Définition et gestion de produits semi-finis en vue d'une production de type "assemblage à la commande"

Abstract : This PhD thesis addresses the problem of the set-up of a stock policy adapted to a huge diversity context. We propose to include the notion of information levels into the classical question of design and inventory management. When product diversity enlarges, choosing
an Assemble To Order policy offers a good compromise between product portfolio size and assembly lead time. We propose methods to help set up this policy. Actually this implementation raises the following question: How to make the set-up using the available information? This question can be split up in two:
How to choose the modules to stock?
How to size stocks?
Huge diversity also has a powerful impact on information. Therefore, our work enables to take into account different information levels. This study also aims at observing the advantage of information on final products demand. Therefore we
- model information about demand with an hierarchical point of view
- develop an entropy-based method to construct information about final demand from available information
- propose heuristics for the choice of modules
- study the inventory problem on didactical examples
By those means we propose methods to deal with the two questions of ATO set-up.
Thanks to tests, we also stress the value of information.
