摘　　要： 石油化工属于流程工业的范畴,其生产过程与离散制造业的生产过程有本质上的不同,需要不同的建模和优化方法,以及生产计划和调度的技术。经研究后,发现基于仿真的优化适合解决此问题。鉴于炼油生产问题的不确定性和复杂性,本文采用面向对象分析的方法,对炼油生产的一次加工过程进行建模分析,在此基础上采用eM-plant建立起该问题的仿真模型。通过仿真实验可以辅助手工的排产,也可以判断排产算法得到的计划是否可行,如计划不可行时提示出错的相关信息,为排产算法的修正提供帮助。 Petroleum refining industry belongs to flow industry,its production process is different from discrete manufacture's,so it not only need some different methods of modeling and optimization,but also need some new techniques with regard to production planning and scheduling.Optimization based on simulation is found out to solve this problem after some researches.Due to the uncertainty and complexity of oil refining,Object-Oriented Analysis(OOA) is used to build the simulation model of the first process of oil refining,which is based on eM-plant.With the result of a simulation experiment about the plan gained by sequencing arithmetic,worker can make a plan by manual more easily;also it can be judged whether this plan is feasible,if it is not feasible,some information about warning would showed out,which is useful to correct the sequencing arithmetic.
