Développement d'indicateurs de performance pour l'évaluation du processus de conception – Approche basée sur l'analyse des itérations en conception

Dans le contexte industriel d'aujourd'hui, le pilotage du processus de conception est une charge difficile pour les chefs de projet. Ce processus est dynamique et complexe. Il est aussi soumis aux influences internes et externes. A cause de ses caractéristiques et à cause des influences auxquelles il est soumis, son déroulement est souvent perturbé. Les perturbations génèrent des itérations dans le processus de conception. Pour pouvoir piloter le processus de conception, les chefs du projet ont besoin de connaître ses caractéristiques et les limites de son déroulement normal. Dans cet article nous présentons une démarche de développement d'indicateurs de performance nécessaires à l'évaluation du processus de conception, prenant en compte les itérations des tâches de conception. L'objectif d'évaluation est double : 1) améliorer en continu les performances du processus de conception ou valider le processus étudié et 2) collecter les données nécessaires pour améliorer un nouveau processus. La démarche proposée est basée sur l'étude et l'analyse des itérations sur trois expériences de conception

Modélisation et évaluation d'organisations industrielles en ingénierie simultanée (approche méthodologique pour la mise en oeuvre de solutions de conception intégrée)

Le milieu industriel d'aujourd'hui subit des contraintes économiques et technologiques de plus en plus sévères. La mondialisation des marchés a rendu très forte la compétition sur le coût, le délai et la qualité. Pour faire face à cette situation, les entreprises manufacturières doivent être en évolution constante afin de reconsidérer leurs méthodes d'organisation du travail, notamment les méthodes de développement de leurs produits. Le travail présenté dans cette thèse s'inscrit dans ce contexte et à pour objectif de développer une méthodologie permettant de modèliser le cycle de développement de produit (CDP) et d'en évaluer les performances. Nous proposons le modèle TMCDP (Modèle technique et de managelent du CDP) qui à la particularité d'intégrer, dans une représentation homogène et cohérente, les aspects techniques du CDP et ceux des modes de gestion sous-jacents ; le CDP est vu comme un réseau d'activités dont on analyse la réactivité face aux aléas et perturbations. Le modèle est engagé pour appréhender les situations à analyser et développer des solutions de développement de produit dans un contexte d'ingénierie simultanée. Il est étendu pour permettre une quantification des situations considérées par des développements de simulation.BORDEAUX1-BU Sciences-Talence (335222101) / SudocTARBES-ENIT (654402301) / SudocAIX-EN-PROVENCE-Arts et Metiers (130012302) / SudocCACHAN-IUT (940162201) / SudocCLERMONT FD-IFMA (630142301) / SudocSudocFranceF

Product development process improvement: A review of Design Structure Matrix methods

Iteration is an important characteristic of the design process. The Design Structure Matrix (DSM) is a powerful method allowing modelling, analysis, and optimisation of iterations in the design process. Boosted by the concepts of concurrent engineering, it has been widely developed during the decades by researchers from both academia and industry. The objective of this paper is to provide a review of different DSM based techniques used to improve the performance of the product development process

Lean engineering in the design process: An industrial application

The objective of this paper is to present a methodology used to streamline the product development process by introducing Lean Engineering concepts. We are interested specifically in routine design which represents in some companies more than 80% of the design activity. A project management model was developed and implemented in a PLM tool. This allows faster initiation of projects in which project planning is automatically performed. Hence, non-added value tasks in project planning were identified and reduced

A coordinated scheduling of delivery and inventory in a multi-location hospital supplied with a central pharmacy

In today’s manufacturing outlook, coordinated scheduling of delivery and inventory represents a leading leverage to enhance the competitiveness of firms which aims to address the new challenge coming from scheduling problems. Though in the last decades this kind of issue has been extensively approached in the literature, a set of constraints and compulsory dispositions strongly increases the complexity of the considered problem. Actors of the pharmaceutical supply chain have to meet various global regulatory requirements while handling, storing and distributing environmentally sensitive products. The studied problem in this paper focuses on a real-case scheduling problem in a multi-location hospital supplied with a central pharmacy. The objective of this work is to find a coordinated production and delivery schedule such that the sum of delivery and inventory costs is minimized. A mixed-integer programming formulation is first detailed to consider the problem under study. Then, a branch-and-bound algorithm is proposed as an exact method and a dedicated heuristic algorithm is highlighted to solve the problem. At last, the experimental results show the efficiency of the proposed solving methods, based on the two following criteria: solution quality and processing time
