Research On Theory And Method Of Product Family Model For Customers

The mass customization (MC) mode has become the main production mode in the 21st century due to the change in the demand of product market and the product family model (PFM) is the key technique for implementing the product design of mass customization mode.By analyzing the current related research situation at home and abroad and the actual need of the enterprises, the limitations of the current research work are as follows: â‘ In the PFM research, the PFM can not completely satisfy the customization requirement of the customers. The research on the expression theory, method and implementation technique of the models is not adequate in the function and structure models of PF. The implementation of the PFM did not use the concept and tool of the database management. â‘¡In the cost estimation of the product configuration instance, the cost estimation of the commonly used deformed parts did not make a full use of the similarity features in the structures, materials and techniques of the parts family. The estimation method is multi-factored, complicated, low-efficient and unsteady in accuracy. â‘¢In the evaluation of the product configuration instance, it is impractical to correctly understand the customers' requirements and configure the only product instance. The evaluation for the product design project which has less evaluation information can not substitute the one for the design project which has rich evaluation information. The method which takes the manufacturer as the principal part of the evaluation is widely divergent from the one which takes the customers as the principal part. â‘£In the management of the design knowledge of PFM, due to the restriction in the relationship between the product and its process knowledge which is heterogeneous and complicated in the semantic connotations, the object-oriented knowledge expression model did not supply the rule which apparently defies the semantic connotations and the relationship for the knowledge objects, thus causing difficulty to understand and share the knowledge.Aiming at the above limitations, this thesis, by employing the set theory, the hypergraph theory and the analytical hierarchy process, will research and solve the key technical problem of the organizational structure, expression and implementation of PFM in order to do some new research on the PFM at a higher layer which is different from the former works on the product customization and to achieve the goal to fully comprehend the structure of PFM and to make a full use of the enterprise resources to satisfy the customization demand of customers.On the basis of an analysis on the operation flow of the MC mode, the customer-oriented MC mode operation flow is proposed. According to the MC philosophy and method system, the requirement analysis of PFM is done. Based on the result of the proposed operation flow and requirement analysis, the PFM which is composed of the data layer, logic layer and the...
