摘要:

目前,原油采购和混炼加工方案多采用人工经验或数学规划方法进行决策,存在求解时间过长以及无法统筹考虑全局性等问题。针对炼化场景下的典型混炼工艺和原油采购要求,结合“P模型”的概念建立了混合整数非线性模型,并根据整数变量的特性设计了基于p范数和内点法的迭代求解算法。结果表明,在10种原油、54种物性、58套加工装置的优化背景下,与商用求解器优化结果相比,采用以上方法可以在短时间内找到一个经济效益更好的原油采购加工方案并且在多个算例下均展现出了更好的鲁棒性。

Abstract:

At present, the decision-making process for crude oil procurement and mixing processing plans relies heavily on manual experience or mathematical planning programming methods, which suffer from issues such as long solution times and inability to consider the overall context. To address these issues, we proposed a mixed-integer nonlinear programming model incorporated the “P model” concept, specifically tailoring for typical mixing processes and crude oil procurement needs in refining scenarios. Additionally, an iterative solution algorithm based on p-norm and interior point method was designed based on the unique characteristics of integer variables. The results showed that, under the optimization background of 10 crude oils, 54 physical properties, and 58 processing units, our method outperformed commercial solvers in terms of both speed and economic efficiency. Furthermore, our approach exhibited superior robustness across multiple scenarios.

Key words: optimization, algorithm, petroleum, mixing processing, bilinear, interior point method, norm smoothing
