Workflow Technology And Procurement Management System Applied Research

Workflow is a type of technology which is used in operation modeling and realizating business processes re-engineering in the business calculation. The content of workflow is a serial of connection with each part, taking action of operation activity or mission automatically. Workflow manage system is a system that is designed to define, initiate, manage and optimize workflow by software. The goal of workflow is to make generous assignments and activities to coordinate well with one another and to send the correct information to the right person at exact time, which make sure to accomplish the correct operation flow. The application of workflow manage system can accelerate the internal business and management flow, rise the efficiency of dealing and realizing dispose automation or semiautomation.Basic concept and research status quo of workflow has been first introduced in this paper, the author has provided the workflow reference model defined by Workflow Management Coalition, and has designed a workflow management system based on J2EE(Java 2 Platform Enterprise Edition) and Web technologies according to the reference model and analysis of real business requirements by using object oriented method. A solution based on J2EE platform has been raised according to the reference model of workflow management system, aiming directly at the shortage of distributed workflow control system, such as the awkwardness in the aspect of workflow definition and the difficulty of the complex workflow definition and so on. Some key parts have been discussed, containing workflow model, workflow engine, workflow interface, and its functiona form. Focusing on the workflow model and the workflow engine, the author has made a detail research, has designed his own workflow model based on the former ones, has developed a EJB component-based lightweight workflow engine, and has introduced the structure and logic of the engine in detail note.A practical process of procurement has been used as an example to test the workflow management system which has been redesigned and has been developed according to this paper. The desertation has impled the coordination and sharing of information and data of manufacturing enterprises' purchasing sector, and has promoted standardization, platform and automation of the purchasing management system. The purpose of this study is to provide a reference solution for modern manufacuring enterprises to achieve Business Process Reengineering, and enhance its operational efficiency.
