Production à flux tirés dans une chaîne logistique

Abstract

The choice of a production management between a pull-flow approach and a push-pull approach is less simple than it seems when we take into account the perimeter of the logistics chains. In fact, it is generally necessary to combine these two management methods in order to meet increasingly short customer deadlines as well as possible without increasing costs. These couplings are not independent of the characteristics of the logistics chain, of the products to be manufactured and of the regularity of demand, and calls for different forms of management. We will examine here one of the most well-known approaches, the kanban system, which has been used successfully under certain conditions, in particular that of the stability of demand. We will analyze the use of the kanban system in environments violating the assumptions conventionally made in this field, which will make it possible to highlight the conditions of robustness of this type of piloting. The questioning of the cruising regime in the kanban system somewhat complicates the analysis of the modalities of flow management on the logistics chain and pushes to imagine new management rules to allow the synchronization of productions in the logistics chain.
