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.
