Design And Implementation Of The Order Of Coal Mine Enterprises Approval System Based On NC Platform

With the development of the times,coal enterprises for their own management and business requirements can be improved,coal enterprises in the order approval process management issues become increasingly prominent.However,the traditional coal enterprise order system in the implementation process generally encounter such a problem,when the enterprise business process changes,the enterprise to achieve the document approval process will become no longer meet the system operating requirements,often need to re-design and implementation.Coal enterprises operating costs are relatively high,so it will be more to increase the operating costs of enterprises,but also because the system can not quickly respond to changes in business processes leaving the operation of the enterprise slow.In the coal enterprises in a large number of coal sales,coal stocks,coal transport and other orders need to fill,approval and settlement of a large number of system reports,system documents and project contracts,how to better achieve more efficient application logic and process logic to separate,It has a very important role in improving the flexibility and maintainability of coal enterprise system.Therefore,the study of workflow development through workflow is very important.This thesis begins with the analysis of the requirements of the order audit process system and prospect of order approval system,then according to the workflow technology research,introduces the related technology of workflow and workflow engine,comparing several kinds of workflow engine.Based on the analysis and comparison of the main workflow engine,aiming at the problems in the application.Then,by the secondary development of UF NC platform to achieve the approval process as mainline,with the analysis of the system function,describes the application of the system architecture and workflow engine in the system and the specific implementation details,the realization process of the approval process,transaction control and other functions.In order to solve the special requirements,we use the workflow engine to realize the dynamic change of process and organization model in the actual business,complicated process,sign and other key issues,which realized the appropriate flexibility order of approval system.It provides a good reference for the design and implementation of similar systems...
