英文摘要： Nowadays, oil-refining industry in China is facing great pressure for its development. To ensure its sustainable and stable development, it is crucial to improve its profit margin and reduce operating cost. The key issue on profit margin maximization and operating cost minimization is to reasonably purchase crudes and high-effectively utilize cheap crudes. This project is to carry out research on modeling and global optimization of integrated crude oil procurement and scheduling of operations. First, the relationship between crude oil procurement and crude blending and scheduling operations is explored. Based on the relationship, a general network diagram for the integrated crude oil procurement and scheduling operations is developed. Then, a non-convex mixed-integer nonlinear optimization formulation is proposed to model the network. Second, the piecewise-linear relaxation technology is applied to relax nonlinear terms and develop tight piecewise-linear relaxation formulation for this project. Combining with spatial branch and bound algorithm, a global optimization algorithm incorporating piecewise-linear relaxation model and software package are developed, and global optimality is theoretically guaranteed. Several large-scale industrial examples are solved to generate and demonstrate optimal schedules for crud
