Citizen sensing applications need to have a number of users defined that ensures their effectiveness. This is not a straightforward task because neither the relationship between the size of the userbase or its effectiveness is easily quantified, nor is it clear which threshold for the number of users would make the application ‘effective’. This paper presents an approach for estimating the number of users needed for location-based crowdsourcing applications to work successfully, depending on the use case, the circumstances, and the criteria of success. It circumvents various issues, ethical or practical, in performing real-world controlled experiments and tackles this challenge by developing an agent-based modelling and simulation framework. This framework is tested on a specific scenario, that of missing children and the search for them. The search is performed with the contribution of citizens being made aware of the disappearance through a mobile application. The result produces an easily reconfigurable testbed for the effectiveness of citizen sensing mobile applications, allowing the study of the marginal utility of new users of the application. The resulting framework aims to be the digital twin of a real urban scenario, and it has been designed to be easily adapted and support decisions on the feasibility, evaluation, and targeting of the deployment of spatial crowdsourcing applications.

In alignment with the European Union’s legislation, Greece submitted its final 10-year National Energy and Climate Plan (NECP) in December 2019, setting more ambitious energy and climate targets than those originally proposed in the draft version of the document. Apart from higher penetration of renewable energy sources (RES), the final NECP projects also zero carbon use in power generation till 2030. Although decarbonization has long been regarded beneficial for economies that base their energy production on coal, as it is the case with Greece, the macroeconomic and societal ramifications of faster transitions to carbon-free economies remain highly unexplored. Under this context, in this paper, we soft-link energy models, namely Times-Greece and Primes, with a macroeconomic model, namely Global Trade Analysis Project (GTAP), to measure the effects of the final and draft NECPs on the Greek economy and evaluate the impact of higher decarbonization speeds. We find that the faster transition scenario displays both economic and societal merits, increasing Gross Domestic Product (GDP) and household income by about 1% and 7%, respectively.

This study introduces a framework for assessing the resilience of different European countries against the problem of energy poverty. The proposed framework is established upon two major implementation pillars: capturing stakeholder knowledge and employing a multi-criteria analysis framework in order to provide valuable insights and objective results. The implicated evaluation criteria have been identified by the group of stakeholders and incorporate several socio-economic aspects of the problem beyond the energy dimension. The proposed methodology is largely dependent on the engaged stakeholders’ assessments, thus introducing nuggets of subjectivity into the whole analysis. However, it significantly differs from other energy poverty-based approaches, its novelty lying in that it directly attempts to evaluate a country according to its potential to deal with the problem as a whole, rather than deconstructing it in components and partial indicators. The proposed framework is demonstrated in countries in both Southern/Eastern and Northern/Western Europe (Austria, Belgium, Croatia, France, Greece, Ireland, Italy, Latvia, the Netherlands, Romania, Spain), exploiting diversities and particularities associated with their context.

The European Union (EU) aims to prepare its strategy and infrastructure for further decarbonisation of its energy system in the longer term towards 2050. Recent political discussions and research interest focus on ways to accelerate the development and deployment of low-carbon technologies with respect to the targets set for 2030 and 2050. However, the diverse options available that are to be implemented, are policy sensitive and need careful comparative assessment. This paper presents a multi-criteria approach based on an extension of the Preference Ranking Organization METHod for Enrichment of Evaluations (PROMETHEE) method for group decision-making that incorporates fuzzy set theory in order to evaluate alternative transformation pathways for achieving a sustainable energy system in EU. This assessment aims at providing a direction towards a most preferable pathway concept that should be taken into account by a future model-based analysis of the necessary transformation of our energy sector. The results obtained could support policymakers in drawing effective recommendations based on the findings. The added value of this analysis to policymakers is its contribution to plan climate and energy strategies towards a low-carbon transition pathway by using the information of this approach and prioritizing uncertainties through an environmental and energy perspective.

Electricity demand forecasting is an essential process in the operation and planning procedures of power systems that considerably influences the decisions of utility providers. Main aim of this paper is, first, to examine the relationship between a time series and influential multiple criteria, and, second, to provide long-term electricity demand forecasts in Greece. An original disaggregation or ordinal regression analysis methodological framework is outlined to optimally assess a robust additive value model which is as consistent as possible with a given time series. The accuracy and stability of this modeling approach is guaranteed through the calculation of statistical error measures and robustness analysis indices, respectively. For the case of Greece, the additive value forecasting model is inferred from data related to the training period 1999–2013. The proposed method has been applied for the forecasting of the annual total net electricity demand in the Greek interconnected power system during the following testing period 2014–2016. The model implies that the level of economic growth, represented by the national gross domestic product, imposes the greatest influence on the electricity demand followed by the energy efficiency progress and the weather conditions in the country. The ordinal regression models perform considerably better than the multiple linear (least-squares) regression model, in terms of prediction reliability, resulting into a minimum MAPE equal to 0.74%. The exact method has been also applied for the extraction of electricity demand projections till 2027 based on alternative economic growth scenarios, indicating a constant increase of the electricity demand in Greece.

Energy policy making is a complex, multidisciplinary process that usually requires the assessment of a large number of factors. Consequently, Multiple Criteria Decision Making, which is a sub-discipline of Operational Research, has long been employed as an approach to addressing problems of this domain. This paper aims to explore how the preference disaggregation-aggregation paradigm, which infers a preference model from given global preferences on a set of reference alternatives, can support decision making in energy policy design and implementation. In this direction, a detailed literature review of multicriteria analysis applications in this domain is conducted, in which a knowledge gap regarding preference disaggregation approaches can be observed. The UTASTAR model is, then, described in detail and implemented in an energy policy application regarding the potential development of clean electricity projects through the cooperation between European Union member states and 22 neighbouring countries with which the Union has already established ties towards economic and energy market integration. The results of the study show that European countries outside the Union feature better potential for hosting clean energy projects compared to Middle East and North African countries; finally, the analysis suggests that UTASTAR can also provide concrete insight into the criteria weighting dynamics, as inferred by the global preferences of the decision makers.

A key factor hampering the delivery of high energy performance renovations in buildings is the under-qualification of the construction sector's workforce with regard to energy efficiency and renewable energy sources systems. Towards this direction, this paper proposes an integrated methodological framework, determining measures for the case of Greece, which are delivered in the form of a national qualification roadmap. These measures aim to enhance the qualifications of the blue collar workers and generally empower the Greek construction sector. They also facilitate the adherence of Greece to the European Energy Efficiency and Renewable Energy Sources Directives and support the attainment of the national energy objectives for 2020. The methodological framework is initiated with the analysis of the status quo of the Greek building sector and the skills and qualifications gap of the workforce, as well as the identification of the corresponding barriers that impede growth. Subsequently, a number of diverse measures are proposed and evaluated, using a synergy of decision analysis and evaluation methods. The measures that are assessed as of high priority are afterwards specified to concrete actions. Throughout the whole modular procedure, multiple relevant national bodies were actively engaged via transparent consultation procedures and multilateral discussions. Finally, 44 acknowledged organisations declared their endorsement to the roadmap by signing an official letter.

The national binding targets, set for renewable energy deployment at European Union (EU), call for extended clean energy investments. Renewable energy projects require high up-front expenditures including, in many cases, considerable financing costs. The main objective of this paper is to elaborate and apply a methodology that allows assessing the most important risk categories related to renewable energy investments. The cornerstone of this approach is the weighted average cost of capital, which has been extracted for new onshore wind projects in EU-28 member states based on diverse methods e.g. Capital Asset Pricing Model. Moreover, to validate the model results, a series of interviews with renewable energy project developers and financers across the EU has been conducted. The results show that, following the country risk, policy-related risks exert the highest impact on the cost of capital. Moreover, there are significant discrepancies between different geographical regions and market deployment levels. To support policy makers' decision on effective risk-reducing policy designs, the assessment could also be extended to other renewable energy technologies.

Surveys have revealed that the cost to the economy caused by the occurrence of power interruptions is significant. Distribution transformers constitute the most important technical component of an electrical distribution network. The purpose of this paper is to assess the cost to the Greek economy, deriving from failures of distribution transformers due to induced overvoltages and thefts. The effects stemming from distribution transformer failures to the economy are investigated in the following three sectors: service (tourism, banks, commerce, private and public services), residential and agricultural sector. The above issue and underlying policy matters are of vital importance, especially in the case of the periphery’s highly indebted countries. Finally, a computational model is introduced in order to quantify the relative cost and analytical results are illustrated and discussed.

During the last years, the manufacturing industry is experiencing an increasing trend in the utilization of mixed-model assembly lines (MMALs). These lines, often adhering to the Just-In-Time production system, produce diversified products efficiently, maintaining least possible inventories. In this paper, the sequencing of an already balanced large scale double MMAL, manufacturing cars, is modeled as an integer mathematical programming problem and optimized over four objective functions. Two classical multiobjective methods are implemented to solve the mathematical integer programming problem, as well as a synergy of them. The former two are: the compensatory one, global criterion method, and the non-compensatory one, method of satisfactory goals, proposed by Benson. In addition, the model is solved using a combination of the aforementioned methods, as proposed by the authors, which is coupling certain characteristics from both. All three methods make use of the preferences, extracted from a real decision maker, responsible for the management of the production, who is enabled to choose the most preferred among the optimal solutions. Finally, the results, obtained from the implementation of the three separate methods, are assessed with regard to their effectiveness and efficiency.

This paper introduces an innovative approach for more factual, evidence-based and accountable policy analysis and evaluation, based on open public data, prosperity indicators, fuzzy cognitive maps and argumentation technology. The approach is inspired by the Policy Compass FP7 project and assumes to make better use of Europe's open public data resources, so as to enable both the lay public and domain experts to create, apply, annotate, share and discuss progress metrics and causal models of policies. The aim is to empower stakeholders in assessing the governments' course of actions and contribute in transforming government structures to a more participatory and democratic form. The paper attempts to make a rather complete and comprehensive statement for policy analysis and evaluation, as it provides a thorough description of the proposed approach, including both its theoretical framework and technical approach, as well as a series of indicative use case scenarios and anticipated benefits. The paper concludes with relevant implementation concerns as well as future plans for the validation of the approach and its benefits.

Although the Covenant of Mayors (CoM) initiative embraces all regions and is not intended solely for large cities, fewer regions with rural characteristics have adhered to this initiative. In this respect, particular emphasis has to be laid on them towards 'greening' rural communities economies. The main aim of this paper is to present an interactive supportive framework realised into web application, thus consisting a tool for the elaboration of rural communities' sustainable energy action plan (SEAP). The web tool provides the necessary support to the user, in order to significantly reduce the required elaboration time for the SEAP's development.

In this paper we develop an interactive decision analysis approach to treat a large scale bicriterion integer programming problem, addressing a real world assembly line scheduling problem of a manufacturing company. This company receives periodically a set of orders for the production of specific items (jobs) through a number of specialised production (assembly) lines. The paper presents a non compensatory approach based on an interactive implementation of the ε-constraint method that enables the decision maker to achieve a satisfactory goal for each objective separately. In fact, the method generates and evaluates a large number of non dominated solutions that constitute a representative sample of the criteria ranges. The experience with a specific numerical example shows the efficiency and usefulness of the proposed model in solving large scale bicriterion industrial integer programming problems, highlighting at the same time the modelling limitations.

In a turbulent world where technological evolution has surpassed even the most imaginative scenarios predicted a few years ago, interoperability remains an intangible and elusive challenge. Associated with cost, risk and complexity reduction, Enterprise Interoperability can be defined as a capability of two or more enterprises, including all the systems within their boundaries and the external systems that they utilize or are affected by, to cooperate seamlessly, over a sustained period of time to pursue a common objective. During the last decade, substantial advancements at an application level have been made through EU- and national funded research. However, the lack of scientific foundations seems to hinder unlocking its full potential. In this context, the aim of this paper is to investigate the pathway towards establishing a science base and to provide an overview of the main milestones in the fascinating quest that shall eventually shape interoperability as a scientific discipline.
