Risk management to support collaboration inside the supply chain: a simulation approach ; Management des risques pour l'aide à la gestion de la collaboration au sein d'une chaîne logistique : une approche par simulation

Collaboration in the supply chain belongs to a particular context defined by risky events, information exchanges (more or less efficient) and influence games between partners. Then, we can define collaboration by three key dimensions: internal behaviors (individual decision processes), protocols (shared processes) and risky events (scrap, breakdown, market variability.) that imply uncertain supply chain performance. In order to anticipate the potential consequences of several situations, the consequences of decisions (behaviors and protocols) and/or events on the partnership have to be represented and evaluated. As a prospection tool, the simulation of the actors' planning processes in the supply chain allows an a priori assessment of the supply chain performance. The functionalities of a discrete event simulation tool based on a multi-agents system have been extended to new behaviors and protocols or uncertain events met in the reality. The expression "collaboration support" makes reference to the integration of the simulation results in a global risk management process in order to configure protocols and behaviors inside the collaboration. Several methods and tools have been developed to model the configuration decision process and give the decision-maker relevant information about his decision situation (decision trees, decision criteria.). This decision process is intrinsically subjective. The tools and methods proposed integrate this subjectivity: (i) choice of performance indicators used to decide, (ii) the attitude of actors to uncertainty, (iii) capacity to take into account the "others" in terms of their own risk perception and performance objectives, and (iv) the global sequence of decisions and events. The last chapter illustrates the method proposed thanks to an application on the collaboration between Pierre- Fabre laboratories and its packaging suppliers. ; La " collaboration au sein d'une chaîne logistique " s'exprime dans un contexte particulier fait d'aléas, d'échanges d'informations plus ou ...
