International audienceThe automotive product is increasingly restricted by environmental regulations, including reducing emissions of CO2 and pollutants in exhaust pipes of vehicles. One solution implemented in the automotive industry are plug-in hybrid electric vehicles (PHEV) that use an electric traction battery. To help vehicle manufacturers in their choice of traction battery from an environmental point of view, a simulation method of environmental impacts generated by the use phase is proposed in this paper. This method takes into account the possible usages of the vehicle and potential developments of electric mix, with the formulation of a constraint satisfaction problem (CSP) solved using constraint programming (CP) techniques. The sensitivity of five parameters is investigated: the electricity mix used to charge the battery, the battery mass, electric consumptions, the autonomy in " all-electric mode " , and the share of total travel in " all-electric mode ". Power grid is the most differentiating parameter for global warming and PHEV generates less impact if less used in " all-electric mode " on a high carbon intensity power grid. Lastly, CSP acausal modeling makes it possible to process different simulations with the same model

Part 20: Sustainable Collaborative Networks IInternational audienceSince the 2008 crisis, the automotive industry is shifting towards a new paradigm and repositioning around the green mobility, using mainly lithium battery technology. Given this new development, the issue of recycling batteries arises for ecological, economic and geostrategic reasons. Our work consists in formalizing a methodology to help design a sustainable recycling network applied to batteries, under uncertainty. The proposed approach involves two steps. The first step is about modeling the recycling network and the characterization of the problem’s elements, using systemic analysis. The second step consists in developing scenarios about the configurations of this value chain, and then optimizing their functioning. We’ll choose different positioning for the actors and make assumptions about logistic data. In this paper, we will try to summarize the issues of recycling lithium battery, explain in detail this approach and present the first results of application

Manufacturing companies are urged to take responsibility for their impacts on the environment and on society, to contribute to a more sustainable development. The concept of Corporate Social Responsibility (CSR) has therefore gained a lot of interest in the last decades. The Product Development Process (PDP) is a key activity in the operationalization of CSR in a company. However, little is known about the capabilities needed for companies to integrate and manage their CSR issues in their PDP. Therefore, this article aims at contributing to (1) identifying the capabilities to integrate and manage the CSR issues during the PDP, and (2) providing a maturity model to assess the level of capabilities for the integration of the CSR issues in the PDP. Insofar as CSR aims at contributing to sustainable development, the existing literature on capabilities for integrating sustainability in the PDP has been studied and taken as a basis to identify the capabilities for integrating and managing CSR in the PDP. A maturity model has then been built based on these capabilities. This contribution lays the foundation for a methodology to support companies in the improvement of their maturity level in terms of CSR-PDP interaction.

Car manufacturer's innovation teams are mainly focusing on decreasing automotive consumption and may lead to risks of transfers of environmental impacts. So, engineers in innovation should be able to evaluate their innovations in a life cycle and multi-criteria perspective. In this paper, Groupe PSA's approach for integrating the environmental dimension during the innovation phase is presented. An eco-design framework of reference has been developed in a collaborative manner by the environment team together with innovation leaders. It tackles both the issues of how to deploy environmental requirements in the innovation process, and how to generate an organizational learning. This methodology is explained through the example of the Stop and Start technology. The validation in the quality procedure is essential to make the approach sustainable.
