Propuesta de optimización de transporte multimodal de piedra picada desde el es-tado Bolívar hasta los campos de la Faja Petrolífera del Orinoco en Venezuela

With the propose of perform a proposal of optimization about  a multimodal transportation of crushed stone from Bolívar state toward Orinoco Oil Belt fields in Venezuela, it was used the operational research technique named linear programming in order to make three mathematical models that could make possible to optimize, by cost minimization, the transportation of crushed stone combining road and fluvial transportation; the proposal was implemented making use of the tool named Solver® of Microsoft® Excel® for resolution of a supposed case due to it is not exist a crushed stone multimodal transportation system right now; obtained results from the implemented case allowed to conclude the suitability of the optimization proposal.
