  1 - Provide a mathematical model for selecting suppliers in the supply chain based on profit efficiency calculations

  One of the most important issues in managers' decisions is supplier selection and supply chain evaluation. Therefore, several studies have been conducted on supplier selection and evaluation by data envelopment analysis. But studies so far have focused on selecting suppliers and evaluating them. And there is no way to determine the number of suppliers in a supply chain. Therefore, in this article, we first express the concept of profit efficiency for supply chains and using the proposed model in this paper, the number and type of suppliers in a supply chain are determined simultaneously. Finally, 10 "supply chains" in the food industry were examined and the profit efficiency of each of them was calculated using the proposed model in this article, and then the number and type of suppliers in each chain were determined.

  2 - Measuring robust overall profit efficiency with uncertainty in input and output price vectors

  The classic overall profit needs precise information of inputs, outputs, inputs and outputs price vectors. In real word, all data are not certain. Therefore, in this case, stochastic and fuzzy methods use for measuring overall profit efficiency. These methods require more information about the data such as probability distribution function or data membership function, which in some cases may not have sufficient information to estimate them, and only we have knowledge about the parameters so that they change in a convex space that is closed and bounded. Therefore, in this paper, we consider a budget uncertainty model in the robust optimization problem that able to adjust the conservative degree. The robust model by the input and output price vectors is proposed to compute overall profit efficiency measure. To illustrate the application of the proposed method, a numerical example is presented and the results show that the robust overall efficiency of the decision making units is higher than the optimistic model.

  3 - The proposed cost and profit models in presence of flexible measures
  F. Matroud Gh. Tohidi
  In conventional DEA, measures are classified as either input or output. However, in some real cases there are variables whose status is not known as input or output before assessment. These variable are known as flexible measures. One of the most important economic dim More

  In conventional DEA, measures are classified as either input or output. However, in some real cases there are variables whose status is not known as input or output before assessment. These variable are known as flexible measures. One of the most important economic dimensions for ensuring the success of a company is the efficiency with which it uses its resources. Therefore, centering on Assessment costs and profit of financial institutions is an important issue. Aware of the importance of this subject, we propose the cost and profit efficiency model in presence of flexible measures due to the many application of these variables in real world. The proposed models determine the status of each flexible measure as an input or output statue and simultaneously maximize profit/minimize cost in profit/cost model. In order to evaluate the capability model the proposed model are applied to a real-life data set of 50 U.S. banks. Manuscript profile

  Regarding the special role of banks in the economic system of countries and the world, there are considerable regulatory and control rules applied to them. With the rise and growth of Islamic banking, various studies and studies have been conducted to analyze the performance and regulatory mechanisms of this industry. The rules of the Basel 2 agreement are among the most important in the international agreement, which is designed to provide banking security. Among the issues raised in this agreement, the observance of minimum capital adequacy has received much research attention. Given the inherent differences and constraints facing Islamic banks in Iran, Basel Committee's capital ratios may not necessarily be appropriate for this banking system. Then, by modeling its impact on bank profitability as the most important motivational index of banks, its optimal value for the Iranian banking system is determined. The results show that the designed model is well able to explain the relationship between capital adequacy and profit efficiency and the optimal capital adequacy ratio for optimizing bank profit efficiency was estimated at 12.5%.In the same way that healthy and efficient banks can be effective in economic growth, their unhealthy and poor performance can also lead to financial and economic crises. The WFTC has been reviewing and proposing capital requirements since 1988 and, most importantly, observing the minimum capital adequacy of banks. Calculation of capital adequacy requires consideration of capital and risk weighted assets. Due to the significant difference between the methods of financing and the use of funds and the type of contracts and payloads in the Islamic bank with the conventional bank, it is necessary to calculate and determine the minimum capital adequacy for an Islamic bank after identifying and classifying various types of assets, liabilities and capital And the amount of risk associated with each of them, taking into account its specific financial features. Therefore, this research intends to assess the suitability of a set of the most important indicators of banking healthy indicators, namely, capital ratios. To this end, the ratio of capital ratios (tire1+tire2) to risk weighted assets with technical efficiency of Islamic banks of Iran is reviewed. After calculating the technical efficiency index of banks by CCR and BCC, eight panel data regression models for the period 2003-2015 were estimated for 21 banks and more than 190 statistical samples. The results show that all four capital indicators have a positive and significant effect on the technical efficiency of the banks. However, tire1 capital to total assets ratio is the best explanatory variable among capital ratios for banking performance. Manuscript profile
