This work shows a new approach to solve dynamic and complex logistics problems based upon the fact that in human society several problems are solved by interaction and negotiation between humans, that alone can't solve the problem, but if they join themselves toward the solution of the problem, all of them with their own resources and capabilities, they can reach one solution. It is proposed and defined one methodology inspired by the human society way of solving problems using several negotiation protocols. It was also proposed a negotiation protocol inspired in human emotion gratitude that has the main goal to solve the conflicts that might occur. Based on this proposed methodology, it was developed a computational system to create a virtual society of agents that have their own resources, non shareable, and by the exchange of messages between the agents, they converge to schedule all the solicitations of operations received (ship to load or unload container). This system was developed based on the agent technology and multiagent system. The proposed methodology and the implemented system were applied to a practical and real application of a Maritime Container Terminal. Several tests were done and the results was shown and analyzed for each negotiation protocol.
