| Popis: | This paper aims at inspiring a change in the traditional approach of sales and operations planning (S&OP) of integrated steel industries that have reached a maturity planning level allowing the use of sophisticated technologies. Therefore, we propose a two-stage stochastic programming model suitable for reproducing the rolling horizon framework of tactical planning. Simulations of one year of operations in an integrated steel industry showed a potential improvement of about 15% on overall supply chain profit in comparison with a plan produced traditionally. Besides, we evaluated two scenarios to analyze the effects of a flexible plan when facing a tax raise and a capacity reduction. As a practical implication, the model provides a consensus view of the S&OP stages at once, supporting top managers to make better decisions. The two-stage modeling approach also reinforces the need for interaction of the sales team with procurement, production, and distribution teams. |
