An optimization model of distribution transport using integer linear programming

This article presents a model of distribution transport using linear programming. The overall distribution process is considered to be divided into successive levels between the company and its clients. Origin-destination units are distinguished at each level between an origin and various destinations, with direct transport and with windows in the delivery dates of the orders to be transported. The distribution programming is carried out in each unit through integer linear programming considering in the formulation both limited and unlimited fleets of vehicles. The overall programming is obtained as a superposition of the programming of all the origin-destination units. Validation of the model was carried out using data obtained from a textile company having the required characteristics. It is concluded that the model presented is useful in modeling the companies described, and has permitted the design and implementation of an exact procedure for programming product distribution by the company.
