Abstract:
Both the remote access of various business systems and the communication adaptation are on their way to becoming the chief bottleneck in Workflow Management System.In accordance with the requirement of the different business interfaces,this paper proposes the creation of a heterogeneous Workflow Management System.Then,a communication adapter system is designed,which can accomplish the conversion of a series of protocols.Finally,the new adapter system is applied to the safety production platform,and it keeps the key business of the platform distributed,efficient,and uniform.Keywords:

The current workflow system strong coupled with the external application,to a large extent limited the external applications.A cooperation workflow management system model based on WebServices is designed,on the basis of this model,a mechanism on access agents between the workflow engine and the external application is established and a collaborative interface model based on access agents is designed to breakthrough the limitations of the majority of workflow engine and solve the interface operation to the heterogeneous environment.The model has good interoperability,flexibility and scalability.

Collaborative workflow management systems in logistic companies require strong information systems and computer support.These IT integration requirements have expanded considerably with the advent of ebusiness; utilizing web services for B2B (Business to Business) and P2P (Partner to Partner) e-commerce.This paper proposes service oriented model driven architecture for dynamic workflow changes and strategy for implementation of these changes by isolation of services and business processes where by existing workflow systems can easily incorporate and integrate the changes following a step by step process replacement synchronization in workflow.This paper will also describe conceptual framework for prototype implementation resulting in dynamic collaborative workflow management.

It is an important problem how to make Web services to cooperate with each other using workflow technology. In this paper, an intelligent method is presented to generate a meta process according to users' requirements instead of pre-designing a rigid workflow model. This method is then implemented in our project - the intelligent platform of virtual travel agency, and results show high performance in Web services cooperation

On the basis of the research of workflow technologies and products in application environments,this paper presents a way to realize Web based workflow management system.All most all of the existing workflow products have some blemishes.Such as the model content is limited,can't satisfy diverse process request,feebleness scalable and flexible,the model can hardly to be expand,lacks support to distributed environment,redefinition is very difficult.The structure of the system and the design of its workflow engine model are also elaborated.Choose the J2EE development environment,use JBuilder 9.0 as developing language,adopt WebLogic 8.11 for applied server and the Oracle 9i is the best database of our work,build customer+ the Session Bean +CMP to make the many tiers framework.Develop an application system for water supplement enterprise.The new business system is reliable,efficient,convenient and easy to maintain.

This paper proposes the architecture and a model of business process support (BPS) systems for e-government organizational boundaries. Today, processes are mostly adapted to existing technologies; in contrast, the proposed architecture intends to support typical e-government processes. The proposed system consists of three main IT components: a workflow system for administration and control of information flows; Web services enabling data transfer between computers; and a Web server controlling all applications for communication with all users in each organization. The proposed model of the workflow enactment server consists of two nodes: the rule base collection, and the workflow engine. The workflow engine consists of two components A and B for process execution and control.

The information development process of modern enterprise operation and management has been gradually transformed from the traditional centralized management to distributed, heterogeneous approach. To adapt this sort of requirement, the workflow management system has changed the original goal of creating the paperless office environment to the target of performing business processes automatically. For the purpose of optimizing business process, in this paper, we present an enterprise-class workflow management system that use the N-TIER architecture technology on the J2EE platform (N-TIER-WORKFLOW System). This system which draws on the WFMC standards can be widely applied to various environment which need the support of process automation, such as office automation, ERP and integrated application.

Inter-Organizational business process coordination attempts to support the collaboration between different business processes, distributed over different enterprises. In order to coordinate the business processes of different organizations, we need to efficiently integrate different organization's workflows to provide customized services. Cross-enterprise workflow which can streamline and coordinate business processes across organizations in dynamic Web environment provides a flexible solution. In order to address the problem of dynamic web service composition we have adopted an approach based on Service oriented Inter-organizational Workflow (SIW) along with an Agent Based Architecture. Our objective is to dynamically integrate the workflows and compose a workflow execution community customized to different workflow specifications. In our work, each of the agent capability is used to serve a particular service request and business processes are wrapped by service agents. Based on the user's need, the process agent contacts the service selection agents to find appropriate service agents, and then negotiates with the service agents about task execution.

Different from the traditional model, mobile workflow is a process in which one or more mobile instances migrate continuously and utilize local workflow service to execute their tasks. This paper introduces the mobile workflow management system and proposes the active service of mobile workflow. By using the theory of small world in society, a modeling mechanism based on business friend domain is proposed, which could improve the flexibility of workflow management system and is fit for building the service environment to meet the requirement of mobile instance.
