| 目的 解决多停泊基地背景下拖轮与船舶之间供需不匹配、需求响应时效要求越来越高以及各基地拖轮使用不平衡等问题。方法 本文考虑多拖轮基地的影响，在对拖轮线路调度的基础上进行区域调度，采用对拖轮进行跨基地重调度的方法，以总调度成本最小为目标建立拖轮重调度模型。结果 将天津港数据搜集分析作为本文案例对模型进行验证分析，结果显示，采用区域调度后成本低于单纯的线路调度，且拖轮工作时间基尼系数值为0.2～0.3，处于比较公平的状态。结论 此模型有效地降低了拖轮调度成本和在港船舶等待时间，平衡了拖轮使用时间。 |

| The work aims to solve the problems of mismatch between supply and demand of tugs and ships, increasing demand response timeliness requirements, and unbalanced use of tugs in various bases. Considering the impact of multiple tug bases, regional scheduling was carried out on the basis of tug line scheduling, and a tug rescheduling model was established with the goal of minimizing the total scheduling cost by adopting the method of cross-base rescheduling. With the data collected and analyzed from Tianjin Port as the case, the model was verified and the results showed that the cost after regional scheduling was lower than that of simple line scheduling, and the Gini coefficient of tug working time was 0.2 ~ 0.3, which was in a relatively fair state. The model effectively reduces the cost of tug scheduling and the waiting time of ships in port, and balances the use time of tugs. |
