The Suez Canal is a strategic route for world trade, and its revenue is one of the key resources for the Egyptian economy, hence the importance of improving the forecasting of its revenues. This research paper aims to model the Suez canal revenues using the optimal method of combining with a view to overcoming the inefficiencies of individual models, and to develop the forecasting models using the fundamental change that occurs to the future values of the time series, as it has come to be known that these models do not take into account the expected increase in Suez canal revenues after the construction of the new canal running parallel to the old one.
