Problem solving methods as Lessons Learned System instrumentation into a PLM tool

Among the continuous improvement tools of the performance in enterprise, the experience feedback represents undoubtedly an effective lever of progress by offering important prospects for a progression in almost all the industrial sectors. However, several reserves to its use slow down the diffusion of its employment. We are interested in the installation of experience feedback system in a partner enterprise. In this paper, we propose an instrumentation of a Lessons Learned System (LLS) by problem solving methods (PSM) and its integration with a product lifecycle management (PLM). These proposals support an improvement of LLS performance and a facility of his application

Introduction

Arguably, modernism is indebted to romantic aesthetics, notably to the postulate that all areas of reality, be they noble or ignoble, can be represented and given shape through an original gesture of artistic creation. Indeed, in many modernist works, new zones of experience, new aspects of corporeality and sexuality, have gained both visibility and aesthetic dignity through the invention of experimental forms, as excretory body functions famously did in Joyce’s Ulysses. In the process, moder..

Proposition d'amélioration d'un système de retour d'expérience

L’objet de cette communication est de présenter des travaux portant sur le déploiement d’un système de retour d’expérience dans un progiciel PLM (Product Lifecycle Management). Ces travaux sont réalisés en partenariat avec la société Saft Bordeaux, spécialisée dans la conception et la fabrication de systèmes de batteries complexes. Nous commençons par définir la notion de système de retour d’expérience avec ses trois phases clefs (capitalisation, traitement et exploitation) qui le composent. Puis, à l’aide d’un audit réalisé auprès d’une trentaine d’acteurs impliqués dans le développement des produits, nous analysons les pratiques et outils actuellement employés à la Saft. De cette analyse, nous identifions les freins et les attentes des acteurs pour pouvoir réaliser un retour d’expérience efficient. Enfin, face à ces résultats, nous présentons les principes de la solution mise en oeuvre et les intérêts d’avoir couplé un système REx (Retour d'Expérience) à un PLM. Nous concluons en présentant les perspectives importantes qu’offre un tel travail

Automated Verification of Asynchronous Communicating Systems with TLA+

Verifying the compatibility of communicating peers is a crucial issue in critical distributed systems. Unlike the synchronous world, the asynchronous world covers a wide range of message ordering paradigms (e.g. FIFO or causal) that are instrumental to the compatibility of peer compositions. We propose a framework that takes into account the variety of asynchronous communication models and compatibility properties. The notions of peer, communication model, system and compatibility criteria are formalized in TLA+ to benefit from its verification tools. We present an implemented toolchain that generates TLA+ specifications from the behavioral descriptions of peers and checks compatibility of the composition with respect to given communication models and compatibility criteria

Jobs, News and Re-offending after Incarceration

We study how local labor market conditions and information about jobs affect recidivism among former inmates. Our identification strategy exploits daily variations on new job vacancies and news coverage of job openings and closings at the county level, merged with individual-level administrative data on inmates released from French prisons. Overall job creations do not affect recidivism, but inmates released when more jobs in manufacturing are created are less likely to recidivate. We also show that media coverage of job creation reduces recidivism, beyond actual employment opportunities, suggesting implications for crime-control policies: information about employment contributes to reduce recidivism

Link between domoic acid production and cell physiology after exchange of bacterial communities between toxic Pseudo-nitzschia multiseries and non-toxic Pseudo-nitzschia delicatissima.

International audienceBacteria are known to influence domoic acid (DA) production by Pseudo-nitzschia spp., but the link between DA production and physiology of diatoms requires more investigation. We compared a toxic P. multiseries to a non-toxic P. delicatissima, investigating links between DA production, physiological parameters, and co-occurring bacteria. Bacterial communities in cultures of both species were reduced by antibiotic treatment, and each of the diatoms was inoculated with the bacterial community of the other species. The physiology of P. delicatissima was minimally affected by the absence of bacteria or the presence of alien bacteria, and no DA was detected. P. multiseries grew faster without bacteria, did not produce a significant amount of DA, and exhibited physiological characteristics of healthy cells. When grown with alien bacteria, P. multiseries did not grow and produced more DA; the physiology of these cells was affected, with decreases in chlorophyll content and photosynthetic efficiency, an increase in esterase activity, and almost 50% mortality of the cells. The alien bacterial community had morphological and cellular characteristics very different from the original bacteria, and the number of free-living bacteria per algal cell was much higher, suggesting the involvement of bacteria in DA production
