However, demand forecasting is certainly not an easy task for a manager who had the choice between using traditional forecasting techniques encompassing time series methods, causal methods or simulation methods, or techniques based on artificial intelligence like artificial neural networks (ANNs), fuzzy logic or adaptive neuro fuzzy inference system (ANFIS). This paper focuses on the implementation and configuration of the artificial intelligence of neural networks, and more precisely the multi layer perceptron{\textquoteright}s structure, as a prediction system to produce daily demand forecasts based on historical demand information.

This exact solving method well-known, will serve us to test and validate our new problem formulation.

For improving solution quality, the LNS method will complete the GCDF. Computational results are presented at the end using instances that we have created under some criteria of difficulties or adapted from those of p-median problems available in literature. The GCDF{*} (GCDF improved) algorithm is fast and provides good results for most degree of difficulty instances, but it is unreliable for very specific cases.
