Workflow management systems (WfMSs) automate and manage workflows, which are implementations of organizational processes operated in process-centric organizations. In this paper, wepropose an algorithm to discover temporal work transference networks from workflow execution logs. The temporal work transference network is a special type of enterprise social networks that consists of workflow performers, and relationships among them that are formed by work transferences between performers who are responsible in performing precedent and succeeding activities in a workflow process. In terms of analysis, the temporal work transference network is an analytical property that has significant value to be analyzed to discover organizational knowledge for human resource management and related decision-making steps for process-centric organizations. Also, the beginning point of implementinga human-centered workflow intelligence framework dealing with work transference networks is to develop an algorithm for discovering temporal work transference cases on workflow execution logs. To this end, we first formalize a concept of temporal work transference network, and next, we present a discovery algorithm which is for the construction of temporal work transference network from workflow execution logs. Then, as a verification of the proposed algorithm, we apply the algorithm to an XES-formatted log dataset that was released by the process mining research group and finally summarize the discovery result.

Collaborative system is an essential idea in the global and e-business environments Workflow plays a key role implementing collaborative system. Workflow is an emerging technology for business process automation, monitoring integrity enforcement, and recovery. A process model describes the structure of business process in the real world The process model can be transformed into a Workflow model utilizing a computer. The paper proposes a web-based Workflow process design in the B2B environment Considering a global environment where the partners interchange their processes beyond the company boundaries, a web-based infrastructure is the most preferred platform Considering this, Workflow processes and e-Business structures were combined together on the web environment.

Workflow composition and management is a crucial part of Component Based Development (CBD). Workflows can be composed reusing existing workflows to improve efficiency during the various stages of software development process. Reusability of software process activities is improved by using existing workflows. This paper proposes a Workflow Composition Engine that generates workflow which consists of existing process activities and describes design of The Workflow Composition Engine. A prototype of the Workflow Composition Engine implemented is described.

This paper theoretically derives an algorithm to discover a new type of workflow-based knowledge from workflow models, which is termed workflow-based affiliation network knowledge. In general, workflow intelligence (or business process intelligence) technology consists of four types of techniques that discover, analyze, monitor and control, and predict a series of workflow-based knowledge from workflow models and their execution histories. So, this paper proposes a knowledge discovery algorithm which is able to discover workflow-based affiliation networks that represent the association and participation relationships between activities and performers defined in ICN-based workflow models. In order particularly to prove the correctness and feasibility of the proposed algorithm, this paper tries to apply the algorithm to a specific workflow model and to show that it is able to derive its corresponding workflow-based affiliation network knowledge.

Due to the development and proliferation of internet technology, cooperation and interaction between companies have become very important. However, different heterogeneous systems have been used as information systems for companies because of various types of pressure in the business environment. Therefore, business process integration and interaction are recognized as essential elements, not optional elements. In addition, it is important to make a business process which is valuable as an intellectual property in a storable form and share. So, many business process languages for service integration and GUI type's automatic systems using the same and making business process easily have been introducing. However, to integrate previously created web service[1] workflows, or to use a web service workflow for another workflow production like an activity, that is, research to support multi integration language and system is not ongoing except for research to make and connect adapter between workflow engines.[2] Also, research for current languages and systems that integrate the BPEL[3] process into a workflow in the industrial world does not exist. This means that integration between workflows being used at companies is difficult, and becomes the biggest obstacle to service integration, which is necessary for cooperation and interaction between companies. To solve this problem, in this paper, I defined BPIL based on XML[4], which can store business processes. Also, using this, BPIL workflow system based on SOA[5] which supports multiple integration and workflow profiling was designed and prototype was embodied.

According to increasing necessaries of workflow systems, it will be useful to most Enterprises. However existing workflow systems are shared only inside of systems that use a same process definition. It is difficult to share a process definition with another enterprise using different platforms. In this paper, we used Web Service for sharing process definition. Web Service have advantage that can linked between different platforms. Therefore we developed workflow Process definition by using Web Service. Using Web Service, we can be share workflow process definition between enterprises using different platform.

A Workflow Management System is one which provides procedural automation of a business process by management of the sequence of work activities. The existing workflow management systems have limitation of interaction among application systems. In this paper, we propose a new workflow management system that can be adapted in dynamically changed paradigm of distributed computing by using Web Service. System Architecture and prototyping execution model of the system is described in BPEL4WS.

□ Many specification language has been developed for workflow modeling, but their emphasis on the process semantics make it difficult for use on the business process modeling. □ Also their lack of understanding of global view of Business process adds another problem to model workflow in a seamless and accurate and timely fashion(omitted)

A workflow management system is a software system to support accurate execution, control and management of business processes. It has been known that the system automatically executes complex processes and effectively manages them to improve the productivities. However though existing systems assure the automatic execution of an individual process, there is a room for enhancement from the view of efficient execution of all the processes. In this paper, we propose a method of executing business processes efficiently by introducing the PERT/CPM techniques in the workflow management systems. We first consider the differences between workflow process models and PERT/CPM models, and then develop a method of calculating the critical path and slack time in workflow processes. This leads us to develop a dispatching rule that can guide task performers to prioritize their tasks to increase the efficiency of ail the processes. We have carried out a set of simulation experiments and analyzed the results to demonstrate the effectiveness of the proposed method.

To realize process-driven management, so many companies have been launching business process managementsystems. Business process is collection of standardized and structured tasks inducing value creation of acompany. Moreover, it is recognized as one of significant intangible business assets to achieve competitiveadvantages. This research introduces a novel approach of workflow process analysis, which has more and moresignificance as process-aware information systems are spreading widely into a lot of companies, In this paper, amethodology of workflow clustering based on process similarity has been proposed. The purpose of workflowclustering is to analyze accumulated process definitions in order to assist design of new processes andimprovement of existing ones. The proposed methodology exploits measures of structural similarity of workflowprocesses.The methodology has been experimented with synthetic process models for illustrating the implicationofworkflow clustering.
