目的 同时考虑重箱和空箱运输，研究多周期情形下重箱运输需求及相关成本参数变化对空箱调运方案的影响。方法 考虑重箱需求的模糊性，以系统总成本最小为目标，建立空箱调运模糊规划模型，并转换为清晰等价形式进行求解。结果 租箱与空箱调运比随航次数的增加而变化明显，决策期为2个航次的租箱与空箱调运比约为4个航次时的6倍；系统总成本随着可信度的增大而增大，在可信度为0.5时总成本最小。结论 空箱调运在长期决策中更明显，空箱调运量与空箱调运成本反向变化，与堆存成本和甩箱成本同向变化，在一定范围内随着租箱成本进行反向变化。

The work aims to consider the loaded container and empty container repositioning at the same time, and study the impact of changes in loaded container repositioning demand and related cost on the empty container repositioning plan under multi-cycle conditions. The fuzziness of the loaded container demand was considered. An empty container repositioning fuzzy planning model was established with the minimization of the total cost of the system as the objective. Then, the model was converted into clear equivalent form for solving. The leasing and empty container repositioning ratio changed significantly with the increase of the number of cycles. The leasing and empty container repositioning ratio of double cycles was approximately 6 times that of the four cycles, and the total cost of the system increased with the increase of credibility. When the credibility was 0.5, the total cost was the lowest. The empty container repositioning is more obvious in long-term decision-making and the quantity of empty container repositioning changes in the opposite direction as the empty container repositioning cost, in the same direction as the storage cost and container dumping cost, and in the reverse changes with the leasing container cost within a certain range.
