individually the freight prices with the shipowners, they do not have bargain power to attain better prices. This is the point where the collaboration can be applied in order to create groups of industries with the same goal, negotiating with the shipowners in order to depress the monopoly created by them and getting economies of scale as well as other benefits like major time to execute the payment of the freight and free time on shipping.3. Comprehension about CTMPreliminary study about CTM dates from 1993 with the introduction of the ECR (Efficient Consumer Response) concept, when the agents of the Supply Chain started working in collaboration mainly with the use of the communication networks as EDI (Electronic Data Interchange) in order to improve the flows management from the suppliers until the consumers (Silva et al., 2009). With the intention to improve the application of the collaboration, CTM concept emerged to propose a new trade concept focusing on the transportation process. Therefore, the main objective of the CTM is to reduce or to eliminate the inefficiencies occurring in the transportation process (Esper and Williams, 2003). According to the authors, CTM aims to develop collaborative relations among the buyers, sellers, carriers and logistic operators (3 PLs) to increase service, efficiency and costs reductions associated with the transportation process.3.1 Potential CTM benefitsAs a consequence of CTMs use, companies have obtained reductions in costs transactions and risks, increased the service and capacity performance as well as obtained a more dynamical Supply Chain. A benefit of CTM is the reduction of uncertainties in the offer and supply through an improvement in the communication and collaboration among the partners of the chain. Another benefit found in the literature concerns about the visibility of the loading status (waiting time, execution time). It facilitates the management of the carrier service when permitting pro-active actions and, thus CTM allows freight prices economies, reductions in human resources and the improvement in the service level offered to the clients.4. Choosing a method to deal with the studys problemThere is not a pattern model to be followed in order to attract companies to get into a collaborative distribution chain. In this case it is possible to extend this truth to the maritime transportation problem in the exportation chain, which still has only few published scientific studies, especially for the Brazilian scenario. So, the challenge is to find a better way to deal with this problem. In order to determine an appropriated method to study the behavior of the collaboration in the exportation process a foregoing study was developed by Silva et al. (2011). In such study the methods System Dynamics (SD) and Agent Based Modelling and Simulation (ABMS) are presented due both of them are indicated to model systems containing large numbers of active objects (industries, people, vehicles, warehouses, products) and their applications vary according to the required level of abstraction, which can consider more or less involved details. These authors consider that logistic and supply chain problems involve several elements which cannot be modeled with such detail (varying from medium to high level
