La personnalisation de masse est une configuration de l'offre produit, du système de production et de la chaîne de valeur, qui permet la satisfaction (mesurée par la valeur perçue) des besoins individuels des clients et celle des autres parties bénéficiaires (e.g. l'entreprise, les fournisseurs, etc.). Les recherches menées ont permis d'obtenir une...

The survival of a company nowadays depends on answering to a customer-driven economy, and therefore relies on the performance of its entire network of partners. Competition is no longer among companies nor among supply chains, but rather between networks of companies which form a value network. Thus, the need has arisen to analyse the performance o...

The assessment of organizational capabilities becomes a great challenge in extended and flexible organizations. This assessment is generally independent from the evaluation of operational results and could become isolated from the rest of the global performance system and face validity issues. This paper aims at creating new control loops by propos...

This paper studies the problems of knowledge transfer and operational reuse in distributed organisations. These issues can be summarised by the inherent contradiction between "detecting and boosting local innovation" (so that group learns from its entities) and "coding, standardising and transferring good practices and organisational capabilities"...

This paper discusses the use of knowledge sharing and communities of practices so as to make possible and support collaboration between units inside a same organization. It proposes a framework and some tools so that an intra-organizational interoperability capability emerges without “special efforts”.

This paper studies organizational learning issues in groups, which can be summarized by the inherent contradiction between «boosting and detecting local innovation» (so that group learns from its entities) and «coding, standardizing and transferring good practices and organizational capabilities» (so as group teaches its entities). This article des...

Nowadays performance is tending towards the control of the potential of achievement of organization. The systems for performance evaluation and management are therefore focusing on the control of organizational learning processes, by identifying organizational capabilities and managing their development. To this end, a new method has appeared, the...

This paper aims at examining how a change in organizational structure affects a firm performance. In a competitive environment, firms have to "share" customers who want a given product/service. Since integration impacts prices, which is a major choice criterion for customers, it thus impacts sales and profits. A model is proposed that integrates pr...

From innovation management have emerged some methods and tools supporting it. Some are helping innovative design; some others are focusing on the propagation of a culture of innovation. However, it is also necessary to manage the reuse of ideas and concepts generated by these two sets of methods, by structuring knowledge, information and people dur...

This paper discusses organizational interoperability issues in through the study of two cases. Then it presents a framework which can help to design and manage this interoperability, by driving the development of “organizational capabilities”.

Améliorer les performances des entreprises est un objectif que beaucoup cherchent à atteindre. Pour y arriver, il faut déjà être capable : de déterminer la meilleure structure pour l'entreprise, de formaliser son système d'information et de pouvoir maîtriser les processus liés à la chaîne de valeur et au cycle de vie des produits. A cela il faut aj...

La performance est aujourd'hui vue comme la ma�trise du potentiel de r�alisation de l'organisation. Il devient donc n�cessaire d'adapter les outils de pilotage pour qu'ils int�grent les probl�matiques du d�veloppement du progr�s fonctionnel et de la ma�trise du savoir agir des entit�s de l'entreprise. Ce savoir agir, r�pondant aussi au nom de capac...

Knowledge management is one of the critical issues for the improvement of enterprise performances. Different methods exist for extracting and formalizing knowledge in order to create knowledge-based applications. Most of integrated design and manufacturing technological processes are more or less based on knowledge that has been translated into mod...

In an assemble-to-order context, the choice of a modular design is of paramount importance. The selection of the semi-finished products that would be kept in stock, indeed impacts the whole supply chain (storage, transport, production, etc.). In this article, this lever is used to minimize, for a given number of stocked modules, the mean final asse...

This paper is a state of the art review of trends, theories and practices in production and logistic networks and the evaluation of supply chains. The paper outlines the progression of concepts from supply chains to the definition of production networks, summarises the trends for virtual companies and outlines recent research in logistics. The use...

This article is organized as follows: industrial context is summarized in Section 2, in Section 3 we define our goal and methodology. Results are given in Section 4

Communities of Practices are particular and identified knowledge networks involved in a new global, virtual and digital framework. The study of their specific characteristics, the Legitimate Peripheral Participation and the duality Reification/Participation, provide the necessary background to understand and formalize the barriers and the limits in...

The question of plant layout is central in a manufacturing process. This question becomes even more important in a mass customization context, when a large product diversity has to be managed. The manufacturing process, and specifically the plant layout, has to be designed taking into account this characteristic. When all products are similar, manu...

The assemble-to-order (ATO) production strategy considers a tradeoff between the size of a product portfolio and the assembly lead time. The concept of modular design is often used in support of the ATO strategy. Modular design impacts the assembly of products and the supply chain, in particular, the storage, transport, and production are affected...

The assemble-to-order strategy delays the final assembly operations of a product until a customer order is received. The modules used in the final assembly operation result in a large product diversity. This production strategy reduces the customer waiting time for the product. As the lead-time is short, any product rework may violate the delivery...

The process of real estate credit attribution is complex. The risk of accepting a credit for a customer that will not pay back has to be assessed and evaluate carefully. This process requires several steps, including the search for information within different tasks and banking organisations. Nevertheless, the evolution of real estate sector induce...

An assemble to order policy considers a trade-off between the size of product portfolio and assembly lead time. The concept of modular design is often used to implement the assemble to order policy. Modular design impacts assembly of products and the supply chain. In particular, storage, transportation and production are affected by the selected mo...

This PhD thesis addresses the problem of the set-up of a stock policy adapted to a huge diversity context. We propose to include the notion of information levels into the classical question of design and inventory management. When product diversity enlarges, choosing an Assemble To Order policy offers a good compromise between product portfolio siz...

Engineering Changes (EC) implementation in product definition and at all stages of the product life cycle cannot be avoided when struggling for innovation and maintaining the product in accordance with the contractually agreed specifications. These "micro" design actions usually provide large profits on both product and processes and allow a flexib...

An assemble-to-order policy delays the final assembly operations of a product until a customer order is received. The quality of the final product is determined by the quality of the assembly operations. The data- mining approach presented in this paper uses information extracted from production history to determine the sequence of assemblies that...
