成品油管道总体工艺方案优化设计

针对成品油管道的特点，在对其工艺方案优化设计问题进行系统分析的基础上，选择了一组数目最少、关联程度最低的决策变量，建立了单根无分支的成品油管道工艺方案优化设计的数学模型。该模型的最优准则是：管道在设计寿命期内所需的总费用现值最小。总费用现值包括管道初试投资费用，运行维护费用现值和能耗费用现值。该模型是一个非线性混合整数规划问题，决策变量为管材，管径和出站压力，约束条件主要有水力约束条件，强度约束条

A Mathematical Model for the Optimal Design of Oil Product Pipeline

Based on the system analysis,a mathematical model is established for the oil product pipeline. In the model,the minimum total discounted cost during the whole life of the pipeline is taken as the optimal criterion. The tatal cost includes initial investment,discounted operation and maintenance costs and discounted power costs. This model is a complex of nonlinear programming and integer programming. The decision parameters are pipeline material, diameter, and outlet pressure; the constraints are hydraulic constraints, strength constraints,pump station performance constraints,and line pipe specification constraints.
