A conceptual model for SMEs mechatronics supply chain.

17International audienceNowadays, in order to meet the demands of the global dynamic market and eliminate its disturbances, the supply chain and its integration across different organizations has become a competitive business advantage along the production processes. In particular, the mechatronic industry is very sensitive to these requirements. Our research deals with modelling the supply chain in order to manage and implement a simulation platform. Basically, we develop a modelling solution for an industrial environment composed of mechatronic Small and Medium Enterprises located in Savoie (France). The study is based on elements from real applications and the SMEs network organization. An analysis of the domain helped us to develop concepts and a modelling approach adapted to these companies. In this work, we present the area studied, the methodology used to construct the conceptual model of the supply chain, its structure and management rules. Then, we present the model obtained. Finally, we apply this conceptual model to a case study

Une Approche Agent pour Modéliser la Chaîne Logistique dans un Contexte de PME Mécatronique

International audienceFace aux exigences du marché et à ses fréquentes mutations, l'intégration des différents acteurs dans la chaîne logistique est devenue un atout concurrentiel quel que soit le domaine de production, qu'il soit de biens ou de services. Le domaine de la mécatronique n'est pas épargné par ces exigences. Les travaux de recherche présentés dans cet article s'inscrivent dans ce domaine puisqu'ils s'orientent vers la recherche d'une solution pour un tissu industriel composé particulièrement de PME situées dans les pays de Savoie. Dans cet article, nous mettons en œuvre des recherches issues de deux domaines différents. Le premier se focalise sur l'étude des maillons et de l'organisation des PME dans la chaîne logistique. L'analyse qui en découle nous permet d'identifier et de modéliser les concepts relatifs à notre domaine de recherche. Le second concerne le processus de développement logiciel basé sur l'approche multiagent qui offre une modélisation structurée et réutilisable des concepts de la chaîne logistique. Abstract - In order to meet global dynamic market and its perturbations, the supply chain and its integration across the different organizations has become a competitive business advantage along the production processes. In particular, the mechatronic industry is very sensitive to these requirements. Our research deals with a supply chain modelling solution for an industrial environment composed of Small and Medium mechatronic Enterprises located in Savoy. In this paper, we combine two research scopes. The first one focuses on the study of elements and SME organization in the supply chain. The analysis allows us to identify and model the research domain concepts. The second one outlines the development process based on an agent modelling approach which offers an easy and reusable modelling of supply chain concepts

Multiagent Decision Making for SME Supply Chain Simulation

International audienceTo tackle the complexity and heterogeneity of the networks that integrate Mechatronic SMEs, this paper describes a modelling and simulation solution based on multiagent system and ArchMDE (Architecture Model Drive Engineering) methodology for supply chain agentification. This research work outlines two main results: conceptualisation and modelling. The first one deals with the identification and concepts definition of the different entities moving and acting into the multiagent and supply chain systems. The second one discusses the agent approach providing a framework naturally oriented to model supply chain concepts and their dynamic behavior

A Multiagent System for Production Synchronization in SME Mecatronics Supply Chain

International audienceWe present in this paper the application of multiagent system (MAS) for modelling and simulation of the dynamic structure and behaviour of the supply chain in SMEs mechatronic context in Savoie. First, a short literature overview describes the context and the contribution of multiagent modelling for SMEs integration. In the rest of the paper, the supply chain concepts and their agentification are presented. On the basis of this correspondence, we propose a synchronization protocol for the operational system (production flow and resources)

A multi-agent knowledge model for SMEs mechatronic supply chains.

19International audienceThe main concern of this research work is to analyse and model supply chains (SCs) in a particular context which is that of small and medium enterprises (SMEs) in the field of mechatronic. The study is based on the analysis of the organisational features, the actors' behaviour, and performance considerations. The development of the model relies on an iterative framework that progressively integrates different aspects into the model. This framework is the ArchMDE process, which is based on MDE (Model Driven Engineering). A major feature of this work lies in its contribution to two different areas of research. The first contribution of the work is to propose a generic metamodel for SCs. Based on a literature review, an incremental framework is proposed for the modelling of SCs in terms of concepts, structure and relationships. The application of the framework to the studied context is described and its result is a domain-metamodel for SCs. The second contribution of this work lies in the formalisation of the dynamic behaviour of the concepts in the metamodel. This formalisation is based on the multi-agent approach. An agentification of the metamodel is thus drawn, thanks to the natural links between multiagent theory and SC reality. This step leads to an agentified-domain-metamodel which also includes the monitoring of the SC and synchronisation protocols. By adding relationships and dynamic behavior aspects, we obtain a metamodel of the domain that can be implemented, with its static and dynamic aspects. To validate this model, an industrial case study is detailed and has been instantiated and encoded in JAVA

Modélisation pour la simulation de la chaîne logistique globale dans un environnement de production PME mécatroniques

The main concern of this PhD is to study (analyse) and model supply chains (SCs) in a particular context which is small and medium enterprises (SME) in the field of mechatronic. The study (research) is based on analyzing the organisational features, actors' behaviours, and performance considerations. The development of the model relies on an iterative framework that progressively integrates different aspects into the model. This framework is the ArchMDE process, which is based on MDE (Model Driven Engineering). A major feature of this work lies its contribution to two different areas of research. The first contribution of the work is to propose a generic metamodel for SCs. From a literature review, an incremental framework is proposed for the modelling of SC in terms of concepts, structure and relationships. The application of the framework to the studied context is described and its result is a domain-metamodel for SCs. The second contribution of this work lies in the formalisation of the dynamic behaviour of the concepts in the metamodel. This formalisation is based on the multi-agent approach.

Le développement de la solution de modélisation s'inscrit dans une démarche de raffinement itératif et d'intégration progressive de modèles. Le cadre de cette démarche constitue le fondement du processus de développement adopté « ArchMDE » basé sur l'Ingénierie Dirigée par les Modèles (IDM). Par conséquent, les travaux de cette recherche sont caractérisés par une contribution double. Dans la première contribution, il s'agit de la proposition d'un métamodèle générique de la chaîne logistique. En puisant dans la littérature nous avons proposé une méthodologie de conceptualisation incrémentale et générique qui permet la génération d'un modèle conceptuel de la structure d'une chaîne logistique ainsi que les relations entre ses différentes entités. L'application de cette démarche a donné lieu à la construction d'un métamodèle décrivant le champ d'application étudié (PME mécatroniques). La seconde contribution permet de formaliser le comportement dynamique des concepts générés lors de la première étape en adoptant le paradigme multi-agent. Ainsi, nous avons proposé une agentification du métamodèle du domaine en se basant sur l'analogie naturelle entre la chaîne logistique et le système multi-agent. Cette agentification a donné lieu à un métamodèle du domaine agentifié avec une mise en place des protocoles d'interaction visant à synchroniser et piloter la chaîne logistique. L'étude des relations et du comportement dynamique des différents concepts a permis d'aboutir à un métamodèle d'implémentation qui exprime à la fois les deux vues statique et dynamique du domaine d'application. Ce dernier artefact a fait l'objet d'une instanciation et d'une implémentation d'un cas industriel réel dans un environnement JAVA

A Generic Knowledge Model for SME Supply Chain Based on Multiagent Paradigm

23 pagesInternational audienceThis chapter is dedicated to the generation of an agentified knowledge model for modeling and simulation of the supply chain in Small and Medium Enterprises (SME) context. For this purpose, the organization of this work is directed by the ArchMDE development process which is founded on Model Driving Engineering (MDE). The fundamental contributions concern two research areas. The first one concerning the industrial engineering scope, proposes a generic domain meta-model (i.e. supply chain integrating SME) identifying the functional concepts and their properties. The second one considering the computer engineering scope, highlights all steps necessary to integrate the dynamic behaviour into the domain meta-model built according to the multi-agent technology. In this perspective, this chapter describes the outcome of these artefacts from the study of the domain through the agentification process, to the implementation of the knowledge model

Selective catalytic reduction of NO by NH3 over copper-hydroxyapatite catalysts: effect of the increase of the specific surface area of the support

International audienceThe influence of the increase of the specific surface area of the support Ca-HAp on the dispersion of copper species and their activity in the NO-SCR by NH3 has been studied. The copper ion exchange does not alter the Ca-HAp structure whatever the copper concentration. The increase of the specific surface area of the support changed the dispersion and the reducibility of copper species. The high NO conversion in the whole temperature range for the catalyst with the lowest specific surface area (35 m2/g) was related to the highly dispersed CuO particles that are easily reduced. Nevertheless, the increase of the specific surface area of the support (76 m2/g), induces an increase of the size of CuO particles that become less active in NO-SCR by NH3. The addition of 2.5 % of H2O to the reaction gas feed strongly affects the NO conversion in the whole temperature range. This deactivation can be related to the change of the nature of copper species rather than to the destruction of the Ca-HAp structure
