This paper compares the quality of facility location resulting from voting and that of a centralized decision. The focus is on the quality of the Condorcet solution, which is measured by the ratio of the Condorcet solution value to the global Weber solution value. Prior work defined on networks showed that the ratio is bounded by 3. We attempt to reduce the impact of topology by investigating the problem on the plane. In this case, the ratio is smaller than 2. The result suggests that, when reducing the impact of topology, although a solution originated via voting can be somewhat distant from the optimal solution obtained via a centralized system, it is much closer to optimality than previously suggested. © 2013 Elsevier Ltd.

As the link between sustainable development and art begins to shed a new light on organizational conceptions, this article considers popular music, and especially blues music. The conceptual process of the paper is to highlight the philosophical roots of Western aesthetics in order to propose a counterpoint based on popular and ordinary living sustained by popular music. By analyzing blues music as both a durable support and a natural process of everyday experience, we open a door to Chinese philosophy and psychology for HR Management based on the body-mind-spirit alignment. This perspective generates new and creative avenues for research in HR management, organizational theory, and business education. The major issue is then how to sensitize the ears of HRM so that it offers 'vital nourishment' in the workplace at a time when the cost of the depressive state of many an employee has become a proven risk. © 2016 Elsevier Ltd.

In this paper, we present a synthesis of our fundamental and theoretical research on human system integration and human in-the-loop system for enhancing human performance - especially for technical gestures, in safety critical systems operations such as surgery, astronauts' extra-vehicular activities and aeronautics. Grounding humans-systems integration engineering and design (modelling and simulation) on a formally and experimentally verified theoretical framework, is a necessity to make sure of human in-the-loop system security, safety and reliability. The rise issues concerned with scientific principles of human systems integration and rationale for human in-the-loop systems technical engineering and managerial specific rules. © 2011 Springer-Verlag Berlin Heidelberg.

This paper deals with imperfect preventivemaintenance (PM) optimisation problem. The system to be maintained is typically a production system assumed to be continuously monitored and subject to stochastic degradation. To assess such degradation, the proposed maintenance model takes into account both corrective maintenance (CM) and PM. The system undergoes PM whenever its reliability reaches an appropriate value, while CM is performed at system failure. After a given number of maintenance actions, the system is preventively replaced by a new one. Both CMas well as PMare considered imperfect, i.e. they bring the system to an operating state which lies between two extreme states, namely the as bad as old state and as good as new state. The imperfect effect of CM and PM is modelled on the basis of the hybrid hazard rate model. The objective of the proposed PM optimisation model consists on finding the optimal reliability threshold together with the optimal number of PM actions to maximise the average availability of the system.Amathematical model is then proposed. To solve this problem an algorithm is provided. A numerical example is presented to illustrate the proposed maintenance optimisation model. © 2012 Taylor & Francis.

This paper addresses a hybrid job shop problem with identical machines, where several blocking constraints can be taken into account in a same problem. A mathematical linear integer model is proposed to be able to solve optimally the problem with commercial software. Since this problem is NP-hard, we developed an evaluation function in order to be able to solve bigger problems with classical meta-heuristics, thanks to a blocking matrix, containing the blocking constraints encountered after each operation of each job. The benchmark problems are proposed at the end of this paper, and the obtained results validate as much the proposed method as the evaluation function quality and suitability. © 2015 IEEE.

Currently, Cyber Physical Systems (CPS) represents a great challenge for automatic control and smart systems engineering on both theoretical and practical levels. Designing CPS requires approaches involving multi-disciplinary competences. However they are designed to be autonomous, the CPS present a part of uncertainty, which requires interaction with human for engineering, monitoring, controlling, performing operational maintenance, etc. This human-CPS interaction led naturally to the human in-the-loop (HITL) concept. Nevertheless, this HITL concept, which stems from a reductionist point of view, exhibits limitations due to the different natures of the systems involved. As opposed to this classical approach, we propose, in this paper, a model of Bio- CPS (i.e. systems based on an integration of computational elements within biological systems) grounded on theoretical biology, physics and computer sciences and based on the key concept of human systems integration. © Springer International Publishing Switzerland 2015.

This conceptual paper investigates the common concern among managers that the physical separation of workers within a global virtual team may hinder the transfer of knowledge amongst the team members that is required to carry out their work efficiently, especially in the context of knowledge-intensive enterprises. Workers and work teams in knowledge-intensive enterprises are often involved in creative tasks that are carried out jointly and involve team members with diversified competencies exchanging knowledge related to their projects and assignments to create innovative outcomes. We investigate some popular creativity-enhancing techniques in the perspective of their use as catalysts for knowledge transfer in this context. We assess whether the use of these techniques may alleviate the limitations imposed on global virtual team members by their use of telecommunications and collaborative work tools that might otherwise adversely affect the effectiveness of the knowledge transfer. These techniques are designed to be used individually, by groups or within a virtual community. The physical and temporal separation of the global virtual team members does not hinder the knowledge-intensive dimension of these enterprises when aided by creativity-stimulating techniques. Therefore, we suggest that global virtual teams making use of creativity-enhancing techniques may be more efficient in transferring complex knowledge. © 2016 Springer Science+Business Media New York

In this article, we critique the "placeless" character of enterprise sustainability research and introduce the concept of the place-based enterprise (PBE), arguing that such enterprises offer a potentially important means of fostering ecological and social sustainability in local communities. Drawing on a variety of disciplinary perspectives, we offer a specification of the concept of place and explore the relationships between places and enterprises. We maintain that PBEs, whose resources, productive activities, and ownership are anchored in specific local places, and who themselves possess a sense of place, may be more likely than conventional enterprises to pursue locally beneficial economic, social, and environmental outcomes. A typology of PBEs and suggestions for future research are proposed. © 2013 SAGE Publications.

Thinking about human systems integration is thinking human, system and human-system for designing and organizing system of systems from human-machine level to socio-technological level. For critical human in-the-loop systems there is a strong need of reliability and consistency from modeling, development and life cycle systems. A main epistemic issue rises: does it exist a conceptual framework, both theoretical and experimental, that ensures reliability and consistency of human system integration design and organization? According to the Italian Renaissance painting perspective principles invention, our paper puts in perspective human systems integrations from theoretical biology to systems sciences, and it presents an isomorphic framework for modeling human systems integration especially adapted at the human machine level, for medicine, defense and aerospace. © 2013 Springer-Verlag.

Extending and modifying his domain of life by artifact production is one of the main characteristics of humankind. From the first hominid, who used a wood stick or a stone for extending his upper limbs and augmenting his gesture strength, to current systems engineers who used technologies for augmenting human cognition, perception and action, extending human body capabilities remains a big issue. From more than fifty years cybernetics, computer and cognitive sciences have imposed only one reductionist model of human machine systems: cognitive systems. Inspired by philosophy, behaviorist psychology and the information treatment metaphor, the cognitive system paradigm requires a function view and a functional analysis in human systems design process. According that design approach, human have been reduced to his metaphysical and functional properties in a new dualism. Human body requirements have been left to physical ergonomics or "physiology". With multidisciplinary convergence, the issues of «human-machine» systems and «human artifacts» evolve. The loss of biological and social boundaries between human organisms and interactive and informational physical artifact questions the current engineering methods and ergonomic design of cognitive systems. New developpment of human machine systems for intensive care, human space activities or bio-engineering sytems requires grounding human systems design on a renewed epistemological framework for future human systems model and evidence based "bio-engineering". In that context, reclaiming human factors, augmented human and human machine nature is a necessity. © 2014 Springer International Publishing Switzerland.
