Significant time saving enables schedulers to explore a greater number of options, resulting in a more effective and optimised scheduling plan.
#Logistics scheduler software software#
The software can solve autonomously the major components of the scheduling problem, requiring the user’s intervention only to manage significant issues requiring appropriate action.įurthermore, integration of economically driven optimisation methods generates operational plans to maximise the processing of opportunity crudes while meeting the CDU‘s feedstock quality requirements. This simulation highlights real bottlenecks to manage to prevent operational problems. The calculation engine manages the service requests associated with material transfers according to specified priorities and selection criteria, to bring each event to completion as fast as possible. Prometheus has developed a tool, Proraf, which offers an innovative algorithm to concurrently manage crude oil logistic events (reception, transfer, and processing) and predict the hourly evolution of the status of all tanks.Ĭrude data, simulation, and optimisation techniques are integrated by an algorithm which is also able to work high-level transfer instructions where the sequences of tank loading/unloading operations are not detailed.
Thus, optimisation of crude oil logistics is fundamental, especially when the available crude inventories are limited and it is difficult to segregate crude quality. Poor scheduling can erode up to 5% of the theoretical monthly result predicted by linear programming planning models and can result in higher ship demurrage costs. Batches fed to the CDU must fit both quality constraints set by the operations department and simultaneously maximise the content of opportunity crude oils for the best processing margin.
Generation of a refinery’s operations plan requires the capability to monitor and determine the quality and the composition of crude oil to be processed in the crude unit as well as its availability date.
