| 成品油管道工艺方案优化设计的目标是使所设计的管道在其计算期内经济效益最佳，由于影响工艺方案的因 素较多，设计人员通常期望能够通过优化的方法获得多个预选方案，然后就一些影响因素和工程实际情况进行具体 分析后，再确定最优工艺方案。以成品油管道系统计算期内总费用现值最小为目标函数,建立了管径优选数学模 型,并应用动态规划法进行了求解。在求解时，把泵站投资表示为水力摩阻的函数，使得求解变得简单方便。具体 的实例结果表明，同其他方法相比，应用动态规划法能够同时求解出最优和次优工艺方案，所得结果可以用于多方 案比选。 |

| Abstract: |
| The objective of products pipeline optimal process design is to make the most benefit from expected economic life under conditions of constraints satisfaction. The factors influencing the decision of the optimal process alternative are lots, so the designer usually expects to obtain some optimal alternatives at the same time. Then based on economic and technical comparison, the final design alternative is selected. Aiming at the minimum total discounted cost in the life expectance of products pipeline, an optimal design model was established. The dynamic programming was employed to solve the model. Furthermore the investment of pump station was expressed as the function of hydraulic resistance. The algorithm was tested by a real example. The results show that compared with the other methods, it has the advantage of obtaining the optimal and the quasi-optimal scenarios at the same time. Designers can use these scenarios in comparison. |
