| 中文摘要:针对沿海地区燃料油供应问题，制定燃料油配送方案，设计配送航线和配送量使运输成本和库存成本最小，同时考虑需求不确定的情况，使需求发生一定变动时原方案依旧可行。与不考虑需求不确定的供应方案相比，使用鲁棒优化方法得到的结果可靠性更强，发生缺货的可能更小。由于需求不确定情况下存在的二次约束严重影响模型的求解效率，提出一种两阶段求解方法来分解问题，使求解效率得到明显提高。对于存在需求不确定情况的供应系统，决策者使用该鲁棒优化模型时，可以根据风险偏好并通过调整参数最大限度地提高供应方案的可靠性。 |

| Robust optimization of short sea fuel oil distribution under demand uncertainty |

| Abstract:Aiming at a fuel oil distribution issue in short sea, the fuel oil distribution scheme is developed, the distribution route and distribution quantity are designed to minimize the transportation cost and inventory cost, and the uncertain demand is taken into account in order that the scheme is able to stay feasible when the demand uncertainty happens.Comparing with the scheme under deterministic demand, the scheme developed by the robust optimization method is more reliable and less likely to occur out of stock. Because the quadratic constrain under the demand uncertainty makes the solving efficiency terrible, a two stage solving method is proposed to decompose the problem, which improves the solving efficiency greatly. For the distribution system under demand uncertainty,when decision makers adopt the robust optimization model, the reliability of the distribution scheme can maximize according to their risk preference and through adjusting the parameters. |
