The paper addresses the problem of flexible workflow Management systems (WFMS) in distributed environment. Concerning the serious deficiency of flexibility in the current workflowsystems, we describe how our FlexFlow workflowsystem meets the requirements of interoperability, scalability, flexibility, dependability and adaptability. With an additional route engine, the execution path will be adjusted dynamically according to the execution conditions so as to improve the flexibility and dependability of the system. A dynamic register mechanism of domain engines is introduced to improve the scalability and adaptability of the system. We describe functionalities, collaborations and process state diagrams of our system. The system is general purpose and open: it has been designed and implemented as a set of CORBA services. The system serves as an example of the use of middleware technologies to provide a fault-tolerant execution environment for long running distributed applications. The system also provides a mechanism for communication of distributed components in order to support inter-organizational WFMS.

Using a database management system ( DBMS) is essential to ensure the data integrity and reliability of large, multidimensional data sets. However, loading multiterabyte data into a DBMS is a time-consuming and error-prone task that the authors have tried to automate by developing the sqlLoader pipeline - a distributed workflow system for data loading.

The distributedworkflow is one of the main study fields of collaboration office automation, however, the traditional technique limits its realization. The emergence of Service-oriented Architecture technology provides a frame which can suffice the requirements of different structure, being independent of language and transparent service for distributed applications and overcomes the deficiency of traditional workflow distributing applications solutions. This paper presents a model of secure distributed workflow system and realization based on web service technology which meets the requirements of collaboration office automation between enterprises. The paper concluded with a successful realization in Chongqing electronic power.

Credit is the important foundation of Market Economy. Essentially, Market Economy is Credit Economy. Based on ebXML framework & distributed workflow system, credit risk evaluation & management system will be published as services to ebXML registry and repository system. For Credibility E-commerce, the operation model has been promoted It consists of five parts: client enterprise A, client enterprise B, ebXML registry and repository system, CA system, and credit risk evaluation & management system. There are three key techniques about Credibility E-commerce, the distributed workflow system, the credit service system, and the ebXML framework. The ebXML-based credibility e-commerce system has been used to provide service for an international trade enterprise of China.

In this paper, we describe a distributed transactional workflowsystem named ICU/COWS, which supports multiple workflow types of large scale enterprises. The system aims to support the whole workflow for large scale enterprises effectively within a single workflowsystem and the system is designed to satisfy several design goals such as availability, scalability, and reliability. Transactional task and special tasks such as alternative task and compensating task are developed and utilized to achieve the design goals in task model level and the system is constructed with distributed transactional objects to achieve the design goals in distributedsystem environment. In this paper, structured ad hoc workflow is defined as a special type of ad hoc workflow that should be automated by workflow management system because many benefits can be obtained by automating it and connector facility is proposed as a means to support structured ad hoc workflow effectively. Some characteristics of a workflowsystem can be identified by monitoring the system behavior on different conditions like workloads or system configurations. An early version of the system has been implemented and the performance data of the system is illustrated.
