Quality Management For Airliner Collaborative Design And Manufacturing

Aircraft industry, one of the most important high-technology strategy industries inour county, is recognized as the country’s comprehensive national strength, andrepresents a country’s overall industrial level. As an important part of aircraft industry,the development of civil aircraft plays a decisive role in promoting the status of ouraircraft industry in the national economy and international influence, and aircraft qualityis the most important factor in the success of civil aircraft industry. In order to ensure theaircraft product quality, it is necessary to study the quality management of civil aircraft.Quality management has not formed a complete system yet, and lack of practicalexperience in civil aircraft industry in China.The existing quality management modelcannot be fully applicable to the civil aircraft manufacturing enterprises. Therefore,researches on collaborative quality management of civil aircraft are of great significance.With the background of the situation, after analysising the quality information’scharacteristics gathering in the aircraft collaborative design and collaborativemanagement needs, this paper puts emphasis on the researches about the theory and keytechnique of quality management of civil aircraft.The main research contents andconclusions are as follows:Firstly, according to the characteristics of civil aircraft collaborative design andmanuacturing, the paper summarizes the collaborative quality management content.Withthe characteristics and demand of large passenger aircraft collaborative qualitymanagement, it proposes a three-dimensional collaborative quality management structure.Based on this, then it builds the quality management function model of aircraftcooperative, and the key technologies of collaborative quality management are presented.Secondly, the information model of collaborative quality management is established.Information model is the basis of quality information management, and completeinformation model brings great convenience for the quality information management.This paper first introduces the product information modeling and its significance and theinformation data of civil aircraft cooperative quality management is also analyzed.According to the requirement of civil aircraft quality information management, weestablished an integrative model of collaborative quality information that based onthe thought of domain thought, meta model and BOM structure.Subsequently, the modelis described in detail. The model integrates all the quality information model ofcooperative quality management domain by using the the expression method ofmeta-model (object, quality attributes, constraints, operation). Through this way, the expression and management of quality information of civil aircraft products are realized.What’s more, collaboration enterprises and other large passenger members involvedduring production activities are able to achieve the sharing of quality information andimprove the production efficiency. Then we study quality-oriented management methodof civil aircraft materials. After analyzing material classification in general discretemanufacturing industry and the existing problems in S company, we points out thedeficiencies in current civil aircraft quality management. Combined the characteristics ofcivil aircraft materials with the classification indicators in general discrete manufacturing,we propose a quality-oriented civil aircraft adapted materials evaluation andclassification system. In order to make the classification method widely used in allaircraft material, SVM is used for optimization of materials classification. Finally，weobtained a satisfactory result. Based on the classification method above, we propose amaterial management system. Different types of materials adopt different managementstrategies to achieve the quality management of the material itself and its information.Collaboration Quality Management of suppliers is also studied in this paper. SupplierQuality management includes vendor selection, performance appraisal and many othercontent, this paper focuses on the evaluation method of suppliers’ comprehensivecapacity. At the same time, we design an acquisition method based on triangular fuzzynumber. And a supplier evaluation model based on AHP and Grey is proposed. Thefeasibility is verifyied with demonstrated examples. This model can providedecision-making support for civil enterprises supplier, and the supplier’s qualitymanagement is of great significance.Finally, according to the needs of the project and real problems，a system ofcollaborative quality management of civil aircraft products is developed by using thetechnology of advanced database and integrating some corresponding function modules.The theory and the developed system mentioned in this paper have received highestimation.The work has the profound significance to improve the level of collaborativequality management of civil aircraft cooperative design and manufacturing.
