The role of collaboration through manufactured goods' exportation process under System Dynamics analysis

摘要

In the recent years, there has been an increasing interest by the countries in expand their exportation volume. Although large amount of goods are exported, in some countries as Brazil, the major contribution in the exporting balance is derived from the primary goods. Thus, a possible way to increase the country's wealth is to increase the participation of added-value goods. In this context, the aim of this study is to present a new approach to analyze the behavior of the collaboration in the maritime transportation in order to reduce freight costs pertinent to the manufactured goods' exportation process. Firstly, the general exportation process is described considering the main agents involved in the logistic chain. In the sequence, two possible methods to model and analyze such problem are described (Agent Based Modeling and Simulation - ABMS and System Dynamics - SD). After a comparison between both methods, SD method is chosen as the best appropriated and its primary implementation considering causal-loop diagram is presented. As a further step, a stock-flow diagram is developed, considering the main dynamic variables included in the exportation process, permitting a better comprehension of the transportation supply-demand mechanism, freight price definition and the collaboration formation.
