Simulation and Optimization of the Power Station Coal-Fired Logistics System Based on Witness Simulation Software

Based on analyzing characteristics and relations of the power station coal-fired logistics system, including the choice of coal suppliers, the railroad transport system, the power station stockpile system, the power station coal transfer system and human resources, by Witness software the thesis sets up a simulation and optimization model of fuel coal logistics system and analyzes one example in detail. The model results not only macroscopically image bottleneck points and resources availability, but define optima separate stage ordering goods batches and stockpile quantities. The thesis is powerful and significant for thermal power station to establish scientific reasonable logistics system strategies, reduce the cost and increase competition ability.
