Abstract


A workflow is developed in the 1990s, a reflection of a computerized model of the business process is in an advanced computing environment in order to achieve the support of business process integration and business process automation and workflow management system established by the execution of the business model. Workflow technology in the commercial, scientific computing, grid computing and other fields have a wide range of research and application. With the application of workflow technology and development, it was discovered that the current workflow model and its visual modeling tool supports only static, horizontal business process definition and modeling, and not based on multiple workflow instances running conditions common characteristics modeling to achieve vertical direction to dynamically optimize process execution and modify its preparation, control and data information. To solve this problem, we can learn from the aspect-oriented (Aspect-oriented) programming the basic idea, a new instance-based work flow expansion model, which can effectively describe the same type of activity more workflow activity instance combination treatment problems and achieve vertical modeling, respectively, so that the original multiple workflow instances running at the implementation level of dynamic combinatorial optimization execution, without affecting the user's view of the workflow static and dynamic operation monitoring view. Workflow visual modeling tool using a graphical user interface, GUI, by manually dragging the icons way to create a workflow visualization model expression, the last automatically generated workflow definition language. Using graphical methods, modelers can use the least amount of time designing or modifying business workflow, enhance work efficiency. Traditional workflow visual modeling tool a lot, but they do not support the vertical aspects of the workflow instance modeling. In this thesis, the open source workflow management system modeling tool Together workflow Editor Shark build on and extend the study to support aspects of the workflow instance model representation and operation principles of visual modeling tools, methods and implementation. Innovation and main thesis work: 1. Workflow modeling tool Together Workflow Editor profiling. 2 Based Together Workflow Editor, expressed support for instance aspect model workflow modeling tool overall frame design. 3 aspects of the workflow instance model visualization. 4 Application object-oriented aspects of workflow instances modeling tool implementation.
