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.

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.

Many profit-oriented companies publish research outcomes in scientific literature. However, very few studies have focused on the capabilities that enable firms to engage in scientific disclosure with consequent potential benefits for the firm. We propose that specific investments are required in order to engage in scientific disclosure activities, since the disclosure process requires distinctive capabilities. This paper empirically analyses the relationship between the composition of industrial research labs' personnel, basic research and scientific disclosure capabilities. Our econometric analysis provides evidence that scientific disclosure requires specific human resource allocations, which supports the view that scientific disclosure is not just a by-product of standard R&D activities. © 2015 Elsevier B.V.

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.

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.
