Taiwan Futures Exchange (TAIFEX) is the world's 23rd futures exchange to trade SSFs, which is also the 21st financial product offered by the exchange. In this paper, the TAIFEX is predicted based on improving fuzzy time series model. Nature-ratio lengths of intervals technique is employed to partition the universal of discourse of linguistic variable and an improving high-order heuristic function...
Because there exists drawback in traditional type-1 fuzzy sets to deal with uncertainty, type-2 fuzzy sets have been proposed to replace their type-1 counterparts. This paper presents numerical calculation procedure of computing with words for interval type-2 fuzzy set (IT2 FS) based on fuzzy extension principle. Three kinds of interval type-2 fuzzy sets, such as discrete, semi-discrete and continuous,...
In this paper, we propose a new method for enrollments prediction, based on fuzzy time series. The new method constructs high-order fuzzy logical relationships with high-order heuristic function based on the historical data and uses nature-ratio techniques to partition the length of each interval in the universe of discourse for enrollments forecasting to increase the prediction accuracy rate. The...
According to the evaluation problem of enterprise core competence, this paper proposes a new size comparison method of the triangular fuzzy number and establishes an evaluation model with the combination of the entropy and triangular fuzzy number. Then, it provides a new evaluation method with the combination of qualitative and quantitative researches. The empirical studies has shown that the evaluation...
Due to the complexity of traffic flow characteristics, the traditional statistical regression models have been unsuitable for the traffic flow prediction. And thereby the paper proposes the fuzzy time series method to predict short- term traffic flow. First, we proposes an improved fuzzy time series prediction model, i.e. , ratio-median lengths of intervals two-factors high-order fuzzy time series...
Customer relationship management is one of the leading business strategies for today's companies, the key to successful implementation of CRM is customer intelligence. This paper designs and implements a customer intelligence system based on improving LTV model and data mining. Two data mining techniques are used including self-organizing map and fuzzy decision tree. The proposed system provides such...
In this paper, based on the foundation of the discussion of Sugeno integral for real functions which was presented by Wu Congxin and Mamadou in 2003, we introduce and consider the concept of the absolute additivity of Sugeno integral for real functions, we also discuss the ordinary additivity and fuzzy additivity of Sugeno integral for real functions. For these three kinds of additivity, we obtain...
