This is mainly due to the presence of variousmodels for forecasting time series, as well as introducing new techniques foranalysis and predictions. In this paper, expert system structure is used toreplace traditional methods of model identifications for time series. Firstly,several search engines are defined and analytical methods are specified. Next,the knowledge base is developed such that a proper model can be assigned toeach data set. The goodness of fit is then evaluated by mathematical indices.Repeating the process and modifying the responses to account for uncertainsituations, will provide a set of models to make the final decision. Lastly,the performance of the proposed expert system is verified by a series of sampledata as a case study and the efficiency of the system is approved.}, keywords = {Expert system,forecasting,time series,Forecasting error}, url = {https://aie.ut.ac.ir/article_51786.html}, eprint = {https://aie.ut.ac.ir/article_51786_8223837521a5d5b4f6a44d3cd78201d9.pdf} }
