The port is a vital component for the economy of a nation. It incorporates a global transport system and considered as one of the logistic links which contributes in the creation of the value chain. Its complexity is accentuated because of the globalization and of the large number of operators whose contradictory objectives. Therefore, a permanent competitive environment had been created between supply chains. The main challenge for the harbor planning and development policies is thus to maintain a competitive level and ensure its efficiency.
This latter is assessed by qualitative and quantitative economic approaches which are mainly applied in the case of container ports. Indeed, few studies have been done on oil port performance. In addition, these studies do not evaluate either the global behavior of the port or the relationships between its components. Although an oil port meets all the criteria of an ordinary port, it is also subject to specific security requirements. Thus, a particular attention should be given to its management.
The aim of this work is to present an integrated framework for the optimization of the port logistics chain. This framework is an approach for understanding the port system under a global vision in order to promote its competitiveness and improve its value chain. This process uses the systemic and the stakeholder approaches at its first part. It uses the system dynamic theory in order to model and simulate the relationships.
The “port authority” and “transport department” relationship illustrates the influence of the latter in the land pre-carriage. Taking into account the risk and the infrastructure construction cost, an exclusively pipeline network is drawn which restraints the use of tankers. The “transport department” decision making uses the "?-constraint" technique to deal with the biobjective problem according to a spanning tree network design.
Therefore, this conceptual framework for the understanding and the optimization of the logistic chain management of a petroleum port is a decision support tool for all its stakeholders.
