Introduction. Uncertainty on supply chains is an important factor that can influence the effectiveness of their configuration and coordination. A way to approach it in the design process of supply chains is taking into account the concept of robustness, understanding it as the preservation of certain desired characteristics in the system, in spite of the fluctuations in their components or in the environment. Objective. Evaluate the FePIA (Features, Perturbation, Impact, Analysis) procedure in the determination of the robustness in capacity planning and warehouse location problem in supply chains. Materials and methods. The FePIA procedure was evaluated by means of a multi-period mixed integer programming and of only one product model, applied on a supply chain composed of three links. Results. The application of such procedure allowed the definition of robustness requirements, performance features and perturbation parameters. It was not possible, however, to find a general relationship between the perturbation parameters and the performance features for 62% of the instances used. Therefore, it was not possible to obtain a robustness region with the original methodology. Further analysis could demonstrate that the structure of the chain is associated to that problem. Conclusions. The FePIA procedure must suffer modifications for being fully applied to the capacity planning and warehouse location problem in supply chains.
