Workflow technologies are becoming pervasive in the area of space. They enable the execution of space business processes in distributed and ubiquitous computing environments. However, there are some problems such as cross-platform workflow which need to be solved urgently in space test and launch. Aiming at enhancing the efficiency of space test and launch, the distributed workflow engine model of the space test and launch based on JMX was designed. And the workflow engine routing control algorithm was proposed. At last, the performance of the workflow engine system was analyzed. The model was applied in a launch base successfully. The actual operation tests show that: the proposed design model was rational and effective. It enabled changing the engine process dynamically and enhancing the flexibility of the engine system. Furthermore, it enabled setting workflow engines according to the task and application of the test and launch departments. The performance and efficiency of the space test and launch system was improved greatly.

Abstract This paper describes a model of modular system for Rapid Application Development of Web-based Information Systems (RADWIS). The existing modular systems on technology, framework and platform level does not fully solve the problems of functionality reuse, rapid application development and balance between the complexity, size and functionality. The proposed modular system addresses these problems in a new way. The current work fills the gap between the modular systems on the framework and platform level. The model uses flexible, reusable modules, which can be built with different technologies. They are installable and shareable with the standard dependency manager of the technology and can communicate using web services. The modules use NoSQL approaches in SQL databases. A workflow engine module, based on the Petri Nets theory, allows a graphical and formal mathematical solution for a wide variety of problems.

Distributed workflow technology has been widely used in modern education and e-business systems. Distributed web applications have shown cross-domain and cooperative characteristics to meet the need of current distributed workflow applications. In this paper, the author proposes a dynamic and adaptive scheduling algorithm PCSA (Pre-Calculated Scheduling Algorithm) for a distributed student registration system in a transaction-intensive environment. In this algorithm, every workflow application is pre-calculated before deployed into the workflow engine to create priority lists for solution generating. The simulations illustrate that the algorithm has a preferable efficiency and fits the needs of the distributed student registration system.

This article presents a detailed implementation of the Corporate Environmental Management Information Systems (CEMIS) Next Generation platform of the IT-for-Green research project. The provided services within this platform are grouped based on the module to which they belong. These services will be the main realization of the workflows activities of the system's business processes. In the frame of this project, the Next Generation CEMIS will be developed, to integrate research concepts of current interest and investigate their feasibility through a prototypical implementation. In this paper the authors focus on two major components: the workflow engine implemented using State Chart XML (SCXML) and the Green Service Mall realized as a set of standardized Web Services.

Grid brings the power of many computers to scientists. However, the development of Grid-enabled applications requires knowledge about Grid infrastructure and low-level API to Grid services. In turn, workflow management systems provide a high-level environment for rapid prototyping of experimental computing systems. Coupling Grid and workflow paradigms is important for the scientific community: it makes the power of the Grid easily available to the end user. The paradigm of data driven workflow execution is one of the ways to enable distributed workflow on the Grid. The work presented in this paper is carried out in the context of the Virtual Laboratory for e-Science project. We present the VLAM-G workflow management system and its core component: the Run-Time System (RTS). The RTS is a dataflow driven workflow engine which utilizes Grid resources, hiding the complexity of the Grid from a scientist. Special attention is paid to the concept of dataflow and direct data streaming between distributed workflow components. We present the architecture and components of the RTS, describe the features of VLAM-G workflow execution, and evaluate the system by performance measurements and a real life use case.
