Research Of Product Configuration Designing Based On Knowledge Reuse

Base on the features of production pattern and product organization pattern of masscustomization, the subject analyses the research development and status of correlative productconfiguration. Depending on logical relation and extended AND/OR Tree structure of semanticnetwork, the subject analyzes its structure, feature and correlation among parts of configurable product,puts forward the structure model of configurable product. Moreover, aimed at the structure, content isincluded and constraint relationship of configurable nodes, the node model of configurable product isadvanced, which contains the general structure of the nodes. The subject sets up the model based onexplicit formulation and implicit formulation separately, depicts the pattern of explicit formulation andimplicit formulation, and puts forward the storage mode and structure model of designing knowledgerule bank and case database. The database model of product based on knowledge reuse is advanced. Inaddition, it puts forward new expression style about blend reasoning, solves the problems of dataredundancy and low retrieve efficiency, which is only based on formula and case expression.The structure model of configurable product based on semantic network is created. Depending onlogical relation of semantic network and the structure, feature and correlation among parts ofconfigurable product, structure model of configurable product based on semantic network andconfigurable node model are set up. The structure model of configurable product involves levels ofstructure layer, module types, power management and constraint relationship between them.Configurable node model is set up from the point of the constraint relationship between configurablemodule, which is the integration of node structure, contained data and exterior and interior interface.Data object model of reusable configuration product is built, in which the object link containsfive aspects:(1) object link of configuration (2) object link of construction (3) object link ofdocument (4) object link of engineering drawing (5) object link of module data. The model canexpress storage data in the product configurator with the object link above.The configuration solving model based on blend reasoning is built, the process of which isdifferent from general process, that is, it is based on the reuse of the past configuration knowledgeafter the appearance of congener product, its progress is a kind of bidirectional configuration process,first from the bottom up and then from the top down. Knowledge rule bank and case database are notonly separately independent but also comprehensive used.The configuration system is achieved. The system is based on the structure model of configurableproduct and data object model of designing knowledge reuse, The functional module in the systemcontains four subsystems: foundational data management of product, configuration management ofproduct, structure management of product and configuration management and so on. Consequently,corporation manufacture can respond to market demands quickly and corporation can produce theproducts that can satisfy the individuating demands of customers.
