highlighted is the set of advantages offered to the participants of the collaborative chain: in order to achieve alterations in the shipping and delivery dates to its clients, it shall achieve gains with the reduction of freight resulting from the joining of loads; which means, the costs of the collaboration shall be lower than the individual actuation costs. Therefore, the proposed model shall comprise a systematic of distribution of these gains in order to make attractive the participation of the entrepreneurs.5.1 Model considerationsDue to the complexity inherent to the factors involved in the performance stages of the maritime transportation, it is required to adopt some considerations for the modeling of the problem:a) Land transportation of large load volumes, allocated in 20 feet containers, supporting a maximum of 24 tons.b) Exporter companies can use the containers individually or in collaboration with other companies; therefore, the load can be closed or not.c) Maritime transportation of large volumes in containers. Ships are not allowed to navigated empty.d) Random transportation demand.e) Dynamic actuation of the containers with the possibility of their storage in ports of the route used between the origin and destination of the load.f) Dynamic actuation of the ships, altering its navigation routes or not, passing or not through pre-established ports.5.2 Model descriptionThe search for a feasible solution for the transportation problem shall also comprise the resolution of the vehicle routing problem, regarding trucks or ships. It can be established a description of the model initially through the overview of the process presented below in six stages:a) The companies, in an independent and dissociated manner, executing its respective business plans comprise the sale of its manufactured products. From this plan the logistics planning areas shall create a storage and transportation plan. In this stage, the proposed model interacts with the individual plans creating a collaborative transportation planning, initially until the source port, considering shipping and delivery dates in the destination, as well the definition of the volumes. The collaborative transportation is initiated in this stage.b) To perform the truck routing between the collaborative companies until the source port.c) Verify the possibility of prompt shipping in the ship or waiting in the port apron. d) The ship verifies if there is load for shipping or landing in the ports of its route and chooses to berth in it or not.e) After shipping, the container can follow in the same ship directly to the destination port or choose for the landing in some port of the route to achieve better arrival date in the destination or better cost, considering the possibility of advance or prorogation in the delivery of the goods. The collaboration in this stage reaches not only the operational planning levels, but also the areas directly linked to the business. The Sales departments of the exporter companies shall agree in advancing or delaying deliveries to its clients, opting for making more flexible or not the time windows. f) The sequence of the model shall close the mechanism proposing an enhanced feasible set of the conjugated routes. The transportation programming shall be the performance of
