A mechatronic system is an intelligent product that is usually very complex and deserves to be characterized. The complexity comes from the number of integration of functions in a single product. Mechatronizability, which is the ability of the degree of mechatronics of a system, is a remarkable characteristic for designers to decide the level of complexity at the design stage of multifunctional products. The concern is therefore to estimate the multifunctional degree of a mechatronic product. After the description and analysis of a mechatronic system, two methodological approaches are proposed based on three metric models: the functional integration indicator which reflects the degree of collaboration of components in the realization of functions of a product. The functional complexity indicator which reflects the level of interpenetration between the elements belonging to the different domains existing in each of the product functions. The functional dematerialization indicator which measures the degree of integration of electronic "E", computer "I" and automatic "A" areas in a product. These indicators have been applied to a hydraulic pump. The designer will now have to know the mechatronizability of a product to decide on its degree of intelligence.

Competitiveness pushes companies to redefine their production units to offer multifunctional products. The integration of several functions requires the marriage of several disciplines of mechatronics that it is necessary to measure its dimension of integration. Because the problem of the designers or the professionals of the mechatronics is the one to know the level or the degree of the mechatronics which reflects equipment conceived or to be conceived for the market remains a necessity. This study seeks to understand the complexity of a mechatronic architecture to identify its constituents and define the parameters of a mechatronic system to estimate the mechatronizability of a product. After defining the utility and objectives of the metric, a methodology for the identification of the influential parameters and the formulation of the metric has been proposed. Drawing on the debatable achievements of the literature, four indicators were defined. In particular, the indicator of functional integration, dematerialization, complexity, and the general degree of mechatronics. These metrics of simple formulation were applied and validated on an electric pruning shear to estimate its mechatronic dimension. These metrics should allow manufacturers to simulate the mechatronic dimension of their production units and their competitive products.
