Multimodal transport information sharing platform with mixed time window constraints based on big data

摘要

The primary consideration in the top-level design of multimodal transport systems is the matching degree and coordination degree of port facilities and transport information platforms. In the process of container transportation, there exists a mixed time window consisting of a hard time window and a soft time window. This study focuses on the coordination of transport organization considering the scale effect under the constraint of a mixed time window. It is necessary to consider the influence of the mixed time window on transport efficiency. Highway transportation is relatively flexible and can be regarded as without time window constraints. Railway transportation and waterway transportation have relatively fixed delivery and operation times, reflecting hard time windows. Alternatively, the time interval of a consignee receiving goods is relatively free, reflecting a soft time window. The process of container transportation involves a mixed time window consisting of a hard time window and a soft time window. The scale effect of transportation is the result of a combination of internal and external factors. This paper will discuss the functions and operational statuses of the relatively independent information system of railways and ports and establish an electronic platform suitable for information interconnection and the interoperability of multimodal transport stations in combination with the traditional information exchange mode.
