摘　　要：针对汽油调合过程中组分油存在的不确定性,结合Ethyl RT-70汽油调合质量指标模型,形成约束条件带随机变量的汽油调合随机规划问题。存在不确定性的情况下,为使调合后的成品汽油更好地满足性能指标要求,采用随机规划方法对汽油调合问题进行优化,并做了仿真试验。仿真结果表明,采用随机规划方法求解汽油调合优化问题是可行的,不仅可以满足质量指标要求,还可以获得较高的经济效益。According to the uncertainty of feedstock and combining with the Ethyl RT-70 blending models of some important properties of gasoline, the gasoline blend optimization problem with uncertainty variable in the constrain is produced. The stochastic programming method is usd to get better operation point under the existence of stochastic disturbance. The simulation example shows that the proposed method is feasible, and can acquire higher economic benefit as well as satisfy the quality requests.
