| This dissertation presents a theory and method of demand feedback and navigation based on dynamic DSM as well as method of cost estimation for product components based on virtual configuration, after studying and analyzing the characteristics of customerized requirement, in order to obtain customer individual reqirement more quickly and more correctly, reducing the non-standard rate of customer demand, providing a good foundation for the following quick response to customer's requirement. On the basis of the theoretical research, a system of requirements elicitation and rapid cost estimation is developed.The dissertation is organized as follows:In the first chapter, the dissertation analyzes the characteristics of customerized requirement, and reviews the history and present status of some key technology of quick response to customer's demands. In view of the shortcome of response to customer's demand, it presents technology of demand feedback and navigation based on dynamic DSM to reduce the non-standard rate of customer demand, building a solid foundation for the following design, manufacturing and other process.Based on this, virtual configuration help carry out estimating cost quickly and accurately, in order to give a quick response to customer's inquiry.In the second chapter, the dissertation presents the actualization and application of demand feedback and navigation method in detail. First, static potential contradiction DSM is created based on coupling rules of product design parameters. Then, the DSM is transformed according to the priority order of product properties, in order to totally plan the customization system. Finally, the DSM is dynamically transformed according to specific demand, providing overall process feedback and navigation for customers and helping them complete customization demand. As a result, this technology was applied in the customization system of elevator product, and non-standard rate was decreased remarkably, and also the efficiency of customer demand response was improved.In the third chapter, the dissertation presents technology of customerized product virtual configuration. It mainly introduces to technology modeling and process template of VS, as well as the method of instancing the VS according to customer demand during virtual configuration. Meanwhile, it studies and explores the configuration related technology. Finally, it describes the theory and realization process of customerized virtual configuration.In the fourth chapter, the dissertation presents method of cost estimation for product components based on virtual configuration, after comparing and analyzing the traditional method of cost estimation and quotation. The key of cost estimation for product components was the cost estimation of VS. It presents the concept of process template and the mechanism of process-generating during virtual configuration. The cost of VS is calculated according to new-driven process cards, and then, the cost of product is calculated by the configuration BOM from VC. As a result, reliable basis for product quotation is provided by calculating the total cost of product components.In the fifth chapter, the theory and method discussed above are applied in elevator industry. The system of feedback requirements elicitation and quick cost estimation has been developed and its main functions and the realized techniques are described and presented. The application and implement result of this system have proved that the theories and the methods have good practical value.In sixth chapter, all achievements of the dissertation are summarized so as to put forward the further research. |
