although there are many excellent ways presenting the principle of the classical calculus, the novel presentations probably leads most naturally to the development of the non-newtonian calculus. the important point to note is that the non-newtonian calculus is a self-contained system independent of any other system of calculus. since this self-contained work is intended for a wide audience, inc...

Fuzzy time series have been developed during the last decade to improve the forecast accuracy. Many algorithms have been applied in this approach of forecasting such as high order time invariant fuzzy time series. In this paper, we present a hybrid algorithm to deal with the forecasting problem based on time variant fuzzy time series and particle swarm optimization algorithm, as a highly effici...

Cooperatives need consideration in the making of business strategy decisions. Forecasting can assist cooperatives deciding on their strategy. This study used n-orde Fuzzy Time Series Chen. Chen captures data patterns formed by two or more historical each period called fuzzy logic relation (FLR). The pattern FLR is to be projected forecasting future conditions. 2-orde, 3-orde, and 4-orde with 1-...

In this work, a new approach to cluster large sets of time series is presented. The proposed methodology takes into account the dependency among obtain fuzzy partition set observations. A two-step procedure accomplish First, cophenetic distances, based on linear cross-dependency measure, are obtained. Second, these distances used as an input non-Euclidean relational clustering algorithm. As res...
