Structural optimization of multimodal routes for cargo delivery

Abstract

This article is devoted to the coordination of single stages of the multimodal delivery process, taking into account the fact that the process is discrete in its content. The tact, which has the content of a time window for performing the operation is used for discrete processes. Due to the fact that multimodal transportation of goods is carried out on a large network, time is one of the most important criteria for their perfection. Two timing criteria are applied in the article, which take into account the fact that the multimodal process must be synchronized and that the transportation of a large group of goods can be carried out in separate parts. An estimation criterion was also applied, which takes into account constant, variable, contingent costs, which are carried out depending on the structure of the process. The goal of the study is to create such multimodal cargo delivery routes that are characterized by the highest level of selec-tion criteria. In contrast to known studies, the dependence of the optimization criteria of the multimodal process on the total volume of cargo delivery was shown. The method of analyzing the transport scheme of multimodal transportation and the corresponding algorithm and computer program were developed. The methodology involves a complete review of all possible route options using three types of continent transport, namely road, rail, and river. The method of struc-tural optimization is applied to the example of a transcontinental transport corridor.

Sustainable Development of Intermodal Freight Transportation—Through the Integration of Logistics Flows in Ukraine and Poland

“…The solution of the intermodal freight transportation model involves finding the optimal path from the first node of the graph to the nth. The initial move from the first node provides a Constraint (4), and the final entry to node n is provided by a Constraint (5).…”

“…The theoretical, methodological, and practical aspects of the state policy for the development of the transport industry in Poland and Ukraine were studied based on current scientific publications [1,2,9,10]. The methodological basis of this study relied on works [3][4][5][6][7][8][11][12][13][14][15], which are dedicated to network modeling of supply chains and optimization of intermodal container transport.…”

“…The theoretical, methodological, and practical aspects of the state policy of the transport industry's sustainable development in Ukraine were studied thoroughly by many scientists [1][2][3][4][5][6]. International cooperation and integration into the international transport system are considered important components according to the definition of regulatory mechanisms and directions for improving its integrity.…”

Pursuing Optimization Using Multimodal Transportation System: A Strategic Approach to Minimizing Costs and CO2 Emissions

“…Despite entailing substantial upfront investments, the multimodal system stands out for its operational efficiency and reduced environmental impact, outstripping the advantages of solely land-based transportation. This preference is substantiated by its capability to curtail greenhouse gas emissions and preserve road infrastructure due to the alleviated burden on truck traffic [9].…”
