Since business workflows are closely related to enterprise performance, successfule execution of workflow is a critical driving force for strategic advantages of enterprise. Therefore, it is quite essential to customer satisfaction and productivity enhancement that structural errors in workflow instances must be detected and their performance must be evaluated before their enactments. For a str...

A collection of user interface design patterns for workflow information systems is presented. Each Workflow User Interface Pattern (WUIP) is characterized by properties expressed in the PLML markup language for expressing patterns and augmented by additional attributes and models attached to the pattern: the abstract user interface and the corresponding task model. These models are specified in...

T n ( b bstract: Confronted with changing environments, dynamicity is inevitable and business rocesses are characterized by indefiniteness, which requires that workflow systems should be lexible and dynamic. Most of current workflow systems are activity-based, paying little ttention to people and their roles. However, it is noteworthy that ignore of roles maybe one of he main reasons for lack o...

The goal of workflow mining is to obtain objective and valuable information from event logs .The research of workflow mining is of great significance for deploying new business process as well as analyzing and improving the already deployed ones. Many information systems log event data about executed tasks. Workflow mining is concerned with the derivation of a graphical process model out of thi...

Workflow management systems support an efficient, largely automated execution of business processes. If a workflow management system is used to implement a computer supported business process from scratch, all the functionality of the workflow management system can be fully exploited. In particular, the control flow will be completely specified in the workflow management system’s specification ...

A workflow system defines, creates and manages the execution of business workflows with workflow engines, which interpret workflow definitions, and interact with task performers. As most of non-trivial organizations have massive amount of workflows to process simultaneously, there is ever-increasing demands for better performance and scalability of workflow systems. This paper proposes a workfl...

Web services workflows are increasingly gaining attention. With the advent of emerging standards such as the Business Process Execution Language for Web Services (BPEL4WS) medical organizations are investigating the options for modeling ad-hoc workflows. In this paper we analyze a highly relevant ad-hoc workflow in the medical imaging domain: the second opinion workflow. Since this workflow, by...

Grid computing is becoming a mainstream technology for large-scale distributed resource sharing and system integration. Workflow management is emerging as one of the most important grid services. In this work, a workflow management system for grid computing, called GridFlow, is presented, including a user portal and services of both global grid workflow management and local grid sub-workflow sc...

Current manufacturing industry requires product data management (PDM) for efficient product development and production. As an important part of effective PDM solutions, workflow management facilitates creating and executing workflow so as to streamline business processes. Unfortunately, existing workflow management solutions are designed to handle static business processes; when a workflow chan...
