Mourier, Pascal. "Délocalisations industrielles compétitives." Paris 9, 1990. https://portail.bu.dauphine.fr/fileviewer/index.php?doc=1990PA090008.
This doctoral thesis is about plant relocation. This is a thesis of industrial organization focused on plant; we will try to demonstrate that the turbulent environment nowadays causes frequent relocation of existing plants. Therefore, these firmmust learn to master and manage the plant relocation process. In a first part of the thesis, we have tried to understand the relocation phenomenon and determine how location and relocation articulate one with the other. The second part aims at analysing the plant relocation at the firm level and answer such questions as: how to work out plant relocation, which ruptures can we identify and how to manage them?
Langlois, Julien. "Vision industrielle et réseaux de neurones profonds : application au dévracage de pièces plastiques industrielles." Thesis, Nantes, 2019. http://www.theses.fr/2019NANT4010/document.
This work presents a pose estimation method from a RGB image of industrial parts placed in a bin. In a first time, neural networks are used to segment a certain number of parts in the scene. After applying an object mask to the original image, a second network is inferring the local depth of the part. Both the local pixel coordinates of the part and the local depth are used in two networks estimating the orientation of the object as a quaternion and its translation on the Z axis. Finally, a registration module working on the back-projected local depth and the 3D model of the part is refining the pose inferred from the previous networks. To deal with the lack of annotated real images in an industrial context, an data generation process is proposed. By using various light parameters, the dataset versatility allows to anticipate multiple challenging exploitation scenarios within an industrial environment
Nadel, Simon. "Changements organisationnels, structures industrielles et innovations environnementales : le cas des firmes industrielles françaises." Thesis, Toulouse 1, 2014. http://www.theses.fr/2014TOU10033/document.
This thesis analyzes the determinants of environmental innovations at the firm level. It reviews the economic literature underlying the analysis of environmental innovation. Then it operationalizes the main concepts of this literature from three empirical angles. The first study explores the firm-level determinants of environmental innovations for all French industrial firms according to their three strategic orientations, i.e. regulation-oriented, supply-oriented or demand-oriented. The second study examines the complementarities between environmental innovations and organizational changes and emphasizes the organizational dynamics triggered by the adoption of an Environmental Management System. The third study highlights the coevolution of environmental innovation behavior at the firm level and sectoral systems of innovation. Ultimately, the thesis demonstrates that environmental innovations always result from specific combinations of internal and external rationales at the micro economic firm level. These specifications involve intra-organizational complementarities and interactions processes with industrial structures

As in brittany and in the e. E. C. , the dairy production of the "nord-finistere" swells sensibly from the beginning of the sixties to nineteen eighty-four. From this last date, coercive application of the dairy quotas announces not only an important decline of the collected quantities but more generally a deep reorganizing in this field, while, in the same time, especially since 1990, an environmental consciousness has come into view. With these new data that impede their collecting development, dairy industries of the "nord-finistere", mainly specialized in basic products, have multiplied diversificated producing. New makings, within but more and more outside the dairy industry, allow to increase added value which was for a long time low in brittany. Due to numerous and diversificated marketing campaigns, dairy industries from the northern part of the "finistere", are really weighing on the economical activity of the district. All of that isn't without inducing a positive impact on the employment rate or generating strong financial feedbacks

New materials technology represents a very complex field extending to social, economical and political aspects. In that study we have focused on technical-economical considerations, although social regards have been not neglected. We emphasize the importance taken by new materials technology on some current transformations arising on the industrial system of developed countries. They have been restructured to take further advantage from new techniques, especially regarding applications of new materials, and to be well adapted to a work organisation, with some consequences on developing countries, producers and transformers of mineral raw materials
PAN, YIAOJUAN. "Les societes industrielles d'administration en chine." Paris 1, 1994. http://www.theses.fr/1994PA010280.
The administrative industrial companies are very particular bodies. Aswelle as being economic entities endowed with legal status, whose activities are mainly industrial and commercial, they are also organizations who, in the name of the state, administrate the industrial economy. This multi-purpose role mains that the administrative industrial companies are very bureacratic in nature, the direct opposite to what private industrial companies, in the true sense, should be. This, of course, does not helf towards the development of a free national economy and the economic reform. Consequently, the administrative industrial companies must be reformed

Lignins are renewable and natural polymers. It is the most abundant polymer on the earth after cellulose. Nowadays, lignins are not fully exploited and only 2% of lignin is valorised per year, their principal application remaining as a combustible in pulp industries for energy production. In Quebec, 130000 tons of black liquor containing lignin could be available from Kraft industry, per year, in order to valorise them, without disturbing the mill production. Its valorisation could contribute to create new value added products like bio composites with a matrix of polyethylene, recycled polystyrene or even wood. These new products of these industries could improve the economic situation in this field, but also could bring new knowledge in the eco materials field, in contributing of the decrease of greenhouse gases in favoring the natural product against the synthetic product. Lignin structure is different depending on several parameters (origin, isolation process…). In this project, two Kraft lignins will be precipitated from black liquor of two Quebecoise paper industries using carbon dioxide as the reagent. These lignins will be purified and compared analytically to others lignins; one Kraft softwood commercial lignin, one pyrolytic lignin and one Soda lignin Protobind 2400. With the knowledge of the Kraft lignin structure, it will be easier to modify these lignins. The esterified Kraft lignins with maleic anhydride and succinic anhydride will be compared to the unmodified lignin according to several analytical technical as FT-IR, TGA, DSC, NMR. Maleated and non modified Wayagamack lignins were incorporated in biocomposite of recycled polystyrene and the mechanical and thermal properties and the morphology were studied. The composite with non modified lignin showed good mechanical and thermal properties compared to the composite with maleated lignin where the maleated lignin was still compatible with the recycled polystyrene The Windsor succinated and non modified lignin were used as a binder in a wood panel and their properties were also studied. The results showed the best mechanical properties for the wood panel containing non modified Kraft lignin. Condensation reactions of Kraft lignin during the hot-pressing of the panel improve the solidity of the panel unlike esterification reactions that could take place between esterified lignin and the wood hydroxyls. Key words: Black liquor, Lignin, Kraft process, Characterisation, Esterification, Composite, Valorization, Polystyrene, Wood.

The validation of experience is here developed around a theme concerning the electropneumatic servocontrolled. A first part lists the interests and contributions to research work in order to use them in the realization of innovative industrial products and using multidisciplinary knowledge. Then we show that the practical experience of previous activities, followed by critical analysis and reflection, led to the creation and active participation in standardization activities at international level. Finally a synthesis and formalization of these research activities and innovative industrial applications led to the development of training activities. A second part develops the theoretical and technical approach to better understand and assess the technological leap required for the creation and adaptation of innovative industrial products servo axes and modulators of electro power from market demands more or less formalized. Throughout this document the interactions between industrial and academic research aspects are discussed. This interaction leads to mutual enrichment acquired through experience

The oxidation behavior of quasicrystalline and approximant compounds has been studied in near industrial environnement, together with the subsequent evolution of their wetting properties. Two alloys have been selected: the icosahedral phase of the AlCuFe system and the O1 orthorhombic approximant of the decagonal phase in the AlCuFeCr system. Samples were either sintered pins or powders. Caracterisation techniques include X-ray diffraction, transmission electron microscopy, photoelectrons spectroscopy and laser ellipsometry, carried on specimens after just the surface preparation, i. E. Polishing, and atter oxidation cycles. It has been shown that the alloy chemistry prevail on the structure regarding the oxidation behavior. Because these intermetallics are Al-based, amorphous alumina is always formed on the surface. Depending on the oxidation conditions, the other chemical species can also oxidize. Ln the studied temperature and atmosphere ranges, depassivation is experienced either above 300ʿC and in boiling water. When oxidizing the icosahedral phase, a reservoir effect is proposed to explain occurring phase transformations. Non-wetting behavior was also studied just atter surface preparation and atter oxidation. Non- wetting properties are related to the complete surface system being the intermetallic substrate, the oxide(e) layer(s) it promotes and the extreme surface -carbon layers, hydroxides and hydroxyles bonds-. During cycles at 500ʿC, a reversible behavior is experienced

Hountondji, Guéliffo. "Commerce extérieur et démographie des entreprises industrielles." Nice, 1995. http://www.theses.fr/1995NICE0004.
Very little research has been done on the relationship between external trade and industrial firms' demography. International trade is traditionally assumed to provide a source of discipline on market performance, when industry move from autarky to foreign competition. In price cost margins models, such competition is expected to exert a significant and negatve effect on industry profit rates. Any kind of extension of these models to industrial firms' demography shoul d then posit a relationship between external trade and business failure rates. The dissertation examines first, systematically, the wole set of dependencies that may link industrial demography to sellers' concentration and profitability. Models derived from structure-conduct-performance paradigm are proposed and tested on the case of french industry, for the period 1987-1990. The relevence and the limits of trade discipline are exibited. Secondly, a framework for oligopolistic competition is developed within which foreign competition is viewed without any autarky hypothesis. In this framework, models of simultaneous equations are proposed to explain different business emerging and failure rate s econometric tests on the french case are performed

To analyses industrial process behavio, many kinds of information are needed. As tye ar mostly numerical, statistical and data analysis methods are well-suited to this activity. Their results must be interpreted with other knowledge about analysis prcess. Our work falls within the framework of the application of the techniques of the Artificial Intelligence to the Statistics. Its aim is to study the feasibility and the development of statistical expert systems in an industrial process field. The prototype ALADIN is a knowledge-base system designed to be an intelligent assistant to help a non-specialist user analyze data collected on industrial processes, written in Turbo-Prolong, it is coupled with the statistical package MODULAD. The architecture of this system is flexible and combing knowledge with general plants, the studied process and statistical methods. Its validation is performed on continuous manufacturing processes (cement and cast iron processes). At present time, we have limited to principal Components analysis problems

The eighties stand as a key point in the french economic and social history. For the first time ever for more than 20 years, we witness the setting of a wide national concensus focused on the company. In a situation of economic slump and in a perspective aiming at the opening of a large european single market, the phenomenon of birth of companies has a specific part to play simultaneously for social, economic and strategic reasons. On the whole, this last decade has been profitable for the new companies. On the one hand, from a social and cultural point of view, the manager's role has been more considered by the society than in the past. On the other hand, new schemes of assistance and support to the creation of companies were set up and progressed. Last but not least, public institutions and many private associations have set up specific processes to stimulate the creation scheme and help newly born companies to start with their activities. The analysis of the statistic data proves that the creations of companies occur as a concentrated phenomenon in a small number of regions. Globally speaking the young units can be seen as individual small-size ventures, operating in the field of services. But their most astonishing feature lies in their very big economic weakness. Thus french companies demography is caracterised by a positive evolution in their number of creations, counterbalanced by a strong trend towards failures. On the whole the generating process of the economic structure is assured, but the rates of renewal remains comparatively low as compared to the most industrialised countries

The region of Sanaga Maritime is crossed by the river Sanaga. There are numerous waterfalls ail across this territory. It is therefore an agricultural region by nature. The early construction of two hydroelectric barrages at Edea and Songloulou respectively, made it the most industralized region of Cameroon. Before colonization, the Mbenes, inhabitants of the Sanaga Maritime region were depended for their living on agriculture, hunting and fisching. After decolonisation, and finally after the take over of the economic and social sector by the nationals, there followed an immediate decline in the development of the region. The purpose of this research is to analyse all the stages of these social changes, suggesting solutions

Particulate air pollution constitutes one of the major risk factors implicated in the high incidence of respiratory and cardio-vascular pathologies. In order to integrate the variation linked to emission sources and seasons, atmospheric particulate matter (PM₂.₅) were collected at Dunkerque under urban (u) and/or industrial influence (I) and at Rubrouck (R) under rural influence, in spring-summer 2008 and autumn-winter 2009. The physico-chemical characterization of the six particulate samples has shown a fine granulometry (79 to 98 % < PM₂.₅) and a specific surface of 3 to 6 m²/g. Their concentrations in ionic species as well as in major metallic elements were different (Fe > Al > Mn > Zn > Cu > Ti ; I > U > R). Differences were also been observed in their organic element constitution (PAH : I2 > U2 > I1 > U1 > R2 > R1 ; PCDD/F and PCB : I2 > I1 > U2 > U1 > R1 > R2) with respect to considered influences (PMindustriel > PMurban > PMrural) and sampling seasons. After in vitro evaluation of particulate samples global cytotoxicity in human bronchial epithelial cells (BEAS-2B), we had shown the capacity of the organic components absorbed to the surface of these particles to induce gene expression of xenobiotic-metabolizing enzymes (CYP 1A1 and 1B1, and to a lesser extent, NQO1). Moreover, excessive intracellular production of reactive oxygen species within BEAS-2B cells exposed to the six PM₂.₅ samples induced oxidative damage (MDA production, 8-OHdG formation and/or glutathione status alteration). There was also a development of an excessive inflammatory response based on statistically significant increases in gene expression and/or protein secretion of cytokines (notably IL-6 and IL-8). These obtained responses were dose and/or time dependant. However, we couldn't observe mutations in the principal acting genes in the pathway EGFR/KRAS/BRAF

The decline of the "Henry Ford" system of manufacture has led us to make a strategic redefinition of the big business organization, with a view to incorporating in it new parameters which form part of a global process of dematerialisation. The major changes affecting firms - changes that are accentuated by the phenomenom of globalisation - appear to highlight the insufficiency of those key values which come out of materialist doctrines of the previous period : rationalism, cartesianism, mecanism, positivism, etc. , thanks to which the capitalist, institutional business entity was able to form itself in a coherent, orderly, secure and long-lasting, all of which satisfied the prevailing mentality at the time. Various different clear signs enable us to ask questions about the uncertain future of the post-industrial firms. The crisis about sense and legitimacy affecting them is worrying to a point that is has led to reactions amongst researchers, and suggests that this crisis will tend to become a primary and unavoidable fact for anyone studying this matter in depth. .

A technological revolution in the transport and communication sectors, together with a reduction of political and institutional uncertainties in many countries characterized by a relative abundance (and thus cheap) of unskilled labor give tremendous new incentives to firms to offshore outsource some parts of their productions to the South and/or to East European countries. This phenomenon, with its spectacular consequences on industry activity and employment, is one of the major concerns of the policy makers in developed countries today. The objective of this dissertation is to appreciate the effects of industrial delocalization both analytically and numerically. In line with a recent literature of heterogeneous firms in international trade, we highlight the mechanism of Technology upgrading of firms and Skill upgrading of workers induced by globalization, which acts against the Stolper-Samuelson curse, with the outcome that everyone could gain in real term. We extend the model in several interesting directions – the case of multi-product firms, the case of a two-sector economy, a case with endogenous growth, etc. – and confirm our positive welfare predictions

The industrial growth in the rural area of the Auxerrois is a moderate but significant one, stimulated by the nearness of the Parisian market. The entrepreneurs are mostly lower middle class. Communication is limited. Successors are not designated, they are often chosen by consensus. All this is a long way from the "factory system". Freedom of enterprise, which is steadfastly accepted, replaces authoritarianism. Bookkeeping remains basic. According to tradition, investments in industry are limited. Many entrepreneurs are satisfied with local markets. They need little capital, they seldom resort to credit, self-funding is a general rule. Technical innovation emerges slowly (and rather late) and strives to weave its way into the fabric of the old system. Capital investments are still limited, but they do increase. Innovations spread slowly although inventive spirit is not lacking. Most entrepreneurs get undoubtedly richer but social climbing is slow. There is a lack of continuity within the enterprises. The temptation is strong to transfer the funds from industry to land ownership or stocks and shares. Former social practices are still intact, but apprenticeship is on the decline as early as 1835. Protoindustrialization fails in the realm of textiles but develops in the ochre industry in an innovative form. In the county as well as in Auxerre, it seems that there is a strong sense of rootedness and little social unrest. The evolution of industry follows the same pattern as that of the "radical" movement in politics. From 1866-1885, the balance is disrupted

La validité des modèles des générateurs est essentielle aux analyses de stabilité et de performance dynamique des réseaux électriques. Les producteurs d’énergie doivent fournir aux transporteurs d’électricité les paramètres électriques dynamiques du modèle de tous les générateurs mis en service après 1990. Les paramètres fournis doivent obligatoirement être validés par des mesures expérimentales. En Amérique du Nord, la procédure d’estimation des paramètres la plus acceptée est l’essai de courtcircuit brusque. Pour des cas de réfection, les risques élevés de bris peuvent devenir inacceptables. L’essai SSFR (« Standstill Frequency Response ») décrit dans la norme ANSI/IEEE Std 115-2009 comporte plusieurs avantages par rapport aux méthodes plus traditionnelles, notamment l’amélioration de la précision des modèles sur une bande passante plus large (> 200 Hz) et l’élimination des risques d’endommager le générateur. L’objectif du projet de recherche est de développer un système de mesure automatisé répondant à des contraintes industrielles afin d’assister la réalisation de l’essai SSFR sur de grands alternateurs hydrauliques. La solution proposée vise à maximiser la qualité des mesures tout en minimisant le nombre d’interventions manuelles et la complexité du montage expérimental. Le système a été utilisé pendant plus de deux mille heures afin de réaliser des essais de validation sur des générateurs de 5.4 kVA. Les essais ont permis de démontrer que le système est robuste et qu’il possède les spécifications requises pour effectuer des essais SSFR répondant aux exigences de la norme ANSI/IEEE Std 115- 2009. Les trois premiers chapitres du mémoire introduisent les bases théoriques liées à la modélisation dq0 d’un générateur synchrone, puis décrivent les principaux essais permettant l’identification des paramètres du modèle. La seconde partie du mémoire se concentre sur les divers aspects de conception du système de mesure automatisé.
Generator models validity is essential to analyze power grids stability and dynamic performance. Energy producers must provide power carriers with the model parameters of all generators commissioned after 1990. The parameters supplied must be validated by experimental measurements. In North America, the most accepted parameter estimation procedure is the short-circuit test. For repair cases, the high risk of damaging the alternator may become unacceptable. The SSFR (« Standstill Frequency Response ») test described in the ANSI / IEEE Std 115-2009 standard has several advantages over more traditional methods, namely an improvement of the models accuracy over a wider bandwidth (> 200 Hz) and the elimination of the risk of damaging the generator. The research project objective is to develop an automated measurement system meeting industrial constraints in order to assist the realization of the SSFR test on large hydraulic alternators. The proposed solution aims to maximize the quality of measurements while minimizing the number of manual interventions and the complexity of the experimental setup. The system has been used for more than two thousand hours to perform validation tests on 5.4 kVA generators. The tests demonstrated that the system is robust and has the required specifications to perform SSFR tests that meet the requirements of the ANSI / IEEE Std 115-2009 standard. The first three chapters of the thesis introduce the theoretical framework related to the dq0 modelisation of a synchronous generator, then describe the main tests allowing the identification of the model parameters. The second part of the thesis focuses on the various design considerations of the automated measurement system.

The work of thesis deals with multiaxial fatigue. Its purpose is the fatigue life assessment of industrial structures submitted to any kind of solicitations, from the most basic case, which is uniaxial and periodical, to the most general one, which is multiaxial and of variable amplitude. The first part is dedicated to the study of multiaxial fatigue stress-based criteria. 37 criteria issued from the literature are analysed. They are divided into empirical, critical plane and global approaches. 24 criteria are validated through 233 multiaxial fatigue tests issued also from the literature. The second part aims at taking into account the stress gradient effect within the multiaxial criteria formulation. Similarly to some recent work, the stress gradient effect is introduced within the Laboratory's criteria. These propositions are validated through combined bending-torsion tests. A proposition is made to calculate the stress gradient field from finite elements results obtained over any complex industrial structure. The third part describes the evolution of the Laboratory's fatigue life prediction method under multiaxial random loading. The first step presents a plane per plane damage accumulation. The fatigue damage is calculated and cumulated on physical planes. The second step shows the influence of the so-called counting variable on the fatigue life prediction results, and leads to a new concept: the cycle counting and the damage assessment are performed plane per plane. This procedure avoids the dependence of the choice of the counting on the life assessments. A critical plane approach criterion is required for these latter methods. This work is integrated to an industrial software called Sollife allows one to simulate the fatigue behaviour of any complex structure. The first results are in good assessment with experiments. They show the important effect of metal forming process (as stamping) and result in lots of perspectives

Revolution in iran changed the structure of economy, a free-market based industry has been changed to a government controlled industry with special problems in production and management. Utilization of scientifique decision making methods by managers abandoned mostly due to lack of experience and knowledge. Utilization of computerized systems that had a wide acceptance and rapid development during the years before the revolution, stopped due the absence of trained technicians and unenthusiastic behavior of newly government appointed managers. Although recent changes in policies and tendancy toward acquisition of technology had some positive and negative impacts on economy, still is too soon to be able to make a fair asessment of these impacts. Our study that is based on data collected from 80 managers in 23 manufacturing company shows that education and information has a great impact on the quality of decisions made by managers. The managers in this study believe that information, utilization of computerized systems and administrtive procedures simplify the process of decision making.

The aim of this research was to pin down the regional manufacturing specializations in france during a gradual declining trade barriers period. This work consists in three parts : - firstly, it was a question of justifying the regional approach by going through aggregate economic analysis which has allowed us to place the july monarchy and the second empire in their economic context; - secondly, due to a lack of regional data, as far as manufacturing exports are concerned, we used the methodology of the quantitative history in putting together every manufacturing branch into a regional and departmental matrix. So that we have used the data from the 1839-1845 census about the french provinces, the 1847-1848 census about paris and the 1837-1846 decennial tables of foreign trade. We have linked this matrix with a same size manufacturing production one which is useful in exportation analysis ; - finaly, we used the obtained outcomes through a comparison with those about 1861-1866 which displays both the modernity of the "map" of regional specializations in the mid-nineteenth century and its noteworthi stability. This comparison allowed us to identify the factors of regional specializations

A bibliographical research on nanofiltration reveals that this process has wide industrial potentiel in the field of separation of concentrated and multi-component mixtures, whereas the studies which are devoted to this field use synthetic solutions. The development of an industrial process based on nanofiltration for the treatment and valorisation of dye-house effluents is studied from economic and environmental point of view. We present the optimised process and the corresponding development on an industrial scale in which water and mineral salts are directly re-used for a new dyeing. From an ethanolic solution, the protein separation, intended for pharmaceutical application is obtained by nanofiltration. The removal of cholesterol by membrane separation represents significant progress. A model based on the Thermodynamics of Irreversible Processes and previously set up for the nanofiltration of synthetic mixtures and then extended to dye house effluents appears fairly good for the present results. It is thus possible to predict the permeate flux

De nouveaux systèmes de production flexible se développent depuis les années 1990. Ils sont basés sur des réseaux d'entreprises, très mobiles et très réactifs, et montrent des spécialisations spécifiques de leurs marchés. Ils sont surtout le fait de communautés de Chinois d'Outremer, d'Indiens, de Libanais et d'Italiens. Ces quatre types de réseau sont en fait très semblables dans leur organisation. Les entreprises concernées sont simultanément en coopération et en compétition, d'où le concept de coo-pétition. Leur compétitivité se base sur l'échange d'information et la minimisation des coûts de transaction.
A la croisée de l'économie, de la géographie, des sciences régionales et de gestion, un modèle théorique généralisé de la production en réseau explique tous ces différents réseaux d'entreprises. La confiance et la réputation sont institutionnalisées. L'intermédiation entre les acteurs a ont un rôle essentiel. Le concept de dimension de la transaction est proposé. Dans cette dimension, les entreprises optimisent leur localisation grâce la hiérarchisation des relations entre acteurs et leur communautarisme. Le modèle explique aussi la dynamique des réseaux, la résilience de leurs propriétés, l'emboîtement de leurs échelles de structuration.
Des systèmes multi-agents basés sur Visual-Basic et sur Cormas permettent de valider expérimentalement le modèle, en simulant les réseaux d'entreprises et leurs dynamiques.
