The proposed model generates a strategic profile of the company which is a graphic representation that reflects the valuation given as a fixed scale for each aspect of the different functional areas identified as most relevant. This is the initial part of a research project that will include the development of a competitive model for diagnosis and prediction using a fuzzy approach and evolution strategies for optimization and contrast with the field data
