Design And Implementation Of The Production Management Information System For A Machinery Factory

The production management information system in a machine factory is a system developed for the machine factory achieve the business process standardization,achieve the management process informatization,achieve the information flow automation,achieve the the resources and knowledge sharing.The system is a typical computer supported cooperative work system,which build in a lightweight workflow engine based on relational database.and through the system,the machine factory realize computerized management of production process.The dissertation mainly discusses how to realize a lightweight work flow engine based on relational database.Then discusses how to base on this engine to realize informatiive management with the specific production business flow of the machinery factory.UML(Uniform Modeling Language)is used as the modeling tool to model the system requirements model and the system logical model.Microsoft SQL SERVER is used as the system's database platform and PowerBuider is used as the development tool.This dissertation mainly discussed from the following aspects:firstly discussing the principle of realizing a lightweight work flow engine based on relational database,expounding this engine's node structure,the primary algorithm of the engine and the engine's entity relational model.The history,main contents and general methods of UML are also introduced.On this basis,the dissertation introduce the general method of requirement modeling using UML,and how to build the use case model of this sytem..Then the dissertation introduces how to build logical model of the system using UML based on the use case model,including system's static view and dynamic view.Then introduce the realization course of this system,and display the main system function interface.Then the dissertation introduces system test process,including test plan,test cases and test result analysis.At lastly summarizes the development course of system,and envisions the direction of further improvement on the system.
