Abstract: Abstract：Through close integration between new technologies, such as information technology and traditional petrochemical industry, new refinery-technology breakthroughs have been made to realize intelligent manufacturing and information integration, and improve production and management efficiency and lower production cost. The development trends of planning and optimization in refining and petrochemical industry is to realize the integration of various sectors, to simulate the process of production and operations relying on models and make planning more close to reality. Combining the design of the Advanced Planning System of PetroChina , this paper introduces the overall planning design of a multi-plant model, including various ways of expression of different aspects（raw material supply, production, transport and logistics, inter-company feed, product sales and inventory）in the model.

摘要： 摘 要：通过信息技术等新技术与传统炼化产业的紧密结合推动炼化技术实现新突破，实现智能化生产和信息集成，提高生产和管理效率，降低生产成本。炼化行业计划优化技术发展趋势是实现生产计划各环节的集成，依托模型对生产和经营过程进行模拟，增进计划的科学性。本文结合中国石油总部先进计划系统的设计，介绍了多厂模型的总体设计方案，包括原料供应、生产、物流运输、互供料、库存及产品销售等各环节在模型中的表现方式。
