To meet the expectations of system performances and to respect safety standards like ISO 26262, systems engineering and safety analysis have to be better integrated. In this paper we propose a conceptual framework and a method to define and verify the functional view of the logical architectures from a safety point of view

These proceedings cover the most recent trends in the emerging field of complex systems sciences & practices from an industrial and academic perspective, including the main industrial domains (aeronautics & aerospace, defense & security, electronics & robotics, energy & environment, health & welfare, software & e-services, transportation), scientific & technical topics (systems fundamentals, systems architecture & engineering, systems metrics & quality, systems modeling tools) and systems types (artificial ecosystems, embedded systems, software & information systems, systems of systems, transportation systems). The CSD&M Paris 2015 conference is organized under the guidance of the CESAMES non-profit organization, address: CESAMES, 8 rue de Hanovre, 75002 Paris, France

To fulfil the advanced needs of customers, OEMs (Original Equipment Manufacturers) start collaborating with service and technology providers to develop a customised package of heterogeneous tangible and intangible components. Consequently, defining the interfaces is crucial to integrate these components into a unique system. Comparing to the product or service design, modeling interfaces in PSS is challenging because of the heterogeneity of its components, especially, when a tangible component is interacting with an intangible one. This paper aims at proposing a conceptual model supporting the definition and classification of interfaces in PSS architecture. Based on Systems Engineering (SE) recommendations, the model allows the definition of interfaces through the system definition from the functional to the physical architecture. The application of the model is illustrated by a pragmatic use case concerning the self-service and station-less bicycle sharing system.

Il s'appuie sur une analyse effectuee dans quatre entreprises de la region. Elles connaissent le meme souci avec la qualite de leurs donnees techniques et ne savent pas comment estimer l'importance de la non qualite des donnees. Pour proposer une reponse a ces problemes, nous avons travaille sur quatre points importants. Une terminologie sur les dimensions de la qualite des donnees. Nous presentons les dimensions de la qualite des donnees selon 2 axes: la qualite du modele et la qualite des valeurs. Nous insistons sur la semantique des donnees: durant le cycle de vie d'une bd et selon son mode d'introduction dans l'entreprise. Une analyse de la qualite des donnees sur les bdt. Nous decrivons les causes majeures de la mauvaise qualite des donnees techniques et analysons l'influence de celle-ci sur les principaux traitements de la gpao. Nous montrons que le contexte dans lequel la bdt a ete developpee n'est pas neutre au regard de la semantique des donnees. Une etude des correlations entre qualite des donnees et resultats d'algorithmes. Dans les cas particuliers de l'ordonnancement en flow shop et du calcul de la quantite economique, nous montrons qu'il est possible de definir une politique de maintenance des donnees a partir d'un seuil de degradation des resultats. Une derive assez importante des donnees semble necessaire pour degrader considerablement les resultats. Une demarche d'evaluation et d'amelioration de la qualite des bdt. Nous presentons une demarche d'audit permettant de faire le point sur le niveau actuel de la qualite d'une bdt. Un exemple d'application industrielle illustre cette demarche. Les choix effectues lors de l'installation de la bdt peuvent etre remis en cause

This situation has been the driving force behind the development of many innovations in the elderly care. However, the success of these innovations depends on their acceptability. After a bibliometric study, we propose that the innovation acceptability is conditioned by the different preferences and multiple risks incurred by a group of stakeholders. This article focuses on the development of a global model for assessing and reducing the fall risk of seniors. This risk is studied in the context of innovations for home care.

This work was based on the need to enhance the integration of the customer needs into the design phases of SE. A joint methodology was proposed integrating the SE approach with the Design Thinking (DT). An analysis was conducted as part of a case study proposed by IBM Corporation for the development of a security system for a building. The results confirm that the insertion of the DT in the SE has a significant impact on the generation of concept solutions.
