Analytical method for calculating the sensitivity index of system parameters

This work proposes an analytical method for calculating sensitivity index. The proposed method is based on oneat-a-time measurements and calculates the difference between output values and the base solution to define the impact caused by each parameter in the system. The results indicated that the analytical method provides adequate values for the sensitivity index even when the parameters have minor variation in relation to the base value, presenting coherent response with graphical analysis. The proposed method satisfies a wide range of systems and assigns value to the influence of the parameters, contributing to the decision-making process, calculation of system complexity, identification of systems, among other situations
