Abstract
Today’s smart production facilities’ increasing modularity and continuous reconfiguration require appropriate logistic support processes. The main challenges here are complexity and the frequent alteration of factory output. To cope with them the resulting logistic system is over dimensioned compared to the average, in order to match the change of needs in the production schedule, which frequently leads to inefficiency in energy consumption, as a relatively large logistic system supplies the production. The current paper describes a method where the material flow system is controlled in a way considering both aspects of schedule adherence and energy management. A simulation model has been developed to prove the concept’s applicability. Results have indicated that the proposed control method reacts effectively for the urgent tasks and change of workload.
