Use of the Pareto principle to assess system sensitivity

Abstract

Generally, the sensitivity of physical systems has been investigated using sensitivity function W(x). On the other hand, this paper uses a modified Pareto principle to examine the sensitivity of two systems: a part of a medium–voltage electricity network with wind turbines and a steel beam rigidly fixed on one end subjected to a uniform load. In the first case, objective function Fp involved active power losses in in the power grid, whereas the second case concerned displacements of the end of the beam. In order to accurately define the ABC sets a digital filter with original software was used.
