Abstract
The design of intermodal freight terminals requires extensive research and a thorough analysis of the technical, financial and organizational aspects. In the paper, the operation of the reposition of large cargo containers (one of the types of intermodal transport units, ITUs) on the dedicated places is subjected to a discussion. The analysis is carried out with the use of a vehicle equipped with a telescopic arm, such as a reach stacker. The considered storage facility is reduced to a block characterized by spatial accumulation given in the paper. The description of the procedure for the execution of the handling operation from the arrival of a tractor-trailer with a container into a terminal, followed by the ITUs being set aside in a dedicated place and, in the end, the departure of the truck without load, is given in the paper. The activities are described in detail in order to present a descriptive model of particular operations upon entry to the intermodal freight terminal. Moreover, the paper contains relevant figures illustrating the various steps of realization and the analysis of duration of activities supported by actual realizations. The durations of the individual activities described in the paper are experimental, and the results have been validated on real-world intermodal freight terminals. Therefore, the authors believe that the obtained values may be used in analytical, simulation and numerical models of intermodal freight terminals.
Highlights
The design of inland intermodal freight terminals (IFT, known as land container terminals) requires a knowledge of logistics and transportation processes related to the operation of such facilities.This requires a knowledge of technical equipment, functional and spatial systems or even the duration of individual activities related to the operations of intermodal transport units in an intermodal freight terminal
The subject matter of the paper was to present the process associated with the operation conducted on intermodal transport units, for example a large type A container, including inter alia: simple operations and combinations of operations connected to containers service in intermodal freight terminals, such as: handling, raising a load unit from a tractor-trailer, placing it into the appropriate sector in the storage area of a terminal, etc
The handling and transportation of intermodal transport units upon entry into an intermodal freight terminal is an important element characterising the total cargo handling cycle, from the arrival of the cargo into the transhipment terminal until its release. In view of this matter, it is important that the description of the handling and transportation cycle would take into account the important elements that have an actual impact on the size of such a logistics facility (IFT) and the duration of the cargo operation
Summary
The design of inland intermodal freight terminals (IFT, known as land container terminals) requires a knowledge of logistics and transportation processes related to the operation of such facilities. The content of the paper has been prepared to discuss the elementary components of the process and to analyse the duration of handling and transport operations from taking a large cargo container from a tractor-trailer using a reach stacker to the placement of a load unit at the appropriate layer of the sector at a storage yard in an intermodal freight terminal. The issues specified in the paper are given to increase the knowledge related to the operations in terminals involving intermodal transport, and they are an important element to simulate the operating process of a particular logistics facility (as planned for future research).
