Energy efficiency in discrete-manufacturing systems: insights, trends, and control strategies

Since the depletion of fossil energy sources, rising energy prices, and governmental regulation restrictions, the current manufacturing industry is shifting towards more efficient and sustainable systems. This transformation has promoted the identification of energy saving opportunities and the development of new technologies and strategies oriented to improve the energy efficiency of such systems. This paper outlines and discusses most of the research reported during the last decade regarding energy efficiency in manufacturing systems, the current technologies and strategies to improve that efficiency, identifying and remarking those related to the design of management/control strategies. Based on this fact, this paper aims to provide a review of strategies for reducing energy consumption and optimizing the use of resources within a plant into the context of discrete manufacturing. The review performed concerning the current context of manufacturing systems, control systems implemented, and their transformation towards Industry 4.0 might be useful in both the academic and industrial dimension to identify trends and critical points and suggest further research lines.Peer ReviewedPreprin

Methodology for Designing Decision Support Systems for Visualising and Mitigating Supply Chain Cyber Risk from IoT Technologies

This paper proposes a methodology for designing decision support systems for visualising and mitigating the Internet of Things cyber risks. Digital technologies present new cyber risk in the supply chain which are often not visible to companies participating in the supply chains. This study investigates how the Internet of Things cyber risks can be visualised and mitigated in the process of designing business and supply chain strategies. The emerging DSS methodology present new findings on how digital technologies affect business and supply chain systems. Through epistemological analysis, the article derives with a decision support system for visualising supply chain cyber risk from Internet of Things digital technologies. Such methods do not exist at present and this represents the first attempt to devise a decision support system that would enable practitioners to develop a step by step process for visualising, assessing and mitigating the emerging cyber risk from IoT technologies on shared infrastructure in legacy supply chain systems

A Review of State-of-the-Art Large Sized Foam Cutting Rapid Prototyping and Manufacturing Technologies.

Purpose – Current additive rapid prototyping (RP) technologies fail to efficiently produce objects greater than 0.5?m3 due to restrictions in build size, build time and cost. A need exists to develop RP and manufacturing technologies capable of producing large objects in a rapid manner directly from computer-aided design data. Foam cutting RP is a relatively new technology capable of producing large complex objects using inexpensive materials. The purpose of this paper is to describe nine such technologies that have been developed or are currently being developed at institutions around the world. The relative merits of each system are discussed. Recommendations are given with the aim of enhancing the performance of existing and future foam cutting RP systems. Design/methodology/approach – The review is based on an extensive literature review covering academic publications, company documents and web site information. Findings – The paper provides insights into the different machine configurations and cutting strategies. The most successful machines and cutting strategies are identified. Research limitations/implications – Most of the foam cutting RP systems described have not been developed to the commercial level, thus a benchmark study directly comparing the nine systems was not possible. Originality/value – This paper provides the first overview of foam cutting RP technology, a field which is over a decade old. The information contained in this paper will help improve future developments in foam cutting RP systems

Design Improvements from users’ experiences of low and zero carbon technologies

The development and rapid consumer adoption of low and zero carbon (LZC) technologies are key elements of UK and EU carbon reduction strategies to meet the challenge of climate change. Many LZC technologies are available, ranging from established energy efficiency products such as home insulation and energy-efficient lighting to more innovative renewable energy technologies, including solar thermal systems, micro-wind turbines, solar photovoltaics and biomass stoves. This paper examines key influences on consumer adoption – and non-adoption – of energy efficiency products and renewable energy systems based on the findings of a UK Open University project, which conducted some 111 in-depth telephone interviews plus an on-line survey with nearly 400 responses. The results show that it is important to research consumer requirements and use behaviours when developing ‘green’ technologies. Consumer adoption of LZC products and systems has been relatively slow and, even when installed, due to behavioural effects, they have not always reduced carbon emissions as much as expected. The results of this study of UK consumers’ experiences shows that improved designs are required to address barriers to LZC adoption and problems in use, including functionality, ergonomics, interconnectedness with other systems and symbolic value, as well as price and payback. Offering challenges for designers, engineers and managers, the paper identifies user-centred improvements to promote more rapid adoption and effective use of LZC technologies

Methodological Approaches to Modeling Information Architecture of the Organization in the Conditions of Digital Economy

It is significant for businesses, especially in the digital economy, the solution of theoretical and methodological justifications and the development of practical recommendations for building an organization\u27s information architecture as a holistic description of its key strategies, related to business, information, application systems and technologies, and also their impact on the functions and business processes of an organization. The article discusses issues, related to methodological approaches to modeling an organization\u27s information architectureб using information management tools to help manage innovation in information systems (IS) and information technologies (IT). The relevance of organizational provisions to determine the way, in which a business entity\u27s business model is functionally integrated with the IS architecture is substantiated. The consideration and analysis of the use of industrial standards for describing the architecture of an organization, adopted by such institutions as the International Organization for Standardization (ISO), The Open Group, Institute of Electrical and Electronics Engineers (IEEE), etc. reveal that none of these standards is dominant and does not provide teams, responsible for the architecture development with all the tools, necessary from the methodological point of view and from the point of view of the templates, used to describe the architecture. Recommendations are given on the theoretical and methodological substantiation and construction of the information architecture of an organization as a complete description of its key strategies related to business, information, application systems and technologies, as well as their impact on the functions and business processes of an organization

Designing low and zero carbon products and systems: improvements based on consumers’ experience of adoption and use

The development and rapid consumer adoption of low and zero carbon (LZC) technologies are key elements of UK and EU carbon reduction strategies to meet the challenge of climate change. Many LZC technologies are available, ranging from established energy efficiency products such as home insulation and energy-efficient lighting to more innovative renewable energy systems, including solar thermal systems, micro-wind turbines, solar photovoltaics and biomass stoves and boilers. This paper examines key influences on consumer adoption – and non-adoption – of energy efficiency products and renewable energy systems based on the findings of a UK Open University project, which conducted some 90 in-depth telephone interviews plus an on-line survey with nearly 400 responses during 2006. The survey results show that it is important to research consumer requirements and use behaviours when developing ‘green’ technologies. Consumer adoption of LZC products and systems has been relatively slow and, even when installed, due to behavioural effects, they have not always reduced carbon emissions as much as expected. The results of this study of UK consumers’ experiences shows that improved designs are required to address barriers to LZC adoption and problems in use, including functionality, ergonomics, interconnectedness with other systems and symbolic value, as well as cost and payback. Offering challenges for designers and engineers and marketers, the paper identifies user-centred ideas and concepts to promote more rapid adoption and carbon-saving use of LZC technologies

Strengthening education, extension and training to accelerate climate resilience and low carbon development in the agriculture sector

The dynamic nature of climate and its impacts on agriculture is rendering most of the existing adaptation and coping strategies unsupportive in many regions. Recent studies on economic sectors (including agriculture) across institutions and 24 counties have established the following: a widened gap between skills possessed by youth and those required by the job market; inadequate technical skills and knowledge on climate change and climate-smart technologies by the extension service providers; climate change has not been adequately integrated into Kenya’s formal agricultural education, extension and training systems such as the Kenya School of Agriculture (KSA), Agricultural Technology Development Centres (ATDCs), Agricultural Training Centres (ATCs) and Agriculture Technical Vocational Education and Training (ATVET); the existing policies and strategies for capacity building for the agriculture sector have limited provisions for promoting climate resilient and low carbon development solutions. These calls for integration of climate change into the formal education, extension and training systems; equipping the training institutions to facilitate adoption of climate-smart innovations; capacity building of the extension service providers to enhance utilization and adaptation of the appropriate support agricultural technologies, innovations and climate-smart farming practices

Collaboration Enabling Internet Resource Collection-Building Software and Technologies

Over the last decade the Library of the University of California, Riverside and its collaborators have developed a number of systems, service designs, and projects that utilize innovative technologies to foster better Internet finding tools in libraries and more cooperative and efficient effort in Internet link and metadata collection building. The open-source software and projects discussed represent appropriate technologies and sustainable strategies that we believe will help Internet portals, digital libraries, virtual libraries, library catalogs-with-portal-like-capabilities (IPDVLCs), and related collection-building efforts in academia to better scale and more accurately anticipate and meet the needs of scholarly and educational users.published or submitted for publicatio
