成品油调和是石油炼制过程中的重要环节,直接影响炼油企业的经济效益。本文以石化行业为背景,针对成品油调和配方优化问题进行了研究,在满足成品油质量指标约束的条件下,以最小化企业生产成本为目标,建立了混合整数规划模型,提出了基于遗传算法的有效求解策略,并根据某炼油厂的实际生产数据进行了仿真实验,计算结果反映了库存成本与启动成本之间的平衡关系,即:当单位库存成本不变,单位启动成本逐渐变大时,库存总成本随之增大,启动次数随之减少。反之,当单位启动成本不变,单位库存成本逐渐变大时,启动次数随之增大,库存总成本随之减少。
成品油調和是石油煉製過程中的重要環節,直接影響煉油企業的經濟效益。本文以石化行業為揹景,針對成品油調和配方優化問題進行瞭研究,在滿足成品油質量指標約束的條件下,以最小化企業生產成本為目標,建立瞭混閤整數規劃模型,提齣瞭基于遺傳算法的有效求解策略,併根據某煉油廠的實際生產數據進行瞭倣真實驗,計算結果反映瞭庫存成本與啟動成本之間的平衡關繫,即:噹單位庫存成本不變,單位啟動成本逐漸變大時,庫存總成本隨之增大,啟動次數隨之減少。反之,噹單位啟動成本不變,單位庫存成本逐漸變大時,啟動次數隨之增大,庫存總成本隨之減少。

Product oil blending is an important step for oil refining, which directly affects the economic benefits of oil refineries.Using petrochemical industry as background, this paper does a research on the optimization of the recipe for product oil blending.A mixed-integer programming model is developed to minimize the total production cost of the refinery on the condition that product quality indexes are satisfied, and an efficient solving strategy based on genetic algorithm is proposed.Then a simulation experiment is made according to the actual production data of an oil refinery and the balance relationship between the inventory cost and the setup cost is showed by computational results.To be specific, the total inventory cost increases and the number of setups decreases, when the unit inventory cost remaines constant and the unit setup cost increases.Conversely, the number of setups increases and the total inventory cost decreases, when the unit setup cost remaines constant and the unit inventory cost increases.
