The present work was based on a project called ALOGTRANS developed by Industrial Engineering Department of Catholic University of Rio de Janeiro (PUC-Rio) jointly with six institutions. The purpose of such research is to propose alternatives to mitigate and/or eliminate the main logistical bottlenecks from harvest flow in order to reduce logistical operation cost, mainly by the use of multimodal transport. In such project, we analyse the production flow of soybean, soybean meal, corn and sugar from Brazilian Midwest, using multimodal-multiproduct allocation means through ALOK software (developed by Industrial Engineering Department of PUC-Rio). In this sense, the main objective of this work is to update transportation cost related data used as input to ALOK. Furthermore, we succinctly describe the present market of Brazilian commodities and also the main flow routes.
