Research And Application Of Workflow Technology And Network Operations Management System

The workflow is a core technology which realizes business process model business process high efficiency, business process integration. The research to workflow is not only good to business process standard,but also is used to find bad process which exist in business process. The workflow process is the rule of business process and the workflow process can does modle for enterprise whose information management system.The JobFlow is the notional extension of job. It is a job execution sequence by correlative jobs organized according to the dependency of these jobs. And it is a good solving project to achieve the automatization of job execution flow. JobFlow describing language is used to describe all kinds of jobs and the dependency of these jobs, and then JobFlow can be formed into JobNetwork, which was submitted into system for explaining, executing and controlling by server. Job manage system is located by corporation key tasks or especial requires of some trades, it is a kind of system software that is established on operation system. The main utility for operation system is to enforce the regulation of job and to provide a new mechanism to submit, schedule, execute and control jobs. It can make use of system resource, balance the charge of network and improve all performance of the system more efficiently.The author has joined in the Software Engineering Center of NPU from April 2002, participating in designing and development of a international cooperatingproject-Job Management System. On the basis of two-year-practice, theauthor has had a deep understanding on the architecture and realization methods of the Job Management System.The content of this articl is bellowing:This article mainly introduces the implementation and realization key technology of Job Management System based on JobFlow.lt fully analyzes the architecture of Job Management System, and every composing portion in frame structure is described in detail. It introduce a model function: Petri Net. It dissects the definition of job network, job network script, job network parameter and the impact of job network in a job manage system. It also introduces the method of design and implement the engine of JobManage System, the schedule of jobs and execution of jobs. In order to improve the imperfection of security in JobManage System, a whole security solution powered by Windows NT Operating System has been realized. Furthermore, a new Domain Security policy applies to deal with Domain module in NT platform especially.
