A method is presented for selecting a preferred ship from a group of candidates as a reference ship for a new design. The
method is based on a recently developed approach for multiple-criteria decision analysis under uncertainty, the evidential
reasoning approach. Using this method, both quantitative and qualitative attributes of a complicated nature can be considered
in the selection process. The method consists of three phases: identifying suitable candidate ships, evaluating them in terms
of both conventional techno-economical and qualitative attributes, and aggregating all the attributes using the evidential
reasoning approach. This three-phase procedure is illustrated by means of an oil tanker selection example. The results of
this study show that the evidential reasoning approach can support multiple-criteria ship selection processes when both qualitative
and quantitative information with or without uncertainties have to be taken into account. The outcomes generated by the method
include the ranking of the candidate ships and indications of their strengths and weaknesses in the format of performance
distributions over different assessment grades. Such information is vital in helping decision makers to make an informed selection
and be aware of any risk implication associated with the selection. 相似文献

The application of social marginal cost pricing (SMCP) in PPP's in the railway sector faces several challenges. We examine in detail the practical applicability of SMCP in railway PPPs from the perspectives of cost accounting and effectiveness of SMCP towards the allocative efficiency goal, addressing the likely drawbacks in conciliating the welfare objectives of SMCP with the objectives of project financing (cost recovery) and value for money that justify the realization of PPP's. To this end, we combine theoretical analysis with the observation of empirical results of a case study. We split the analysis per type of private service provision, which can be for service operation or infrastructure management. For infrastructure management, we recommend splitting the operator remuneration and the track access charges. For service operation, we argue that the correct decision on source of funding of the service operator should depend on the characteristics of the contract. 相似文献

Most global trade statistics in the public domain refer to official customs data, which are not generally available on a micro (individual cargo) level. With the increasing availability and completeness of ship positioning data from the global Automated Identification System (AIS), it is possible to derive more timely and detailed trade statistics for homogeneous commodity groups. The objective of this article is twofold: (1) to compare the accuracy of AIS-derived trade statistics to official customs data in the crude oil market and (2) to add a breakdown of trade by vessel size over time. We find that while AIS-derived data for seaborne crude exports show good alignment with official export numbers in aggregate, there are substantial temporal and geographical differences across countries and time due to the use of pipelines and transshipment in parts of the supply chain. We highlight the challenges in properly structuring and aggregating micro-level cargo data. Our findings are important for the proper derivation of shipping demand from trade data. 相似文献
