STANDARDIZATION ,SMALL business ,MANUFACTURING processes ,SYSTEMS engineering - Abstract
In order to reduce time and costs, while maintaining a high level of product quality, effective implementation of systems engineering processes may be beneficial for small and medium-sized enterprises. However, applying a prescriptive generic system engineering standard in the enterprise, without any consideration of the company's organisation, background and context, is inappropriate. Moreover, due to severe resource limitations, the difficulties in following and complying with a standard are even more obvious in SMEs. In this context, this paper explores a framework to help SMEs evaluate the maturity of processes, promote a progressive deployment and standardisation of their engineering processes to manage manufacturing projects, based on the experience and practices underway in SMEs and with reference to international systems engineering standards. Our proposal is to stand by companies to help them evolve their engineering processes by progressively aligning them with systems engineering standards without disrupting the overall organisation and practices of the company.

International audience; In the beginning of 2022, the world is still fighting the crisis caused by the COVID-19 outbreak. The scientific community is still dedicating significant efforts to identify which are the better strategies to mitigate the pandemic and establish how and when to apply them. Modeling and simulation are a common method to replicate and foresee the behavior of the epidemic curve, but traditional analytical models are not capable to explain and reproduce the real evolution of the number of infections and deaths as they only concentrate in the epidemiological aspects of the virus. The COVID-19 crisis has an impact in all fundamental levels of society, and this is the reason why its modeling requires a global perspective and a holistic approach. Though the engineering scope is not common in the study of public health crises, this paper concludes that some engineering tools such as systems analysis and control theory may be the answer to build a high-fidelity model to support the decision-making facing the emergency.

Mécanique des fluides ,Environmental Control System ,Thermodynamic Cycles ,System Architectures ,Aeroplane Energy - Abstract
A prominent pathway for the aeronautical industry to meet contemporary challenges is to explore overall vehicular efficiency gains enabled by various functional and structural distributions and/or synergies between onboard systems. To that end, this paper combines analytical first-principle-based methods and principles of systems engineering and focuses on the Environmental Control System (ECS). The objective is to develop means for simple blank-sheet design of complete system architectures, which would help unlock potentially obscured parts of the system design space. Basic thermodynamics is employed, complemented with “Function- Behaviour-Structure-Experience” systems engineering framework. The method presented in the paper enables users to initialise the design from a primitive abstract system architecture described by elementary physical processes, and then carry out a sequence of decisions and design material systems architecture, i.e. concepts that respond to the system requirements. The preliminary results present development of architectures representative both of traditional pneumatic and innovative electrical ECS concepts. Energy consumption figures of merit (thermodynamic efficiency, exergy destruction rate) are used as guidelines during the design i.e. for a given flight condition, the designer can assess the influence of each choice on the overall system energy consumption. Trade-offs between architectural design choices and figures of merit are thus rendered transparent in preliminary architecture design. In this paper the figures of merit are based on thermodynamic energy efficiency; in perspectives the method can include other constraints such as e.g. weight, volume, cost, or other, with long-term objective of enabling a comprehensive multi-disciplinary multi-system aeroplane architecture design scheme.

International audience; COVID-19 recently grew as a major problem worldwide and is considered the pandemic of the third century. Among the issues in dealing with this pandemic is the urgency, the bad communication, the decentralization of decision and the mismanagement of this crisis. In order to address these issues, the authors propose the use of Internet of Things and Artificial Intelligence. The Internet of Things proposes several solutions to the aforementioned problems, while using the Genetic Algorithm in AI to calibrate the proposed generalized SEIR mathematical model. This model, when calibrated to the existent recorded and confirmed data in Lebanon, will help predict the number of infected individuals. Thus, it will better prepare for the fight with the virus.

Risk ,Autre ,Obsolescence ,Conceptual Design ,Systems Engineering ,Innovation - Abstract
Innovation is a vital element in the dynamic world we live in, aiming at add-ing value to developing new systems. Obsolescence on the other hand com-prehends the deterioration of the system or component capacity to operate when it is no longer suitable to fulfil the required function, even if it still operates and can be manufactured and supported. As innovative and obsolete products can be seen as opposites, the proactive management of obsoles-cence encompasses the principles of innovation. Obsolescence has so far been mainly addressed from a reactive point of view. Realizing the impact of the conceptual design phase on a system’s life-cycle cost, this paper presents how a model-based system engineering approach, proactively assessing obso-lescence risks, leverages with innovation considerations. In doing so, the pa-per builds on technology readiness levels (TRL) to identify critical compo-nents and innovation considerations. With clearly identified risks, designers can knowingly decide whether to improve a design, by making it robust and resilient, or to accept the risks and develop an obsolescence management plan. The paper is illustrated with an example from the automotive industry.

Autre ,Similarity function ,Ontology ,Case-Based Reasoning (CBR) - Abstract
Case-Based Reasoning (CBR) allows emulating the human inference of solutions to problems profiting from previous experience. The integration of CBR with ontologies, structured organization of semantic knowledge, has been in the attention for some time, aiming to create powerful knowledge-intensive systems capable of proposing appropriate solutions to problems. This entails having collected an appropriate number of previous cases as well as having established a suitable ontology for the application domain. This paper focuses on the integration of CBR and ontologies to support the case representation, case base storage, and semantic similarity estimation. Different alternatives for such integration are explored and the approach has been tested in the creation of a Decision-Support System for the design of predictive maintenance systems. This work opens the window to significantly improve the capabilities of a CBR system by using the knowledge materialization and the reasoning features of a specific domain ontology.

In order to lead successful projects, coordinating the different business units of a company is compulsory. This paper proposes a framework to make companies' practices evolve toward a better alignment of the business units based on their processes, and illustrates it with project management and systems engineering processes. Indeed, all the different organization units intend to serve the common global objective to satisfy the customer needs, and need to closely collaborate during projects. However, work organization in companies often leads to barriers between these stakeholders, with the result of an incoherent decision-making that may compromise project execution. Therefore, the issue of processes alignment from different domains lies at the very heart of ongoing research topics and ranks first among economic and industrial concerns. This paper uses a qualitative approach to show how different business units' processes can be integrated and illustrate this framework by aligning the systems engineering and project management processes within a certain engineering project context. By using the proposed framework, different teams (or even different companies, in a context of distributed enterprise) can align their practices, while also making them evolve toward a better compliance with standards.

Obsolescence is the fact that an entity (physical or logical) is becoming outdated or no longer useful and in this way is considered inappropriate. The objectives of this article are twofold. First, we seek to contribute to the understanding of obsolescence through two conceptual models. They enable, among others, to link the points of view of the external and internal actors of the system. This mapping is fundamental when it comes to solve the re-design problems posed by some obsolescence issues. The obsolescence management process consists of Prepare, Identify, Assess, Analyze, and Implement. The second objective is to offer two support tools for the Identify and Assess phases: House of Obsolescence and System Obsolescence Exposure Analysis. The first allows to map the changes, desired or imposed, by external actors to the critical components and functions of the system architecture. These latter are then analyzed using the second tool whose objective is to assign an obsolescence exposure index to the identified obsolescence issues in order to prioritize them for solution determination during the analysis phase. The tools make extensive use of the modeled system knowledge through the application of System Engineering. The application of the tools is then illustrated through a case study.

The widespread of Unmanned Aerial Vehicles (UAVs) in various application domains has questioned the design methods used by UAV manufacturers. Migration from document centric approaches to Model-Based ones has stimulated research work on modeling languages and tools that reduce cost development and time to market. Among the various benefits one may expect from using a Model-Based System Engineering approach, the paper essentially considers a model as a reference for early detection of design errors in the life cycle of UAVs. The paper proposes designers to model the UAV in SysML and to use the free software TTool for safety analysis. TTool includes a SysML model editor, a model simulator and formal verification modules that rely safety analysis on mathematics rather than chance. The method associated with SysML and TTool is applied to a UAV in charge of taking pictures.

International audience; In recent years, data visualization has received a lot of attention and widely applicate in many areas. Data is a treasure, a lot of valuable information hidden inside. While visualizing the hidden information concisely and intuitively is a critical task. In this paper, we explore how data visualization could support conceptual design. A specific conceptual design case for improving the fuel efficiency of wheel loader is implemented. By visualizing the complex fuel consumption data comprehensive for engineers to get insights, thus to support the decision making for a new product development. As a result, a table of classifying visual techniques by different features, and a prototype consisted of four approaches step by step to present complex data are proposed.

International audience; Operating a modern technical system, such as a train or aircraft, calls for good organised engineering, operation and maintenance to keep the system in an optimal operational condition. Predictive maintenance is being studied and has as aim to identify errors early enough to still be able to propose a suitable solution before a real incident occurs. After all, technical problems in service may lead to delays or even interruptions of service due to extensive repair actions, such as the replacement of components. Often, predictive maintenance aims at recognising patterns in time series of monitored data and classifying these patterns as known conditions (faulty or correct). As such it provides a vital source of information for maintaining a healthy operational status. However, these approaches are still in their early phases and rely still heavily on skill and experience from the expert. In this paper, the use of self-organising maps for predictive maintenance is being discussed, applied to data of a jet engine. The aim of the study was to assess the usability of such approaches to real-life situations, assessing the learning and validation phases.

Complex systems design involves many different stakeholders over time, with different stages of design and engineering running in parallel, as a system evolves, and requirements change. Current project management theory and practice do not suffice, if only for the fact that projects by definition have a known end. This chapter introduces an integrated approach to management of design and engineering of complex socio-technical systems that incorporates both systems design and engineering (i.e., technical management) and governance (i.e., organisational management) throughout a system’s lifecycle.

The aeronautics sector is currently living an unprecedented growth largely due to innovative projects. In several cases, such innovative developments are being carried out by Small and Medium sized-Enterprises (SMEs). For instance, in Europe, a handful of SMEs are leading projects like airships, large civil drones, or flying cars. These SMEs have all limited resources, must make strategic decisions, take considerable financial risks and in the same time must take into account the constraints of safety, cost, time and performance as any commercial organization in this industry. Moreover, today, no international regulations fully exist for the development and certification of this kind of projects. The absence of such a precise and sufficiently detailed regulatory framework requires a very close contact with regulatory instances. But, SMEs do not always have sufficient resources and internal knowledge to handle this complexity and to discuss these issues. This poses additional challenges for those SMEs that have system integration responsibilities and that must provide all the necessary means of compliance to demonstrate their ability to design, produce, and operate airships with the expected level of safety and reliability. The final objective of our research is thus to provide a methodological framework supporting SMEs in their development taking into account recent innovation and institutional rules of the sector. We aim to provide a contribution to the problematic by developing a specific Model-Based Systems Engineering (MBSE) approach. Airspace regulation, aeronautics standards and international norms on systems engineering are taken on board to be formalized in a set of models. This paper presents the on-going research project combining Systems Engineering and Project Management process modeling and taking into account the metamodeling problematic.

A dialogue between a pilot and a control tower serves as running example to demonstrate the benefits of complementary model analysis techniques: simulation, model checking, and verification by abstraction. The proposed method may be adapted to other modelling languages and tools.

Le secteur aéronautique voit actuellement arriver de nouveaux types d'entrants, des systémiers innovants, en majorité des Petites et Moyennes Entreprises (PME), souhaitant développer et commercialiser de nouveaux moyens de transport. Des projets comme les dirigeables, les drones civils de transports de marchandises, les drones dits « taxi aérien », deviennent ainsi des préoccupations sérieuses pour tous les acteurs du marché où la sécurité des personnes et des infrastructures est un enjeu majeur. Dans ce cadre, le processus de certification, cœur de l'activité aéronautique, demeure une activité critique. Le secteur aéronautique est une industrie très structurée, organisée selon de nombreuses règles, normes et standards qui ne facilitent pas l'arrivée de ces nouveaux acteurs. Les PME concernées requièrent un support méthodologique pour les accompagner dans leurs développements et faire face à la complexité du marché. Nous proposons d'aborder la problématique par une approche d'ingénierie système basée sur les modèles et une modélisation hiérarchisée des processus d'entreprise.

Agile methods are receiving a growing interest from industry and these approaches are nowadays well accepted and deployed in software engineering. However, some issues remain to introduce agility in systems engineering. The objective of this paper is to show an agile management implementation in an educational project consisting in developing a connected mobile robot, and to evaluate the issues and benefits of adopting an agile approach. Among the most famous agile management methods, SCRUM has been chosen to lead this experiment. This paper first presents the project and how students traditionally manage it, then it describes how Scrum could be used instead. It evaluates the difficulties and interests to introduce agility in this project, and concludes on the ability of Scrum to design, test and progressively integrate the system, thus providing an operational prototype more quickly.

“Cyber Physical Systems” (CPS), continuously connected to the rest of the world, communicating autonomously with other systems and with a certain degree of autonomy for taking decisions, pose certain challenges to industries, but to the training of the next generation of engineers as well. The inclusion of different aspects of CPS in the educational programs is important to prepare the students for the development of such systems. The paper aims at looking at the development of CPS, identifying where and how it is important to train the students in particular. The core of the paper is dedicated to multi-paradigm modelling as a key enabler for mastering the complexity of CPS and focuses on educational challenges and relies on the authors’ experience with the SysML tool TTool and the WoPANets tool that implements network calculus theory.

Obsolescence is the fact that an entity (physical or logical) is becoming outdated or no longer possesses the required level of performance. The objectives of this article are twofold. First, it is intended to contribute to the understanding of obsolescence propagation. Secondly, two supporting approaches for the Identification and Assessment phases are proposed: the House of Obsolescence and the System Obsolescence Criticality Analysis. The former allows the mapping of obsolescence propagation via dependencies, whether imposed changes are desired or imposed, by external actors to the system architecture. Whereas, the objective of the latter is to assign an obsolescence criticality index to the identified risks in order to prioritize them for solution or mitigation determination during the analysis phase. The tools make extensive use of the modeled system knowledge through the application of Systems Engineering. The application of these approaches is presented through an illustrative study.

- Abstract
This paper aims at identifying retrofitting possibilities to incorporate existing spacecraft into a network of federated satellite systems. The paper presents a systematic review of possible retrofitting options, such as direct modifications including replacement and addition of interfaces, and indirect modifications through the addition of intermediary federated negotiators. The paper considers existing frequency regulations for the analysis in the technical domain, but does not take into consideration how complex or time-consuming any legislative changes might be. Although the paper concludes that direct modifications of existing satellites are nonfeasible from a technical point of view, it identifies a possible scenario of retrofitting by adding intermediary negotiator satellites. The link budget for the intersatellite link between an existing satellite mission, such as SPOT-6, and a conceptual satellite negotiator was estimated. The work concludes that from a link budget point of view and existing technology, such a configuration can provide a slant range from several hundred to thousands of kilometers. The work defines models for trade-off analysis identifying correlations between satellite negotiator parameters and the number of covered satellites. The paper concludes proposing several possible satellite negotiator architectures and high-level technical requirements based on analysis of characteristics of existing and planned satellites.

Standard knock sensor signal processing typically consists of band-pass filtering followed by integration over a specified time/angular window. The resulting knock intensity serves as input to knock detection & correction part of an engine management system (ECU). While this treatment was initially performed by dedicated ICs, it has recently been implemented by ECU software, leading to a digital signal processing approach. In spite of some evident advantages of this approach, the processing method itself had not changed significantly. In this paper, the possibilities of taking better advantage of digital signal processing techniques are discussed and investigations on some possibilities for improving the overall knock detection performance by means of enhancing the signal processing techniques are presented.

This paper examines performance of the knock detection technique typically used in engine control systems, and the margin for possible improvement. We introduce a knock signal model and obtain an analytical result for the associated receiver operating characteristic of the standard knock detector. To show the improvement potential, we derive the theoretical upper bound of performance. A special case with unknown model parameters is also considered. Numerical results stimulate the research of improved detectors.

With the increasing availability of data for Prognostics and Health Management (PHM), Deep Learning (DL) techniques are now the subject of considerable attention for this application, often achieving more accurate Remaining Useful Life (RUL) predictions. However, one of the major challenges for DL techniques resides in the difficulty of obtaining large amounts of labelled data on industrial systems. To overcome this lack of labelled data, an emerging learning technique is considered in our work: Self-Supervised Learning, a sub-category of unsupervised learning approaches. This paper aims to investigate whether pre-training DL models in a self-supervised way on unlabelled sensors data can be useful for RUL estimation with only Few-Shots Learning, i.e. with scarce labelled data. In this research, a fatigue damage prognostics problem is addressed, through the estimation of the RUL of aluminium alloy panels (typical of aerospace structures) subject to fatigue cracks from strain gauge data. Synthetic datasets composed of strain data are used allowing to extensively investigate the influence of the dataset size on the predictive performance. Results show that the self-supervised pre-trained models are able to significantly outperform the non-pre-trained models in downstream RUL prediction task, and with less computational expense, showing promising results in prognostic tasks when only limited labelled data is available. • Self-supervised learning is investigated to address data scarcity in prognostics. • Fatigue crack propagation prognostics in structures based on strain data. • Synthetic dataset composed of multivariate run-to-failure strain time series. • Self-supervised pre-trained models improve RUL estimation performance.

Le marché de l'aviation fait face aujourd'hui à une croissance rapide des technologies innovantes. Les drones cargo, les taxis drones, les dirigeables, les ballons stratosphériques, pour n'en citer que quelques-uns, pourraient faire partie de la prochaine génération de transport aérien. Dans le même temps, les Petites et Moyennes Entreprises (PMEs) s'impliquent de plus en plus dans la conception et le développement de nouvelles formes de système aéroporté, passant du rôle traditionnel de fournisseur à celui de concepteur et intégrateur. Cette situation modifie considérablement la portée de la responsabilité des PMEs. En tant qu'intégrateurs, elles deviennent responsables de la certification des composants et du processus de fabrication, domaine dans lequel elles n’ont encore que peu d'expérience. La certification, qui requiert une connaissance très spécifique des réglementations, des normes et standards, demeure un processus obligatoire et une activité critique pour les entreprises de l'industrie aéronautique. C’est aussi un défi majeur pour les PMEs qui doivent assumer cette responsabilité de certification avec des moyens limités. Dans cette thèse, deux besoins majeurs sont identifiés: le soutien méthodologique n'est pas facilement disponible pour les PMEs; et les exigences de certification ne sont pas facilement compréhensibles et adaptables à chaque situation. Nous examinons donc des voies alternatives pour réduire la complexité de la situation des PMEs. L'objectif est de fournir un soutien afin qu'elles puissent être plus efficaces pour comprendre et intégrer les règles, les législations et les lignes directrices à leurs processus internes de manière plus simple. Cette thèse propose ainsi une approche méthodologique pour soutenir ces organisations. Développée en étroite collaboration avec une PME française, l'approche est composée d'un ensemble de modèles (métamodèle, modèles structurels et comportementaux) couverts par un mécanisme de gouvernance. The aviation market is facing nowadays a fast growth of innovative airborne systems. Drone cargo, drone taxi, airships, stratospheric balloons, to cite a few, could be part of the next generation of air transportation. In the same time, Small and Medium-sized Enterprises (SMEs) are becoming more and more involved in designing and developing new forms of air transportation, transitioning from the traditional role of supplier to those of system designer and integrator. This situation changes drastically the scope of SMEs' responsibility. As integrators they become responsible for certification of the components and the manufacturing process, an area in which they have little experience. Certification mandates very specific knowledge, regarding the regulations, norms and standards. Certification is a mandatory process and a critical activity for the enterprises in the aerospace industry. It constitutes a major challenge for SMEs who have to take on this certification responsibility with only limited resources. In this thesis, two major needs are identified: methodological support is not easily available for SMEs; and certification requirements are not easily comprehensive and adaptable to each situation. We examine alternate paths, reducing the complexity and bringing one step closer to solving the problem for the innovative SMEs. The objective is to provide support so that they can be more efficient to comprehend and integrate rules, legislations and guidelines to their internal processes in a simpler way. This thesis proposes then a methodological approach to support such organisation. Developed in close cooperation with a French SME in this situation, the approach is composed of a set of models (metamodel, structural, and behavioural models) covered by a certification governance mechanism.
