International audience; The pandemics situationhas brought unforeseen challenges to all organizations at a global scale. While some strongly profit from it, others thrive to survive or already died. In suchtimesthe bulk of leadership and management related skills,gains a disproportional importance especially for organizations where most of their workforce stronglydepends on remote collaboration.Being aware of the difficultiesto manage collaboration within and between teams in “normal times”,the “still”ongoing situation hasonlybroughtmore complexityto organizationsin that aspect. In this work is proposed a model to manage organizational remote collaborative networks in order to identify collaboration extremes(lack of collaboration, or collaborative overload) which emerges as people work together in projects or operations,developed based in three pillars (collaborative networks, social network analysis, and business intelligence). A real case study is presented toillustrate the functioning principles of the model.
International audience; Since COVID-19, many educational institutions have focused their attention towards remote digital synchronous learning. While this new kind of learning brings some advantages, it also brings new challenges like keeping the students focused and engaged in the courses being given. Through this paper we introduce a learning strategy based on some of the principles of speed-dating, a tool that has been explored in the entrepreneurship world for networking, in order to maintain the students’ focus in the class activities and topics. The proposal was tested in a Process Automation course for Chemical and Biotechnology Engineers, which is usually not one of their preferred ones due to its complexity in relation to other courses. A framework for incorporating the activities in other courses is presented, along with preliminary quantitative and qualitative results to evaluate its efficacy.
International audience; In modern society, citizens aspire to get trusted and reliable digital services toauthenticate theirsto payments. With the COVID-19 crisis, online shopping's fast growthhas led citizens to increase registration in different systems.The registrationis typically done without any guaranteethat the involved businessentityis trustedand that private data is managed adequately, namelyaccording to the General Data Protection Regulation (GDPR). There are cases where online business adopts a federated authentication mechanism based on the existing and extensively adopted service providers, e.g., Facebook, and Google. With the European authorities' complacency, this de facto trendseems to contribute to a dangerous unregulated digital services model. While avoiding the centralization risks, a possible alternativeis to pursue the concept of regulated and competing digital online shops or services offered under a single collaborative model across Europe. Citizens aspire to getsimple mechanisms based on a single provider for authentication and pay anywhere, even with some associated costs. In this direction, wepropose a model thatconsiders regulated providers managing citizens' access to any online business in Europe, avoiding, in this way, the spreading of personal data across (business) organizations, thus decreasing the risk of personal data leaks. A collaborative network is foreseen to logically tie committedregulating authorities, providers, and digital online service providers. The proposedapproach is ground on our previous research on systems integration, collaborative networkinfrastructure, and unified mobility payment services. This position paper offers a digital strategy for citizens, designated by Digital Person Ecosystem (DPE), which relies on Collaborative Networks concepts and centered on public authority leadership.
International audience; The coronavirus crisis had a critical impact on supply chains and production worldwide. In particular, closed borders often prevented companies from obtaining the components required for their production. Such disruptions are the results of globalization, with suppliers spreading all over the world. The circular economy is an opportunity to overcome this challenge since components from end-of-life items may substitute supplies from afar. However, many barriers exist in the implementation of circular processes, as manufacturers perceive it as a radical change to their procedures. Therefore, we propose not to use completely new lines for the circular economy, but to use already existing systems. This paper presents the definition of circular integrated production systems (CIPS) and suggests a research roadmap for such to investigate what challenges and potentials arise, and what future research will be needed.
International audience; During the COVID19 crisis, Intensive Care Units admitted many patients with breathing disorders up to respiratory insufficiency. The care strategy of such patients was difficult to find and preventing patients to drift away toward a critical situation was one of the first challenge of physicians. In this study, we would like to characterize care pathways of patients that required a mechanical ventilation. The mechanical ventilation is an invasive treatment for the most critical respiratory insufficiencies. Through the analysis of the sequence of cares, we aim at supporting physicians to better understand patients evolution and let them propose new medical procedures to prevent some patients to be ventilated. This article proposes a method which combines a tensor factorization and sequence clustering. The tensor factorization enables to represent the care sequences as a sequence of daily phenotypes. Then, the sequences of phenotypes is clustered to extract typical care trajectories. This method is experimented on real data from Greater Paris university Hospital and is compared to a direct clustering of the sequences. The results show that the outputs are more easily interpretable with the proposed method.
International audience; Production ramp-up is a key stage in the product life cycle since it can determine whether a product’s launch into the market or the increase of production capacity succeeds or fails. Ramp-up as a phase of value creation, begins with the completion of a product’s design and ends with the reach of maximum production capacity. In today’s world, there is a significant advance in technology but simultaneously there is an increasing uncertainty as we have experienced with the Covid-19 crisis. Within this context, the importance of ramp-up management become more than ever evident. Whilst some products like face masks saw their demand increase drastically, some other companies had to shut off their production or switch to manufacture new products like hand sanitizers. Hence, it is critical today to have a successful ramp-up management in order to predict and meet clients’ demand in terms of quality and quantity. This paper aims to provide a set of guidelines for ramp-up management considering crisis context. The paper relies on an exploratory research coupling literature analysis and interviews among practitioners. The insights drawn from the literature and from the interviews are expected to provide decision makers with valuable guidance with regard to ramp-up management.

International audience; We conducted a pilot study to evaluate the potential and feasibility of back-support exoskeletons to help the caregivers in the Intensive Care Unit (ICU) of the University Hospital of Nancy (France) executing Prone Positioning (PP) maneuvers on patients suffering from severe COVID-19-related Acute Respiratory Distress Syndrome. After comparing four commercial exoskeletons, the Laevo passive exoskeleton was selected and used in the ICU in April 2020. The first volunteers using the Laevo reported very positive feedback and reduction of effort, confirmed by EMG and ECG analysis. Laevo has been since used to physically assist during PP in the ICU of the Hospital of Nancy, following the recrudescence of COVID-19, with an overall positive feedback.
International audience; This early work aims to allow organizations to diagnose their capacity to properly adopt microservices through initial milestones of a Microservice Maturity Model (MiMMo). The objective is to prepare the way towards a general framework to help companies and industries to determine their microservices maturity. Organizations lean more and more on distributed web applications and Line of Business software. This is particularly relevant during the current Covid-19 crisis, where companies are even more challenged to offer their services online, targeting a very high level of responsiveness in the face of rapidly increasing and diverse demands. For this, microservices remain the most suitable delivery application architectural style. They allow agility not only on the technical application, as often considered, but on the enterprise architecture as a whole, influencing the actual financial business of the company. However, microservices adoption is highly risk-prone and complex. Before they establish an appropriate migration plan, first and foremost, companies must assess their degree of readiness to adopt microservices. For this, MiMMo, a Microservices Maturity Model framework assessment, is proposed to help companies assess their readiness for the microservice architectural style, based on their actual situation. MiMMo results from observations of and experience with about thirty organizations writing software. It conceptualizes and generalizes the progression paths they have followed to adopt microservices appropriately. Using the model, an organization can evaluate itself in two dimensions and five maturity levels and thus: (i) benchmark itself on its current use of microservices; (ii) project the next steps it needs to achieve a higher maturity level and (iii) analyze how it has evolved and maintain a global coherence between technical and business stakes.
Extrait - 1ères lignes : Il a fallu attendre le 23 mars 2020 pour qu’une personnalité politique utilise à propos de la pandémie de Covid-19 le terme « précaution ». Encore faut-il noter qu’il ne s’agit pas d’un membre du Gouvernement, ni d’un expert de santé publique en charge de ce dossier, mais de Corinne Lepage, avocate et ancienne ministre de l’Environnement. Elle écrit : « On pourrait […] avoir un débat sémantique sur le point de savoir si en janvier, puisque c’est là que la ministre de la Santé, Agnès Buzyn, a tiré la sonnette d’alarme au niveau gouvernemental (et apparemment au niveau de la direction générale de la santé dès décembre 2019), il fallait parler à propos du coronavirus de prévention ou de précaution. Le débat pourrait paraître secondaire mais en réalité, il ne l’est pas. On rappellera que la précaution s’applique en cas de risque incertain et pour lequel le calcul des probabilités est impossible. Il s’agit en revanche de prévention lorsque le risque est connu dans ses effets et que les probabilités peuvent s’appliquer quant à l’importance de ses conséquences ». Comme l’indique Corinne Lepage début janvier et même en deçà, les pouvoirs publics français se trouvent face à la pandémie montante dans une situation d’incertitude qui relève typiquement de la précaution. Quatre indicateurs permettent d’avancer cela.
International audience; Since the beginning of the COVID-19 pandemic, students around the world have seen their schooling completely disrupted. Their teachers have had to reorganize in a hurry and even develop digital skills to be able to teach their classes synchronously but at a distance. Thanks to strong political incentives, both at national and university level, many tools have been massively deployed: digital learning management systems (e.g. Moodle), collaborative digital platforms (e.g. Google Meets, Microsoft Teams and Zoom) and even social networks (e.g. Facebook and Twitter). While this unprecedented health crisis has demonstrated the essential role of digital technologies in higher education, major questions arise regarding the quality of distance education, the learning process itself and the evaluation of knowledge and skills acquired at a distance. In this policy paper, about a hundred students from engineering schools and master's degrees in France were followed during several periods of confinement in order to provide some answers to these questions. The performance of the students in this very particular context is analyzed. The feelings of students, but also those of teachers, are also discussed, both on the use of digital technologies and on the digital transformation of higher education
