The Enterprise Actor Model (MADE) is the product of five years of research by the research group in development in Industrial Automation at the University of Cauca, Colombia. It is a model of enterprise integration developed specifically for production-sector businesses. It aims to represent the structure, behavior, organization and integration of the components of a production business, while establishing the information that flows among them. Achieving a successful application of this model to a particular production business would become a major contribution to the field of automation and enterprise integration. A series of works has developed around MADE that gradually allowed to add new features, definitions and concepts; however, the degree of formalization required to initiate the process of developing a methodology for implementation has not yet been achieved. This article focuses on formalizing the existing components of the Enterprise Actor Model which results in three basic elements of MADE: entities, nomenclature of entities, and models.
