Optimization of oil-mixture “hot” pumping in main oil pipelines

The optimal conditions for high pour point and high-viscosity oil transportation through the main oil pipeline sections are determined. The optimization of "hot" pumping is investigated by determining the energy-saving operating conditions of pumps and heating furnaces. The objective function of optimality for the pipeline section with several stations is determined by a minimum costs of energy consumed by pumps and heating furnaces. The problem solving algorithm is constructed by new dynamic programming approach. The problem is divided into many overlapping subtasks with finding the optimal substructure. The object of each subtask is the cost function of pumps and heating furnaces at the stations.
