    Since the beginning of the aviation industry, fossil fuel is being used as the only source of fuel to power airplanes. Each year the popularity of aviation industry among the passengers is increasing dramatically because of its short journey time. Therefore, the demand of fossil fuel is also increasing to support the additional need. However, the stock of fossil fuel is reducing and will all be consumed within a couple of decades. In addition to this, the increment of greenhouse gas has become another issue, which should be dealt with urgently in order to not contribute to global warming. Because of these upcoming problems, another source of fuel and a significant development in aircraft design are a must for the future of aviation industry. Some new sources of fuels are being tested as alternative fuels. Solar power, biofuels, and hydrogen fuel are some of them. New techniques for aircraft design have also been developed within the last couple of years. To make these new ideas available, all the aircraft manufacturing companies and engineers should work collectively

    A fuzzy multi-criteria decision making approach for analyzing the risks and benefits of opening data

    Governments are releasing their data to the public to accomplish benefits like the creation of transparency, accountability, citizen engagement and to enable business innovation. At the same time, decision-makers are reluctant to open their data due to some potential risks like misuse, sensitivity, ownership, and inaccuracy of the data. The goal of the study presented in this paper is to develop a Fuzzy Multi-Criteria Decision Making (FMCDM) approach to analyze the risks and benefits to determine the decision to open a dataset. FMCDM is chosen due to its capability to measure and weight the relative importance of the criteria. FMCDM need the weighting of criteria as input. For this Fuzzy Analytical Hierarchy Process (FAHP) is utilized by collecting input from experts’ knowledge and expertise. The scores for each criterion are summed up to rank the importance of the alternatives. Four main criteria are used, e.g. data sensitivity and data ownership representing risks criteria, and data availability and data trustworthy as benefits criteria. For each criterion, there were two sub-criteria identified. Four types of decisions to open data can be made: completely open, maintain suppression, provide limited access, and remain closed. A health patient record dataset is used to illustrate the approach. In further research, we recommend to develop automated approaches that take a dataset as an input and can provide an advice.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Information and Communication Technolog
