A two-stage algorithm is offered enabling us to locate the faulty circuit components and evaluate their values, considering the component tolerances. At first a preliminary diagnostic procedure is performed, under the assumption that the non-faulty components have nominal values, leading to approximate and tentative results. Then, they are corrected, taking into account the fact that the non-faulty components can assume arbitrary values within their tolerance ranges. This stage of the algorithm is carried out using the linear programming method. As a result some ranges are obtained including possible values of the faulty components. The proposed approach is illustrated with two numerical examples.}, type={Artykuły / Articles}, title={Multiple Soft Fault Diagnosis of Nonlinear DC Circuits Considering Component Tolerances}, URL={http://journals.pan.pl/Content/89789/PDF/Journal10178-VolumeXVIII%20Issue3_02paper.pdf}, doi={10.2478/v10178-011-0002-1}, keywords={analog circuits, fault diagnosis, multiple faults, nonlinear circuits}, }
