Using Simulation to Improve Profitability and Supply Reliability of Tata Steel UK Integrated Supply Chain

Using Simulation to Improve Profitability and Supply Reliability of Tata Steel UK Integrated Supply Chain

Development of dynamic supply chain simulation model for Tata Steel UK (2 plants, 28 production centers including 3 casters, 49 external warehouses). The model embraces production scheduling, WIP and finished products inventory management as well as transportation by rail and sea. The model is used to identify system bottlenecks for different demand profiles. Another purpose of the model is to develop, test and evaluate algorithms of prioritizing production and customer orders.
