Research On Process Meta Object And Its Behavior

With the advancement of technology, increasingly complex business needs, the modify of business process has become even more frequent. Information systems are developing toward context awareness, demand, and scalable model-driven direction. Though there are many model-driven workflow management system, but "stiff" problem of process is still exists. Process cannot change with the needs and context change.The calculating object has been developed from the traditional object to the components, and to the current "service" as the calculation target. The calculating objects have been more and more complex, but the objects are encapsulated from three dimensions of the data structure, interfaces, and behavior. It is necessary to encapsulate a process object to make the process adaptable. In this paper, the process object is shown which is encapsulated from the logical structure of process meta-model, the process behavior semantic and the process interface for process objects.Basic operation model includes add, delete and modify. Based on the definition of a directed graph, all basic evolution atomic operations of directed graph will be shown in this thesis. Process complex operations can be achieved according to the evolution of these permutations and combinations of atomic operations. In the meta-model layer, depending on the process meta-model elements and their attributes, the basic evolution process operations are listed. Specific process models are the instances of meta model, so these evolution operations are also applied to the process model. Evolution operations in model layer include the modifications of process structure and nodes. The evolutions operations of process instances are mainly include modifications to the node attributes.In this paper, the configurable BPMN is as an example to analysis the configurable behavior semantic. This paper defines the BPMN meta-model and semantics of configurable process. The configurable behavior of process can be defined by the process behavior semantics.
