摘　　要：针对炼油过程的平稳性和长期性等生产特性,研究了其优化调度问题。给出了平稳性和长期性的定义,并对生产特性进行了模型化描述。提出了生产的平稳度、长期度性能指标,以实现生产特性的量化表达和评价。在此基础上建立了炼油过程的广义析取规划优化调度模型。以某炼油过程生产调度为例,对比有无体现生产特性的优化调度仿真结果表明:基于炼油过程生产特性的优化调度模型能够提高生产特性性能,得到的调度方案更为可行和实用。The scheduling optimization problem of refinery processes was studied in view of the production characteristics such as stability and chronicity whose definitions are given first.Based on the given definitions,production characteristics were described using disjunctive normal form and logic proposition.To evaluate production characteristics quantitatively,the performance criterion of stability and chronicity were proposed.Finally,based on expressions of production characteris-tics,a generalized disjunctive programming scheduling optimization model was set up.Simulation results obtained from the scheduling of a certain refinery having expressions of production characteristics whether or not show that the scheme of the production characteristics based scheduling model can improve the performance of production characteristics and is feasible and practical.
