The proposes of this paper are to investigate the properties and methods of fuzzy time series. It starts off with introducing the fuzzy time series analysis proposed by Q. Song and B.S. Chissom. Then, the theory structure, calculation, forecasting procedure and application of fuzzy time series are characterized from a comparison between traditional time series and fuzzy time series.
In this paper, the generalized asymptotic synchronization between Chen hyperchaotic system and Liu hyperchaotic system is investigated. The two hyperchaotic systems to be synchronized are represented by the T-S fuzzy models with a small number of fuzzy IF-THEN rules exactly. Then, based on the T-S fuzzy hyperchaotic systems, a simple fuzzy controllers is designed via parallel distributed compensation...
In this paper, the FAHP method is adopted to assess the supplier and each alternative design scheme separately with evaluation class and performance indicator. The integrated performance indicator of each design scheme is obtained by aggregating evaluation class of its supplier and its performance indicator is used to be the criteria for measurement and selection. An illustrative example with the...
