Abstract: This study describes the Mixed Integer Linear Programming (MILP) model developed for a Brazilian company CVRD that manages the only active producing unit of potassium chloride in Brazil. The extraction of potassium chloride is characterised by a constant level and a seasonal demand, since it is an agricultural input. In this study, a dynamic multiperiod model was developed for warehousing planning and distribution. The application of this model helped in the decision-making process of establishing new warehousing systems. Possible gains that can be obtained in the negotiation of delivery dates and sales prices are also analysed.
