This work aims to solve a problem where several tactical issues related to a company supply chain are considered: supplier selection, raw material purchase, inventory management and sale optimization. For a more realistic representation, the model also takes into account the demand and provision uncertainty in the decision process. A multi-objective disjunctive optimization model is proposed where discrete decisions are represented using Boolean variables.
