Purpose: Efficiency is an economic concept which shows the performance of a wide range of economic activities in different areas of an economic sector. Most of studies using frontier technique Data Envelopment Analysis (DEA) do not test for the relationship of efficiency estimation with key performance indicators. This is despite the fact that DEA is one of the most effective tools for measuring and evaluating efficiency. Nevertheless, identifying the relationship between efficiency estimates and commonly accepted financial measures of performance could guide benchmarking activities, pricing decisions, and regulatory monitoring.Methodology: In this paper, the DEA super-efficiency formula is tested in two profitability models. Four ratios of net interest income to total assets, post-tax profit to total assets, owner’s equity returns and impaired loans to total assets, were calculated with a developed profitability model; besides, the growth rate of assets was calculated with main profitability model and all the aforementioned ratios addressed a significant association with efficiency estimates.Findings: In this study, the DEA super-efficiency formula is tested in two profitability models for 15 banks for two years. The correlation obtained is generally low. However, the four ratios of net interest income to total assets, post-tax profit to total assets, owner’s equity returns and impaired loans to total assets, in the EPM model and asset growth rate in the CPM model have a significant relationship with performance estimates. Finally, the results indicate poor credit quality in Iranian banks in 1397-1397.Originality/Value: In this study, for the first time, the nature of the relationship between performance and key performance indicators has been estimated. DEA technique has been used to purposefully identify criteria for analyzing financial ratios.

One way to reduce investment risk is to form assets portfolio. In this study, a multi-criteria analysis is employed to select equities using ANP method. For this purpose, listed firms in Tehran Stock Exchange were divided into six industrial groups and their data collected between 2016 and 2017 to calculate financial ratios and then two ranking methods such as DEMATEL and ANP were employed. The aim of this study is to use financial ratios as key indicators to find out their interactions using DEMATEL method, and then to recognize the importance of identifying indicators, we have used ANP techniques to determine weight of the variables. Finally, after collecting data related to selected financial indices and obtained weights, number of 185 companies in six separated industries were ranked by Excel software and their priority in both total companies and related industries was identified. The results can be used by investors, investment funds and financial advisors to determine the optimal portfolio and help to identify superior companies.
