Abstract: This research investigates the production planning challenges in steel production. The strategy for steel manufacturing by the case company has changed in response to the pressure of the global markets. The original strategy resulted mostly in a push type of production planning that took the customer's orders into account at a certain point in the production line. Currently, the company is driven by customer's demand, which has resulted in more dynamics and larger variations in the production runs. The theory is built upon operations management, with a focus on production planning. The results indicate that the special nature of the production planning environment, which includes multiple variable process components in steel manufacturing, therefore contributes to the challenges in achieving a balanced production flow. The study evaluates the reasons for production scheduling challenges and examines the overall flow of steel production from an operation's optimisation point of view. This study brings forward the new data on measurement done in one critical production phase of steel production, thus giving example on variation at the single-process phase yielding to total variation of the system.
