A Product-oriented Power Taxonomy Framework

Part 10: Behavioral AspectsInternational audiencePower of partners in supply chain is an essential concept in collaboration, which can influence the decisions and behaviours of the focal company. Therefore, any company has to have a good understanding on the power of partners in order to determine the possible opportunities or threats in a potential collaboration. In this paper we present a product-oriented power taxonomy obtained from the analyses on two classes of power factors: the partner-independent power factors and the partner-dependent power ones. The former are related to the product and market while the latter are intrinsic ability factors of partner such as reputation, knowledge and performance. Then we analyse the different aspects of each type of power and corresponding determinants. Furthermore, we propose a method to assess those determinants

System Engineering for dependency analysis - a Bayesian approach: application to obsolescence study

International audienceThroughout its life cycle, systems undergo several modifications in their architecture. These changes target at remaining competitive and responding quickly to new customer requirements. However, any entity change (i.e. component, function or functionality) can produce unexpected consequences, propagated throughout the whole system architecture. It is then necessary to model, predict and control them. System engineering tools and techniques allow dealing with complex systems design. That is why we have developed a novel methodology to analyze changes using a system engineering methodology called ARCADIA, developed by Thales and its associated software Capella. The obtained models allow mapping various kinds of dependencies within a system architecture. The method, presented in this paper, shows how these models are used to integrate change propagation and transform them into Bayesian networks. A set of experiments allows then to obtain insightful pieces of knowledge about the changes propagation. An illustrative case is developed with a focus of particular changes caused by obsolescence of component, function or functionality

Contribution to engineering change management in product development projects (reference models and multi-agent-based simulation)

L objectif de cette thèse est de fournir des modèles de référence, les méthodes de soutien et des outils qui simulent les change propagations dans un projet de développement de produit (PD) pour aider les prises de décision. Nous établissons d abord un cadre d analyse des changes de modéliser le contexte du change apparition et la propagation en prenant en compte les multiples domaines du projet PD simultané- ment. Dans le cadre, nous proposons les modèles conceptuels de change apparition et la propagation qui fournissent une méthode pour identifier les change et propagation et impliquent certaines caractéristiques du change propagations. S appuyant sur cela, nous vous proposons les procédures de mise en place des réseaux de propagation. Au sein du réseau, nous proposons la méthodologie de simulation de l évolution propaga- tions, puis de présenter le processus de mise en uvre des méthodologies et des modèles comme un prototype en utilisant la technologie à base multi-agents.The overall goal of this Ph.D. research is to provide reference models, support me- thods and tools that simulate change propagations in a Product Development (PD) project to assist decision-makings. We firstly establish a change analysis framework of modeling the context of change occurrence and propagation by taking into account the multiple knowledge areas of PD project simultaneously. Under the framework, we propose the conceptual models of change occurrence and change propagation that pro- vide a qualitative method to identify change and change propagation and imply some characteristics of change propagations. Relying on that, we suggest the procedures of building up the change propagation networks. Within the network, we propose the methodology of simulating change propagations and then present the process of im- plementing the methodologies and the models as a software prototype by using multi- agent based technology.BORDEAUX1-Bib.electronique (335229901) / SudocSudocFranceF

Modelling decision and data dependencies in engineer-to-order project management

[From introduction] Dependency modelling has become a useful tool for understanding and managing product development processes. In this article, we propose a framework to manage ETO projects including basically three levels of collaboration: technical, mono-project and multi-project. The framework looks at information exchange between partners forming a part of a supply chain

A taxonomy of collaboration in supply chains

The success or failure of a product design and development (PD) project depends strongly on the right contributions from its various suppliers. This is specifically the case when these suppliers do not just provide off-the-shelf items, but also contribute to the design and development of the final product. Identification, evaluation, selection, negotiation, contract signing and finally collaboration with suppliers are crucial and necessary steps towards potential success. This paper argues that a supply chain must be designed and deployed step by step while the product design is being frozen. This article presents exploratory results about a general framework called CEPS (Co-Evolution of Product design and Supply Chain) to integrate supply chain design and deployment coherently with product design. We focus on suppliers’ contribution and propose criteria to classify the collaboration situations connecting them to a given company and assess the a priori risk associate with these situations. This classification helps a company to evaluate potential risks of a PD project which integrates suppliers

Power-based supplier selection in product development projects

As stronger supplier might exert their power to influence a product development project for their own benefit, business negotiations will be more efficient if the customer has a clear understanding of its power with regards to each of its potential suppliers. This article takes the customer perspective in dealing with supplier selection and proposes a method to estimate the power of a customer versus potential suppliers. Based on an evaluation of their power, potential suppliers are then ranked. This selection procedure is illustrated with an example and evaluated against a case study taken from academic literature

Etude de la co-évolution produit/réseau de partenaires (évaluation de l'intégrabilité des partenaires potentiels pour accroître l'efficacité des projets de développement de produits)

La mise sur le marché de nouveaux produits constitue un enjeu stratégique pour les entreprises et notamment pour les PME&PMI. Les projets de développement de produits sont en règle générale bien maîtrisés localement au sein des entreprises mais sont confrontés à de réelles difficultés dès lors qu ils requièrent une étroite collaboration des partenaires. L'idée force dans cette recherche est liée au fait que pour accroître l efficacité de tout projet de développement de produits il est impératif de prendre en considération, le plus tôt possible, les contraintes liées au réseau de partenaires support à son exécution. Notre contribution s'inscrit dans le cadre de la méthodologie Co-Evolution Produit et réseau de partenaireS (CEPS) développée au sein de notre laboratoire. Cette thèse explore les dépendances entre les partenaires du réseau et propose une méthode d évaluation a priori de l intégrabilité de tout nouveau partenaire. Cette méthode est supportée par un prototype d'aide à la décision utilisable par les décideurs.AbstractBORDEAUX1-Bib.electronique (335229901) / SudocSudocFranceF
