Research And Implemention Of Technology Of Forcastingtechnology Maturity Based On Patentanalysis

the technology maturity help companies to find their weakness, improve their skills targeted, develop a scientific strategy for product development and technological innovation, and search for innovation. Maturity of the product is the the first important indicator to be considered for enterprise which intent to make development strategies of product development and technological innovation.this also is the reference scale of technical trade, or some of the functions for some partment to research and development project. Therefore, maturity of product technology forecasting research is definitely necessary.The existing technology maturity mapping model has some problem in the accuracy of the results and the actual operational aspects. We make a comprehensive analysis of the TRIZ theory and foreign and domestic methods of echnology maturity mapping. Aiming to resolve the existing inadequacies of the current methods, through researching user needs, based on the relationship between technology life cycle and user needs we proposed a model of technology maturity mapping.we analysised and demonstrated the importance of user needs and researched their relationship with the technology life cycle based on the the hierarchy of needs and QFD theory.Based on researching the role of needs in technology development,we analysis and appraisal the product function and the relationship to the technology life cycle; Applicated of QFD theory evaluated the quality of function of porduct. Patent records the history of the product technology development, we definited the function improved by this patnet as the function of the patent.Based on the function of patent we proposed the.technology maturity prediction model, the model use the number of patents, patent level, functional level of patents and the relationship between patent function evaluation and the expected evaluation of the level of maturity as four indicators for the prediction. By judging the average level and quality of function of all the technology-related patents in the past three years, then applications technology maturity prediction model to predict the maturity of the technology.Finally, using the Visual C# development environment, we realized the technical maturity prediction system that implements the above forecasting model for technology maturity mapping. We have implemented Curve fitting using the support vector machine theory. And we use this system mapping the technology maturity of the refrigerators, experiments show that have taken a good effect in the aspect of the feasibility, objectivity, accuracy….
