Proposed in this paper is a standard-compliant business process modeling tool which is based on the UML(Unified Modeling Language) activity diagram and produces an XPDL(XML Process Definition Language) file as an output. The XPDL is a standard process definition exchange format by WfMC (Workflow Management Coalition). To develop an UML/XPDL-based modeling tool, the mapping of modeling elements between activity diagram and XPDL format is conducted after the detailed analysis of each modeling specification. As a result of this mapping, it is revealed that modeling elements of each activity diagram and XPDL must be expanded. So new modeling elements are identified and added to each specification. Based on this mapping, the prototype system is developed, and the usefulness of the developed system is shown through the case study.

XPDL is a XML-based language for process definition exchange that is proposed by WfMC. This paper propose a model which model XPDL document structure (Schema) using UML in order to define and to exchange workflow process, and make business flow understanding ease for inter-business cooperation. So, we define mapping rules in which map XPDL documents into UML class diagram and UML activity diagram. By these mapping rules, elements composing XPDL process meta-model are mapped into UML class diagram, and process activities are mapped into UML activity diagram. Also, we apply proposed mapping technique to model a workflow of (')Credit card state check system.(')

Recently, many enterprises are introducing a workflow management system for the successful implementation of BPR(Business Process Reengineering). Proposed in this study is the workflow management system which has a light-weight component structure and an XPDL(XML Process Definition Language) file interpretation facility. The XPDL is the standard process definition exchange format developed by WfMC(Workflow Management Coalition). The major causes of inefficiency at current implementations of workflow management systems are the centralized workflow engine structure and the use of proprietary workflow definition format among most solutions. The proposed light-weight component structure in this study is the intermediate structure that takes the strength of both centralized and distributed workflow engines. And a prototype workflow system which uses an XPDL process definition file as input is developed through the thorough analysis of functional requirements.

Currently there are a variety of different tools may be used to analyze, model, describe and document a business process. However, it is difficult to exchange the information of a business process created in different tools because of the distinct information formats used in different tools. The XML Process Definition Language (XPDL) of the Workflow Management Coalition (WfMC) forms a common interchange standard that enables products to continue to support arbitrary internal representations of process definitions with an import/export function to map to/from the standard at the product boundary. Generally a business process model can be represented by the UML activity diagram, but there is a difficult task to directly generate an XPDL document from a business process model represented by the standard activity diagram. In the paper we will propose an approach to generate an XPDL document from a business process model represented by the extended UML activity diagram.

In recent, workflow technology has been spotlighted in the literature, according for e-business processes and their automations to be taken important and essential parts into account in the enterprise information processing environment, because the workflow technology ought to be an impeccable solution for automating the e-business processes. When we analyze and model e-business processes in an enterprise, it is very important to verify and validate the e-business processes before they are deployed on the real business environment. Especially, it should be very worthy for the verification and validation work to be done by a kind of graphical visualization approaches. This paper propose a business process enactment animator implemented by Java Technologies. And it supports WPDL(Workflow Process Definition Language) as well as XPDL(XML-Based Process Definition Language), both of which are the standard specification language by WfMC that is the international standardization organization for Workflow Technology.

In this paper, we describe the design details and their implementation of a workflow model (or business process model) analysis system to be used for enhancing resource allocation efficiency and operational performance of enterprise workflows. In other word, the analysis works, proposed in this paper, on XPDL-based workflow models aim to verify the static aspects of the workflow models. Also, the system implemented in the paper is able to not only analyze structural patterns and resource allocation plans' efficiency of enterprise workflows modeled by the XPDL process definition language developed by the international standardization organization, WfMC, but also provide various forms of analytical reports. Conclusively, we strongly believe that the workflow analysis system developed in the paper enables workflow modelers to not only analyze and scrutinize structural patterns of their workflow models but also estimate their process resources assigning and planning measurements in order to improve accuracy, reliability and efficiency of enterprise workflows.

A workflow process (or business process) management system helps to define, execute, monitor and manage workflow models deployed on a workflow-supported enterprise, and the system is compartmentalized into a modeling subsystem and an enacting subsystem, in general. The modeling subsystem's functionality is to discover and analyze workflow models via a theoretical modeling methodology like ICN, to graphically define them via a graphical representation notation like BPMN, and to systematically deploy those graphically defined models onto the enacting subsystem by transforming into their textual models represented by a standardized workflow process definition language like XPDL. Before deploying those defined workflow models, it is very important to inspect its syntactical correctness as well as its structural properness to minimize the loss of effectiveness and the depreciation of efficiency in managing the corresponding workflow models. In this paper, we are particularly interested in verifying very large-scale and massively parallel workflow models, and so we need a sophisticated analyzer to automatically analyze those specialized and complex styles of workflow models. One of the sophisticated analyzers devised in this paper is able to analyze not only the structural complexity but also the data-sequence complexity, especially. The structural complexity is based upon combinational usages of those control-structure constructs such as subprocesses, exclusive-OR, parallel-AND and iterative-LOOP primitives with preserving matched pairing and proper nesting properties, whereas the data-sequence complexity is based upon combinational usages of those relevant data repositories such as data definition sequences and data use sequences. Through the devised and implemented analyzer in this paper, we are able eventually to achieve the systematic verifications of the syntactical correctness as well as the effective validation of the structural properness on those complicate and large-scale styles of workflow models. As an experimental study, we apply the implemented analyzer to an exemplary large-scale and massively parallel workflow process model, the Large Bank Transaction Workflow Process Model, and show the structural complexity analysis results via a series of operational screens captured from the implemented analyzer.

Recently, the importance of visual analytics has been recognized in the field of business intelligence. From the view of business intelligence, visual analytics aims for acquiring valuable insights for decision making by interactively visualizing a variety of business information. In this paper, we propose a treemap-based method for visualizing work-sharing relationships among business process performers. A work-sharing relationship is established between two performers who jointly participate in a specific activity of a business process and is an important factor for understanding organizational structures and behaviors in a process-centric organization. To this end, we design and implement a treemap-based visualization tool for representing work-sharing relationships as well as basic hierarchical information in business processes. Finally, we evaluate usefulness of the proposed visualization tool through an operational example using XPDL (XML Process Definition Language) process models.
