AbstractA paradigm is an accepted world view. If we do not continually question our paradigm then wider trends and movements will overtake the discipline leaving it ill adapted to future challenges. This Special Issue is an opportunity to keep systems thinking at the forefront of ergonomics theory and practice. Systems thinking prompts us to ask whether ergonomics, as a discipline, has been too timid? Too preoccupied with the resolution of immediate problems with industrial-age methods when, approaching fast, are developments which could render these operating assumptions an irrelevance. Practical case studies are presented to show how abstract systems problems can be tackled head-on to deliver highly innovative and cost-effective insights. The strategic direction of the discipline foregrounds high-quality systems problems. These are something the discipline is well able to respond to provided that the appropriate operating paradigms are selected. Practitioner Summary: High-quality systems problems are the future of the discipline. How do we convert obtuse sounding systems concepts into practical interventions? In this paper, the essence of systems thinking is distilled and practical case studies used to demonstrate the benefits of this new paradigm. 相似文献

AbstractThe issues being tackled within ergonomics problem spaces are shifting. Although existing paradigms appear relevant for modern day systems, it is worth questioning whether our methods are. This paper asks whether the complexities of systems thinking, a currently ubiquitous ergonomics paradigm, are outpacing the capabilities of our methodological toolkit. This is achieved through examining the contemporary ergonomics problem space and the extent to which ergonomics methods can meet the challenges posed. Specifically, five key areas within the ergonomics paradigm of systems thinking are focused on: normal performance as a cause of accidents, accident prediction, system migration, systems concepts and ergonomics in design. The methods available for pursuing each line of inquiry are discussed, along with their ability to respond to key requirements. In doing so, a series of new methodological requirements and capabilities are identified. It is argued that further methodological development is required to provide researchers and practitioners with appropriate tools to explore both contemporary and future problems. Practitioner Summary: Ergonomics methods are the cornerstone of our discipline. This paper examines whether our current methodological toolkit is fit for purpose given the changing nature of ergonomics problems. The findings provide key research and practice requirements for methodological development. 相似文献

Abstract Ergonomics is not always used effectively by practising designers, and is still seen as limiting their creativity. Reasons for this include: ergonomics information is not presented in a readily assimilated form to designers during their design education and later design activities; design decisions relating to ergonomics issues are not addressed and discussed systematically by all members of the design team during concept design; the user centred approach that ergonomics encourages in design is not always included as part of the education of future designers. With computers being used more widely in design and design education, they could be used to deliver ergonomics information and help structure discussion of ergonomics issues amongst the design team from the earliest stages of design. This paper describes findings relating to the use of ergonomics in automotive design, and proposes two tools which could enhance the use of ergonomics in design education and in current and future design practice. 相似文献

Since its formal inception more than half a century ago, ergonomics has time and again demonstrated that it has a niche among the field of scientific disciplines aspiring to make the world a better place. How far has it really gone? Can we now lay claim that it is indeed well-known and accepted? Are the benefits it purports to deliver realized in all parts of the world? About two-thirds of human beings live in the Third World. This is where poverty and inequality are relatively more common. This is where much work is still degrading and far from being humane. This is also where ergonomics has yet to make its presence felt in practice. This paper attempts to show that ergonomics can and will become a globally applied science. However, it has to make its contribution to the Third World prevalent and long-lasting. The paper focuses on the current state of ergonomics in the Third World, the so-called Industrially Developing Countries (IDCs). 相似文献

Since 1958 more than 80 journal papers from the mainstream ergonomics literature have used either the words ‘complex’ or ‘complexity’ in their titles. Of those, more than 90% have been published in only the past 20 years. This observation communicates something interesting about the way in which contemporary ergonomics problems are being understood. The study of complexity itself derives from non-linear mathematics but many of its core concepts have found analogies in numerous non-mathematical domains. Set against this cross-disciplinary background, the current paper aims to provide a similar initial mapping to the field of ergonomics. In it, the ergonomics problem space, complexity metrics and powerful concepts such as emergence raise complexity to the status of an important contingency factor in achieving a match between ergonomics problems and ergonomics methods. The concept of relative predictive efficiency is used to illustrate how this match could be achieved in practice. What is clear overall is that a major source of, and solution to, complexity are the humans in systems. Understanding complexity on its own terms offers the potential to leverage disproportionate effects from ergonomics interventions and to tighten up the often loose usage of the term in the titles of ergonomics papers. Statement of Relevance: This paper reviews and discusses concepts from the study of complexity and maps them to ergonomics problems and methods. It concludes that humans are a major source of and solution to complexity in systems and that complexity is a powerful contingency factor, which should be considered to ensure that ergonomics approaches match the true nature of ergonomics problems. 相似文献

The International Ergonomics Association Technical Committee ‘Human Factors and Sustainable Development’ was established to contribute to a broad discourse about opportunities and risks resulting from current societal ‘mega-trends’ and their impacts on the interactions among humans and other elements of a system, e.g. in work systems. This paper focuses on the underlying key issues: how do the sustainability paradigm and human factors/ergonomics interplay and interact, and is sustainability necessary as a new approach for our discipline? Based on a discussion of the sustainability concept, some general principles for designing new and enhancing existent approaches of human factors and ergonomics regarding their orientation towards sustainability are proposed. Practitioner summary: The increasing profile of sustainability on the international stage presents new opportunities for human factors/ergonomics. Positioning of the sustainability paradigm within human factors/ergonomics is discussed. Approaches to incorporating sustainability in the design of work systems are considered. 相似文献

Abstract This paper examines the role of ergonomics in product and systems design. Market requirements as well as legislation have increased the use of ergonomics in design. This has increased the demands upon both ergonomists and designers. The ergonomist must learn to participate in the product development team. In return the design team must find the time and resources necessary for the inclusion of ergonomics in the development programme. This paper discusses the different roles played by the ergonomist in each stage of product and systems design. The need to give designers, engineers and management a fundamental education in ergonomics is highlighted as is the need for the ergonomist to consider the financial consequences of his work. 相似文献

This paper demonstrates that the goals of ergonomics (i.e. effectiveness, efficiency, health, safety and usability) are closely aligned with the goals of design for environmental sustainability. In this paper, the term ‘green ergonomics’ is conceptualised to specifically describe ergonomics interventions with a pro-nature emphasis. Green ergonomics is focused on the bi-directional connections between human systems and nature. This involves looking at (1) how ergonomics design and evaluation might be used to conserve, preserve, and restore nature and (2) how ecosystem services might be harnessed to facilitate the improved wellbeing and effectiveness of human systems. The paper proposes the scope of green ergonomics based on these bi-directional relationships in the areas of the design of low resource systems and products, the design of green jobs, and the design for behaviour change. Suggestions for further work in the green ergonomics domain are also made. Practitioner Summary: Given the enormous environmental challenges facing modern industrial society, this paper encourages ergonomics science to embrace a pro-nature understanding of work design and research. This paper sets out the role for green ergonomics based on an appreciation of the human–nature connections that have been integrated with our understanding of ergonomics science and practice. 相似文献

Abstract In recent years, there has been an increased use of back supports in US industry to reduce the frequency and concomitant costs of lower-back disorders. The obvious question is, ‘Can back supports relieve the load on the lumbar spine for employees engaged in industrial operations?’. This paper is directed towards answering this question because there have been mixed conclusions in the literature reporting on the efficacy of back supports. The literature concerning the biomechanical, physiological and psychophysical effects of back supports on the human spine has been reviewed as well as the use of back supports to control injury in the workplace. A'critical assessment of the findings reported by various investigators has been made together with a discussion of the mechanisms used by the trunk muscles to provide extrinsic stability to the spine. It is hypothesized that the extrinsic stability of the spine is manifested through more than one mechanism. These mechanisms may act simultaneously or sequentially to stabilize the trunk. Finally, the ergonomics of back supports as a corporate policy are discussed. 相似文献

Application of nanotechnology and nanomaterials is not new in the field of design, but a recent trend of extensive use of nanomaterials in product and/or workplace design is drawing attention of design researchers all over the world. In the present paper, an attempt has been made to describe the diverse use of nanomaterials in product and workplace design with special emphasis on ergonomics (occupational health and safety; thermo-regulation and work efficiency, cognitive interface design; maintenance of workplace, etc.) to popularise the new discipline ‘nanoergonomics’ among designers, design users and design researchers. Nanoergonomics for sustainable product and workplace design by minimising occupational health risks has been felt by the authors to be an emerging research area in coming years. Practitioner Summary: Use of nanomaterials in the field of design ergonomics is less explored till date. In the present review, an attempt has been made to extend general awareness among ergonomists/designers about applications of nanomaterials/nanotechnology in the field of design ergonomics and about health implications of nanomaterials during their use. 相似文献

Abstract The design of the early Olivetti VDU workplaces used the micromesh filter as an antireflection device. New ergonomic problems related to the use of the VDUs have forced the designers to adopt the etching treatment on new VDUs and to supply them with the micromesh filter only in cases of particularly highly lit environments. Afterwards, in order to give the operator the opportunity of using the preferred colour of the character, the designers set up coloured plastic filters, which also show good antireflection effectiveness. In this case, the choice of correct colours and the determination of the best compromise between antireflection effectiveness and character sharpness are the contribution of ergonomics to the design of the filters. In this paper the different antireflection devices and their ergonomic evaluation are presented and discussed. 相似文献

Traffic sign comprehension is significantly affected by their compliance with ergonomics design principles. Despite the UN Convention, designs vary among countries. The goal of this study was to establish theoretical and methodological bases for evaluating the design of conventional and alternative signs. Thirty-one conventional signs and 1–3 alternatives for each conventional sign were evaluated for their compliance with three ergonomics guidelines for sign design: physical and conceptual compatibility, familiarity and standardisation. Twenty-seven human factors and ergonomics experts from 10 countries evaluated the signs relative to their compliance with the guidelines. Analysis of variance across alternatives revealed that for 19 of the 31 signs, an alternative design received a significantly higher rating in its ergonomics design than the conventional sign with the same meaning. We also found a very high correlation between the experts’ ratings and comprehension from previous studies. In conclusion, many countries use signs for which better alternative designs exist, and therefore UN Convention signs should be re-examined, and ergonomics experts evaluation can serve as a good surrogate for road users’ comprehension surveys. Practitioner summary: This study presents theoretical and methodological bases for evaluating the design of UN Conventional and alternative traffic signs. Human factors and ergonomics experts evaluated 31 conventional and 68 alternative road signs, based on ergonomics principles for sign design. Results indicated the need to re-examine poorly designed UN Convention signs. 相似文献

Abstract This paper represents an effort to establish an inter-disciplinary field of research toward total educational effectiveness. The traditional educational delivery lacks any systems perspective and precision. The application of ergonomics to education has received only limited attention. A systems analysis has identified 5 components for educational ergonomics: (1) learning ergonomics, (2) instructional ergonomics, (3) orgonomics of educational facilities, (4) ergonomics of educational oqutpment, and (5) the ergonomics of educational environment. Learning ergonomics explores such areas as educational skills of handwriting, roading, drawing, instrument manipulation, class scheduling and school scheduling, research in examinations, management of learning activities, and grading systems. The instructional ergonomics covers textbook design, teaching devices, instruction techniques, classroom conducts, lecture preparation, and educational T.V. Ergonomics of educational facilities concerns educational furniture, laboratory and library ergonomics, classroom and office design, and equipment allocation. Ergonomics of education equipment investigates needs analysis, C/D design, allocation of equipment, performance analyses, and its safety and construction. Ergonomics of educational environment includes such things as illumination, colour, noise, space utilization, and allocation of equipment. Within each variable, research is reviewed and typical studies are suggested. The value of an integrated discipline of educational ergonomics is also discussed. 相似文献

Ergonomics has been a very important activity in the design process. However, ergonomics rarely includes the environmental requirements into the design of products. The article proposes and presents the Eco-Ergo model through its application to a real-world product, a washing machine, to allow designers and ergonomists to establish product design requirements in order to minimise environmental impacts related to user–product interaction during the use stage. This model uses a visual language of representation, Blueprinting-based, that helps designers explore problems they have not previously considered during the market research when a wide variety of products with different interaction elements is analysed. The application of this model allows direct efforts and attention on the user analysis phase in the most influential user’s actions on the environmental performance of energy-related products during use, establishing ergonomics requirements related to users behaviour at the initial design phase. Practitioner summary: This study provides a proposal to incorporate ergonomics into the practice of eco-design through the use of human factors in the establishment of initial eco-design requirements. This blueprint-based model combines an empirical and theoretical approach, based on the product test developed by designers, ergonomists and environmentalists.

A retrospective post-occupancy evaluation survey of 44 occupants in two Leadership in Energy and Environmental Design (LEED) Platinum buildings on a US college campus is reported. The Internet survey covered a range of indoor environment and ergonomics issues. Results show that working in these buildings were a generally positive experience for their health, performance and satisfaction. However, in one building there were persistent issues of variability in air temperature, air freshness, air quality and noise that affected the perceived health and performance of the occupants. Although the buildings were energy-efficient and sustainable structures, ergonomics design issues were identified. Implications for the role of ergonomics in green buildings and in the US LEED rating system are discussed. Practitioner Summary: This survey identified a number of ergonomics design issues present in the LEED Platinum energy-efficient and sustainable buildings that were studied. These results highlight the importance of integrating ergonomics design into green buildings as a component in the US LEED rating system. 相似文献

What has ergonomics done to improve the design of products, buildings and environments for handicapped people? The ergonomist, by assisting in the fitting of disabled people to tasks, products and environments designed for people who are not disabled, has made contributions in two main ways. This has been done in the first instance by the adaptation ofexisting facilities and the development of special aids. This is, however, a short-term solution to solve problems that exist now. The ergonomist has also done much to assist in the reduction of handicap for disabled people in the future by taking the capabilities and capacities of disabled people into account when developing new facilities. The major difficulties which the ergonomist faces in using and applying ergonomics to find generalizable solutions to the problems presented by disability in all its many varied forms are to do with measurement, classification and goals. These difficulties and ways of dealing with them are discussed. 相似文献

In complexity science, the many models thinking philosophy argues for a multi-method approach to complex problems. This article investigates whether the use of multiple systems ergonomics methods to examine the same problem is useful, or whether using different approaches creates incompatible analyses. Five systems ergonomics analyses of road trauma are examined and their key insights extracted. The extent to which these insights are compatible with one another and can be integrated when attempting to reduce road trauma is assessed. The findings indicate that applying several systems ergonomics methods to the same problem is useful, as multiple insights are developed and deficiencies in one approach are countered by the others. Importantly, the case study demonstrates that the insights gained are compatible and support the development of holistic systems thinking-based interventions. In conclusion it is recommended that a many systems ergonomics model thinking approach be adopted by ergonomists working in complex problem spaces. Practitioner Summary: Many model thinking uses multiple methods to understand complex problems. We explore whether this is beneficial in systems ergonomics. Five models of road trauma, developed using five systems ergonomics methods, are examined. The findings demonstrate that a many model systems ergonomics approach produces a diverse but complimentary set of insights. 相似文献
