L’aide à la décision comme cadre de gouvernance-innovation, Decision aiding as a framework of governance-innovation

Igor Crevits, Laurence Bonnafous, Said Hanafi

Dans cet article, nous avançons quelques arguments montrant que l’aide à la décision est utile pour soutenir une démarche d’innovation. Les concepts de l’aide à la décision permettent de caractériser finement une innovation, en la reliant à l’existant, comme une évolution et non comme une rupture.…, In this paper, we propose some arguments showing that decision aiding is useful for supporting an innovation approach. The concepts of decision aiding allow to finely characterize innovation, by linking it to the current situation, as an evolution rather than a disruption. The methodological…

Evaluation de la performance des blocs opératoires: du modèle aux indicateurs, Assessing Hospital Operating Rooms Performance: a framework and indicators

Frédéric Bonvoisin, Sondès Chaabane, Olivier Sénéchal, Christian Tahon

Dans cet article, nous présentons une méthodologie qui combine une approche pragmatique avec un outil d'aide à la conception, visant à générer un système global d'évaluation de la performance utilisable dans les blocs opératoires. Elle comporte quatre étapes: détermination de la stratégie…, In the current environment, hospitals need to develop performance assessment tools. Our purpose is an innovative methodology for reducing the existing deficiencies in healthcare performance. This methodology combines a practical approach with a design support tool for generating a global…

An evidential network approach to support uncertain multiviewpoint abductive reasoning

Felipe Aguirre, Mohamed Sallak, Frédéric Vanderhaegen, Denis Berdjag

The paper proposes an approach to support human abductive reasoning in the diagnosis of a multiviewpoint system. The novelty of this work lies on the capability of the approach to treat the uncertainty held by the agent performing the diagnosis. To do so, we make use of evidential networks to…

Coupling a genetic algorithm with the distributed arrival-time control for the JIT dynamic scheduling of flexible job-shops

Gabriel Zambrano Rey, Abdelghani Bekrar, Vittaldas V. Prabhu, Damien Trentesaux

In order to increase customer satisfaction and competitiveness, manufacturing systems need to combine flexibility with Just-in-Time (JIT) production. Until now, research on JIT scheduling problems has been mostly limited to high volume assembly lines rather than job-shop-like systems, due to their…

Fault Detection and Isolation of Aircraft Air Data/Inertial system

Denis Berdjag, Jérome Cieslak, Ali Zolghadri

A method for failure detection and isolation (FDI) for redundant aircraft sensors is presented. The outputs of the concerned sensors are involved in the computation of §ight control laws, and the objective is to eliminate any fault before propagation in the control loop when selecting a unique §…

Development of a new nonlinear numerical material model for woven composite materials accounting for permanent deformation and damage

Olivier Cousigné, David Moncayo, Daniel Coutellier, Pedro Camanho, Hakim Naceur, Steffen Hampel

Due to their draping, stiffness, improved ductility and damage tolerance properties woven composites are being increasingly used for the construction of crash-relevant structural parts. Textile composites may depict a nonlinear behavior along several directions. Moreover, considerably-thick…

Analysis of thin composite structures using an efficient hex-shell finite element

Seddik Shiri, Hakim Naceur

In this paper a general methodology for the modeling of material composite multilayered shell structures is proposed using a Hex-shell finite element modeling. The first part of the paper is devoted to the general FE formulation of the present composite 8-node Hex-shell element called SCH8, based…

Reduced numerical model to investigate the dynamic behaviour of honeycombs under mixed shear–compression loading

Rami Tounsi, Bassem Zouari, Fahmi Chaari, Eric Markiewicz, Grégory Haugou, Fakhreddine Dammak

Cellular materials such as aluminium honeycombs combine lightweight with an efficient crash energy absorption capability. They have a major role in a wide range of transport applications to reduce gas emission by the design of lighter structures but remaining safe in accident case. Many…

A comparison of the impact of CPOE implementation and organizational determinants on doctor–nurse communications and cooperation

Sylvia Pelayo, Françoise Anceaux, Janine Rogalski, Peter L. Elkin, Marie-Catherine Beuscart-Zephir

Objective To compare the impact of CPOE implementation and of the workplace organizational determinants on the doctor–nurse cooperation and communication processes. Method A first study was undertaken in eight different wards aimed to identify the different workplace organizations that support…

Relevance of Wavelet Shape Selection in a complex signal

Maxence Bigerelle, Gildas Guillemot, Zahra Khawaja, Mohamed El Mansori, Jérôme Antoni

In wavelet analysis, the signal reconstruction and statistical estimators are strongly influenced by the wavelet shape that controls the time-frequency localization properties. However, this dependency does not imply that the wavelet form is physically relevant to extract spatially invariant…
