One of the tools for evaluating financial power to investment in companies is using analysis of financial ratios and obtaining the patterns for predicting the bankruptcy of companies. The purpose of this study is to modify the current patterns for predicting bankruptcy in proportion to the environmental status of Iran and to present a new pattern for determining the bankruptcy of the listed companies.
To modify the patterns and present a new pattern, in this research, the hypotheses pertinent to the ability for right classification of the companies are designed by the modified patterns of predicting the company’s bankruptcy and ranking, that is according to the envelopment analysis method and by comparison of the results and presenting a new prediction pattern.
