Container throughput forecasting plays an important role in port capacity planning and management. Regarding the issue of container throughput of Tianjin-Hebei Port Group, considering the container throughput is an incomplete grey information system affected by various factors, the effect is often unsatisfactory by adopting a single forecasting model. Therefore, this paper studies the issue by combining fractional GM (1, 1) and BP neural network. The comparison results show that the combination model performs better than other single models separately and has a higher level of forecasting accuracy. Furthermore, the combination model is adopted to forecast the container throughput of Tianjin-Hebei Port Group from 2021 to 2025, which would be a data reference for the future development optimization for the container operation of Tianjin-Hebei Port Group.

Container Operation

The effects of a container operation on a traditional steamship company are discussed, and the need for planning emphasized. The "optimum" containership is defined, and the naval architect's role in its determination is outlined. The two basic approaches to optimizing a system are described, and the limitations of each approach stipulated. An algorithm which estimates both capital and operating costs for containerships is presented, together with relationships for capacities, weights, and dimensions. (The computer program is appended.) A typical algorithm output is presented, and its application to two basic types of optimization studies is described.
