[Abstract]:At present, the research of management and decision making method based on data driven, is a hot issue in the field of management science research. Because of the complexity of the decision environment and decision-making behavior, in the context of large data according to user preferences and knowledge discovery, realize personalized recommendation to users, and how to use the multi attribute decision making method and personalized recommendation system by combining the research of personalized recommendation system based on multi-attribute decision theory has important theoretical value and practical significance. This paper will mainly use the type two fuzzy sets the powerful processing ability of language and semantic information, to type two fuzzy information integration and decision method as the starting point, combined with the relevant methods of granular computing and technology study of type two fuzzy decision making method based on Personalized Recommendation Model for large data under the background of complex, dynamic, personalized recommendation problem with incomplete information The research provides new ideas and solutions. The main contents of this thesis are as follows: (1) based on the theory of information integration, puts forward the interval Maclaurin symmetric mean type two fuzzy operator based on information integration, and gives its dual form and index extended form were studied. The parameters of the single tone, and points out that compared with the existing range of two fuzzy information aggregation operator, interval type two fuzzy Maclaurin symmetric mean operator can flexibly deal with the multiple correlation interval type two fuzzy information integration problems. On this basis, put forward a method of processing interval type two fuzzy decision problems, and its application in China sciencepaper online paper review recommendation system. Provide a new method of type two fuzzy decision problem as the research has a relationship. (2) based on multi-attribute decision-making theory, respectively from the sorting method, the utility model and optimization Three aspects of research model of multi attribute decision making method based on interval type two fuzzy information. Firstly, according to the type two fuzzy sets is a difficult problem: scheduling problem. A value of three methods of combination of elementary average sorting based on given. And from the angle of mathematics proves that the method can not only satisfy the linear order sequence (total order), but also meet the admissiable relation. On this basis, further research on the fuzzy decision making method based on interval value ranking combination type two. Then, the behavioral decision theory based on reference number of flexible three parameters in Behavioral Economics (FTP) utility function, gives the fuzzy OWA operator based on FTP utility function type two, and for large and complex decision problem, we propose a fuzzy multi attribute decision making method based on fuzzy clustering interval two. Further VIKOR method combining with classic prospect theory, was researched. From the dynamic point of reference interval type two fuzzy behavior decision method, and its application in the high-tech investment risk assessment recommendation system. Finally, the LINMAP in multi-objective optimization (multidimensional linear programming) method is extended to the interval type two fuzzy environment, extraction method studied the preference of decision makers, established a a series of incomplete information on attribute weights and the optimal decision-making model and its application in personalized recommendation to buy mobile phone. The new method, further enrich the theoretical system of type two fuzzy decision making method, but also extends the type two fuzzy decision theory in the application scope of processing personalized business recommended (3). Based on Granular Computing Theory and sparsity problem of personalized recommendation in the score matrix. Based on granular computing method as the starting point, based on the Coverage and Specificity standards as the core of the collaborative optimization model. The intelligent optimization algorithm to solve the model. In a certain extent overcome the high computational complexity of matrix decomposition and variational optimization method based on the existing brought, provide a new research means and methods for solving the bottleneck problem in personalized recommendation. (4) type two fuzzy decision making method based on personalized recommendation model. Two kinds of multi attribute decision making method of new BTW and MULTIMOORA as the foundation, combined with the optimal particle information modeling method, put forward the recommendation model for hybrid multiple attribute collaborative filtering and content-based recommendation model. The parameters for the solution of the problem of setting, personalized, parameter setting method has been applied to differentiation. The method mentioned in this paper are type two fuzzy multiple attribute decision making problems. The relevant research results in theory can further enrich and improve the type two fuzzy information based on decision theory. On the application level, it can provide new tools and methods for the personalized recommendation of e-commerce.
