Rivera, Gil Jose Luis. "A system approach to support a methodology for the design of formulated cosmetic products in the context of companies". Electronic Thesis or Diss., Université de Lorraine, 2022. http://docnum.univ-lorraine.fr/ulprive/DDOC_T_2022_0268_RIVERA_GIL.pdf.
Managing a new chemical product design and development project is a complex task at different levels. In addition to the technical challenges of the formulation and the definition of process conditions, design teams should also consider the requirements of the organization where the product design is performed. Therefore, the organizational dimension and its importance in chemical product design are explored in this research. Through a bibliometric literature review, it was found that chemical product design methodologies integrating the organizational context have not been thoroughly analyzed and are highly required. In this research, through a systemic analysis based on information collected in semi-structured interviews with design experts of the cosmetic sector, the characteristics of the organizational context and its effects on the product design process of that sector were studied. Additionally, information captured during those interviews was formalized in an expert knowledge base of recommendations to support the cosmetic product design process. A tool to adapt those recommendations to the design process of specific companies was proposed. The tool is applied through collaborative workshops which enable the active participation of the design team in the evaluation of the design process in order to select and implement the most suitable recommendations. Finally, the tool is applied in a real organization showing how it can be used to evaluate and improve a real design process. In that case it was found that the tool proposes adapted improvement solutions aligned to the company's value concepts, where the design team has the role of evaluator and builder of its own design methodology

Emulsion based chemical products, which belong to the category of micro-structured chemical products, have a broad range of commercial applications. Despite their importance, there is not a general methodology for their design. With the aim to contribute to the progress on this matter, this research presents a product design methodology focused on emulsion design with the following characteristics: it proposes methods for customer needs analysis, product ideas generation and selection of the best product alternative. It considers the multivariate nature of emulsion design by taking into account the multiple effects of design variables into product properties. It integrates sustainability concepts into the product design process. The methodology comprises three design stages: needs stage, ideas generation stage and ideas selection stage. In the needs stage, customer needs are first analyzed and classified according to their effect on customer satisfaction and second translated into product specifications with the aid of experts and customers. The input is customer needs, i.e., statements expressing customers’ desires about the product, and the output corresponds to product specifications, i.e., product characteristics that can be measured. To perform this stage two methods are used: Kano model and Quality Functional Deployment. In ideas generation stage, product concepts accomplishing product specifications are generated in three sub-steps: First, problem specifications are classified into a predefined group of design sub-problems. Second, each sub-problem is connected with one or more pre-defined solution strategies through a prefilled relational matrix. Third, compatible solution strategies are selected and connected to ingredients and processing conditions through a second relational matrix. As result, a set of product concepts is generated. Thisprocedure is developed by the implementation of two relational matrices proposed in this research based on emulsion science and expert knowledge. The first connects sub-problems with solution strategies and the second connects solution strategies with ingredients and processing conditions. In the selection stage, generated product concepts are evaluated according to product specifications. In addition, appropriated sustainability indicators are included to assess and rank product alternatives according to a global sustainability index. To perform this stage, a set of indicators are selected and integrated by the implementation of multi-criteria analysis methods. The application of the methodology is exposed with a case study: the design of a moisturizing cream

The design of optimal mixtures is a major challenge in many industrial sectors, especially for formulated products such as cosmetics. Due to the large number of different combinations of ingredients and their quantities, a critical issue is how to define a narrow search space using available knowledge. For this purpose, besides considering some key physicochemical properties of the final product, it is of paramount importance to take into account the performance of the product as perceived by the final consumer. Here, we have proposed a methodology to find a set of plausible formulations for emulsified cosmetic products, based on a fuzzy integral analysis of the consumer preferences and integrated into a mixed-integer optimization tool that incorporates available heuristic rules and property models. Two case studies of cosmetic emulsions were given to illustrate the methodology. In a first example using hair conditioners, the rheological, textural, and microstructural properties of nine alternative formulations manufactured at a lab scale were measured to validate the modelling of emulsified products. Then, two commercial samples of skin moisturizers were tested to identify the most relevant consumer attributes using fuzzy measures. Based on this assessment, ten computer-generated solutions with minimum ingredient costs were also manufactured and evaluated, showing that the proposed methodology could be well adapted to accelerate reformulation or benchmarking processes. Using this approach, product designers could also estimate the relevance and interactions of subjective consumer attributes and guide the design of other formulated products

Sustainable development obligate industrials to adopt a life cycle approach. The “principle of conservation” and the “extended producer responsibility” foster the development of closed-loop industrial systems, in which the product plays a central role. Products design adapted to these news systems is thus fundamental. In order to overcome the lack of methodologies in the early design phases for the evaluation of the environmental performance of the product and the benefits related to the component recovery strategies, we have developed a methodology for designing sustainable products. Based on simplified life cycle impact assessment and functional analysis, it aims at giving designers an additional design criteria for the decision process. Several propositions allow us to supply with a tool for simulating closed-loop lifecycles along with a product view supporting the products design

The paradigm of mass production and consumption based on the sale of physical products is considered because of strong competition and environmental impacts caused by this paradigm. To tackle these considerations, a service-based economy has emerged. The customer does not buy anymore a physical product, but pays for the use or for results provided by a system composed of products and services. Therefore, engineering designers must now reconsider the way they design these new systems and in particular physical objects involved in these systems. This doctoral thesis proposes a design methodology for structuring the development of these PSS from the design of the system to the detailed design of physical objects involved in the final solutions. Representations derived from the functional analysis and the establishment of operational scenarios enable the designers to describe the overall organization of the elements included into the system. This organisation is represented through the design buckles of the functional bloc diagram. Finally, the evaluation of the system from the design buckles enables engineering designers to link the parameters of physical objects and service units in order to assess that the whole system fulfil the performance expected by the customer
Abidh, Sarah. "Méthodologie d'ingénierie sensorielle pour la formulation de produits cosmétiques, application au rouge à lèvres". Thesis, Université Paris-Saclay (ComUE), 2017. http://www.theses.fr/2017SACLA023.
Lipstick is a must-have product of the cosmetics market. It is made from a complex formulation and it has multiple functionalities, among which the sensoriality is central and depends mainly on fats and oils used. Given the multiplicity of available ingredients, formulation practices are largely based on the formulators’ empirical expertise. In this industrial context, this thesis aims at setting up a reasoned formulation methodology driven by the sensory functionality. Implementing such a sensory engineering approach requires integrating knowledge of the relationships between formulation, structure and product functionalities. In order to do this, we proposed a seven-step approach, based on the realization of a simplified and realistic formula. This system allowed to structure a deductive reasoning approach concerning the role of different categories of ingredients in the sensory properties of the product. Thanks to this approach, we have shown that oils and waxes have a major role in these properties. The oils mainly affect the slipperiness, the melting quality, the oiliness, the softness, the stickiness and the presence on the lips. Waxes, on the other hand, have an influence on the opacity and the amount of lipstick deposited. This work is based on a thorough understanding of the physicochemical mechanisms at the origin of the structure of lipsticks, observed at different scales, and of the resulting properties. Finally, we validated this approach, as well as the relationships between the properties of the ingredients, the structure and the mechanical and sensory properties of lipsticks, on two concrete cases of reverse engineering

Dans le chapitre 1, nous présentons les concepts et les problèmatiques liés aux nouvelles formes et organisation de conception ainsi que l'orientation de nos travaux.
Le chapitre 2 présente les concepts liéa à l'architecture modulaire. Des principes d'organisation d'une architecture de famille de produits sont proposés.
Le chapitre 3 utilise les grammaires de graphe pour la modélisation de familles de produits. Cet outil a le double avantage de s'appuyer sur une formulation mathématique et des représentations graphiques. Son choix pour la modélisation d'une famille de produits se justifie car il permet de mettre en évidence les liaisons complexes entre les modules et les composants de la famille, ceci à travers la manipulation de la génération des variantes. Le développement et l'application du modèle sur une étude de cas industrielle démontrent le potentiel apporté par ce type de modélisation.
Le chapitre 4 contribue à une réflexion sur la complexité en conception par une approche matricielle. A partir d'une analyse structurelle des familles de produits, nous proposons des matrices de décomposition reliant les exigences fonctionnelles aux composants génériques constants, partiels et variants. A partir d'un exemple, nous montrons comment structurer les solutions technologiques associées aux fonctions sous forme de matrices diagonales par bloc. Chacun de ces blocs peut être vu comme un module d'une famille de produits et permet de regrouper les solutions technologiques associées à la fonction de ce module. Cette représentation permet de traduire le passage du fonctionnel à l'organique.

The research of alternative aircraft propulsion system is mandatory because oil dependence is too strong. The work proposed in this thesis is oriented to support electric based innovative propulsion system designers. Considering that it is important to consider entire aircraft analysis, we propose a model based, with systems engineering models, physics-based behavioral models and numerical simulation, and collaborative, because design require numerous business expertise. The objective of this approach is to build a virtual product, which means a global multidisciplinary executable model of the product under design in order to facilitate its design. A methodology is then developed, focused on the relation between the virtual product, its constitutive models and their acquisition. The methodology director wire corresponds to information research, with multidisciplinary interactions and impacts in the system, and then the application of those pieces of information to build a model of intention which allows requesting a behavioral model from experts. Finally, it is the missing link between global design driven with systems engineering and real physics based design which is implicitly at stake. To perform the methodology, a new role has been defined, the simulation architect. This thesis presents theoretically the methodology, including roles and concepts, and then this methodology is demonstrated on a helicopter based drone study-case

Industrial products currently developed are more and more complex and make use of several technologies at the same time. Moreover, design times are increasingly reduced, bringing new constraints during pre-industrialization phases. Companies have to rapid solve many problems by involving experts who have a partial knowledge of the product limited to their field of specialty. These new constraints are rarely taken into account in traditional problem solving methods. The purpose of the research work developed in this PhD thesis is quality problem solving methodology for new high technology products. By "quality problem", we mean any technical problem due to a special cause concerning the product or the process. The aim of the study is thus to propose a methodological structure adapted to this context from an organizational, sociocultural and technical point of view. The structure must be adaptable to the future evolution of this type of company: cohabitation of stabilized products and newly developed products. The objective is not to propose yet another problem solving method but rather a tunable structure in accordance with each configuration. The suggested principle is founded on a basic structure (phases and tools) modified by two assessments: the assessment of the problem profile and the assessment of its methodological state. The crossing of these two evaluations allows us to build a contextualized problem solving method with the phases that remain to be created and dedicated instrumentation for each phase. We worked on three main axes to develop this instrumentation : -selection of the methods and tools that are the most adapted to our context, improvement of these entities, analysis of the potential positive interactions between them -development of new tools -analysis of methodologies for other fields (criminology and accidentology) which have similar constraints to the studied context and their adaptation to industry. This PhD bas been carried out in the frame of a "CIFRE convention" with TRIXELL committed to the development and production of a complete family of X-ray flat panel digital detectors for the entire radiological imaging industry

The law of 11 February 2005 enables a change about the way we perceive disability. Alike for models and definitions development, the associations of People With Disabilties (PWD) keep fighting for accessibility for all of them. It’s within this context that our researches claim the benefits of innovating design integrating the needs of these users that indutrials consider as a niche market. As PWD are approximately 50 millions European people worth, can this market be still considered as a niche one? The analysis of the assistive technologies market points up a full scope for an innovation process focused on PWD needs in order to overcome existing lacks. To define the characteristics and the needs of these target users requires to understand and characterize what creates a disability situation. Some PWD specific needs are already at the root of inventions and technological advances used by a majority of people today (e. G. Remote control, mixer taps, voice recognition, etc. ). We’ll try to demonstrate through experiments leaded in partnership with the French Neuromuscular Diseases Association that knowledge of target users needs can be considered as a potential source of innovation for everybody

This thesis focuses on the information process at work in the financial market world. We analyse information seeking practices within the activities of development and design of financial products by coupling the information seeking behavior theories together with the financial theories. We thus describe the information resources and the information seeking and use processes of professional practitioners. We then develop a formalized and rigorous tool entitled " A Mark-up Language for Financial Products " or MLFP, a XML - based markup language. That tool enables us to specify the most important items used in the course of these activities. That digital tool can be used both by the financial products manager and the designer in order to describe or update financial products while having precise and reliable informations on their direct competitive environment at their disposal

The purpose of this study is to model an ‘enhanced design' methodology applied to the conception of an innovative product in a SME environment. This approach includes C-K theory in a context of disruptive innovation.In general, the industrial design process consists of four major steps:1/ the ego-design phase, where the designer conceptualizes a user need,2/ the techno-design phase, where designer and engineer find solutions to materialize the concept,3/ the eco-design phase, where social actors involved authorize it and then4/ the ergo-design phase, where the user adopt the final product.A methodological reflection leads to the modeling of the innovative ‘enhanced design' reasoning (where major actors are replaced by a bunch of various stakeholders).The specific SME's case was successful. Using the model, the enhanced design project management was efficient. But some more complex application cases would help secure it. Using this approach, with appropriate information, should guide the SME design project manager in the general radical innovation process

Today, quality control is essential to satisfy customer requirements. Although there are different methods and tools specially developed to manage the quality of systems or processes within companies, it is difficult to establish the link between management of a company's many processes and product quality for a system in service. In this context, a CIFRE thesis was conducted within MBDA, a company that designs, develops and produces weapons systems. The problem of this thesis is to develop a methodology allowing to produce a definition of the product quality of a complex system which is valid throughout its life cycle, and allowing the construction of models to predict the product quality in use during development and production. Our contribution consists of a two-phase methodology. The first phase makes it possible to establish a definition of the product quality of complex systems from the customer's point of view adapted to the industrial context by defining several product quality factors that are relevant for all phases of the systems life cycle. The second phase builds product quality prediction models that provide a life-cycle quality assessment of the systems and a forecast of what the quality will be in use. Both phases of the methodology rely on the use of experts' judgement to enable its use without a significant amount of data. The models built have been tested for systems developed by MBDA

The purpose of this research is to obtain the appraisal and feelings of customers, translated by product attributes, about an innovative product during its design process, i.e. without all the sensory and functional features available like for a finished product. Two main goals are to inquire the customers’ ways of thinking early in the design process and to compare several products themselves or the same product at different stages in the process. The objective is to help the designers and managers decision.To meet these goals, we realized and checked several methodological approaches:• To offset the lack of sensory and functional features of an innovation’s prototype, we created a “sensorial brochure”,• To facilitate the product assessments’ comparison, we created a standard questionnaire to inquire customers. In fact, with a bibliographic research of the hedonic and pragmatic attributes involved in the assessment of a product, we created a list of statements,• To validate these methodological tools, we realized a comparative approach at several milestones or stages of the design process. In total, we realized six customers’ assessments at different stages of the design process with 302 respondents.Then we studied and compared the assessments’ results. The aim is to validate the construction of the sensorial brochure and the questionnaire and to conclude from the innovation’s prototype assessments at different stages of the design process. The questionnaire needs to be improved but it has already permitted to inquire the customers on their hedonic and pragmatic attributes in front of a product. The sensorial brochure helps customers to imagine the future product

Nzetchou, Stéphane. "Méthodologie d'enrichissement sémantique de la CAO dans un environnement de continuité numérique". Thesis, Compiègne, 2021. http://www.theses.fr/2021COMP2642.
The digital transition in the manufacturing industry is characterised by a three or even four-decade liability. Some CAO models or digital mock-ups accumulated du ring this period are frozen, i.e. 3D models without a construction tree, which are characterised by missing geometries, due to software changes or versions of 3D formats that have not been updated Reverse engineering activities of CAO models, aiming at obtaining semantically rich 3D models, i.e. parametric and modifiable, made up of construction operations, carrying attributes and metadata, with geometric ru les and constraints, etc., thanks to the use of engineering tools such as CATIA for example, or by approaches based on point clouds coming from a scan for example. But, this is still not satisfactory, because at the end of the reverse engineering activities, we often obtain a solid with a weak semantic representation or an absent construction tree. This leads us to propose in the framework of this thesis work, a methodology for managing information linked to CAO models in order to integrate expert information that we call semantic into these CAO models. The frozen CAO models handled are usually in low-level formats such as STL, IGES or STEP AP203. They are used as input data for our methodology and they can be associated with product definition data, such as a product drawing or documents. The processing of CAO models requires a solution that is able to_manage the digital models and the information they couId possibly integrate. And also the incompleteness of some CAO models that is linked to the 3D format or to the limit of the technology used to obtain the CAO model (e.g. software li mit, 3D format for geometric representation only and that does not support a representation of the construction tree or that cannot graphically represent geometric dimensions and tolerances, etc.). Finally, the relevance of integrated information into CAO model, of a non-geometric nature, during the semantic overlay phase should make it possible, in certain cases, to produce parameterised CAO models, specific to the activity of the application domain. The state of the art, concerning the information representation contained in CAO model and the management of this information, makes it possible to identify techniques and approaches that help the semantic enrichment of CAO models at various levels of granularity. This thesis proposes a methodology named Vaquero For CAO Semantic Enrichment (VFCSE), which is made of three step access, identification and annotation. The aim of this methodology is to integrate missing and standardised information of a non-geometric nature, such as product specifications, tolerances, geometric dimensions, etc., into frozen CAO models. This information will be derived from user needs working on the CAO model and will corne from a semantically rich standard in order to be useful for many operations related to the product life cycle. The enrichment, thanks to this semantically rich standard, will allow for a perpetuation of the information and an efficient reuse of CAO model information. ln order to do this, a CAO model is retrieved from a PDM (Product Data Management) thanks to a user request. lt is visualised in a CAO viewer supporting STL, IGES and STEP AP203 formats. Then, follows a step of identifying components of CAO model. These components can be parts or assemblies. The identified components are annotated based on the STEP AP242 format, which represents the semantically rich standard. These annotations are stored in a standardised ontology, which serves as a minimal basis for carrying all the semantics to be integrated into the CAO mode in order to make the CAO model durable and reusable. The scientific contribution of this work is mainly based on the possibility of reverse engineering by using ontologies to annotate 3D models, according to user needs who has the CAO model at his disposal

The cosmetic industry is governed by consumers’ expectations for natural products with proven efficacy, to which formulators reply by the integration of natural and eco-designed actives in those products. This PhD work focussed on the development of such innovative cosmetic actives favouring wound healing from Mediterranean plant materials. The biological activities of a hundred natural extracts from 77 raw materials were screened using in vitro assays (antioxidant, anti-inflammatory and anti-age -anti-hyaluronidase, anti-collagenase and anti-elastase activities-activities). Among them, a total of 28 plants turned out to be especially interesting, and three were selected in this work frame. The germander (Teucrium lucidum L.) was selected because its Mediterranean endemicity, and as its phytochemistry was only cursorily studied. The downy oak (Quercus pubescens Willd.) and the Brignoles plum tree (Prunus domestica L.) were selected because they are regional agricultural by-products, which are therefore very interesting to valorise. This study focussed on the phytochemical characterization of germander extracts obtained by maceration of aerial parts of germander and promote wound healing. Eight main compounds were isolated and identified by NMR; only three of them were previously described in the Teucrium gender. Further five compounds were also characterized; none of them has previously been described in T. lucidum. Furthermore, the study consisted in the design of the methodology of development of liquid and solid natural cosmetic ingredients, from the supply of raw materials to the ingredients’ integration in finished cosmetic products. This methodology was illustrated by the study of the two agricultural by-products selected beforehand, namely the downy oak and the Brignoles plum tree. It allowed to identify the steps to adapt to each plant material according to its phytochemical composition

Future products face dramatically challenges to meet continuously moving customers requirements, differ from competitors and be friendly with the environment in a global sustainability where company profits are there as well. It leads to re-organize company processes, mainly the design and development process, and the tools and methods to respond to this demand. This PhD project deals with developing a new integrated design methodology to be applied on a high level and globalized consumer goods industry. It has been developed for and applied on the leather goods industry in Thailand. The proposed design methodology leans on an emotional design approach to understand customers and make them active in the design process on one hand and on the other hand on expressing the company identity as a main driver of the engineering design process. Consequently, the methodology integers customers satisfaction, brand benefits and the optimized engineering supports. As a result of the study, three tools to support the methodology were developed: the customer-oriented matrix to be in phase with customers; the design support matrix to guide designers in creating brand identity oriented new products; the manufacturing matrix to embed reliability and costs. The tools and methods developed were implemented and tested on an original case in a Thai leather goods manufacturer

Today the consideration of environmental issues is essential in relation to companies' sustainability policy. The literature review reveals that ecodesign is not an easy viewpoint to integrate due to its specificities. Despite the great number of existing tools and methods, companies still encounter difficulties for implementing ecodesign in their design process.This research work aims at providing a combined solution including a methodology supported by a software platform. The methodology guides the design team through a series of steps to realize in the design process. And, to manage ecodesign activities, we defined the structure of a software platform gathering the necessary tools for the design team: tools for the design of the product life cycle, an assessment tool for the cost and the environmental impacts, a guidance tool based on ecodesign rules and case studies, a monitoring tool for the project indicators, and databases in relation with the model of the product and its life cycle.The results of two industrial experiments demonstrate the validity of our proposition. However, a limit of the platform has been identified during the second case study. A third experiment has therefore been realised during a workshop in an international conference to tackle this point
Audoux, Kévin. "Proposition d'un processus d'évaluation multidomaine pour améliorer la conception de produit". Thesis, Paris, ENSAM, 2019. http://www.theses.fr/2019ENAM0025/document.
Industrial competition is driving companies to develop new innovative products. In addition, industrial companies are increasingly subject to constraints from the various actors in the design process (manufacturers, users) or linked to changes in their environment (regulations, technologies). It is therefore necessary for them to adapt their design activities and more particularly the evaluation steps so that the products developed correspond to the multiple requirements of all stakeholders. These constraints result in the integration of new domains or the evolution of existing domains into the design process.In this context, the objective of this thesis work is to formalize and provide methods for multidomain evaluation in the design process. This manuscript therefore addresses the following question: "How can evaluation phases in a multidomain design process help to increase the performance of intermediate representations? ». To this end, we propose a methodology to improve the evaluation process by creating a multidomain evaluation tool and formalizing the steps of the evaluation process to provide improvement methods adapted to the areas concerned by the product to be designed. Experiments are being carried out to validate their contribution to the design process, focusing in particular on three areas: innovation, taking into account environmental impacts and additive manufacturing. These experiments made it possible to validate the methodology for creating an evaluation tool and the contribution of the improvement steps

In recent years, the European textile industry and textiles imports have had to comply with an increasing number of environmental policies. Emissions from industrial installations have been subject to EU-wide legislation for over 10 years: the IPPC Directive, the European Pollutant Release and Transfer Register (E-PRTR)… Since 2007, European textile producers also have to comply with a substantial number of obligations under REACH. Furthermore, in France environmental labelling for certain convenience goods (including textile products) might become mandatory in 2020. In parallel, national awareness appeared on the necessity of designing consumer products with limited use of natural resources and decreased the environmental impacts. Eco-design involves the implementation of new materials and new processes. Life Cycle Assessment, LCA, is a tool that enables the assessment of environmental impacts. This thesis was initiated by Bureau Veritas CODDE Company and the GEMTEX laboratory, following on the identification of a significant need for the development of LCA data and methods in the textile sector. This is because the existing methods and tools are not suitable for the environmental impact assessment of textile products since the textile sector presents specific constraining characteristics. These tools should enable designers, manufacturers and retailers to perform LCA on their products
Wang, Lei. "Les pratiques et les représentations des soins du corps en Chine". Thesis, Paris 5, 2014. http://www.theses.fr/2014PA05H001/document.
This work questions the constraints and triggers of cosmetic practices in China and Chinese people body conception. It consists in, firstly, studying diachronically the effects of generations that are influenced by cosmetic products on the market and the social norms of body care at different times. Secondly, the effects of life cycle are analyzed as triggers, levers, important to body care and makeup practices. Finally, synchronously, it aims to follow the itinerary of cosmetics in wealthy women families: from the information before the purchase decision, mobility, acquisition, use, storage to the fate of the product. In the next step, the survey with dermatologists of traditional Chinese medicine and modern Western medicine help to check if dermatologists are prescribers of cosmetics in China and dig further analyze the conception of the body and disease among the doctors applying traditional Chinese medicine. This work allows us to understand that Chinese women reinterpret the modern Western cosmetics by their Chinese body conception in everyday life
Zhang, Qiang. "Process modeling of innovative design using systems engineering". Thesis, Strasbourg, 2014. http://www.theses.fr/2014STRAD007/document.
We develop a series of process models to comprehensively describe and effectively manage innovative design in order to achieve adequate balance between innovation and control, following the design research methodology (DRM). Firstly, we introduce a descriptive model of innovative design. This model reflects the actual process and pattern of innovative design, locates innovation opportunities in the process and supports a systematic perspective whose focus is the external and internal factors affecting the success of innovative design. Secondly, we perform an empirical study to investigate how control and flexibility can be balanced to manage uncertainty in innovative design. After identifying project practices that cope with these uncertainties in terms of control and flexibility, a case-study sample based on five innovative design projects from an automotive company is analyzed and shows that control and flexibility can coexist. Based on the managerial insights of the empirical study, we develop the procedural process model and the activity-based adaptive model of innovative design. The former one provides the conceptual framework to balance innovation and control by the process structuration at the project-level and the integration of flexible practices at the operation-level. The latter model considers innovative design as a complex adaptive system, and thereby proposes the method of process design that dynamically constructs the process architecture of innovative design. Finally, the two models are verified by supporting a number of process analysis and simulation within a series of innovative design projects

A current challenge for food chemists consists in developing safe yet appealing food. This is particularly difficult in thermally-treated foods, like baked products, since a great number of compounds may be produced during heating. While some of these are of health concern, others contribute to other key aspects of quality, such as aroma or color, revealing the need of considering reactivity into food quality design. This work deals with the effects of formulation and baking conditions on the generation of furan, a heatinduced contaminant, and furfural, contributing typical aroma to sponge cake. Moreover, a holistic approach was adopted, covering volatile generation, physical properties, sensory evaluation and consumer tests, both for further understanding reactivity and optimizing product quality. This work is certainly an important step towards the development of novel strategies for qualitydriven design of heat-treated food
Plo, Laureline. "Proposition d'une démarche de déploiement d’une solution PLM dans des entreprises "libérées" : cas du biscuitier POULT". Thesis, Bordeaux, 2018. http://www.theses.fr/2018BORD0111/document.
Deployment of a PLM solution in companies of the agri-food sector improves management of their products and projects of development. However, this type of project remains structuring for the organizations and can sometimes be badly perceived in a freedom-form company, with the non-hierarchized organizational structure and with actors feel to have a great autonomy in their activities. This thesis presents an approach to support PLM solution deployment projects in such companies. After describing all the phases and activities of our approach, we highlight the importance of the human relationship, the exchange and the "explanation" with all the actors from the start of the deployment project to favor acceptance of the PLM software tool. This leads us to evolve traditional deployment approaches, especially during the analysis of needs phase prior to the implementation of a PLM solution. Our contribution is placed in a dynamic of research of improvement of process, product and organization models to implement a PLM in a freedom-form company. This approach was built and implemented as part of a collaboration with the Poult biscuit industrial group, results of this real case study are also presented in this manuscript
