The diagnosis of firm´s “Diseases” using the grey systems theory methods

The core of our proposal is the determination of a "matrix of symptoms", based on grey systems theory. The symptoms of a firm can be represented by economic-financial ratios, usually used by analysts to make predictions and suggestions. The ability to create such a matrix of symptoms implies that given level of symptom\´s intensity, we can determinate if the analyzed firm presents some "diseases". By diseases we understand the causes which generate anomalies at the firm. With the utilization of such a matrix, the activity of the analyst can be really improved.
