Research And Implementation On Key Technologies Of The Product Inspection Management System

Along with the in-depth application of enterprise information systems, it is necessary for contemporary manufacturing enterprises to bring the product inspection into the information system to achieve better management and control of product quality. The purpose of establishing the Product Inspection Management System (PIMS) is to carry on the electronic management of inspection process and data, and to provide the important quality data for information systems such as ERP and PDM, thus to achieve integration and information sharing between the enterprise information systems.Firstly, according to the results of investigation, the feature and the functions of the product inspection management system were summarized after analyzing the company's demands. The architecture of PIMS was put forward and established.According to the requirements of realizing the electronic management of inspection process, the PIMS based on the product inspection lifecycle was established and the lifecycle was divided into several inspection states. The feature and workflow of process inspection and storage/acceptance inspection were explained and the electronic process was realized through the process definition and message mechanism. The elements and principles of access control were researched. An access control model based on object status and roles was introduced, by combining the feature of the system and the strict requirements of secure management. The basic steps and realizing approach of this access control model was thoroughly explained.According to the requirements of carrying on the electronic management of inspection data, after the analysis of the type and composition of inspection data, the BOM-based inspection data management approach was put forward due to the important role of BOM in the enterprise. The specific organization and management of product certificate based on product structure was explained. The integration with other information systems such as ERP and PDM was discussed.On the basis of the theories discussed above, the product inspection management system is developed. The system has been used in a military company and received a good effect. Some examples of functional operation are illustrated.Finally, a conclusion is drawn and further research is pointed out.
