针对数学规划方法应用在原油调度中对非线性约束和连续变量处理的局限性,通过分析约束规划方法解决问题的原理、建模方式和搜索机制,指出了应用约束规划方法解决原油调度问题的可能性和优势;并针对实际问题,分别应用两种方法进行建模、求解．通过对结果的分析得出,约束规划方法建模简单,可直接处理非线性问题,对连续变量和整型变量都可以很快求得可行解。
Aimed at the limitations of mathematic programming methods in crude oil dispatching for nonlinear constraints and continuous variables processing, this paper analyzes the principle, modeling method and search mechanism of constraint planning methods to solve the problems, and points out the possibility of using constrained programming methods to solve the crude oil dispatching problems And advantages and disadvantages; and for the actual problems, respectively, two methods were used to model and solve. Through the analysis of the results, it is concluded that the constrained programming method is simple and can directly deal with the nonlinear problems. The feasible solutions can be obtained quickly for both continuous variables and integer variables.
