The Petri net models of the production procedures are built and simulated in order to calculate specific performance measures. Then exponential smoothing method is applied in order to forecast the overall demand of the upcoming year for each product type. Finally, a scenario concerning partial change of the equipment efficiency is tested and the results obtained are compared to the ones of the initial model.http://creativecommons.org/licenses/by/4.0/1284-128924th Mediterranean Conference on Control and Automation24th Mediterranean Conference on Control and Automation Vrontakis Konstantinos Βροντακης Κωνσταντινος Kabianakis Andreas Καμπιανακης Ανδρεας Tsinarakis Georgios Τσιναρακης Γεωργιος Institute of Electrical and Electronics Engineers Production Industries Petri nets Smoothing methods Predictive models Raw materials Process control
