Abstract

Purpose

The purpose of this paper is to present the Business Strategy Assessment Model (BSAM) approach, in an attempt to explore the principle dynamics of an energy‐economic system with emphasis on the private actors' point of view and the impact different policy instruments may have on the decisions of private actors with different characteristics.

Design/methodology/approach

In the BSAM model, investment decisions under consideration depend on their perceived financial value. Basis for the financial valuation of an investment option is formed by simulating market dynamics with alternative price scenarios. The outputs include: investment strategies, derived as a function of the (uncertain) state vector of future market conditions and risk premium, calculated by contrasting the expected net present value for the optimal timing of the investment and the expected net present value of an immediate investment generation module of the BSAM, while both of these outputs are estimated for each available technology option.

Findings

Different models make different assumptions shedding light upon different aspects of the socio‐economic systems they attempt to analyze and hitherto, no such model succeeds in incorporating all the perceptions that are driving the integration of energy policies. BSAM is based on the notion that a convergence between policy evaluation and business strategy assessment models could be truly beneficial for regulators that aim to derive effective energy policies. Both the algorithm adopted and the structure of the modules of BSAM facilitate the analysis of complex interactions in a firm's decision making process, and even more the what‐if analyses needed for alternative policy measure evaluation.

Originality/value

Setting the framework for a modelling approach that incorporates the role of risk‐return perceptions of private actor's with diverse features, portfolio effects, path dependence and agent competition, into appraising energy and climate policies, and suggest that the heterogeneous world of investors requires reflexive assessment techniques. Above and beyond, understanding the drivers and triggers of firm's investment strategies will allow improving the effectiveness of energy policies.

Abstract

Purpose

The purpose of this paper is to identify the most appropriate multidisciplinary data sources related with energy optimization decision support as well as the related methodologies, tools and techniques for data capturing and processing for each of them.

Design/methodology/approach

A review is conducted on the state-of-play of decision support systems for energy optimization, focussing on the municipal sector, followed by an identification of the most appropriate multidisciplinary data sources related with energy optimization decision support. An innovative methodology is outlined to integrate semantically modeled data from multiple sources, to assist city authorities in energy management.

Findings

City authorities need to lead relevant actions toward energy-efficient neighborhoods. Although there are more and more energy and other related data available at the city level, there are no established methods and tools integrating and analyzing them in a smart way, with the purpose to support the decision-making process on energy use optimization.

Originality/value

A novel multidimensional approach is proposed, using semantic technologies to integrate data from multiple sources, to assist city authorities to produce short-term energy plans in an integrated, transparent and comprehensive way.

Abstract

Purpose

The unmanned ground vehicle (UGV) described in this manuscript is a robot designed by the authors to map the underground mine environments. The UGV works to develop a computational intelligence-based cyber-physical system (CPS)-based analytical framework for mining operations. The UGV demonstrated excellent semi-autonomous navigation capabilities in the absence of GNSS signals. The UGV has a suite that works in unison to provide relevant information. These sensors are integrated to form a robust sensor fusion-based architecture, creating a CPS with a wide range of capabilities such as data acquisition and navigation in challenging underground environments. UGVs can be used to enhance the efficacy of safety inspections, rescue during underground emergencies and assist miners in hazardous conditions.

Design/methodology/approach

In this research, an UGV was constructed whose operations are enabled by sensors including a D415i Red Blue Green (RGB) depth camera, a LiDAR, a FLIR C5 infrared camera and smart air quality sensors. This sensor fusion-based architecture forms a CPS. Data obtained remotely are processed by deep learning algorithms to achieve overall capabilities such as real-time image analysis for miner identification, object detection, posture analysis and identifying threats of roof falls and overhangs. Simultaneous localization and mapping (SLAM) algorithms create a 3D map, facilitate autonomous navigation and build a decision support system for delivering mine rescue support.

Findings

The aim of this study is to include this capacity in training situations when it has been validated and authorized by the Directorate General of Mines Safety (DGMS) Indian government regulatory agency for safety in mines and oil fields. The longwall demo mine, at IIT (ISM) is being used as the site of the first operations. Once approved by the respective enforcement agencies, this technology and the accompanying rescue and training process can be used in underground operations.

Originality/value

In fact, this paper is the first attempt at remotely operated UGVs based on CPSs, the CPS–UGV in Indian mine conditions, so as to revolutionize Indian mines based on the idea of Industry 4.0.

Abstract

Purpose

The purpose of this paper is to examine the electronic identity (eID) market from a social, technical and regulatory viewpoint, and the opportunities/challenges for policymakers. The paper also aims to discuss whether a single European market for identity is realistic and whether a common eID framework for Europe is timely and appropriate.

Design/methodology/approach

The paper presents a structured review of user behaviours, a timeline of technical developments, and an analysis of market trends and policy analysis in relation to the eID ecosystem.

Findings

Users of electronic systems and applications disclose increasingly more identity‐relevant data. These data are often a prerequisite to the supply of advanced electronic services. In economic terms, the utility functions of users and service providers in relation to eID data are divergent. This generates a market asymmetry, as service providers are able to extract value from user data via opaque value propositions. European policymakers have different options to redress this unbalance. An eID framework based on the “privacy by design” approach is seen to offer a solution to excessive disclosure, market fragmentation and unclear value propositions. The strengths and weaknesses of the approach are assessed.

Research limitations/implications

Results from the application layer of the eID market are based on exploratory research. Evidence from a larger number of cases and sectors is required to determine and articulate emerging value chains.

Practical implications

In discussing an eID framework, policymakers should address critical issues concerning resources and funding, balance between online versus offline transactions and between present versus future technologies, users' actual behaviours, the infrastructure of certification and trust, and governance at the industrial, member state and EU levels.

Originality/value

The paper draws together research in four domains – social, technical, market and regulatory. It addresses for the first time the barriers to the “privacy by design approach”, alongside its virtues.

Abstract

Purpose

The purpose of this paper is to reveal the dynamics of the Greek energy sector. As energy sectors contribute substantially to a national economy and stimulate national output and employment, it is important to identify their upward and downward linkages and interrelations with the other sectors of the economy.

Design/methodology/approach

To do this and capture such relations in the economy, a general equilibrium model is used. In specific, input–output (I–O) analysis is used and a model is specifically built for the Greek economy to examine in detail the energy sectors. Multiplier and linkage analysis is performed to assess their dynamics in terms of output, household income and employment.

Findings

Results indicate that the three energy sectors’ multipliers and elasticities, though are not ranking in the first places, are enough high indicating their strong linkages in the economy and their potentials to enhance the economy’s total output, employment and household income.

Research limitations/implications

Further disaggregation of the economy’s energy sectors is needed to make clearer the separation among renewable and non-renewable sector, to identify and compare the dynamics and contribution of each category in the economy. Additionally, an environmental I–O model would indicate consequences on the environment and not just pure economic benefits.

Practical implications

Through the analysis, it can be seen that energy sectors and secondary energy products have the ability to drive a country’s economic activity through exports and intersectoral linkages, even if it is not a crude petroleum producing economy. Thus, knowledge of the economic impacts of such sectors is a valuable information.

Originality/value

The current study provides significant information of an economy’s energy sectors regarding their ability to support economic activity and employment. A general equilibrium model is used, examining the whole economy, to assess direct and indirect interrelationships.

Abstract

Purpose

The purpose of this paper is to assess the potential of renewable energy as an essential future energy source in the Gulf Cooperation Council (GCC) region. This paper summarizes the main projects and measures established to start the transition toward renewable energy. The opportunities and challenges for developing renewable energy projects have been discussed to reach a better understanding of the future of renewable energy in the region.

Design/methodology/approach

The paper provides a literature-based study on the status of the renewable energy sector in the GCC, including potentials, projects, targets and strategies. The opportunities and challenges of the development of renewable energy sources in the GCC region have been discussed based on the literature.

Findings

The paper shows that the GCC countries have begun to adopt a more proactive approach toward renewable energy, while the reorientation of strategies and plans for renewable energy is evolving in these countries. All of the GCC countries focus on solar and wind energies and plan to invest in waste-to-energy (WtE), while only Saudi Arabia is interested in going for geothermal.

Originality/value

The paper contributes to the provision of an extensive literature review on the development of renewable energy in the GCC countries. It provides an updated and comprehensive overview of the region’s renewable energy potential and highlights the main renewable energy strategies and targets. This paper targets regional decision-makers as well as multilateral stakeholders to formulate a set of recommendations to promote renewable energy deployment and improve industrial capabilities.
