David Damand, associate professor at EMSBS, recently published an article in the Journal of Production Research [CNRS cat. 2, FNEGE cat. 2, HCERES cat. A].
The article is entitled "Parameterisation of demand-driven material requirements planning: a multi-objective genetic algorithm" and was written in collaboration with Marc Barth (EMSBS) and Youssef Lahrichi (EMSBS).
Demand-Driven Material Requirements Planning (DDMRP) is a recent inventory management method that has generated considerable interest in both academia and industry. Many recent papers have demonstrated the superiority of DDMRP over classical methods like MRP or Kanban, an observation confirmed by companies that have implemented DDMRP. However, DDMRP depends on many parameters that affect its performance. Only general rules are given by the authors of the method to fix these parameters but no algorithm. The present paper aims to fill this gap by proposing a multi-objective optimisation algorithm to fix a set of eight identified parameters. The suggested genetic algorithm is coupled with a simulation algorithm that computes the objective functions. Two opposing objective functions are considered: first, the maximisation of orders delivered on-time to the customer and, second, the minimisation of on-hand inventory. A set of data instances was generated to test the suggested method. Fronts of non-dominated solutions are found for all these instances.
