Factors Influencing the Economic Feasibility of Unmanned Ships

The research effort into unmanned and autonomous ships has increased significantly over the last decade. Although not all required technology is currently commercially available, consensus is that from a technical standpoint, unmanned shipping is possible. The next question is: is it economically feasible to operate an unmanned ship. The...

Implementation of eco-efficient procedures to mitigate the climate impact of non-CO2 effects

Within this study, the lack of incentivizing airlines to internalize their climate costs is tried to be closed by the introduction of climate-charged airspaces, as non-CO2 emissions have locationand time-dependent effects upon the climate. In order to create an incentive for airlines to minimize flight time and emissions in highly...

Societal costs and benefits of high-value open government data: a case study in the Netherlands

Much research has emphasised the benefits of open government data, and especially high-value data. The G8 Open Data Charter defines high-value data as data that improve democracy and encourage the innovative reuse of the particular data. Thus, governments worldwide invest resources to identify potential high-value datasets and to publish these...

Cost-Benefit Assessment of Climate and Weather Optimized Trajectories for Different North Atlantic Weather Patterns

Besides CO2, the climate impact of commercial aviation is strongly influenced by non-CO2 effects, which are highly sensitive to meteorological conditions and their spatial variations. To assess the cost-benefit potential (climate impact mitigation vs. cost increase) of climate and weather optimized flight trajectories in the North Atlantic...

Multi-level repair decision-making process for composite structures

This paper details the development of a decision-making model that evaluates the multiple repair levels that a composite structure can undergo, each with its inherent achievable survivability and consequence to operations in terms of availability, costs, and scheduling. The goal of this model is to provide the maintainer an integrated approach...

A Framework for Risk Assessment of Groundwater Drawdown Induced Subsidence

Sub-surface constructions generally involve drainage of groundwater, which can induce land subsidence in compressible soil deposits and cause extensive damage costs in urban areas. A probabilistic framework, in accordance with the risk management framework outlined by the International Standard Organization (ISO), for assessing risks of...

Economic implications of multi-layer safety projects for flood protection

Recent experience of large-scale water disasters such as Hurricane Katrina in 2005 and the Great Eastern Japan Earthquake and Tsunami in 2011 has reminded mankind that disasters cannot be ruledout. Unprecedented low-probability events can happen even in the most well monitored areas, causing major social-economic disruption. Failing to prepare...

Quantifying benefits of enhanced service reliability in public transport

An Analysis of the Necessity for 3D Cadastres with Reference to Trinidad and Tobago

The theoretical methodology for the construction of a 3D cadastre can be an interesting academic exercise that is worthy of investigation. For individual countries or jurisdictions, however, the practical possibility of implementation must be supported by a discussion of the situational need and a cost-benefit analysis of the concept. This...

Current issues in the Dutch CBA practice

In the Netherlands a guideline for carrying out a CBA for infrastructure projects (the so-called OEI-manual) was constructed in the year 2000. Since then a CBA in line with the OEI-manual became compulsory in the decision making process for all large infrastructure national projects. The aim of this research is to define the main problems in the...
