ESTABLISHING THE MOST INFLUENCING CAUSES OF COMPANIES’ FINANCIAL HEALTH AND PERFORMANCE – A GREY FUZZY APPROACH

The core of our paperwork consists in construction of a model for determining a hierarchy of qualitative and quantitative causes that are influencing service companies’ financial health. While the quantitative causes are objectively measurable, the qualitative causes are mainly subjectively measurable, quantified based on some experts’ opinion. In order to reduce the degree of subjectivity, we took advantage of methods offered by fuzzy systems, mainly in construction of the expertons. Expertons are in fact intervals built using the ϕ-fuzzy sub-set and the opinion of several experts over a certain problem. Furthermore, after constructing the expertons, we use the methods offered by grey systems theory and fuzzy sub-sets arithmetic to determine the degree of influence of each qualitative and quantitative cause on company’s performance. By classifying the causes and acting on the most important of them, the activity of the analyst can be really improved and the company’s performance will rise.
