Philippe Braz dont les pièces revendiquent une place de plus en plus importante dans le théâtre contemporain, s’illustre comme l’un des critiques d’une société qui s’auto-détruit à cause de l’argent. Off-shore, lue sous l’angle sociocritique défini par Duchet, s’offre comme une argumentation pamphlétaire et risible qui interroge sur la place de l’homme dans la société capitaliste en dévoilant la fin d’une richissime famille poursuivie par son passé et contrainte à l’exil. Le dramaturge instruit son public sur les limites de la puissance financière mal acquise qui ne peut nullement échapper à la justice divine même si elle parvient à se jouer de celle des hommes. Il dresse un sombre tableau de la cupidité qui pousse l’homme à briser le lien social entre lui et ses semblables.

We analyzed their design work and evaluated if they need a new structured method to provide a real image to understand what is going on in the companies, what they do, use, and how they answer this problem. Also, we proposed to them the method developed by [1], [2], that aims to integrate the human factors and ergonomics (HFE) from the early design phase, and represented in the survey. The objective is, first, to verify the availability of designers to use a new method to help them integrate HFE into their design process and, second, to improve the presented method based on the integration of Lean principles into the design process. The survey has been answered by more than 50 experts in engineering design, which represented companies in France, Germany, and internationally in different sectors of activity such as machinery and equipment, industrial materials, automotive equipment, and products, in which we found quite a few cases of interactions between humans and machines.

An integer linear programming model was developed. The aim was to find optimal routes in superspace based on performance-based navigation. The optimal routes were found from a DIJKSTRA algorithm that calculates the shortest path in a graph. Simulations with python language on real traffic areas showed the improvements brought by surface navigation. In this work, the conceptual phase and the upper airspace were studied.

Dans les approches de conception traditionnelles, les informations liées à l'usage d'un produit ou d'un système sont souvent prises en compte dans la phase de conception détaillée, ce qui peut entrainer des modifications de conception ainsi que des itérations. D'une part, ces changements sont coûteux et chronophages. D'autre part, ils peuvent nécessiter quelques dispositifs sécuritaires et/ou des procédures supplémentaires d'utilisation. Nous avons proposé dans Sun et al, 2018 une méthodologie visant à considérer les informations d'utilisation d'un produit, ou d'un système industriel, dès les premières phases de conception. Ceci permet d'accélérer l'émergence d'un système sûr à l'utilisation, sans nécessairement avoir recours à des systèmes de sécurité (capteurs, barrières…) ni à des procédures certainement sûres mais pas nécessairement productives. Afin d'évaluer la perception de cette approche, par les entreprises, par rapport à des besoins concrets qu'elles pourraient avoir, et pour étudier l'applicabilité de la méthode proposée, nous avons proposé un questionnaire et mené un sondage auprès de 500 entreprises européennes et du monde. Les résultats de ce sondage sont présentés et analysés dans cet article.

Particularly in Senegal, the design of tools is generally done in a traditional way. Very often these tools suffer from reliability problems, modularity to facilitate their maintenance. Ergonomic problems are also encountered to adapt farming tools to the size, the age, and the morphology of users. In this paper, we propose a methodology for general approach for designing modular products. This methodology is then implemented in Product-BPAS, a software aimed to help designers and to evaluate the behavioral performance of products in the preliminary phases.

Considering all these requirements in the design and modeling process would facilitate an evaluation of the behavioral performance of the future product. Most works deal with aspects related to functional criteria whereas behavior is rarely taken into account in the search for solutions. In this paper, we propose a design approach for innovative modular products, easily maintainable and adaptable to different user profiles. In order to evaluate the modularity, we propose a method of semantic modeling. The semantic model obtained makes it possible to identify innovative modular solution concepts by solving technical contradictions taking into account both the functional characteristics and the behavioral performances. As an illustration, a case study is outlined.

El analisis del colector mediante balances de masa y energia no estacionarios aplicados a cada uno de los elementos componentes del colector permitio desarrollar un programa en Visual Basic que simula el comportamiento dinamico del colector ante variaciones de las condiciones de operacion y variaciones de los parametros de diseno (dimensiones del colector, tipo de material de cubierta y dimensiones, material de la placa absorbedora y sus dimensiones, eficiencia optica y tipo y espesor de aislamiento). Los resultados muestran que el software puede ser empleado para el diseno de colectores para calentamiento de aire, ademas de poder ser empleado para obtener las temperaturas de cada componente del colector y el rendimiento termico instantaneo. El software tambien ofrece los elementos para determinar la constante de tiempo que caracteriza la dinamica del c...

Nowadays, companies apply Lean tools to improve machines and systems performance in their use phase. Lean tools application on existing machines ensures some functionalities like (Reduce changeover time, eliminate wastes, Involve Human Skills, etc.). The purpose of this paper is to offer designers a design support method and tool to design a performant system (production system, machines, etc.) by integrating Lean functionalities from the early design phases, with a minimum of needs to improve the system in the use phase via Lean. For this purpose, we analyze the Lean principles and tools to identify functionalities provided by Lean. These functionalities are analyzed and classified to integrate them into the design of manufacturing systems in the context of Industry 4.0. A "Lean-System-Design" approach defines a systematic and detailed guide ...

Lean integration during the design phases might be a more appropriate solution, but this could be a source of some contradictions related to the machine performance and the usage requirements. In this paper, we propose an approach, based on Lean and Inventive Design Methodology (IDM-TRIZ), to identify and resolve these contradictions due to the Lean integration and also to provide innovative technical solutions. The approach is illustrated by the integration of the functionalities of the ''Single Minute of Exchange of Dies'' (SMED) and the ''5S'' method from the early design phase. A case study about the ''3D printer clogged nozzle'' outlines the feasibility of the proposed approach.

The trees on which data were collected were identified base on an inventory (Balogoun et al., 2016). These cashew trees were chosen randomly in a delimited plot of 400 m² in each plantation to assess the trees' density. In each plot, three DBH (Diameter at Breast Height: 1.30 m from soil) trees between 0-20 cm and three DBH trees between 20-40 cm were selected per plantation as replication, in each district. A total of 36 Trees were selected. 2.2 Methods of data collection tools The meteorologicals data (maximum and minimum temperatures (°C), and Rainfall (mm) were collected at the synoptic station of the Agency for Safety and Air Navigation in Africa and Madagascar (ASECNA) located at Bohicon (Southern zone); Savè (central zone); Natitingou (Northwest zone), Parakou (North-East zone) and Kandi (extrem north) (Bello et al., 2016). These data were therefore collected over 15 years (2000-2015).

The feature-based product decomposition is a principle which allows to carry out the concurrent designing. An approach directed to this problem is presented here. A fuzzy product model is developed based on feature decomposition. The independent regions of product, which represent the independent information, and interfacing micro-regions, which represent common information are the results of this approach. The application shows the interest of this approach.

The slots are specific allocated periods which allow an aircraft to land or take off in a saturated airport. Their attribution depends on theconfiguration of the airport, more particularly on its capacity. We maximize the confirmed demand in each slot and take the number of aircrafts and the number of manageable passengers with an optimal quality service into account. We used the CPLEX software so that to test the effectiveness of the linear model. Firstly, in the proposed model linear in integer numbers, any unmet demand was isolated. Secondly, the rejected demands by introducing a model and an algorithm of resolution based on the dynamic programming.

In an integrated design approach, the topological and geometrical model provided by traditional CAD-systems should be completed by semantic data. These ad- ditional descriptions and constraints are often expressed by feature structures, or by object-centered representations such as the EXPRESS language included in the STEP standard. Before using this EXPRESS Model for the Behavioral analysis, a coherence control is required. We propose to use DL as a formal tool in order to test this coherence. For this purpose, we flrst deflne a mapping from EXPRESS-G into the ALCNI description logic. An example is then given for product maintainability analysis.

The customization takes into account the product usage profiles, the users’ behaviors and the environmental factors. Depending on these contextual aspects the approach allows to elaborate specific documents for different maintenance tasks to be performed either by the customers or by skilled technicians. The documents must be updated dynamically to follow the utilization conditions evolution. An application is outlined for the case of automobile. In conclusion, we point out future extension of this work to improve the product availability using the PLM (Product Lifecycle Management) systems to collect and reuse contextual field data at design stage.

So it is difficult for users to find a piece of information they need amongst these huge amount of documentations. In order to support maintenance implementation process effectively, a task-oriented adaptive maintenance support (TOAMS) system is designed to provide an intelligent, adaptive electronic support for maintaining complex equipment according to user profiles and their work in hand. By building user model, task model, and product model, document model is configured by multiview and some pieces of semantic information are added into data modules. An agent based software application is being developed to support and allow a systematic utilization of the “adaptive response” by integrating it into the daily work of the technician. An applic...

Such products are present in a very fast growing number of industrial products like mobile phones, digital cameras, high standing automobiles, aeronautics or NC machines. Some of these products are mass consumption items such as mobile phones that are characterized by a relatively short commercial lifetime. And then these products are renewed after a few months. Dealing with all this growing amount of wastes generated, is a crucial environmental problem that is becoming a worrying situation. This article proposes an approach aimed to lifecycle design for the recyclability of mass consumption mechatronic products. In this paper, we firstly describe and analyze the mechatronic products behavior from reliability and recyclability viewpoints. Then, we propose an approach for designing such products in order to fulfill recyclability requirements by using a knowledge-based design adviser module.
