基于原油类型聚类泊位分配的港炼一体化调度模型OA

To address the problems of frequent tank switching,increased inventory costs,and discontinuous feed-stock supply to units caused by the neglect of the coupling relations among port operations and various production stages in traditional sequential optimization approaches for refinery-wide scheduling,a berth allocation strategy based on concentrated unloading by crude oil type and an event-based hybrid-time modeling approach are adopted to develop an integrated terminal-refinery scheduling model encompassing berth allocation,crude oil unloading,tank scheduling,distillation processing,secondary processing,and product blending.The model comprehensively characterizes the linking constraints between port unloading and tank inventory,the sequential relationships between tank switching and unit feeding,and the coupling mechanisms between crude oil blending and product quality,and a normalized multi-parametric disaggregation technique is employed for model solution.Case study res-ults based on actual data from a refinery enterprise demonstrate that the proposed model effectively optimizes berth allocation and crude oil unloading sequences,and significantly improves the operational state of downstream pro-duction stages,including tank inventory management,crude distillation unit feed continuity,secondary processing unit operations,and finished product blending.Compared with traditional sequential optimization approaches,the model effectively reduces total operating costs and improves scheduling efficiency.
