Usually, the lifetimes and repair times of series systems are assumed to be random variables. The probability distributions of the random variables have crisp parameters. In many practical situations, the parameters are difficult to determine due to uncertainties and imprecision of data. So it is appropriate to assume the parameters to be fuzzy variables. In this paper, the lifetimes and repair times of components are assumed to have random fuzzy exponential distributions, then the limiting availability, steady state failure frequency, mean time between failures (MTBF), mean time to repair (MTTR) of the repairable series system are proposed. Finally, a numerical example is presented.

In this dissertation, based on comprehensive analysis of the theory of coordinated development of "Higher Education-Economy" composite system (HEEcS) at home and abroad, established complex system models of two aspects-higher education and the economy. By using the methods of synergetic and efficacy coefficient and so on constructed the efficiency function and the coordination of function of Heilongjiang province HEEcS, and established the evaluation of coordination degree index system to evaluate the coordinated development of the level of Heilongjiang HEEcS. The results show that the orderly degree of Heilongjiang HEEcS is continues to rise, systematic coordination is steady growth, but the system's overall coordination is in the lower level, to that point the fundamental reason is the low level of economic development. The two aspects only in the long-term state of sound development can improve the coordinated development of HEEcS.

Since SVM is unfair to the rare class for the classification of unbalanced data, a new balancing strategy based on common strategy of undersampling the training data is presented. Firstly, the fuzzy C-means clustering algorithm is used to cluster the unbalanced data sets, and choose the negative class samples whose memberships are greater than a certain threshold (supposing the number of positive class samples is less than that of negative class samples). The selected samples and the positive class of original samples are combined into a new training data set. After that, the new data set are used to train a support vector machine. At last, the simulations on unbalanced data show that the proposed algorithm can compensate the ill-effect of tendency when support vector machine are utilized to deal with the unbalanced data classification. Moreover, compared with the traditional support vector machine and some other improved algorithm, the proposed algorithm performs superior classification ability.

To overcome the limitation of hand shape recognition, the paper presented a recognition method of hand shape fusion based on the fuzzy neural network of BP. By means of fuzzy neural network of BP, the method analyzed the fusion computing for the collected hand gesture and lip shape image, viewed respectively the fusion image as the fuzzy set of hand gesture and lip shape, made the operation of fuzzy arithmetic operators for fuzzy set, matched the operation results and the sign of hand gesture and lip shape in database, carried on the fuzzy set operation for the gotten two sets of hand gesture and lip shape, finally got the recognition result. The simulation experiments show that the presented method is better in sign Language recognition, and it maybe has wide realistic application foreground in the education of deaf-and-dumb people.

In the fiercer market competition,the hospitality's core competition determines the enterprises' survival. It is also the key to overcome rivals and obtain sustainable development. The paper uses the theory of fuzzy comprehensive evaluation to construct the system of core competition index assessment. Then from the angles of quantitative analysis and qualitative analysis, it makes a comprehensive evaluation on the hospitality's core competition, which provides the theoretical basis for the effective management strategies and promotes its sustainable development power.
