Shipping companies are high-vulnerability information handling organizations (HIHOs). In the past, such companies used exclusively HIHO private communication networks and own satellite resources in order to share and transport sensitive information. In recent years, the ability for the HIHO network users to exploit the advantages of the low-vulnerability information handling organizations' (LIHOs) value added networks, has led to the need for augmentation of the HIHO networks. In the maritime sector, a push-and-pull effect on the need and demand to transfer information onboard and ashore has led many companies to experiment with interconnected HIHO and LIHO open distributed systems and networks, for their ship-to-shore communications. Security then becomes an issue in a domain, onboard-ashore data transmissions, where little information on the level of risk is available. This paper proposes a risk assessment and management framework to assist in countermeasure selection and level of LIHO network use definition. The model is ultimately applicable where information on potential risks and their impact is minimum and simultaneously changeable. The model is connected to a security profile for interconnected HIHO and LIHO open distributed systems and networks. 相似文献

Environmental sustainability in the port industry is of growing concern for port authorities, policy makers, port users and local communities. Innovation can provide a solution to the main environmental issues, but often meets resistance. While certain types of technological or organisational innovation can be satisfactorily analysed using closed system theories, in the case of seaports and in particular in the area of environmental sustainability, more advanced conceptual frameworks have to be considered. These frameworks need to be able to account for the multiple stakeholder nature of the port industry and of the network and vertical interactions that environmental sustainability calls for. This article investigates successful innovations improving environmental sustainability of seaports. The proposed framework builds in part on research concepts developed in the InnoSuTra EU FP7 project. From a methodological perspective, this article develops a method for quantifying the degree of success of innovation with respect to a set of specific objectives. Several case studies are used to test the framework against real innovation examples, such as onshore power supply, or alternative fuels. In this article, we argue that only those innovations that fit dynamically port actors’ demands and the port institutional environment stand a chance to succeed. 相似文献

AbstractTransport infrastructure public private partnership (PPP) projects are very diverse and complex in nature not only because of their mode-specific intricacies but also because of their inherent economic characteristics that relate to the scope of involvement of the private sector in the project, the large sunk costs incurred, and ultimately, the competition to which these projects are exposed. The allocation of revenue risk is of paramount importance for the successful implementation of such projects and a sub-optimal allocation may lead to project structuring that is unnecessarily expensive and vulnerable to failure. At the same time, the revenue risk depends critically on the remuneration model used (user-based versus budget-based) and may, in turn, take the form of demand risk, counterparty risk or combinations of the two. This review explores the issues related to revenue risk allocation for transport infrastructure PPP projects. Overarching principles for the allocation of revenue risk that transcend mode-specificity are identified and compared to case studies generated in the context of the COST Action TU1001. The results show that theory and practice are divergent, leading to sub-optimal structuring and exposing projects to potential failure. 相似文献

The main objective of this paper is ‘to assess the conditions, including policy support, under which innovative concepts have a high chance of getting adopted and being successful’. The work will start from the state-of-the-art with the following goals targeted. Firstly, to identify the paths that new innovative concepts usually follow, what key determinants are, which actors are involved, and what policy has been doing and can do. As part of this, a typology of variables is established, which will be the basis for the identification of successful adoption paths. Illustrations are provided of the performance of different innovative concepts in the seaport sector. A further goal is to propose policy recommendations, identify best practices, barriers to implementation and transferability of innovative concepts and processes. Finally, the research establishes developments needed in assessment methods and a methodological framework if innovative concepts are introduced. 相似文献

The maritime and port sector is widely considered conservative concerning the ability to introduce innovation in respect to other industries. This may be due to the lack of cooperative interactions among the several players involved. It does not mean that innovation does not occur in this industry. Along with some technical innovations, managerial, organizational, and cultural innovations also take place in the sector. The literature has considered the assessment and effects of the adoption of particular innovation, but still few studies underline the innovation path in a broad sense with a specific focus on terminal operators. The present article aims at filling this gap through a field analysis grouping together case studies developed in different world regions and examining the adoption path of innovation through a mix of three different techniques (i.e. the H- and I-indexes, a Systems of Innovation Analysis, and a Qualitative Comparative Analysis). Research outcomes underline how, even if no unique recipe for success can be found, specific factors (e.g. a ranking of innovation objectives, coordination among actors, and institutions) can influence the achievement of success. The analyses allow suggesting strategic and policy advice that may help link in a better way the innovation drivers with their actual effects. 相似文献
