Abstract: Production planning and sequencing in hot strip mill (HSM) process consists of decision making about three important issues: assigning the orders to slabs, building up programs from the slabs, and sequencing the programs on rolling machines. In contrast to earlier investigations that mostly focus on one of these issues, a comprehensive mathematical model where considerations for both mid and short term planning horizons are simultaneously taken into account is presented to formulate the whole problem. A greedy algorithm is then presented to solve the model in a reasonable amount of time and used for planning in Mobarakeh Steel Company (MSC), the biggest steel enterprise in the Middle East. Computational experiments demonstrate that the proposed method substantially increases the productivity in MSC by decreasing the total tardiness of orders, unsupplied demands of products, setup times and optimally utilising the lifespans of rollers.
