Example 2.4. Model-building of COSS “net current assets/turnover assets ratio”.
Data on audit and analysis of enterprises of machine-building and food industries,
and of telecommunications facilities production enterprises was used. The net
current assets/turnover assets ratio was studied for each enterprise. Based on the
analysis carried out, let us construct COSS “net current assets/turnover assets
ratio” using terms "very low", "low", "average", "high", "very high". The experts
who surveyed the enterprises were provided with intervals of U ratio values,
which are typical for every term
