The objectives of this article are twofold. First, we seek to contribute to the understanding of obsolescence through two conceptual models. They enable, among others, to link the points of view of the external and internal actors of the system. This mapping is fundamental when it comes to solve the re-design problems posed by some obsolescence issues. The obsolescence management process consists of Prepare, Identify, Assess, Analyze, and Implement. The second objective is to offer two support tools for the Identify and Assess phases: House of Obsolescence and System Obsolescence Exposure Analysis. The first allows to map the changes, desired or imposed, by external actors to the critical components and functions of the system architecture. These latter are then analyzed using the second tool whose objective is to assign an obsolescence exposure index to the identified obsolescence issues in order to prioritize them for solution determination during the analysis phase. The tools make extensive use of the modeled system knowledge through the application of System Engineering. The application of the tools is then illustrated through a case study

We study the different aspects of co-design and informal networks, and then we introduce an approach for analysing the actors' network structuring. We apply it through a worldwide company producing energy. This industrial case explores the structuring then the management of actors' networks involved in a process of constructing a technical and financial proposal to potential customers. Dimensions such as project organisational structure, concurrent engineering techniques, groupware-like and knowledge-based systems support are analysed. Our aim is to develop a global framework for supporting management of co-design networks integrating these dimensions. A system divided into two main components is proposed: the first one to characterize networks and to model these networks, by integrating the mechanisms of quantification and qualification, and indicators. The second relates to the exploitation. The objective is twofold: first allowing an actor to manage its own list of external or internal collaborators with criteria of characterization; and second allowing a project manager to define a series of target indicators in order to select actors to imply into a new project.

It allows the strong companies to win more than others, or more broadly, to coerce others to do what they would not otherwise do. Power can seriously affect the confidence and commitment between parties. This paper aims to analyze the power concept in inter-organizational relationships. We discuss some formal results modeling power and the set of elements and properties necessary to understand these concepts. We also proposed a "power generation process" that allows to describe how power is developed in a relationship according to dependency. As far as we were able to browse the scientific literature, these are the first attempts to suggest a robust foundation of the power theory.

These strategic tools require huge efforts for their choice, implementation, running and evolution. Today these Tools become the key support of the enterprises competitiveness. This article highlights some consequences of implementation of a new software and discusses practical benefits of using Enterprise Modelling approaches in this kind of global projects.

To succeed in this mission, the focal company must be able to manage and assess the risks that may be encountered during the collaboration. It must consider its abilities, constraints and dependencies at the early stages of the project to minimise all risks. The study of the dependency relationships between the focal company and its partners is an important step to avoid possible conflicts and malfunctions that may occur during the operational phase of product realisation. The research discussed in this paper shows firstly, the importance of enterprise networks, and then analyses dependencies between partners in order to understand the behaviour of the focal company and its global strategy.

Other products such as cars or personal computers are regularly improved through redesign, generation after generation; however, redesign never concerns only one or several instance(s). The main challenge presented in this paper is to provide a suitable framework to analyse one-off and batch upgrading processes. This framework targets at containing required concepts and drivers for upgrade problem posing. The axiom beneath this research is that the goal of upgradings is to improve the performances of products or systems. Upgrade-to-performance, UtP in short, represents this paradigm that will be defined and illustrated through examples. To reach this goal, necessary concepts are defined and linked together through a generic data model. The UtP data model can be used in a conceptual way clarifying the scope of the upgrading process. It can also be specialized to specific industrial domain and used as the main driver of the design of a database for a given upgrading projects. The use case reported concerns the conversion of a passenger train into an express freight where the focus is put on enlarging a coach' door. The results are then discussed to figure out the links between the UtP problem-posing and problem-solving methods and the gaps to fill. Finally, further research niches are described.

One or more changes can be applied to the products in order to improve, upgrade and adapt it to new requirements. These changes can have serious impacts. For one design change, some impacts can be predictable while others occur due to unexpected propagations on other parts of the product. Dealing with this risk, companies look for an approach to evaluate and model the propagation of changes impacts to minimize their consequences. The main objective of this work is to characterise this change impact by identification of the dependencies among product components, which is a first and necessary step to evaluate change propagation. We develop a novel approach based on Design Structure Matrix and graphs to identify and characterise the type of dependency existent between product parameters and compute the change propagation impacts. Our findings show that functional dependency is more detailed than quantitative and qualitative dependency characterisation, already used in the literature. A case of 2D geometric model of bicycle is presented at the end of paper.

Iterations are also necessary to fine-tune product definition during the initial design process. In both cases, engineering changes are the means by which the product evolves. However, changes are propagated from component to components and from function to functions, leading to nonvalue development activities with extra costs and delays. These engineering changes may have harmful impacts on industrialization and manufacturing; they can drastically hinder efforts to ensure faster time-to-market. Research works currently seek to model, predict, analyze, and assess the impacts of engineering changes and their propagations. This article focuses on changes in a two-dimensional geometrical product model and proposes a new change prediction approach based on two steps. First, the dependencies between the parameters of structural components are identified through experiments. These dependencies are characterized qualitatively, quantitatively, and by formal equations. The changes are then propagated through the network of dependencies, and their consequences are computed. A geometric two-dimensional model of a bicycle is used to illustrate the approach. The results are discussed, and the main contributions of the approach are highlighted while further research paths are presented at the end of this article.

The objective of this article is to compare the performance of two methods vs in solving a constrained facility layout problem. We consider their speed in relation to the performance of the obtained solutions, after their convergence, in terms of the total distance traveled by the parts in the workshop. The two chosen metaheuristics have been successfully applied in many search problems: the Genetic Algorithm (GA) and the Particle Swarm Optimization (PSO). In order to determine the shortest path between equipment in a given irregular area (with walls, obstacles, or fixed installations), the A* algorithm was combined with them. The comparison therefore concerns the two methods and . GA and PSO algorithms generate potential solutions for which the shortest path for any couple of machines is determined through the A* search algorithm by bypassing the obstacles. The mathematical model used and the parameters of the genetic algorithm are those developed in [1]. The numerical experiments demonstrate the feasibility and effectiveness of both approaches. The results show that GA provides better solutions in terms of fitness values while PSO is faster

Some systems have been operated for several years and the analysis work is very necessary for controlling and redesigning the system in purpose of getting better performances. In this paper we analyze the bike-sharing stations by clustering algorithms in order to mine the inner-station patterns, and these clustering results are essential for the system control and redesign. In this study, we take Vélib' bike sharing system in Paris as the study case.

To achieve this goal, it is necessary to manage the product life cycle activities especially the volume and variety of products which have to be easily customizable. Designing modular products increases the possibility of obtaining customizable products. The modular design consists of breaking down a product into more or less independent sub-elements called modules. This paper focuses on setting up a Genetic-based automatic product variants generator. The product used as the testbed is a LEGO plane composed of bricks. Different operators are used for selection, crossover and mutation of genes. Each final plane assembly is qualified based on some criteria to respect pre-defined constraints. The obtained final assemblies are discussed at the end of the paper to highlights future challenges.

They influence the product development and managers have to be able to control all the activities and their interactions that are generating the different processes. They have also to manage each actor involved in the project during the product lifecycle. In this paper, propose an approach to identify, define and manage factors influencing product development. It is the System Lifecycle Management. PEGASE, a prototype of software to control design project, follow-up the system evolution and support decision-making, is also presented.

Companies run frequently such projects but not all of them are able to transform ideas into business success. One of these success factors is closely related to the efficiency of project co-ordination and management. This article deals with specific performance measures, namely conformity measures, which can be used as a powerful parameter for NPD projects management. We consider an NPD project as a network of services provided by actors to each other. According to this idea, a given conformity measure, defined for every couple of actors, qualifies the quality of the service provided by an actor to another. Conformity measures appraise then the satisfaction degree of an actor who contributes to NPD project workflows regarding his/her collaborators. These service-links among actors allow to define four main parameters: forward, backward, upward, downward conformity measures. Once defined, two of them are illustrated through case studies. The first one concerns bicycle design process. The second one refers to a very simplified linear manufacturing procedure of a French car manufacturer, PEUGEOT. For both cases, we propose a visual aggregation method which qualifies the global quality of the considered process.
