以逐次二次规划（ＳＱＰ）为核心所开发的化工流程优化方法虽已取得不少进展，但 还存在两个方面的问题：原问题中相容的非线性约束在化为二次规划的线性约束时会出 现不相容的情况；未知变量的标度系数难以确定。为了提高ＳＱＰ的有效性及可靠性， 本文对它作了进一步的探讨，并提出了解决方法。通过对一个闪蒸系统实例的计算分 析．证实了提出的改进算法是较为有效的。
Although some progress has been made in the optimization of chemical processes developed with successive quadratic programming (SQP), there are still two problems: the compatible nonlinear constraints in the original problem are linearized into quadratic programming Incompatibility occurs when constrained; scale factors for unknown variables are difficult to determine. In order to improve the validity and reliability of SQP, this paper further explores it and puts forward a solution. Through the calculation and analysis of a flashing system instance. The proposed improved algorithm is proved to be more effective.
