Refinery production planning and scheduling: the refining core business

intelligent production planning and scheduling are of paramount importance to ensure refinery profitability, logistic reliability and safety at the local and corporate levels. in brazil, such activities play a particularly critical role, since the brazilian downstream model is moving towards a demand-driven model rather than a supply-driven one. moreover, new and specialized non-linear constraints are continuously being incorporated into these large-scale problems: increases in oil prices implying the need for processing poor quality crudes, increasing demand and new demand patterns for petroleum products, new stringent environmental regulations related to clean fuels and start-up of new production technologies embedded into more complex refining schemes. this paper aims at clarifying the central role of refinery planning and scheduling activities in the petrobras refining business. major past and present results are outlined and corporate long-term strategies to deal with present and future challenges are presented.
