Abstract


Early nineties workflow technology to the enterprise application provides a horizontal integration capabilities, to this day, workflow technology is still not perfect. Enterprises are faced with complex and changing environment, business processes in the actual implementation is often not possible to determine its execution logic, requiring the process runs with dynamic capacity, which is now the problem is flexible workflow technology is facing problems. Flexible modeling will assist the optimization of business processes play an important role in the development of a flexible flexibility to quickly adapt to changing business process modeling is an important new topics. Through in-depth study of existing modeling methods, flexible modeling, workflow management systems design and we have yet to solve the problem of flexibility to design a flexible component-based modeling approach and flexible workflow management system. Flexible component-based modeling approach to workflow activities are divided into three types: ordinary activities, static and dynamic component members. The members are divided into static and dynamic components components while meeting aims to manually select the static components and the system automatically selects the dynamic component needs. Dynamic and static member in its own component is not running before can be modified at run time to be reflected with greater flexibility. In the event attribute type and constraints added two properties, which constraints are an important component of dynamic properties and constraints are discussed in detail. Particularly in order to be able to handle all process sequence, the combination of constraints in a dynamic component in the design of additional conditions for the act or branching and aggregation type of activity or selection process conditions. Dynamic component to automate the design of a run is because according to constraints to dynamically generate the required components of the algorithm, and verify that this method can make the activities of the dynamic component library activities at run time with the highest concurrency, can be most fast completion member task. Workflow Management Coalition proposed workflow management system architecture flexibility is difficult to deal with the problem, this is carried out for the component-based workflow management system design. The component-based workflow management system, including search engines, perform searches of various components; also includes component library. Member may be used again a workflow component modeling can save unnecessary duplication; obtained through the search query interface member can then be used again. Concludes with a discussion of the subject device institute management system based on workflow management subsystem design, by adding the required attributes to be added to the component design modeling tool design, and gives the workflow management subsystem application examples .
