| Design Change refers to the adjustment of the original design document by the design unit according to the needs of customers,projects or when the revision finds errors.It is a very common and important work in the scientific research,production and business activities of manufacturing enterprises.With the continuous development of enterprises,the continuous application of digital manufacturing and other technologies,the frequency of product innovation and improvement is getting higher and higher.At the same time,the popularity of customization and agile manufacturing makes the traditional paper management mode increasingly unable to keep up with the pace of change,which makes the company waste a lot of manpower and material resources in the management and design change.Many enterprises have established on the basis of PDM and ERP and MES system advanced digital management system,but inevitably some foreign civil aircraft subcontract production parts still use paper drawings to change,want to spend a lot of energy to change the implementation of management,at the same time,the lifecycle of change,execution can’t timely tracking,process is not transparent,not dominant,is not standard,there are in process and the possibility of wrong order,cause huge manpower cost and loss of reputation at home and abroad;Paper results are not easy to query statistics,the results of electronic need two manual input,low efficiency and heavy workload.In order to improve the management efficiency,standardize,informationize and make the work flow explicit,and eliminate the process error,we decided to develop the civil aircraft parts design change execution management system on the digital workshop platform.This paper fully refer to the relevant procedure documents,investigation analysis and finishing the business scenario design change implementation,comb,build civil aircraft parts design change management business model,based on the ORACLE database,using Entity Framework framework,B/S architecture technology,independent development and coding related content,including the business logic of each business module,business processes,detailed interface,etc.,construction of civil aircraft parts design change management system.This system for civil aircraft parts design change management effective means will provide fast,accurate and reliable,can realize automatic coding to civil aircraft parts design change according to the rules,according to the different processing results are accurate start corresponding management process,and real-time tracking management process,will be the implementation of civil aircraft parts design change process standardization,standardization,and be innovated,a key assigned task,convenient query statistics,greatly improve the efficiency of management,history data backup permanently preserved at the same time,save paper material and storage and management costs.The test and practice show that this civil aircraft parts design change management system basically meets the company’s requirements in terms of stability,practicability and interface design.At the same time,the system has strong usability and expansibility,and can be quickly adapted according to the changes of management process and mode,and the design goal has been reached... |
