Configuration Design On The Extension Logic For Product Family

Along with the globalization market formation and the technical changing acceleration, the traditional relatively stable market environment develops gradually to the dynamic changeable direction. The huge challenge is how to satisfy the costomizated demand at the low cost, high grade and the quick product date of delivery. This dissertation is under the National Science Foundation (50575207) and the National 863 High Technology Program Foundation (2002AA411110).Design for the product family is the inevitable result because of the market perturbation, the customer demand and the diversification, diverse, the personalized product, which share the small enterprises to provide more opportunities, but simultaneously also bring the enterprise and the product development more challenges. So how to deal with the contradiction problems by the artifical intelligence has become very important.This dissertation took the extension logic method into the product configuration design process. The main contributions of this dissertation were as following.After the existing research and the dilemmas in the product configuration design were summarized. Then six main methods design for framework, design for model, design for reasoning, design for common module, design for varieties, design for assembly and design for mass customization. Then the extension design flowchart was introduced. Finally present the main content of this paper.Firstly, to build the qualitative and quantitative extension model, the conflictions in the different steps for configuration design were analyzed. A net or tree model were built to stand for the configuration process at the support of relationship matter element extension. Another confliction resolution cycle model was presented to realize the case modifying. As a result, the basic framework to deal with the extension knowledge was advanced.Secondly, to solve the complex relationships between different parts, the division in the configuration database on extension cluster was realized. Its focus was to make sure the relationship in the different parts. Through the relationship standard, a new product structure division method which satisfies the individual and correlative need was presented. After the transforming on the common model, the database is more suitable for retrieval.Thirdly, at the purpose of the similar parts retrieval, a configuration method on extension relationship-matter reasoning was presented. Its focus was the similar structures in the same design space which were hard to retrieval. After the demand and structure mapping, the similar structures for configuration are generated. Then the general retrieval method was employed to finish the configuration process to satisfy the different customers' demands.Forthly, one method to deal with the case transforming on Extension mining was advanced. Its aim was to realize the transforming process's auto-generation. According relationship-matter model, the general configuration rule could be changed into an extension rule. On the confliction transforming, the conflicts between different product structures could be mined. Then the relationships between transforming effect and the configuration ability could be built. Finally a transforming case could be generated.Finally, the prototype system for extension product family configuration, to the various design spaces was realized, global conflicts and changing demands, using the extension cluster method, demand and structures mapping, extension reasoning method and extension transforming method, the system solve the conflicts in the configuration process.
