To date little research has examined safety climate in relation to macroergonomics and how the two distinct sub-disciplines can be integrated to affect safety outcomes. The purpose of macroergonomics is to design a fully “harmonized” work system that improves numerous aspects of organizational performance and effectiveness, and this is accomplished by incorporating the foundational theoretical framework of sociotechnical systems theory (STS). Two broad subsystems within such a system are the personnel subsystem, the ways individuals perform tasks, and the technological subsystem, the tasks to be performed. Management is an important aspect of the personnel subsystem, and there is a growing body of research regarding supervisors’ influence over employee safety. One such area of research is safety climate, which is based on the perception of workers regarding safety and organizational practices. Two major factors of safety climate are management commitment to safety and communication pertaining to safety as a true priority from both top management and direct supervisors. This article describes the conceptual overlaps of macroergonomics and safety climate in order to present a conceptual model that integrates these domains using the framework of mesoergonomics. In conclusion, we discuss how this model can serve as a framework to guide the analysis and design of work systems and subsequent organizational interventions. 相似文献

It is a common complaint that the science of cognition does not do justice to either the reality of cognition in the wild or to the demands of engineering socio-technical systems. This article draws on examples from early functionalist/pragmatist views in psychology, modern physics and dynamical systems theory to explore the ontological basis of this complaint. Tentative steps are made toward a new way to frame an ontology of experience. In this framework, the duality (complementary nature) of control and observation is offered as an alternative to the dichotomy (independent nature) of mind and matter. 相似文献

Technology can take many forms from the development of sophisticated electronics to the application of basic procedural principles. Technology transfer can also take several forms, however, in this case, it is the transfer of technological principles between application domains that is of primary interest. This paper presents a framework (the Five ‘M’s framework) that can be used to consider the likely success of technology transfer. The framework is based upon a sociotechnical system approach. The framework is illustrated with an evaluation of the introduction of intelligent cruise control into motor vehicles. It is argued that this is a technological concept first developed as an aerospace application in the form of the autopilot. In this case, it is argued that the transfer of this technology in its current form may potentially compromise safety. 相似文献

To extend and deepen the roles of mediators in relation to sociotechnical change, this article first suggested an analytical approach which thereafter was used for analysing two cases illustrating two Swedish mediating organizations in different sectors at different time periods: the half state-/half industry funded Research Institute for Water and Air Protection, IVL, in the 1960s and 70s; and the Swedish Urban Network Association, SUNA, in the early years of the 21st century. We found that the associated sociotechnical systems changed through the actions of mediators and their organization of time-spatial specific settings. The mediator concept contributed to our understanding of these changes through a number of visible processes of translating rather than transferring specific knowledge, by functioning as a single entrance to knowledge, by supporting the selection processes, and sometimes by bridging knowledge in unforeseen ways. Overall, the mediating actors took on roles to promote the system and encouraged actors within the system to connect and develop both the system as such. 相似文献

Previous research has focused more on learning relative to forgetting despite both being generally recognized as important human performance issues. This research pursued an improved understanding of variables that impact the effectiveness with which humans can retrieve procedural knowledge, such as mathematics or programming. Two studies reviewed yielded varying results in experiments that investigated factors that can inhibit the retrieval of procedural knowledge from memory. To explore theoretical explanations for the opposing results, 32 human participants performed a resource management task in the multi-attribute task battery (MATB) manipulating task strategy and colour symbology. Human performance resulted in significant interference effects for a switch in strategy, but not with a change in the implicit meaning of colours. Therefore, the participants’ sensitivity to the implicit meaning of visual stimuli was not as significant as a more comprehensive change in rule structure associated with procedural knowledge. 相似文献

On functional periodicity as the basis for long-term stability of engineered and natural systems and its relationship to physical laws 总被引:1,自引:0,他引:1
In this research note, it is shown that for long-term stability, both engineered systems and natural systems must be either at a stable equilibrium state or have a functional periodicity. Examples are listed in a table. Classical physics such as Newtonian mechanics and thermodynamics are based on the existence of equilibrium states, whereas modern physics such as quantum mechanics and superstring theory suppose the existence of a functional periodicity. The particle/wave duality of matters that forms the basis of quantum mechanics is consistent with the stability argument presented in this paper. 相似文献

Growing complexity is one of the main reasons behind the failure of many projects. Thus, identifying and measuring complexity is crucial to the success of any project. Various schedule complexity indices have been proposed in the past, but a comprehensive complexity measurement tool encompassing factors of schedule along with other important project constraints, such as time and scope, is still missing. First, a theoretical framework consisting of 46 complexity factors has been developed through literature review followed by its refinement through a three-round Delphi study. The complexity factors are categorized into three categories, namely, Schedule complexity, Scope complexity and Cost/Resource complexity. The Project Execution Complexity Index (PECI) tool is proposed, followed by development of a questionnaire in order to compute PECI values and validated using three infrastructure development projects during the planning phase. Finally, in the execution phase, the performance of the projects is measured through earned value analysis. PECI values are then mapped with project performance indices (i.e., schedule/cost performance index) in order to assess the effect of project complexity on the performance of projects. The results showed that projects with higher complexity tend to have larger cost or schedule overruns. These case projects are also ranked according to the degree of their complexity on the complexity scale. This ranking can help decision makers to decide which projects should be included in the portfolio and which projects need prioritizing through assigning resources more efficiently. The proposed PECI tool may also help project managers to better anticipate prospective difficulties during the initial stages of the project lifecycle. 相似文献

This article seeks to identify performance-enhancing strategies that could be used to improve and optimise human–technology collaboration in rock drilling ‘activity’ in deep mines. Results from the analysis of miners’ motor actions during rock drilling activity showed that by using procedurally driven strategies, they were able to perform simultaneously two specific tasks that required high levels of concentration and visual control in the normal visual field available to them from inside the protective cabin of the high-technology equipment they were using. The miners simultaneously combine their mental actions and motor actions in recognising and remedying the constraining effects of unfamiliar stimuli during the rock drilling task. It is concluded that the functional efficiency and effectiveness of rock drilling as well as the miner's productive performance in future automated and digitised deep mines could be enhanced by identifying the procedural characteristics of their performance-enhancing actions and operational strategies. 相似文献

It is well known that the use of procedures is very important in securing the safety of process systems, since good procedures effectively guide human operators by providing ‘what should be done’ and ‘how to do it’, especially under stressful conditions. At the same time, it has been emphasized that the use of complicated procedures could drastically impair operators’ performance. This means that a systematic approach that can properly evaluate the complexity of procedures is indispensable for minimizing the side effects of complicated procedures. For this reason, Park et al. have developed a task complexity measure called TACOM that can be used to quantify the complexity of tasks stipulated in emergency operating procedures (EOPs) of nuclear power plants (NPPs). The TACOM measure consists of five sub-measures that can cover five important factors making the performance of emergency tasks complicated. However, a verification activity for two kinds of complexity factors—the level of abstraction hierarchy (AH) and engineering decision (ED)—seems to be insufficient. In this study, therefore, an experiment is conducted by using a low-fidelity simulator in order to clarify the appropriateness of these complexity factors. As a result, it seems that subjects’ performance data are affected by the level of AH as well as ED. Therefore it is anticipate that both the level of AH and ED will play an important role in evaluating the complexity of EOPs. 相似文献

Product development is a highly creative and knowledge-intensive process that involves extensive information and knowledge exchange and sharing among geographically distributed teams and developers. How to best integrate such heterogeneous product knowledge has become an extremely important knowledge management (KM) subject associated with product development. Product development knowledge integration and sharing is becoming a key issue in the enterprise KM. This paper addresses the challenges of product development knowledge integration and sharing during product development. The aim of this research work effort is to develop a method to enhance the integration and sharing of product knowledge during the development phase. This study presents a systematic approach to developing knowledge integration and sharing for product development. The proposed approach includes the steps for designing a framework of product development knowledge sharing, developing representation model for product development knowledge, designing product development knowledge sharing process, designing product development knowledge integration ontology, developing knowledge integration and sharing method for product development based on ontology, and implementation of product development knowledge integration and sharing method. The proposed method could bring out an efficient and proactive way for knowledge integration and sharing among product developers in the product development process. 相似文献

The objective of this paper is to illustrate the interconnections between the different phases (or tools) within the cognitive work analysis framework; the benefits of extending an analysis across each of the five phases are highlighted through these interconnections. The paper uses a command and control micro-world example to describe how each of the five phases can be used to describe the constraints within the micro-world domain from a different perspective. Based upon the social organisation and cooperation analysis, design requirements are extracted in order to develop role specific customisable interfaces for use within the micro-world. The interfaces have been specifically developed to communicate real time reconfiguration of the network through each of the individual interfaces; the reallocations of functions or roles are communicated to the actors through changes to the interface. 相似文献

Agile manufacturing systems work in a constantly changing global market, particularly assembly systems at the last stage of product differentiation. Meanwhile, sustainability is becoming a key issue for manufacturing strategy. This paper formulates a systemic criterion of sustainability in agile manufacturing and computes it through flexibility and complexity. It is defined as a ratio of utility and entropy as a sustainability measurement. Under a unified framework, utility allows one to quantify the contributions to agility, in particular system flexibility. Complexity is measured by entropy. Thus, an original complementary role of flexibility and the complexity of the system are proposed. Developed from the distribution of system states, the systemic approach to sustainability in terms of output evolution is enriched. Based on a simple assembly line integer model simulation, a first quantitative analysis illustrates the concepts introduced. 相似文献

We correlate thelevel of knowledge of certain formulas in agroup of individuals with certain regular, downward closed, sets of strings. We show that in suitable circumstances, all such sets can occur as
levels of knowledge but that the lack of synchrony, or the lack of asynchrony when there are only two processors in the group,
can create more or less severe restrictions. 相似文献

Suburban rainwater tanks have the potential to reduce household mains water consumption, but simply installing the technology does not mean rainwater is automatically incorporated into everyday practices. Exploring how rainwater is conceptualised in contrast to mains water, and the way it is used in household practices, provides insights into why rainwater tank households may not be using less mains water than households without tanks. Water saving strategies that promote rainwater tanks tend to focus on installation rather than how, why and where rainwater is substituted for mains water. While there is the assumption that rainwater tank households use less mains water, an investigation of rainwater practices have revealed influential social and cultural factors that extend far beyond installing a new technology. Drawing on a household water study involving 21 interviews and 1425 surveys in the Illawarra region, Australia, practice theory principles provided insight into how rainwater was conceptualised, revealing the ‘meaning’ of rainwater as an influential factor informing its everyday use. The historical, cultural and emotional meanings of rainwater contribute to shaping its use in everyday practices. Rainwater means different things to different people and it is this spectrum of meanings that inform the range of practices, and volumes of use. This study highlights opportunities for increased integration of rainwater into household practices, which may broaden the perceived uses and usefulness, reshaping it's meaning over time. 相似文献
