  Abstract Portfolio selection is one of the most important areas in financial decision-making; A portfolio of stocks that could bring the highest rate of return and the lowest risk investment for its owner simultaneously. However in choosing the most prefered portfolio just these factors are not decisive and according to the economic environment, many factors can affect this process which should be employed. Therefore, these diversity of factors, bring to the limelight the importance of multi-criteria decision-making approaches. Data Envelopment Analysis (DEA) is one of this approaches. The main purpose of this paper is comparing the traditional DEA approaches to a new proposed algorithm. In traditional approaches simply assumed that return to scale is constant or variable. This simplification may cause large errors. In the new algorithm by analyzing the behavior of return to scale, appropriate model will be used. As a case study, the models have been solved with real data belonging to Tehran stock exchange and the results have been analyzed. Manuscript profile

  According to strategic importance of performance assessment, today a few limited numbers of organizations are going to guarantee the improvements of their personnel’s performance through an appropriate evaluation of their staff. For this purpose, the current research was done in social security fund of Semnan province. This research has followed a descriptive goal (based on a case study) with a comparative logic through a limited applicable process which is considered to be as the most crucial selected method in order to extract the information of documents and the organization. Receipt, tables and diagrams are referred to as the most important tools applied in this paper. The fuzzy data envelopment analysis was selected as the most appropriate method for analyzing the data based on the studies done. The results in this research indicate that the current traditional systems of assessment in the social security fund of Semnan province does not have enough efficiency and it does not have any effect on the increase of willingness and tendency of the staff. Therefore, a new system of assessment which was compiled on the basis of the fuzzy data envelopment analysis was represented to substitute the traditional system. This model had some strong points such as the personnel assessment without the manager`s verdict, having the ability to perform under the circumstance of uncertainly, the probable presence of an ideal virtual unit, and the evaluation of personnel based on the predetermined objects. There is a hope to see this part of the health services management to become more represented in the future by the conduction of the suggested assessment system in the research society.

  Most organizations to increase productivity and ultimately achieve sustainable competitive advantage for survival in the global business arena, focusing much of their attention to fix the problems, difficulties and weaknesses in their own systems and processes. Organizations spend a lot of time and resources to plan and develop their own strategies, but most of them fail in the implementation of the strategy.Organizations are looking for a breakthrough performance through integrated processes and technology to respond to the needs of our customers. The use of Lean Six Sigma methodology for organizations that operate in a competitive world is very functional. The importance of implementing Lean Six Sigma in an organization that is in issue or to be discovered process properly investigated and the selection process to the strategic objectives of the organization so that the organization can be targeted to improve process performance and take steps towards continuous improvement. The purpose of this research is a strategic process through the accounting department processes to improve performance through the application of Six Sigma methodology Ghavamin Bank was pure. Therefore, in this study, the criteria for the selection process to select a strategic process through six main measure Balanced Scorecard and by experts Ghavamin Bank, were identified. Then processes information related to the accounting department of the bank through a database of Ghavamin as well as interviews with experts were collected Bank. The final step using cross efficiency DEA model to assess the efficiency of the process was done, the results showed that the process was No. 18 in the first place. And as the bank's strategic process to make continuous improvement in the Lean Six Sigma methodology was introduced. Manuscript profile

  Network data envelopment analysis models and dynamic network data envelopment analysis models cannot evaluated the future performance of the internal structure of decision-making units .In other words, all NDEA and DNDEA models evaluate the past performance of their DMUs and their internal structure, and measure their efficiency and inefficiency, and ultimately rank them based on that assessment .In this paper, we are going to evaluation the future efficiency of deposit and lending sections in bank branches. In order to notified inefficiencies in the internal structure of a unit before the occurrence, we will prevent it.This approach can change the role of managers from the evaluator to the planner .First, using the literature of the subject and opinion of the experts, the structure of the bank branches and the network variables were determined .Then, the values of variables are forecasted using the artificial neural network for the next two periods.Finally, a DNDEA model is formulated using the values of past periods and predicted values.Using its efficiency, its branches and its internal structure have been evaluated in the past, present and future.

  Establishment of the modern managerial systems is one of the most important steps for the excellence of organizations. The European Foundation of Quality Management (EFQM) is one of the technics that has started from Europe during the two recent decades and nowadays many organizations are in the process of implementing this model with- in their managerial domain. Data Envelopment Analysis (DEA) is a known nonparametric tool for evaluating the organization’s efficiency. In addition to having the capability to measure the total efficiency of a system, network DEA is able to calculate the efficiency of system components. Since EFQM can be considered as a multi-stage system, existence of network DEA along with it can improve the analysis. In this paper, an integrated model has been suggested based on EFQM and Network DEA for assessing the organization’s operation. For this purpose, at first the EFQM has been considered as a ‘four-stage system’ including leadership (the first stage), activities related to employees, policy, strategy and partnership (the second stage), processes (the third stage), and results (the fourth stage). Then considering 32 sub-criteria in EFQM, input and output variables have been determined for each one of the four stage s and on this basis math form for Network DEA model has been developed for this 4-satge system.
