WF Based Early Warning Processing Automated System

The Workflow technology has gradually played an increasingly important role from appearing to now. It mainly used to solve the business problems. Workflow provides business process modeling, management and control functions for enterprise applications, and it can be used in electronic government, the one-stop office, the e-business process integration business credit and financial fields, as the recent rapid growth in the area. The early warning processing automated system achieves flow process and automation of early warning analysis and diagnosis of process by workflow technology.This thesis introduces the basic concept of workflow and Microsoft Windows Workflow Foundation at first, and the latter is the workflow solution as component of WinFX developed by Microsoft Corporation recently. The thesis uses the APIs and the tools of WF to design and develop the application based on workflow. Because the WF provided an united workflow model, the early warning processing automated system establishes End-to-End solution which crosses over several types of application, including human workflow and system workflow.This thesis discusses the workflow system and human-interactive business process model. The main body that Workflow concerns is process. The workflow extracts the process dealing with information, and studies its structure, nature and realization. Its main solution is "to automate the process which transfers documents, information or task according to a predefined rule among several participants, thus achieving desired business goals, or to promote the realization of this objective." This makes the workflow will transfer appropriate messages to the appropriate persons at the appropriate time, using the appropriate tools to handle. Workflow has a number of interactive points, or agreements. Either first aid process or the approval process, which providing the crucial business value is "collaboration". As examples of business processes are "long-term", often in days, weeks or months rather than minutes for the metric units, for example, the processing work, thus the thesis discusses the persisting service that the WF provides saving the workflow to a state database. Because there are a number of "human" participants in the early warning processing automated system, the thesis discuss interaction between the workflows and clients.
