    While several road freight performance measurement systems have been developed, only a limited number of quantified performance measurement frameworks encompassing diverse sets of performance metrics from multiple sustainable perspectives are available on a technological platform. These sets of metrics could be integrated as crucial performance indicators for assessing the operational performance of various road freight transport companies. These indicators include fuel efficiency, trip duration, vehicle loading, and cargo capacity. The objective of this research is to construct a conceptual road freight performance measurement framework that comprehensively incorporates performance elements from sustainable viewpoints (economic, environmental, and social), leveraging technology to measure the performance of road freight transport companies. This proposed framework aims to aid these companies in gauging their performance using technology, thus enhancing their operations towards sustainability.Within the road freight transport sector, several challenges exist, with congestion, road infrastructure maintenance, and driver training and qualifications being particularly pressing issues. The developed performance measurement framework offers the means for companies to evaluate the effects of technology integration on vehicles and overall performance. This allows companies to measure their performance from an operational standpoint rather than solely a strategic one, thereby identifying areas requiring improvement. Egypt was chosen as the empirical study location due to its relatively low level of technological integration within its road freight sector.This thesis employs an explanatory mixed methods approach, encompassing four distinct phases. The first phase entails a review to formulate the proposed theoretical performance measurement framework. Subsequently, the second phase involves conducting semi-structured interviews using a Delphi method to both develop a conceptual performance measurement framework and explore the present state of Egypt's road freight transport sector. Following this, the third phase encompasses surveys based on the results derived from Delphi analysis, involving diverse participants from the road freight transport industry. The aim is to validate the developed performance measurement framework through an empirical study conducted in Egypt. Lastly, the fourth phase centres around organizing focus groups involving stakeholders within road freight transport companies. The goal here is to propose a roadmap for implementing the developed road freight transport performance measurement framework within the Egyptian context.The primary theoretical contribution of this research is the development of a road freight transport performance measurement framework that integrates the three sustainability dimensions with technology. Additionally, this study offers practical guidance for the application of the developed framework in various countries and contexts. From a practical standpoint, this research aids road freight transport managers in evaluating their operational performance, thereby identifying challenges, devising action plans, and making informed decisions to mitigate these issues and enhance sustainability-oriented performance. Ultimately, the developed road freight transport performance measurement framework is poised to promote performance measurement aligned with technology, fostering progress towards achieving the sustainable development goals by 2030

    Strategy Tripod Perspective on the Determinants of Airline Efficiency in A Global Context: An Application of DEA and Tobit Analysis

    The airline industry is vital to contemporary civilization since it is a key player in the globalization process: linking regions, fostering global commerce, promoting tourism and aiding economic and social progress. However, there has been little study on the link between the operational environment and airline efficiency. Investigating the amalgamation of institutions, organisations and strategic decisions is critical to understanding how airlines operate efficiently. This research aims to employ the strategy tripod perspective to investigate the efficiency of a global airline sample using a non-parametric linear programming method (data envelopment analysis [DEA]). Using a Tobit regression, the bootstrapped DEA efficiency change scores are further regressed to determine the drivers of efficiency. The strategy tripod is employed to assess the impact of institutions, industry and resources on airline efficiency. Institutions are measured by global indices of destination attractiveness; industry, including competition, jet fuel and business model; and finally, resources, such as the number of full-time employees, alliances, ownership and connectivity. The first part of the study uses panel data from 35 major airlines, collected from their annual reports for the period 2011 to 2018, and country attractiveness indices from global indicators. The second part of the research involves a qualitative data collection approach and semi-structured interviews with experts in the field to evaluate the impact of COVID-19 on the first part’s significant findings. The main findings reveal that airlines operate at a highly competitive level regardless of their competition intensity or origin. Furthermore, the unpredictability of the environment complicates airline operations. The efficiency drivers of an airline are partially determined by its type of business model, its degree of cooperation and how fuel cost is managed. Trade openness has a negative influence on airline efficiency. COVID-19 has toppled the airline industry, forcing airlines to reconsider their business model and continuously increase cooperation. Human resources, sustainability and alternative fuel sources are critical to airline survival. Finally, this study provides some evidence for the practicality of the strategy tripod and hints at the need for a broader approach in the study of international strategies

    Capacity Planning with Uncertainty on Contract Fulfillment

    Get PDF
    This paper focuses on the tactical planning problem faced by a shipper which seeks to secure transportation and warehousing capacity, such as containers, vehicles or space in a warehouse, of different sizes, costs, and characteristics, from a carrier or logistics provider, while facing different sources of uncertainty. The uncertainty can be related to the loads to be transported or stored, the cost and availability of ad-hoc capacity on the spot market in the future, and the availability of the contracted capacity in the future when the shipper needs it. This last source of uncertainty on the capacity loss on the contracted capacity is particularly important in both long-haul transportation and urban distribution applications, but no optimization methodology has been proposed so far. We introduce the Stochastic Variable Cost and Size Bin Packing with Capacity Loss problem and model that directly address this issue, together with a metaheuristic to efficiently address it. We perform a set of extensive numerical experiments on instances related to long-haul transportation and urban distribution contexts and derive managerial insights on how such capacity planning should be performed

    GREEN INVESTMENT OPTIONS IN FERRY, RO-RO AND RO-PAX INDUSTRY - From theory to practice

    Get PDF
    An increased focus on sustainability issues and climate change from customers as well as the whole society, jointly with more restrictive regulatory requirements, are triggering shipping lines to progressively adopt green strategies, aiming at reducing emissions and pursuing higher (energy) efficiency standards (Pallis and Vaggelas, 2019). In the shipping sector, the Ferry segment expresses global fleet of about 15,400 ships with a total gross tonnage (GT) exceeding 31 million, and globally transports about 4.27 billion passengers per year and 373 million vehicles; furthermore, it has a contribution on world GDP of 60 billion dollars and allows the employment of more than 1 million people (Interferry, 2019). Because of the importance of the traffic volumes handled both in terms of passengers and cargoes, as well as due to the related impacts originating from business operations, the Ferry, Ro-Ro and Ro-Pax industry is challenged to implement green strategies (Chang and Danao, 2007). Corporate Social Responsibility (CSR) paradigms and related theoretical constructs are expected to reshape future goals, strategies and implantation trajectories of major Ferry, Ro-Ro and Ro-Pax companies and improve firm performance (Lun et al., 2015). This PhD thesis scrutinizes green strategies and related investment options which are expected to allow Ferry, Ro-Ro and Ro-Pax group owners, operating European-flagged vessels, to reach sustainability goals without negatively affecting their economic/financial performance. The document proposes a conceptual framework that addresses the most promising green investment options which Ferry, Ro-Ro and Ro-Pax companies can exploit for making the business more sustainable, reducing environmental impacts and improving energy and material efficiency during day-by-day operations. Using insights from a systematic literature review conducted in the first sections of this PhD thesis, the most relevant green solutions widely investigated at academic level are examined and discussed for the purpose of this PhD thesis. After an exhaustive description of the state of the art and the state of the play regarding green investment options in Ferry, Ro-Ro and Ro-Pax industry, this PhD thesis proposes an analysis of the most effective green strategies and practices concretely developed and planned in the industry. Empirical evidence shows that the most promising investment options relate to ship propulsion systems, such as the adoption of hydrogen and fuel cells (Trillos et al., 2021), alternative fuels (Very Low Sulphur Fuel Oil, Ultra Low Sulphur Fuel Oil and Liquefied Natural Gas), efficiency systems for auxiliary engines and ship design solutions. As confirmed by outcomes gathered in our final empirical dataset, i.e., the “green” sample, among the different solutions analysed, the most adopted green investment options by European companies operating in Ferry, Ro-Ro and Ro-Pax industry are: a) the refitting of bulbous bow, aimed at the implementation of the current design of the hull to increase the overall hydrodynamics of the ship; b) the installation of onboard batteries as a source of energy for ship propulsion; c) the use of Liquefied Natural Gas (LNG) as alternative fuel for the ship propulsion, that contributes to a 100% reduction in sulphur oxides emissions, 80-85% of nitrogen oxides emissions, 95% of particular matter emissions and 20-30% of carbon dioxide emissions compared to HFO/MDO (Burel et al., 2013). The empirical analysis above mentioned is performed on 1,680 Ferry, Ro-Ro and Ro-Pax ships with flag from European Countries, with data gathered through IHS Maritime & Trade that holds the largest maritime ships database in the world, further integrated with data and information collected from several technical sources (e.g., news press, sustainability report and press release of European companies). Variables investigates within IHS Maritime & Trade regard the type of main and auxiliary engines and fuel type, hull materials, bulbous bow and other technologies and equipment aimed at mitigating the pollution and reducing harmful emissions. The outcomes shed light on the viability and feasibility of some green investments options by shipping companies operating in Ferry, Ro-Ro and Ro-Pax industry at European level. To deal with this limited result, due to the lack of comprehensive dataset capable to scrutinize the diverse green solutions implemented on board European-flagged vessels, it was decided to develop an original and detailed dataset, capable to provide additional information concerning the approaches, decisions and strategies adopted by each group owners and related future trends about the adoption of green strategies in the sector. Through the examination of different sources (e.g., news press, specialised journals, communications by the companies on their corporate website, academic papers, etc.), information related to innovative technical solutions and cutting-edge technologies for mitigating the pollution and reducing harmful emissions have been extracted for each ship of the database, i.e., the “overall” or “extended” sample. In this way, it has been possible to provide an exhaustive overview of the heterogeneous green solutions, equipment and components installed on board of ships that are part of the “green” sample and the related source, to allow the evaluation and examination from the point of view of the institutionalism of the source. In this way it was possible to focus on top ten best performer group owners of the “green” sample, to analyse the managerial and governance behaviours and attitudes implemented by them and to deepen in brief case histories the main strategies adopted by them

    Despite the pursued autonomous ships initiatives, the lack of information on emerging technologies and their costs along with the limited investigations of the autonomy effects on logistics render these vessels feasibility assessment challenging. This study aims at developing an overarching framework to support decisions for the transition to autonomous shipping. The ship lifetime capital, operational and voyage expenditures are estimated to quantify the economic-environmental impact and required investments. Several scenarios are defined to address the input data uncertainty. The case of a short-sea shipping cargo vessel operating in the Norwegian waters is studied, considering its conversion to operate autonomously, as well as the next generation crewless ship design. The derived results demonstrate that the converted autonomous ships can reduce the lifetime present value by 1–12% and the carbon emissions by 4%, whereas the new autonomous design leads to their further reductions by 3–4% and 4–7%, respectively. These savings can further increase by 6–7% by reducing the autonomous ships sailing speed, as crew replacement periods are not required. The estimated economic margin indicates that the next-generation autonomous ships can adopt greener technologies, such as hydrogen or green ammonia, to achieve the targeted carbon emissions reduction
