Abstract
The research is dedicated in the study to time series and the ability of using fuzzy logic with it in order to develop forecasting approaches. In this research ,the time series (Autoregressive model) are linked with fuzzy logic in order to get on the Parameters of fuzzy time series models (fuzzy logic Autoregressive model),and applied that on the data of daily mistakes rates in charges production. The fuzzy Autoregressive model of time series gave forecasting more sutiable than those given by Autoregressive model.
