Los indicadores como variables en los análisis de eficiencia en la minería del níquel en Cuba.

The purpose of this research was to propose variables to be used as a basis for analyzing efficiency in the nickel mining. Compared to the rest of the world, in Cuba the application of mathematical methods that do not require specification of a functional form has been limited, so this research proposes Data Envelopment Analysis as an effective benchmarking tool. This technique makes it possible to identify elements that determine the establishment of goals and contributes to the development of action plans that allow companies to be efficient in an environmentally responsible manne Based on the results, it is proposed to use the tons of nickel produced in Cuba as a product variable in the efficiency analysis. The technical indicators such as input or resource variables and the technical indicators (capital productivity), expressed through the Global Effectiveness of the Equipment (OEE), and labor productivity, as well as the economic and environmental indicators that are better weighted in the selected units.
