A Service-Oriented Approach to Freight Routing in Intermodal Transport Systems

Determining optimal routes for given freight is a core decision inlogistics. In intermodal logistics, freight routing has to considerthe interfaces between different modes of transportation, such ashand-over offsets, load changes, and organizational procedures.We study this problem from the perspective of Service-OrientedComputing (SOC). We (1) propose representing intermodaltransport systems as a set of service offerings and customerdemand as service requests, (2) define freight routing as a servicecomposition problem, and (3) develop a composition algorithmfor transportation services

Modeling the Multicommodity Multimodal Routing Problem with Schedule-Based Services and Carbon Dioxide Emission Costs

We explore a freight routing problem wherein the aim is to assign optimal routes to move commodities through a multimodal transportation network. This problem belongs to the operational level of service network planning. The following formulation characteristics will be comprehensively considered: (1) multicommodity flow routing; (2) a capacitated multimodal transportation network with schedule-based rail services and time-flexible road services; (3) carbon dioxide emissions consideration; and (4) a generalized costs optimum oriented to customer demands. The specific planning of freight routing is thus defined as a capacitated time-sensitive multicommodity multimodal generalized shortest path problem. To solve this problem systematically, we first establish a node-arc-based mixed integer nonlinear programming model that combines the above formulation characteristics in a comprehensive manner. Then, we develop a linearization method to transform the proposed model into a linear one. Finally, a computational experiment from the Chinese inland container export business is presented to demonstrate the feasibility of the model and linearization method. The computational results indicate that implementing the proposed model and linearization method in the mathematical programming software Lingo can effectively solve the large-scale practical multicommodity multimodal transportation routing problem

A metamodelling approach for performance evaluation of intermodal transportation networks

The paper proposes a metamodelling procedure devoted to provide a reference model to be used by decision makers in the performance evaluation of Intermodal Transportation Network (ITN). In order to obtain a generic model describing a nonspecific ITN from the structural and behavioural point of view, the metamodelling approach consists in applying a top down and modular procedure. The model is specified by the well known Unified Modelling Language (UML), a graphic and textual modelling formalism intended to describe systems from structural and dynamics viewpoints. Hence, the paper models a generic ITN starting from the network description and shows by a case study the metamodel of one of the most important nodes that compose it: the port subsystem. Moreover, the case study model is translated in a simulation software and the performance measures obtained by the simulation results are shown

Integrating operations research into green logistics:A review

Logistical activities have a significant global environmental impact, necessitating the adoption of green logistics practices to mitigate environmental effects. The COVID-19 pandemic has further emphasized the urgency to address the environmental crisis. Operations research provides a means to balance environmental concerns and costs, thereby enhancing the management of logistical activities. This paper presents a comprehensive review of studies integrating operations research into green logistics. A systematic search was conducted in the Web of Science Core Collection database, covering papers published until June 3, 2023. Six keywords (green logistics OR sustainable logistics OR cleaner logistics OR green transportation OR sustainable transportation OR cleaner transportation) were used to identify relevant papers. The reviewed studies were categorized into five main research directions: Green waste logistics, the impact of costs on green logistics, the green routing problem, green transport network design, and emerging challenges in green logistics. The review concludes by outlining suggestions for further research that combines green logistics and operations research, with particular emphasis on investigating the long-term effects of the pandemic on this field.</p

Container Port Selection by Freight Forwarders in Central and Eastern Europe Hinterland: the Case of the Czech Republic

Containerization and port regionalization strategies have impacted the level of port competition in contestable hinterlands. However, the nature of this competition usually involves a single maritime range and well-defined transport corridors. The European context has underlined a complex dual range competition dynamic particularly involving the Northern Range and the Mediterranean. How these dynamics pan out in Central and Eastern Europe has received much less attention but will impact the growth prospects of ports on both ranges. This research study evaluates the importance of port selection factors by freight forwarders in the landlocked Czech Republic. It is based on a survey of key actors, particularly how specific carriers and ports are selected and which transport chains are used. The importance and stability of the factors are analysed within the framework of four constraint layers – the location layer; the infrastructure layer; the transport layer and the logistics layer. The key factors supporting the dominance of the port of Hamburg with the Czech Republic are discussed in addition with the potential of the North Adriatic Port Range to service this contestable hinterland. Hamburg is characterized with lower inland haulage costs, total shipment costs and the highest inland rail frequency compared to competing ports such as Bremerhaven or Koper. These factors are perceived as the key determinants by freight forwarders. Therefore, evidence underlines that the share of Hamburg is likely to remain unchanged in coming years and that Northern Range ports are dominant to service most of the Central and Eastern European hinterland. The paper supplements the literature with the analysis of primary data from business practitioners regarding port selection strategies by international trade intermediaries and fills the research gap for the region of Central and Eastern Europe

Simulation framework of port operation and recovery planning

This study proposes a framework of simulation tool suites for ports to evaluate their response to disaster crisis and port security policies. The focus is containerized cargos that are imported through ports in the U.S. with final destinations also in the U.S. A crisis, such as a man-made or natural disaster, may cause a delay at the seaport. The down time of ports may result in severe economic losses. Thus, when a seaport cannot normally operate, it is important to minimize the impact caused by the disrupted freight flow. Port security policies also have a significant impact on the port operation efficiency. This model developed in this study evaluates the performance of re-routing strategies under different crisis scenarios and can help the user to find an effective re-routing decision and analyze security policies of a port. This model also analyzes security policies of the simulation port

Synchro-Modality and Slow Steaming: New Business Perspectives in Freight Transportation

The logistics sector faces substantial challenges in meeting customer demands for higher service quality, speed and flexibility under conditions of continued growth in world trade and worldwide transportation movements, increasing distances and vulnerabilities of the supply chain. Additional challenges relate to the economic and environmental sustainability of logistics operations. While a lot of attention was devoted in the past decades to the operational and technical aspects, the business development phase has been put aside, causing the market failure of several projects. The paper presents the SYNCHRO-modal supply chain eco-NET (SYNCHRO-NET) project, which will demonstrate the effectiveness of slow steaming combined with synchro-modality in reducing the cost and the emissions of international supply chains and improving reliability and sustainability through the optimization of the planning process. Differently from other similar projects, SYNCHRO-NET combines operational aspects with a business perspective and represents a stakeholder-driven approach aimed at developing a close-to-market solution over the timeframe of the project

Sustainable supply chain management in city logistics solutions: an experience's comeback from Cityporto Padua (Italy)

The sustainable logistics and transportation studies constitute a primordial research axis in the enterprises' governance. In the last years, many reflections and developments in logistics research have studied the economic and the environmental questions related to supply chain management, but only few of them consider sustainability in its totality. Moreover, in practice, city logistics systems conception and planning is currently following a sustainable approach. The aim of this paper is to start a reflection about the three dimensions of sustainable supply chain management (economic, environmental and social), and illustrate these concepts by the results of an experience's comeback from a city logistics system, Cityporto (Padua, Italy).Sustainable Supply Chain Management; experience's comeback; urban freight distribution
