Analysis of a collaborative Workflow Process with distributed actors
Information Systems Frontiers, 2008Co-Authors: Hajo A. Reijers, Minseok Song, Byungduk JeongAbstract:Current Workflow management technology offers rich support for Process-oriented coordination of distributed teamwork. In this paper, we evaluate the performance of an industrial Workflow Process where similar tasks can be performed by various actors at many different locations. We analyzed a large Workflow Process log with state-of-the-art mining tools associated with the ProM framework. Our analysis leads to the conclusion that there is a positive effect on Process performance when Workflow actors are geographically close to each other. Our case study shows that the use of Workflow technology in itself is not sufficient to level geographical barriers between team members and that additional measures are required for a desirable performance.

evaluating Workflow Process designs using cohesion and coupling metrics
Computers in Industry, 2008Co-Authors: Irene Vanderfeesten, Hajo A. Reijers, Wil M P Van Der AalstAbstract:Building on the similarities between software programs and Workflow Processes, this paper proposes a heuristic that offers guidance for the creation and evaluation of Process designs in administrative settings. Designers can use this heuristic to select from several alternatives the Process design that is strongly cohesive and weakly coupled. It is argued that such a design will result in fewer errors during information exchanges and in more understandable activity descriptions. The paper includes an application of the heuristic in an industrial Workflow setting, which supports its feasibility and practical value. The paper also presents the freely available CoCoFlow tool that implements the heuristic and its associated metrics.

CAiSE - Product Based Workflow Support: Dynamic Workflow Execution
Notes on Numerical Fluid Mechanics and Multidisciplinary Design, 2008Co-Authors: Irene Vanderfeesten, Hajo A. Reijers, Wil M P Van Der AalstAbstract:Product Based Workflow Design (PBWD) is a successful new approach to Workflow Process support. A description of the product, the Product Data Model (PDM), is central to this approach. While other research so far has focused on deriving a Process model from the PDM, this paper presents a way to directly execute the PDM. This leads to a more dynamic and flexible support for the Workflow Process.

intelligent tools for Workflow Process redesign a research agenda
Lecture Notes in Computer Science, 2006Co-Authors: Mariska M Netjes, Irene Vanderfeesten, Hajo A. ReijersAbstract:Although much attention is being paid to business Processes during the past decades, the design of business Processes and particularly Workflow Processes is still more art than science. In this workshop paper, we present our view on modeling methods for Workflow Processes and introduce our research aiming for the development of an intelligent software tool for Workflow Process redesign. This tool uses two approaches to redesign Workflows: an evolutionary approach, focussing on local updates to a given Process, and a revolutionary approach, starting with a clean-sheet of paper.

Workflow Process definition tool based on reuse-PDTBR
Journal of Computer Applications, 2009Co-Authors: Hao Ke-gangAbstract:An approach to define Workflow Process on the basis of reuse was proposed in order to improve its efficiency. The Process for producing and describing the reusable assets, domain business ontology and Workflow template were presented here. Moreover, a Workflow template retrieval method based on domain business ontology was stated. A reuse-based Process definition tool was developed as a result. It has demonstrated that the approach is feasible and more productive in application.

Research on dynamic simulation of Workflow Process
Computer Engineering and Applications, 2009Co-Authors: Hao Ke-gangAbstract:The mode to capability analysis and correctness verification of Workflow Process is divided in static inspection and dy-namic simulation.Especially the paper studies several key problems in Process simulation,setting up simulation enviroment,the al-gorithm for arranging events in a queue based on path coverage rule,analyzing simulation results.It adopts interactive and non-interactive means,employs white-box and black-box methods to test Workflow Process based on high coverage rate.And at last it gives expression to type,distribution and trend of Process defects.

Workflow Process Definition Reuse Method in Software Product Line Architecture
Computer Science, 2009Co-Authors: Hao Ke-gangAbstract:There is a problem in practical application of Workflow management system.It is that the Workflow Processes have been defined with a low efficiency and productivity due to the complexity of actual business Processes.An approach to this problem was proposed by adopting the idea and technique of software reuse.The solution is based on the architecture of software product line and aims to improve the efficiency of the domain-specific Workflow Processes' definition.Two types of reusable assets,domain business ontology and Workflow template,were identified.Moreover,how to construct,describe and retrieve these reusable assets was discussed in detail.The steps to define the Workflow Process based on reuse were explained.As a demonstration,a definition tool was developed and the method was proved feasible and more productive in practice.

Research and Application of an XML-based Workflow Process Definition Language
Computer Engineering, 2005Co-Authors: Liu Hai-lingAbstract:This paper presentes an XML-based Workflow definition language named XML-WfPDL to describe the Workflow Process model,deriving from the advantages of the XPDL of WfMC and XML. This language separates Workflow Process definition from Workflow executionengine, so it may make the Workflow definition language flexible enough to adapt to web and the heterogeneous application environment. And then,it also introduces design idea, main concept and related realization technology of XML-WfPDL. At last, it gives an example of a networkexamination and approval system based on XML-WfPDL.

cohesion and coupling metrics for Workflow Process design
Business Process Management, 2004Co-Authors: Hajo A. Reijers, Irene VanderfeestenAbstract:Workflow designers experience considerable freedom in designing the smaller steps (or activities) within a Process. An operational notion of activity cohesion and coupling may help them to design more well-structured Workflow activities. Inspired by resemblances between software programs and Workflow Processes, this paper gives an overview of software quality metrics and their applicability to Workflow Process design. New cohesion and coupling metrics – inspired by these software metrics – are introduced, which are integrated in a design heuristic. This heuristic can be used by Workflow designers to identify the strongly cohesive and weakly coupled Process design among several alternatives. The paper includes an application of this heuristic in a realistic Workflow Process setting.
