and possibly partial understanding of a physical system during its evolution. This understanding in c...

The focus of traditional workflow management systems is on control flow within one process definition. The process definition describes how a single case (i.e. workflow instance) in isolation is handled. For many applications this paradigm is inadequate. Interaction between cases to support communication and collaboration is at least as important. This paper introduces and advocates the use of ...

Access control administration is a huge task. Administration tools should assist the administrator in ensuring that the access control requirements are met. One example of an access control requirement is Separation of Duty (SoD). SoD requirements specify that no single person may have sufficient authority to complete a business process unilaterally. The SoDA prototype administration tool has b...

This paper presents a generic programmingparadigm, called the control plan paradigm, based on Nested Finite State Machines (NFSMs) and event-driven mechanisms. In this paradigm, a control program can be divided into two non-overlapping parts: behavior and operation speciications. This division allows machine-dependent and machine-independent control programs to be designed and implemented indep...
