Aplicación de la metodología DMAIC de Seis Sigma con simulación discreta y técnicas multicriterio

In this paper we show the results achieved by integrating Six Sigma, discrete simulation techniques and multi-criteria techniques for improving a beauty service that desires to obtain the best compromise solution between incomes, costs, use of resources and customer satisfaction. DMAIC methodology was used to propose a procedure that defines, for each phase, simulation tools, multi-attribute decision making, statistics and quality control and management. The use of simulation allowed us to analyze the different actions for improvements and determine the values of the variables of interest being defined by the administrative group. We used, between multi-criteria techniques, PRES index for ranking the actions according to experts’ preferences
