基于事件逻辑的炼油企业动态调度系统

Dynamic Scheduling System Based on Event Logic for Oil Refineries

摘要:

针对炼油生产动态调度问题,开发了基于事件逻辑的调度优化系统.在分析大量实际生产事件和调度专家处理经验的基础上定义动态事件,生成事件逻辑.将事件逻辑与广义析取规划相结合,建立了基于事件逻辑的动态调度模型.基于事件逻辑的动态调度建模方法增加了动态调度模型生成的快速性和灵活性,在保证调度优化性的同时获得较好的调度实时性.最后,以某炼油厂“原油供应不足”事件为例进行仿真实验.结果表明,基于事件逻辑的动态调度系统是可行、有效的.

Abstract:

A dynamic scheduling system for oil refineries was developed based on event logic.Dynamic events were defined and corresponding event logics were generated by analyzing practical production event characteristics and event treatment experiences of scheduling experts.Based on event logic and generalized disjunctive programming,a dynamic scheduling model was constructed.The event logic based modeling method can raise the rapidity and flexibility to formulate dynamic scheduling models,and can give a better solution to meet realtime requirements and optimization performance.The developed dynamic scheduling system was used to address the scheduling problem of an oil refinery with an event of crude oil shortage.Numerical results show that the event logicbased dynamic scheduling system is feasible and effective.
