Multimodel approach: Validities' computation by local criterion optimization

The evaluation of validities is a fundamental step in the design of the multimodel approach. Indeed, it is thanks to validities that we estimate the contribution of each base-model in the reproduction of the behavior of the global process in a given operating area. In this paper, we propose a new method of base-models' validities computation. This method is based on the optimization of a local criterion. Simulations examples showed the interest and the effectiveness of the proposed method.
