The integration of processes and systems related to logistics inside the companies and together with their suppliers and customers has been established as a trend in the past few years. The use of logistics as a competitive advantage and to add value to the products and services has become, more and more, one of the strategic issues for the companies. More recently, the collaborative planning has been widely applied as a tool to achieve productivity and cost advantages. In today’s business environment, the information flow between the supply chain members, as well as the quality and visibility of the information is a key issue to support decision making. The great development of information technology and information systems in the last decades has contributed, decisively, to provide appropriate information flow across the supply chain members. Companies need to set up technologies and information systems that assure an agile and high quality information flow in order to enable a quick reaction to the increasing challenges of business. This work aims to, based on the theoretical foundation of supply chain and information technology, analyse the information flow for the refined oil products process at Petrobras, identify the main issues due to inappropriate information flow, in terms of timing and information quality, and propose technologies and information systems solutions to solve the issues.
