The design and operation of autonomous agents to assure information in ERP systems of inter-networked enterprises are investigated. A variable information assurance implementation model is proposed based on the AIMIS model, and a risk assessment procedure is applied. The protocols and models needed

constraints is crucial in designing and managing business processes. Consequently, time management should be part of the core management functionality provided by workflow systems to control the lifecycle of processes. At build-time, when workflow schemas are developed and defined, workflow modelers need

The automated tracking and storage of provenance information promises to be a major advantage of scientific workflow systems. We discuss issues related to data and workflow provenance, and present techniques for focusing user attention on meaningful provenance through “user views,” for managing

This paper will discuss some of the basic assumptions behind office work and scientific work, and show that workflow systems for these two endeavors should have different functionalities. In particular we discuss the idea that data management and management of workflow models are the most

The specification and enforcement of authorization policies such as separation of duty and binding of duty in workflow systems is an important area of current research in computer security. We introduce a formal model for constrained workflow systems that incorporate constraints for implementing

Abstract: Reusable development can promote the productivity of large workflow systems development. However it has not precluded developers from designing workflow system tailoring to users ’ specific needs, though workflow management coalition standardized the five kinds of abstract interfaces

by successfully separating the access of data from the applications. However, any change and enhancement to the business policies would entail modifying application code, as the business policy is still mainly hard-coded [ED97]. Workflow systems are a step in the direction in providing both automation

In a workflow system, autonomous agents perform various activities cooperatively to complete a common task. Successful completion of the task often depends on correct synchronization and scheduling of agents ’ activities. It would greatly enhance the capabilities of current workflow systems

to evaluate the acceptance of technology is the actual usage of the system [6],[5]. Also when studying groupware, the implementation of the system is often considered as successful if there is a critical mass of regular users [18]. When studying workflow systems however, usage is not optional. Reluctance

commercial workflow technology and extend the scope and mission of workflow management systems to support increased workflow automation in complex real-world environments involving heterogeneous, autonomous, and distributed information systems. In particular, we discuss how distributed object management
