The Workflow Management System Based On Web Technology And Plm Platform Research And Design Of Software

With the rapid development of computer technology, network technology, digital management and paperless office has been widely infiltrated into all aspects of society, especially enterprise management field.Workflow management system will eventually become the business operating system which covered in various types of desktop and network operating system, but the workflow technology is still needed improvement and perfection. Based on a thorough study of the workflow management coalition workflow management system model and the major mainstream workflow management system design, the author has designed a set of overall architecture of workflow management system. This paper mainly from the system structure of the three levels deep and introduces the system structure.In this thesis, the enterprise development life cycle (PLM) platform for the development of the workflow management system to do deep research and the realization of its system design. Research contents:Workflow system based on PLM architecture analysis, workflow model, workflow authorization model and so on. Based on the paperless office which is In the development process, independent development of PLM integration system as the platform of workflow management system. The workflow management system based on B/S architecture, using Microsoft’s new.Net platform development, using industry-leading ASP.NET technology and C#language development, is not only safe and reliable, and can ensure the system is running high. This system uses the extension type three layer architecture which includes the database, business entity layer, data access layer, business logic layer, service agency and the interface layer, application layer. Data access layer using Nhibernate technology to support many kinds of database. The workflow system using improved VML graphic design, concurrent processes, support the process of creating, suspend, terminate, recovery, returned to operation, support form, visualization module designer, adjustable graphic element position. According to the characteristics of the life cycle of product research and development, the workflow management system supporting application driven execution. Related applications include document, material, form, submit, archiving, publishing and other life cycle operation, and change, and the implementation of external plug-in program and other program operation. In order to better and faster to process the related personnel, the workflow management system is also integrated message function, comprises a short message sending, mail delivery and IM chat software information system.The workflow management system which is developed by the project, with support for multiple databases, simple operation, integrated application program interface, good man-machine interface, on the whole, can satisfy the product development life cycle management requirements.
