| Resumo: | In the context of pig farming, this paper deals with the optimization problem of collecting fattened pigs from farms to deliver them the abattoir. Assuming that the pig sector is organised as a competitive supply chain with narrow profit margins, our aim is to put analytics into practice coping at a time with the uncertainty in production costs and sale prices. Motivated by a real-life case, the paper analyses a rich team oriented problem with homogeneous fleet, stochastic demands, and maximum work load. After describing the problem and reviewing the related literature, we introduce the PJs heuristic. Our approach is validated and tested using a series of adapted instances to explore the gap between the solutions it provides and the ones generated by existing approaches. |
