Automobile New Product Oriented Extended House Of Quality Research

With the advent of the 21 st century,automobile industry is developing very fast in our country,people's material demand levels are increasing,cars are more and more important for people,This market environment brought development opportunities to auto makers,but the demand of the market is always changing,it puts forward new challenges to the auto makers.In the face of the various personalized needs of the market,car manufacturing companies began to take the customer as the center,and the research and development of this enterprise car response to the changing market of new products.However,from the Angle of system,automobile products belong to the complex system,mainly embodies the auto industry there are many different kinds of complex manufacturing process,parts,and the fast changing market demand,etc.,The characteristics of automobile products,makes automobile new product development often put huge manpower and material resources,financial resources,But at the moment the car on the market of new product feedback,to achieve their goal of new product on market is not much,it not only bring huge losses,but also cause the waste of resources of our society.Therefore,to improve the quality of automobile new product,make the car can sit tight market,truly a share in the market,is the problem that each car makers to consider.In this situation,the automobile production enterprises need to grasp the quality of the new product entering the market,so as to realize the continuous improvement of the new research and development model,and improve the quality and performance of the car.In the face of the current situation of automobile new product face,in order to meet the demand of the market and the demand of the enterprise,after a reference of other literature,this paper put forward effective for automobile new product improvement method.First of all,the paper takes the 4S database and RFID database as the starting point,and uses statistical tools to analyze the sales data of the new automobile products.identify the product of the problem.Then,according to the related problems to establish the relevant database,and combined with the rough set data mining technology to extract the feature of the problem,the feature is that the user's needs,will constitute the quality of the left wall of the house.Then,according to the complexity of the automotive product system and the shortcomings of the traditional quality housing,the application of the model in the product development is improved,build the extended quality house model,promoted the crossover study of discipline,improved the quality of the original house shortcomings.Finally,this paper takes a certain vehicle as an example,collects the 4S store sales data and RFID database information,and applies the rough set data mining technology and the extended quality housing model to analyze and deal with the guidance of the new productimprovement.
