Time Constraints in Workflow Systems
- In Proc. of the 11 th International Conference on Advanced Information Systems Engineering (CAiSE’99), Springer Verlag, LNCS 1626
, 1999
"... . Time management is a critical component of workflow-based process management. Important aspects of time management include planning of workflow process execution in time, estimating workflow execution duration, avoiding deadline violations, and satisfying all external time constraints such as fixe ..."

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
Provenance in scientific workflow systems
"... 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 the ..."

"... 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 importa ..."

On the Satisfiability of Constraints in Workflow Systems
, 2004
"... 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 suc ..."

Study of the Reusable Workflow System
"... 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 of wo ..."

1. What are Workflow Systems? Security for Workflow Systems
"... Organizations constantly reengineer and optimize their business processes to reduce costs, deliver timely services, and enhance their competitive advantage in the market. Reengineering involves assessment, analysis, and redesign of business processes, including introducing new processes into existin ..."

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
An Overview of Workflow Management: From Process Modeling to Workflow Automation Infrastructure
- DISTRIBUTED AND PARALLEL DATABASES
, 1995
"... Today’s business enterprises must deal with global competition, reduce the cost of doing business, and rapidly develop new services and products. To address these requirements enterprises must constantly reconsider and optimize the way they do business and change their information systems and appl ..."

In particular, we discuss how distributed object management
Temporal reasoning in workflow systems
- Distributed and Parallel Databases
"... 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 if quant ..."

Satisfiability and Resiliency in Workflow Systems
"... Abstract. We propose the role-and-relation-based access control (R 2 BAC) model for workflow systems. In R 2 BAC, in addition to a user’s role memberships, the user’s relationships with other users help determine whether the user is allowed to perform a certain step in a workflow. For example, a con ..."
