Introduces rational culture as the dominant organizational culture. Also, the maximum and minimum effectiveness are related to the variables of e-government and power distribution.

Cross-efficiency method is a useful tool for efficiency evaluation of decision-making units in data envelopment analysis. The issue of non-uniqueness of optimal weights in the cross-efficiency evaluation has reduced the usefulness of this powerful method. This paper introduces a new method for selection of weights profiles as the secondary goal in cross-efficiency with stochastic data. The issue of zero-weight which implies the exclusion of some variables from the assessments, is also addressed in the new proposed method. The provided weights selection method also reduces the weight disparity in the achieved weights profile. In the peer-restricted stochastic cross-efficiency evaluation, the new approach guarantees that different DMUs should not attach very different weights to the same variables. As the result, a common set of weights using the idea of similarity between sets of weights is achieved in the proposed computation method. Some numerical examples are also used for illustration and comparison purposes.

Performance evaluation of the production systems by considering data related to different time periods is one of the most important issues of production theory. In this paper, a new method for measuring the aggregative efficiency of multi-period production systems using the data envelopment analysis (DEA) technique is proposed. The provided approach could be considered as extension of the radial methods in the literature. An extended Russell based model is presented for the first time to measure aggregative efficiency with respect to the time intervals of the production stages. One of the useful features of the proposed model is that the inefficiency of the existing aggregative approach is detected in one step without need to account for the second stage of optimizing slack variables. Some properties and advantages of the new model is discussed. Finally, to illustrate the applicability of the new approach, two practical examples are investigated and analyzed. The results show the good performance of the proposed method.

Research shows that in the general part, rational culture and in the specific part, adhocracy culture are the dominant organizational cultures. The common denominator between the general and specific sections is that both sections, general and specific, focus on the external environment, with the difference that the general section emphasizes on the stability and uniformity, and the special section emphasizes on the flexibility and non-uniformity. Also in the general and specific sectors, the most effectiveness is related to the E-government, creativity and innovation variables, respectively.

All change, whether from internal or external sources, large or small, requires new ways of thinking, processes, policies, practices and behaviors. But today, the most challenging task that managers face is the ability to create a managerial and cultural style that can cope with these changes, the changes that organizations must apply today, both incremental changes and transformational changes. The present is the analysis of executive models of organizational improvement.

In this research, we seek to find a detailed description of a phenomenon that we know but do not understand all its dimensions. In other words, this research is descriptive in terms of strategy and purpose, qualitative in terms of approach, and library and non-laboratory in terms of location.

An organization culture implies that all members of the organization understand the organization in the same way, and it is also a good way to operate, manage and change it.

A key factor in the successful implementation of key improvement strategies as well as adaptation to the growing environmental turmoil that modern organizations face is organizational culture reform.

Efficiency and effectiveness as the output of human and organizational systems is achieved when work and behavioral processes are modified, on the other hand, a key factor in the successful implementation of key improvement strategies as well as adaptation to the increasing environmental turmoil with which modern organizations Facing reform in organizational culture.

Effective and efficient human resource management is critical to the success of any organization. Meanwhile, improving employee performance is one of the main concerns of organizations in the public sector.

The aim of this study is to design a high commitment human resource management (HC-HRM) model among the employees of the 14 regions of Education Department in Qazvin Province. The statistical sample consisted of 260 employees who were selected according to the Morgan table. The present study was of a survey type. Data analysis was performed by applying structural equation modeling and Smart PLS2 software. 

Research results show that perceived high commitment human resource management directly and positively affects individual performance. In addition, research findings indicate that the variables of work engagement, professional commitment, and perceived organizational support play a role in the relationship between high commitment human resource management and individual performance as mediators. 

No doubt, the findings of this study enhance the knowledge of high commitment human resource management; besides, by modeling perceived high commitment human resource management at individual level, it helps create a new knowledge domain in the related literature.

Enhancing employee performance is of great concern among state organizations. The purpose of this article is to study the impact of perceived committed HRM on individual performance with the mediating roles of job stress and job commitment and the moderating roles of job skills and perceived supervisor support among the employees of the Education Department of Qazvin Province. Based on Morgan’s Table, 260 subjects comprised the statistical sample. It was a survey study and questionnaires were applied to gather data. Data analysis was performed through structural equation modeling based on variance analysis. Findings indicate that there is direct relation between committed HRM and employee performance; the mediating role of job commitment between perceived committed HRM and employee performance is positive and significant, but work stress plays no mediating role between these latter variables. Moreover, regarding the amount of the statistic “t”, the moderating role of perceived supervisor support between perceived committed HRM and work stress is positive and significant; however, job skills play no moderating role between perceived committed HRM and job commitment.

 Hospitals, as one of the main organizations providing health services, have a special sensitivity and importance in the economy and health. Full attention to the efficiency of the hospital as the largest and most costly operational unit of the health system is of particular importance, so the evaluation of hospitals is one of the most important issues for health policy makers.

Data Envelopment Analysis (DEA) is a method for evaluating the efficiency and productivity of decision units. If a network is composed of interdependent steps to generate outputs. Therefore, in this study, we have evaluated the relative efficiency of hospitals with output weight constraints for those outputs that have non-linear values. Equivalently, in the cover form, the give-and-take principle is used to take into account the output constraints. In this way, an ascending weight sequence is considered for larger output values of nonlinear value. This study is examined in a secret network. In this study, using the network data envelopment analysis approach, a system performance evaluation model has been designed that considers the relationship between weights as a reliable area in the evaluation.

In this article, the efficiency of 10 hospitals is examined with a new approach, of which only the fourth hospital has obtained an efficiency score of 1. An important feature is the change in the type of classification of efficient and inefficient units in the findings. The results showed that the proposed method is more accurate because by considering nonlinear pricing, it reduces the error that results from linear pricing in evaluations.

The resulting efficient and inefficient units are different from the previous classical methods, so different policies for the units must be considered by managers.

One of the important goals of banks as important economic enterprises of any country is to increase economic efficiency. One of the important goals of banks as important economic enterprises of any country is to increase economic efficiency. The classical approach to data envelopment analysis models takes into account the linear valuation function for all indicators. But linear valuation in many examples of the world around us does not represent the non-linear nature of the indexes. Therefore, in this paper, we have introduced the principles of the model based on slack variables, some of which have nonlinear values. In a practical example of a bank, we reviewed the efficiency of ten branches of one of the country's banks in 1395 with a new approach. One of the important goals of banks as important economic enterprises of any country is to increase economic efficiency. One of the important goals of banks as important economic enterprises of any country is to increase economic efficiency.

Considering the existence of major faults in Tehran and probability of devastating earthquakes in this area, it seems essential to provide strategies for confronting the crisis and to manage the damages. Therefore, this paper aims to identify urban crisis management strategies in Eslamshahr County. In this descriptive analytic study, by using the SWOT, the strengths, weaknesses, opportunities, and threats points of urban crisis management were studies in Eslamshahr County and optimized strategies were developed. Then, the strategies were ranked by using DEA (data envelopment analysis), a nonparametric method based on mathematical modeling. The findings showed that the final score of organization was 2.1 and 2.46 respectively according to the results of internal and external factors evaluation matrix analyzing. It was found that the strengths are less than weak points and available opportunities are less than threats in Eslamshahr county crisis management. Of the 25 SWOT-based strategies that prioritized by using DEA, the strategies of ST1 and ST2 had the highest priority. The results presented that strategies such as the use of specialized human resources to promote awareness, education, and safety culturalize as well as strengthening and empowering the crisis management unit in Eslamshahr county municipalities are the most important strategies

Nowadays, managing a supply chain is turned to be one of the fundamentals of business process. In doing so, investigating and analyzing each and every of the processes and selecting the best of each process is an important challenge for strategic managers. In this paper Data Envelopment Analysis (DEA) technique is used and a model is provided for selecting the best suppliers with flexible inputs and outputs. Here, suppliers according to the different requirements of the next stage can be flexible for providing the already forecasting alterations. As an instance, transporting one of the flexible outputs can be considered which can be sent from the earth, sea, or the air. This has the direct effect on the selection of the best suppliers and according to this selection the new chain will be selected in accordance to the requirements of the whole chain. In this paper, according to DEA models and the binary algorithm, a new model will be presented for suppliers.

Data Envelopment Analysis (DEA) is a mathematical programming technique for evaluating the relative efficiency of a set of Decision Making Units (DMUs) and can also be utilized for setting target. Target setting is one of the important subjects since according to its results efficiency can be increased. An important issue to be currently discussed, is to set target while considering share data. These data for each individual indicate the share of the unit, which takes part in an activity, from the whole amount which is a predefined constant. It is obvious that the sum of units’ share is equal to the entire amount. Thus, any changes in the magnitude of these data has to be dependent on the changes in data of other units. In this paper a two-stage procedure is developed to find benchmark units where share data exist. The fact that all DMUs are jointly projected onto the new efficient frontier and simplicity, are the significant features of the proposed method. With a numerical example we demonstrate how this method works.
