Abstract
The French automotive industry is one of the best drivers of the country. Around 2.5 million people have a job directly or indirectly (energy, insurance, advertisement) linked to this activity and it represents 20% of the plus-value industry. This industry is divided into two parts: 66% concerning the construction of cars and 33% the production of equipment. The allocation of resources respects this proportion. Mass-producing is the base of automobile construction. With the diversification of the models, manufacturers have adopted a platform policy that pools the constructions of the elements that cannot see the client. It allows for the reduction of costs.
