摘要

在石油化工行业，上下游企业的联合生产是供应链优化的主要途径和重要手段。但由于石化企业的生产工艺过程复杂且设计相互独立，企业间的协同生产往往仅存在于大型石化集团统一设计、建造的炼化联合生产系统中。本文提出了适用于独立运营的石化企业集成的前提条件和建模方法，以独立生产的炼油厂和烯烃厂为研究对象，基于其生产物流计划模型，建立统一的联合生产计划优化模型。该集成优化模型为混合整数线性规划模型，以生产效益最大化作为优化求解目标，并分析了市场需求平稳、萎缩和旺盛3种不同的案例场景。实例计算表明，同独立生产相比较，石化企业的集成优化和联合生产能够降低物料存储成本和总成本，节省优化求解所需的计算资源，并促进经济效益的提升。

Abstract

The synergetic production among upstream and downstream enterprises is a critical step toward supply chain optimization across petrochemical industry. However

because of complexity and independent design of petrochemical process

such a synergetic operation between facilities is available only in a few conglomerate corporations with coordinated manufacturing systems. An optimized model for integrated logistic planning in independently operating petrochemical companies was proposed on a basis of current supply chain model of independent refinery and olefin plants. In this mixed-integer linear programming (MILP) model

maximum operation profit was targeted as optimization condition and analyzed in three scenarios corresponding to normal

depressed and active marketing demands. Results of case study showed that

compared to independent operations

the integrated optimization and united operation among petrochemical companies could reduce material storage and overall cost

improve resource allocation

and increase operation profit.
